For the die-hard developers out there, we are pleased to introduce a new version of Incredible PBX™ for Asterisk-GUI that uses GIT repos to build both Asterisk® and Asterisk-GUI with the same feature set of applications as our previous releases. You still get a Gotcha-Free PBX with pure and honest open source GPL code. No patent, trademark, or copyright minefields to trip you up. But this time around you’ll have an Asterisk platform that can be updated in seconds by running a simple upgrade script: upgrade-asterisk-to-current. Special thanks to Matt Jordan & Co. for the new GIT implementation. And our extra special thanks to Denver sports cartoonist, Drew Litton, for letting us share his GIT-R-DONE creation as well.

This time around you’ll need a 64-bit CentOS 6.5/6.6 base platform. When you complete the 30-minute install procedure, you’ll have the very latest version of Asterisk 11 and Asterisk-GUI. Both are compiled from source on your hardware platform to maximize performance. The end result is the VoIP Trifecta… better, cheaper, and faster.

Since the early Windows® days, we haven’t been big fans of GUI-only interfaces. Let’s face it. Some things can be configured more efficiently with less chance for error using other tools. Incredible PBX takes advantage of this hybrid technology by offering the best of all worlds. Administrators can use a GUI where it makes sense and use a text editor or simple web form where it doesn’t. There’s no MySQL middleware to obfuscate your Asterisk settings. So you can configure 8 VoIP trunks from 8 great providers in under 5 minutes. And there’s so much more…

Target Audience: Home or SOHO/SBO in need of a turnkey, Gotcha-Free PBX Development Platform Default Configuration: Asterisk 11 with enhanced Asterisk-GUI, Kennonsoft GUI, and NANPA dialplan Platform: 64-bit CentOS 6.5/6.6 running on Dedicated Server, Cloud-Based Server, or Virtual Machine Minimum Memory: 512MB Recommended Disk: 20GB+ Default Trunks: Google Voice, CallCentric, DIDlogic, Future-Nine, IPcomms, Les.net, Vitelity, VoIP.ms1 Feature Set: Fax, SMS messaging, VPN, Reminders, ConfBridge Conferencing, AsteriDex, Voicemail, Email, IVR, News, Weather, Voice Dialer, Wolfram Alpha, Today in History, TM3 Firewall WhiteList, Speed Dialer, iNUM and SIP URI (free) worldwide calling, OpenCNAM CallerID lookups, DISA, Call Forwarding, CSV CDRs Administrator Utilities: Incredible Backup/Restore, Automatic Updater, Asterisk Upgrader, phpMyAdmin, Timezone Config, Plug-and-Play Trunk Configurator, WebMin, External IP Setup, Firewall WhiteList Tools

Getting Started with Incredible PBX for Asterisk-GUI (GIT Edition)

Here’s a quick overview of the installation and setup process for Incredible PBX for Asterisk-GUI:

1. Choose a Hardware Platform – Dedicated PC, Cloud, or Virtual Machine
2. Install Linux – 64-bit CentOS 6.5 or Scientific Linux Minimal ISO
3. Download and Install Incredible PBX for Asterisk-GUI
4. Install Incredible Fax for Asterisk-GUI (optional)
5. Set Up Passwords for Incredible PBX for Asterisk-GUI
6. Configure Trunks with Incredible PBX for Asterisk-GUI
7. Connect a Softphone to Incredible PBX for Asterisk-GUI

1. Choose a Platform for Incredible PBX for Asterisk-GUI

Incredible PBX for Asterisk-GUI works equally well on dedicated hardware or a virtual machine. Just be sure you’ve met the minimum requirements outlined above and that you have a sufficiently robust Internet connection to support 100Kb of download and upload bandwidth for each simultaneous call you wish to handle with your new PBX.

For Dedicated Hardware, we recommend an Atom-based PC of recent vintage with at least a 30GB drive and 4GB of RAM. That will take care of an office with 10-20 extensions and a half dozen or more simultaneous calls if you have the Internet bandwidth to support it.

For Cloud-Based Implementations, this time around we recommend Digital Ocean because the GIT edition is designed to be a development platform with bleeding edge Asterisk 11 code.

For Virtual Machine Installs, we recommend Oracle’s VirtualBox platform which runs atop almost any operating system including Windows, Macs, Linux, and Solaris. Here’s a link to our original VirtualBox tutorial to get you started. We suggest allocating 1GB of RAM and at least a 20GB disk image to your virtual machine for best performance.

2. Install a Linux Flavor for Incredible PBX for Asterisk-GUI

To be clear, we plan to support many Linux flavors other than RedHat. But Rome wasn’t built in a day so hang in there. We’re flippin’ burgers as fast as we can. For today, you’ll need a 64-bit version of CentOS or Scientific Linux 6.5/6.6. On some platforms, you install 6.5. After the initial update and upgrade steps, you’ll end up with 6.6. There are many flavors of CentOS and Scientific Linux. For Incredible PBX, a minimal install is all you need.

With dedicated hardware, begin by downloading the 64-bit CentOS 6.6 minimal ISO. Boot your server with the ISO, and begin the install. Here are the simplest installation steps:

Choose Language and Click Continue
Click: Install Destination (do not change anything!)
Click: Done
Click: Network & Hostname
Click: ON
Click: Done
Click: Begin Installation
Click: Root Password: password, password, Click Done twice
Wait for Minimal Software Install and Setup to finish
Click: Reboot

With most cloud-based providers, you simply choose the CentOS 6.5 platform in creating your initial image. 512MB of RAM is plenty so long as you have a swap file. Within a minute or two, you’re ready to boot up the server.

For VirtualBox, download the Scientific Linux 6.6 minimal install .ova image from SourceForge. Then double-click on the image to load it into VirtualBox. Enable Audio and configure Network with Bridge Adapter in Settings. Then start the virtual machine. Default password for root is password.

With VirtualBox, you can skip this step. For everyone else, log into your server as root and issue the following commands to put the basic pieces in place and to reconfigure your Ethernet port as eth0. On some platforms, some of the commands may generate errors. Don’t worry about it! Just make a note of your IP address so you can log back in with SSH from a desktop computer to begin the Incredible PBX install.

For CentOS/Scientific Linux 6.5 minimal install:

setenforce 0
yum -y upgrade
yum -y install net-tools nano wget
ifconfig
sed -i 's|quiet|quiet net.ifnames=0 biosdevdame=0|' /etc/default/grub
grub2-mkconfig -o /boot/grub2/grub.cfg
wget http://incrediblepbx.com/update-kernel-devel
chmod +x update-kernel-devel
./update-kernel-devel
reboot

For CentOS/Scientific Linux 6.6 minimal install:

setenforce 0
yum -y upgrade
yum -y install net-tools nano wget
ifconfig
reboot

3. Install GIT-R-Done Edition of Incredible PBX for Asterisk-GUI

cd /root
yum -y install wget
wget http://incrediblepbx.com/incrediblepbx11gui-git.tar.gz
tar zxvf incrediblepbx11gui-git.tar.gz
#./create-swapfile-DO  #add this step for Digital Ocean droplets
rm -f incrediblepbx11gui-git.tar.gz
sed -i 's|pbxinaflash.com|incrediblepbx.com|' IncrediblePBX11-GUI-git.sh
./IncrediblePBX11-GUI-git.sh
./IncrediblePBX11-GUI-git.sh

4. Install Incredible Fax for Asterisk-GUI (optional)

Administrators have been trying to stomp out faxing for at least two decades. Here’s a hint. It ain’t gonna happen. So go with the flow and add Gotcha-Free Faxing to your server. It’ll be there when you need it. And sooner or later, you’ll need it. This install script is simple enough for any monkey to complete. Run the script and enter the email address for delivery of your faxes. Then, if you’re in the U.S. or Canada, press the Enter key to accept every default entry during the HylaFax and AvantFax installation steps. For other countries, read the prompts and answer accordingly. When the installation finishes, reboot your server to bring faxing on line. Be sure to change your AvantFax admin password. By default, it is password. You can use the script included in the /root folder: avantfax-pw-change. REMINDER: Don’t forget to reboot your server!

cd /root
./incrediblefax11-GUI.sh
./avantfax-pw-change
reboot

Troubleshooting: If your IAXmodems don’t display with a green IDLE notation in the AvantFax GUI, you may need to restart them once more. After a second reboot, all should be well. The restart command is /root/iaxmodem-restart.

5. Initial Configuration of Incredible PBX for Asterisk-GUI

Incredible PBX is installed with the preconfigured IPtables Linux firewall already in place. It implements WhiteList Security to limit server access to connected LANs, your server’s IP address, your desktop computer’s IP address, and a few of our favorite SIP providers. You can add additional entries to this WhiteList whenever you like using the add-ip and add-fqdn tools in /root. There’s also an Apache security layer for our web applications. And, of course, Asterisk-GUI has its own security methodology using Asterisk’s manager.conf. Finally, we randomize extension and DISA passwords as part of the initial install process. Out of the starting gate, you won’t find a more secure VoIP server implementation anywhere. After all, it’s your phone bill.

Even with all of these layers of security, here are 10 Quick Steps to better safeguard your server. You only do this once, but failing to do it may lead to security issues you don’t want to have to deal with down the road. So DO IT NOW!

First, log into your server as root with your root password and do the following:

Make your root password very secure: passwd
Set your correct time zone: ./timezone-setup
Create admin password for web apps: htpasswd -b /etc/pbx/wwwpasswd admin newpassword
Make a copy of your other passwords: cat passwords.FAQ
Make a copy of your Knock codes: cat knock.FAQ
Decipher IP address and other info about your server: status

Second, log into your server as admin using a web browser pointed to your server’s IP address:

Click USERS tab in Incredible PBX GUI
Click Asterisk-GUI Administration
Log in as user: admin with password: password
Immediately change your admin password and login again

Log in to Asterisk-GUI again with your new password. Expand the options available in the GUI:

Options -> Advanced Options -> Show Advanced Options

Last but not least, Incredible PBX includes an automatic update utility which downloads important updates whenever you log into your server as root. We recommend you log in once a week to keep your server current. Now would be a good time to log out and back into your server at the Linux command line to bring your server up to current specs.

6. Configure Trunks with Incredible PBX for Asterisk-GUI

Now for the fun part. If this is your first VoIP adventure, be advised that this ain’t your grandma’s phone system. You need not and should not put all your eggs in one basket when it comes to telephone providers. In order to connect to Plain Old Telephones, you still need at least one provider. But there is nothing wrong with having several. And a provider that handles an outbound call (termination) need not be the same one that handles an incoming call (origination) and provides your phone number (DID). We cannot recommend Vitelity highly enough, and it’s not just because they have financially supported our projects for almost a decade. They’re as good as VoIP providers get, and we use lots of them. If you’re lucky enough to live in the U.S., you’d be crazy not to set up a Google Voice account. It’s free as are all phone calls to anywhere in the U.S. and Canada. The remaining preconfigured providers included in Incredible PBX for Asterisk-GUI are equally good, and we’ve used and continue to use almost all of them. So pick a few and sign up. You only pay for the calls you make with each provider so you have little to lose by choosing several. The PIAF Forum includes dozens of recommendations on VoIP providers if you want additional information.

With the preconfigured trunks in Incredible PBX for Asterisk-GUI, all you need are your credentials for each provider and the FQDN of their server. Log into Asterisk-GUI Administration as admin using a browser. From the System Status screen, click Incredible PBX Apps. Click on each provider you have chosen and fill in the blanks with your credentials. When you’ve saved all of your settings, log into your server as root via SSH and type: service asterisk restart or asterisk-restart. You can also issue the command in the Asterisk-GUI by choosing the Asterisk CLI tab² in the left column. Doesn’t get any simpler!

Update: It should be noted that Incredible PBX for Asterisk-GUI also supports Anveo Direct trunks; however, they are configured differently because of the way Anveo handles the calls. You’ll need the PIN provided by Anveo to set up your trunk, and Anveo supports CallerID spoofing so you can enter any CallerID number for the trunk that you are authorized to use. You’ll find the Anveo Direct setup link in the Incredible PBX Apps tab. To route an outgoing call through Anveo trunk, dial 2 + any desired 10-digit number.

Here is the complete list of dialing prefixes and the trunks to which they are associated:

• 1 – Google Voice
• 2 – Anveo Direct
• 3 – Future Nine
• 4 – CallCentric
• 5 – DIDlogic
• 6 – IPcomms
• 7 – Les.net
• 8 – Vitelity
• 9 – VoIP.ms

For free iNUM calling worldwide, the following dialing prefixes are supported in conjunction with the last seven digits of any destination iNUM DID. Free iNUM DIDs for your own PBX are available from both of these providers as well.

• 0XXXXXXX – CallCentric
• 90XXXXXXX – VoIP.ms

Finally, in addition to the native Asterisk motif implementation of Google Voice (covered below) which uses insecure authentication with Google Voice, we also support the new Simonics SIP gateway to Google Voice using OAUTH authentication. Just click this link for the installation script and tutorial.

7. Configure a Softphone with Incredible PBX for Asterisk-GUI

We’re in the home stretch now. You can connect virtually any kind of telephone to your new Gotcha-Free PBX. Plain Old Phones require an analog telephone adapter (ATA) which can be a separate board in your computer from a company such as Digium. Or it can be a standalone SIP device such as ObiHai’s OBi100 or OBi110 (if you have a phone line from Ma Bell to hook up as well). SIP phones can be connected directly so long as they have an IP address. These could be hardware devices or software devices such as the YateClient softphone. We’ll start with a free one today so you can begin making calls. You can find dozens of recommendations for hardware-based SIP phones both on Nerd Vittles and the PIAF Forum when you’re ready to get serious about VoIP telephony.

We recommend YateClient which is free. Download it from here. Run YateClient once you’ve installed it and enter the credentials for the 6002 extension on Incredible PBX. You’ll need the IP address of your server plus your extension 6002 password. Choose Users -> 6002 and write down your SIP/IAX Password. You can also find it in /root/passwords.FAQ. Fill in the blanks using the IP address of your server, 6002 for your account name, and whatever password is assigned to the extension. Click OK to save your entries.

Once you are registered to extension 6002, close the Account window. Then click on YATE’s Telephony Tab and place some test calls to the numerous apps that are preconfigured on Incredible PBX. Dial a few of these to get started:

7001 - IVR Demo
123 - Reminders
947 - Weather by ZIP Code
951 - Yahoo News
*61 - Time of Day
TODAY - Today in History


If you are a Mac user, another great no-frills softphone is Telephone. Just download and install it from the Mac App Store.

Configuring Google Voice

If you want to use Google Voice, you’ll need a dedicated Google Voice account to support Incredible PBX. The more obscure the username (with some embedded numbers), the better off you will be. This will keep folks from bombarding you with unsolicited Gtalk chat messages, and who knows what nefarious scheme will be discovered using Google messaging six months from now. So keep this account a secret!

IMPORTANT: Be sure to enable the Google Chat option as one of your phone destinations in Settings, Voice Setting, Phones. That’s the destination we need for The Incredible PBX to work its magic! Otherwise, all inbound and outbound calls will fail.

If you have difficulty finding the Google Chat option after setting up a new Google Voice account, follow this tutorial.

Once you’ve created your Gmail and Google Voice accounts, go to Google Voice Settings and click on the Calls tab. Make sure your settings match these:

• Call Screening – OFF
• Call Presentation – OFF
• Caller ID (In) – Display Caller’s Number
• Caller ID (Out) – Don’t Change Anything
• Do Not Disturb – OFF
• Call Options (Enable Recording) – OFF
• Global Spam Filtering – ON

Click Save Changes once you’ve adjusted your settings. Under the Voicemail tab, plug in your email address so you get notified of new voicemails. Down the road, receipt of a Google Voice voicemail will be a big hint that something has come unglued on your PBX.

One final word of caution is in order regardless of your choice of providers: Do NOT use special characters in any provider passwords, or nothing will work!

Now you’re ready to configure your Google Voice account in Incredible PBX. You can do it from within Asterisk-GUI by choosing Google Voice within the Incredible PBX Apps tab. Once you entered your credentials, don’t forget to restart Asterisk, or Google Voice calls will fail. If you still have trouble placing or receiving calls, try these tips.

OK, Smarty Pants: Show Me the Beef!

We know what some of you are thinking. "What does a fast food worker really know about VoIP and Gotcha-Free PBXs?? Before I waste a bunch of time on this, show me the beef!" Fair enough. Sit by your phone and click the Call Me icon below. Type in a fake name and your real phone number. Click the Connect button, answer your phone when it rings, and press 1. You’ll be connected to the Incredible PBX IVR for Asterisk-GUI. Pick an option from the menu of choices and take the Incredible PBX apps for a spin on our dime… actually it’s Google’s dime. Everything you see and hear is part of what you get with Incredible PBX for Asterisk-GUI including the ability to set up your own click-to-dial web interface exactly like this one. The demo just happens to be running on our Mac desktop instead of yours. So… what are you waiting for? Click away and try Incredible PBX for yourself. And, by the way, nobody besides the NSA and Google will be monitoring your call. 😉

Nerd Vittles Demo IVR Options
1 – Call by Name (say “Delta Airlines” or “American Airlines” to try it out)
2 – MeetMe Conference (password is 1234)
3 – Wolfram Alpha (say “What planes are overhead?”)
4 – Lenny (The Telemarketer’s Worst Nightmare)
5 – Today’s News Headlines
6 – Weather Forecast (say the city and state, province, or country)
7 – Today in History
8 – Speak to a Real Person (or maybe just voicemail if we’re out)

Homework Assignment: Mastering the Asterisk-GUI

We’ll have more to say about the Incredible PBX applications next week. In the meantime, you have some homework. You need to learn all about Asterisk-GUI and how to make the best use of its powerful feature set. Here’s one word of warning. We mentioned that Incredible PBX was a hybrid system that combines some customized settings with the standard Asterisk-GUI interface. Before modifying existing settings for the default trunks, extensions, and default routes, take a look at the credentials* files in /etc/asterisk. If you modify any of these trunk entries or the Outgoing or Incoming Call Rules in Asterisk-GUI, you may break the Incredible PBX setup. So steer clear of that minefield until you know what you’re doing. Adding new extensions and additional trunks is perfectly fine and will not break anything.

Rather than reinvent the wheel, we’ll point you to some excellent tutorials that already have been written. Start with Chapter 3 of Digium’s Asterisk Appliance™ Administrator Manual. Next, review Chapter 11 of The Asterisk Book (Second Edition). Finally, take a look at a couple of the tutorials that have been written by other companies that incorporated Asterisk-GUI into their hardware products, e.g. Yeastar’s MyPBX SOHO User Manual and Grandstream’s UCM6100 User Manual. Then check back with us next week for Chapter 2.

In the meantime, if you have questions, join the PBX in a Flash Forums and take advantage of our awesome collection of gurus. There’s an expert available on virtually any topic, and the price is right. As with Incredible PBX, it’s absolutely free.

We also are quickly building a collection of tutorials tailored specifically for Incredible PBX for Asterisk-GUI:

5. Configure a Softphone with Incredible PBX for Asterisk-GUI

We’re in the home stretch now. You can connect virtually any kind of telephone to your new Gotcha-Free PBX. Plain Old Phones require an analog telephone adapter (ATA). Because your server is actually in the RentPBX Cloud, a standalone SIP device is required. Good choices are ObiHai’s OBi100 or OBi110 (if you have a phone line from Ma Bell to hook up as well). SIP phones can be connected directly so long as they have an IP address. These could be hardware devices or software devices such as the YateClient softphone. We’ll start with a free one today so you can begin making calls. You can find dozens of recommendations for hardware-based SIP phones both on Nerd Vittles and the PIAF Forum when you’re ready to get serious about VoIP telephony. Don’t forget to WhiteList the IP address of each SIP phone you wish to connect using /root/add-ip or /root/add-fqdn.

We recommend the YateClient softphone which is free. Download it from here. Run YateClient once you’ve installed it and enter the credentials for the 6002 extension on Incredible PBX. You’ll need the IP address of your server plus your extension 6002 password. Choose Users -> 6002 and write down your SIP/IAX Password. You can also find it in /root/passwords.FAQ. Fill in the blanks using the IP address of your server, 6002 for your account name, and whatever password is assigned to the extension. Click OK to save your entries.

Once you are registered to extension 6002, close the Account window. Then click on YATE’s Telephony Tab and place some test calls to the numerous apps that are preconfigured on Incredible PBX. Dial a few of these to get started:

951 - Yahoo News
*61 - Time of Day

If you are a Mac user, another great no-frills softphone is Telephone. Just download and install it from the Mac App Store.

Configuring Google Voice

If you want to use Google Voice, you’ll need a dedicated Google Voice account to support Incredible PBX. The more obscure the username (with some embedded numbers), the better off you will be. This will keep folks from bombarding you with unsolicited Gtalk chat messages, and who knows what nefarious scheme will be discovered using Google messaging six months from now. So keep this account a secret!

IMPORTANT: Do NOT under any circumstances take Google’s bait to switch from Google Chat to Hangouts, or you will forever lose the ability to use Google Chat with Incredible PBX. Also be sure to enable the Google Chat option as one of your phone destinations in Settings, Voice Setting, Phones. That’s the destination we need for The Incredible PBX to work its magic! Otherwise, all inbound and outbound calls will fail. Thus far, Google has apparently had a change of heart on discontinuing Google Chat support so it’s enabled by default in all new Google Voice accounts. Nothing free lasts forever so make some alternative arrangements before disaster strikes!

Once you’ve created a Gmail and Google Voice account, go to Google Voice Settings and click on the Calls tab. Make sure your settings match these:

• Call Screening – OFF
• Call Presentation – OFF
• Caller ID (In) – Display Caller’s Number
• Caller ID (Out) – Don’t Change Anything
• Do Not Disturb – OFF
• Call Options (Enable Recording) – OFF
• Global Spam Filtering – ON

Click Save Changes once you’ve adjusted your settings. Under the Voicemail tab, plug in your email address so you get notified of new voicemails. Down the road, receipt of a Google Voice voicemail will be a big hint that something has come unglued on your PBX.

One final word of caution is in order regardless of your choice of providers: Do NOT use special characters in any provider passwords, or nothing will work!

Now you’re ready to configure your Google Voice account in Incredible PBX. You can do it from within Asterisk-GUI by choosing Google Voice within the Incredible PBX Apps tab. Once you’ve entered your credentials, don’t forget to restart Asterisk, or Google Voice calls will fail. If you still have trouble placing or receiving calls, follow these tips.

Homework Assignment: Mastering the Incredible Apps and Asterisk-GUI

Just Released: The Gotcha-Free Incredible PBX Application User’s Guide

Your next stop should be a careful reading of the new Incredible PBX Application User’s Guide. It documents the 31 apps for Asterisk that are included with your new PBX. You also need to learn all you can about Asterisk-GUI and how to make the best use of its powerful feature set. Here’s one word of warning. We mentioned that Incredible PBX was a hybrid system that combines some customized settings with the standard Asterisk-GUI interface. Before modifying existing settings for the default trunks, extensions, and default routes, take a look at the credentials* files in /etc/asterisk. If you modify any of these trunk entries or the Outgoing or Incoming Call Rules in Asterisk-GUI, you may break the Incredible PBX setup. So steer clear of that minefield until you know what you’re doing. Adding new extensions and additional trunks is perfectly fine and will not break anything.

Rather than reinvent the wheel, we’ll point you to some excellent tutorials that already have been written. Start with Chapter 3 of Digium’s Asterisk Appliance™ Administrator Manual. Next, review Chapter 11 of The Asterisk Book (Second Edition). Finally, take a look at a couple of the tutorials that have been written by other companies that incorporated Asterisk-GUI into their hardware products, e.g. Yeastar’s MyPBX SOHO User Manual and Grandstream’s UCM6100 User Manual.

In the meantime, if you have questions, join the PBX in a Flash Forums and take advantage of our awesome collection of gurus. There’s an expert available on virtually any topic, and the price is right. As with Incredible PBX, it’s absolutely free.

We also are quickly building a collection of tutorials tailored specifically for Incredible PBX for Asterisk-GUI:

OK. The Raspberry Pi 2 may not quite rival the Raspberry Pi supercomputer built at Boise State, but it’s getting closer. The supercomputer that included 32 Raspberry Pi’s a year ago can now be built with about 5 Raspberry Pi 2’s. While the footprint may look the same as the $35 Raspberry Pi that you knew and loved two years ago, the RasPi² sports a 900MHz ARMv7 quad core processor with a full gig of RAM under the hood. And even though the Raspberry Pi 2 may be camera-shy, there’s a good reason. It’s a screamer! Early testing indicates a six-fold increase in performance even though it still looks much the same. What hasn’t changed is the price. It’s still $35 in the U.S. if you can find one. We couldn’t wait so we headed to the Pimoroni Shop in the U.K. to order ours with a Pibow case. Shipped within hours, and we got it in 2 days!

Do we have a Valentine’s Treat for you! Today we’re pleased to introduce the all-new Raspberry Pi edition of Incredible PBX for Asterisk-GUI featuring the just-released Raspberry Pi 2 and the just-released Asterisk® 11.16. And, not to worry, if you ever get tired of running your own PBX (and we don’t think you will), Micro$oft announced last week that you’re going to get a free version of Windows 10 for the Raspberry Pi 2 later this year.

Last week we released a tutorial covering all of the new Gotcha Free PBX applications, and that guide applies to today’s Raspberry Pi 2 release as well. That’s the beauty of the new Incredible PBX modular design. And, speaking of design, we don’t build Incredible PBX servers with an included operating system any longer so we’ll walk you through getting the Raspberry Pi 2 squared away with the latest and greatest version of Raspbian before we actually install Incredible PBX.

Getting Started with Incredible PBX for Asterisk-GUI (RasPi 2 Edition)

Here’s a quick overview of the installation and setup process for Incredible PBX for Asterisk-GUI:

1. Install Linux for Raspberry Pi 2 – Install Raspbian 7 Platform
2. Configure Raspbian 7 – Optimize Raspbian 7 for Incredible PBX
3. Download and Install Incredible PBX for Asterisk-GUI
4. Install Incredible Fax for Asterisk-GUI (optional)
5. Set Up Passwords for Incredible PBX for Asterisk-GUI
6. Configure Trunks with Incredible PBX for Asterisk-GUI
7. Connect a Softphone to Incredible PBX for Asterisk-GUI

1. Install Raspbian 7 Platform for Raspberry Pi 2

For those with Raspberry Pi experience, this is the same drill you’ve performed a dozen times before. For newbies, here’s the procedure. You’ll need a microSD card of at least 8GB, and we strongly recommend a 16GB or 32GB Type 10 card for Incredible PBX. We’ve tested both the SanDisk and Transcend cards, and they work great.

Begin by downloading the very latest RASPBIAN image from RaspberryPi.org to your desktop. After you’ve unzipped the image, you need to get it moved to your microSD card. RaspberryPi.org has excellent tutorials that will walk you through the process using a Linux, Mac, or Windows desktop platform. Don’t forget to unmount the card before removing it!

Once you have your microSD card ready to go, plug it into the slot on the back of the Raspberry Pi 2 and then plug in the power cord. On your attached monitor, you can follow the boot up process. When the login prompt appears, log in as user pi with the password raspberry.

2. Optimizing Raspbian 7 for Incredible PBX for Asterisk-GUI

The first time you boot up your Raspberry Pi 2 with Raspbian 7, it will run the raspi-config script. This allows you to make a number of changes to your Raspberry Pi environment to maximize performance. Let’s take advantage of it.

Option 1. Expand the File System to fill your SD card. Otherwise, there’s insufficient disk space to complete the install.

Option 3. Enable Boot to Desktop (top selection). No Linux GUI please!

Option 8. Change your Hostname under A2 to incrediblepi2.

Tab to the Finish option and press ENTER. Then choose Reboot and YES.

After the reboot, log back in as pi:raspberry and set a very secure root password: sudo passwd root. Decipher your IP address so that you can log in as root via SSH: ifconfig.

We recommend completing the install by logging in as root using a desktop computer via SSH or Putty (for Windows). This gives you the ability to scroll back up and find errors if something happens to come unglued during the install process.

3. Install Incredible PBX on Your Raspberry Pi 2

Adding Incredible PBX to the Raspberry Pi 2 is easy. To restate the obvious, your server needs a reliable Internet connection to proceed. Using SSH (or Putty on a Windows machine), log into your Raspberry Pi 2 as root at the IP address you deciphered in the ifconfig step at the end of the Raspbian install procedure above.

IMPORTANT: Before you begin the Incredible PBX install, expand your console window to at least 80×27, or the Asterisk compilation step may fail. If you’re in doubt about the window dimensions, just maximize the window to full-screen during the install process.

Now let’s begin the Incredible PBX install. After logging in as root, issue the following commands. The install takes less than an hour and runs unattended so there’s no need to watch unless you’re curious how sausage is made. Remember, we compile all of the major components for Incredible PBX as part of the build process. And you can review the open source GPL2 script to see how it’s done if you have an interest or wish to embellish. It’s Gotcha-Free code so go for it and share your discoveries. After all, that’s what open source is all about!

cd /root
wget http://incrediblepbx.com/incrediblepbx11guiPi.tar.gz
tar zxvf incrediblepbx11guiPi.tar.gz
rm -f incrediblepbx11guiPi.tar.gz
./IncrediblePBX11Pi-GUI.sh

4. Install Incredible Fax for Asterisk-GUI (optional)

Administrators have been trying to stomp out faxing for at least two decades. Here’s a hint. It ain’t gonna happen. So go with the flow and add Gotcha-Free Faxing to your server. It’ll be there when you need it. And sooner or later, you’ll need it. This install script is simple enough for any monkey to complete. Run the script and enter the email address for delivery of your faxes. Then, if you’re in the U.S. or Canada, press the Enter key to accept every default entry during the HylaFax and AvantFax installation steps. For other countries, read the prompts and answer accordingly. When the installation finishes, reboot your server to bring faxing on line. Be sure to change your AvantFax admin password by logging in to AvantFax from the Incredible PBX GUI. By default, the admin password is password. You can also use the script included in the /root folder: avantfax-pw-change. REMINDER: Don’t forget to reboot your server!

cd /root
./incrediblefax11-GUI.sh

Outgoing faxes using standard document attachments can be created using the AvantFax GUI. The faxes will be sent out using your default outbound dial rules. For example, a 10-digit number will be sent using the default Google Voice trunk unless you haven’t configured it. Then the next configured trunk will be used. You can add a dial prefix in sending a fax with AvantFax to force the call out a particular trunk.

Incoming faxes will be delivered to the email address you specified when installing Incredible Fax; however, incoming faxes will be ignored until you configure a destination DID to accept the faxes. In the /etc/asterisk directory, edit extensions.conf. As noted, a dedicated DID is required to support incoming faxes! Find the desired incoming fax context which will be of the form: DID_TRUNKNAME_default, e.g. DID_GoogleVoice_default. Toward the end of the context, there will be several destination options for incoming calls to this DID. It looks like this:

;exten = _.,n,Gosub(macro-dumpvars,s,1())  ; in case you ever want to look at all of the Asterisk variables on the CLI
;exten = _.,n,Goto(default,6001,1)         ; routes incoming call to extension 6001
;exten = _.,n,Goto(ringroups-custom-1,s,1) ; routes incoming call to Ring Group #1
;exten = _.,n,Goto(voicemenu-custom-2,s,1) ; routes incoming call to Nerd Vittles Demo IVR
 exten = _.,n,Goto(voicemenu-custom-1,s,1)  ; routes incoming call to Stealth AutoAttendant and then to Ring Group #1

Comment out the destination entry that is not already commented out. Then add the following line just below that entry:

exten = _.,n,Goto(ext-fax,in_fax,1)

Now save the file and reload your Asterisk dialplan: asterisk-reload.

5. Initial Configuration of Incredible PBX for Asterisk-GUI

Incredible PBX is installed with the preconfigured IPtables Linux firewall already in place. It implements WhiteList Security to limit server access to connected LANs, your server’s IP address, your desktop computer’s IP address, and a few of our favorite SIP providers. You can add additional entries to this WhiteList whenever you like using the add-ip and add-fqdn tools in /root. There’s also an Apache security layer for our web applications. And, of course, Asterisk-GUI has its own security methodology using Asterisk’s manager.conf. Finally, we randomize extension and DISA passwords as part of the initial install process. Out of the starting gate, you won’t find a more secure VoIP server implementation anywhere. After all, it’s your phone bill.

Even with all of these layers of security, here are 10 Quick Steps to better safeguard your server. You only do this once, but failing to do it may lead to security issues you don’t want to have to deal with down the road. So DO IT NOW!

First, log into your server as root with your root password and do the following:

Make your root password very secure: passwd
Set your correct time zone: ./timezone-setup
Restart Asterisk: asterisk-restart
Create admin password for web apps: htpasswd -b /etc/pbx/wwwpasswd admin newpassword
Make a copy of your other passwords: cat passwords.FAQ
Make a copy of your Knock codes: cat knock.FAQ
Decipher IP address and other info about your server: status

Second, log into your server as admin using a web browser pointed to your server’s IP address:

Click USERS tab in Incredible PBX GUI
Click Asterisk-GUI Administration
Log in as user: admin with password: password
Immediately change your admin password and login again

Log in to Asterisk-GUI again with your new password. Expand the options available in the GUI:

Options -> Advanced Options -> Show Advanced Options

Last but not least, Incredible PBX includes an automatic update utility which downloads important updates whenever you log into your server as root. We recommend you log in once a week to keep your server current. Now would be a good time to log out and back into your server at the Linux command line to bring your Raspberry Pi 2 up to current specs.

6. Configure Trunks with Incredible PBX for Asterisk-GUI

Now for the fun part. If this is your first VoIP adventure, be advised that this ain’t your grandma’s phone system. You need not and should not put all your eggs in one basket when it comes to telephone providers. In order to connect to Plain Old Telephones, you still need at least one provider. But there is nothing wrong with having several. And a provider that handles an outbound call (termination) need not be the same one that handles an incoming call (origination) and provides your phone number (DID). We cannot recommend Vitelity highly enough, and it’s not just because they have financially supported our projects for almost a decade. They’re as good as VoIP providers get, and we use lots of them. If you’re lucky enough to live in the U.S., you’d be crazy not to set up a Google Voice account. It’s free as are all phone calls to anywhere in the U.S. and Canada. The remaining preconfigured providers included in Incredible PBX for Asterisk-GUI are equally good, and we’ve used and continue to use almost all of them. So pick a few and sign up. You only pay for the calls you make with each provider so you have little to lose by choosing several. The PIAF Forum includes dozens of recommendations on VoIP providers if you want additional information.

With the preconfigured trunks in Incredible PBX for Asterisk-GUI, all you need are your credentials for each provider and the FQDN of their server. Log into Asterisk-GUI Administration as admin using a browser. From the System Status screen, click Incredible PBX Apps. Click on each provider you have chosen and fill in the blanks with your credentials. When you’ve saved all of your settings, log into your server as root via SSH and type: service asterisk restart or asterisk-restart. You can also issue the command in the Asterisk-GUI by choosing the Asterisk CLI tab² in the left column. Doesn’t get any simpler!

Update: It should be noted that Incredible PBX for Asterisk-GUI also supports Anveo Direct trunks; however, they are configured differently because of the way Anveo handles the calls. You’ll need the PIN provided by Anveo to set up your trunk, and Anveo supports CallerID spoofing so you can enter any CallerID number for the trunk that you are authorized to use. You’ll find the Anveo Direct setup link in the Incredible PBX Apps tab. To route an outgoing call through Anveo trunk, dial 2 + any desired 10-digit number.

Here is the complete list of dialing prefixes and the trunks to which they are associated:

• 1 – Google Voice
• 2 – Anveo Direct
• 3 – Future Nine
• 4 – CallCentric
• 5 – DIDlogic
• 6 – IPcomms
• 7 – Les.net
• 8 – Vitelity
• 9 – VoIP.ms

For free iNUM calling worldwide, the following dialing prefixes are supported in conjunction with the last seven digits of any destination iNUM DID. Free iNUM DIDs for your own PBX are available from both of these providers as well.

• 0XXXXXXX – CallCentric
• 90XXXXXXX – VoIP.ms

7. Configure a Softphone with Incredible PBX for Asterisk-GUI

We’re in the home stretch now. You can connect virtually any kind of telephone to your new Gotcha-Free PBX. Plain Old Phones require an analog telephone adapter (ATA) which can be a separate board in your computer from a company such as Digium. Or it can be a standalone SIP device such as ObiHai’s OBi100 or OBi110 (if you have a phone line from Ma Bell to hook up as well). SIP phones can be connected directly so long as they have an IP address. These could be hardware devices or software devices such as the YateClient softphone. We’ll start with a free one today so you can begin making calls. You can find dozens of recommendations for hardware-based SIP phones both on Nerd Vittles and the PIAF Forum when you’re ready to get serious about VoIP telephony.

We recommend YateClient which is free. Download it from here. Run YateClient once you’ve installed it and enter the credentials for the 6002 extension on Incredible PBX. You’ll need the IP address of your server plus your extension 6002 password. Choose Users -> 6002 and write down your SIP/IAX Password. You can also find it in /root/passwords.FAQ. Fill in the blanks using the IP address of your server, 6002 for your account name, and whatever password is assigned to the extension. Click OK to save your entries.

Once you are registered to extension 6002, close the Account window. Then click on YATE’s Telephony Tab and place some test calls to the numerous apps that are preconfigured on Incredible PBX. Dial a few of these to get started:

7001 - IVR Demo
123 - Reminders

951 - Yahoo News
*61 - Time of Day

If you are a Mac user, another great no-frills softphone is Telephone. Just download and install it from the Mac App Store.

Configuring Google Voice

If you want to use Google Voice, you’ll need a dedicated Google Voice account to support Incredible PBX. The more obscure the username (with some embedded numbers), the better off you will be. This will keep folks from bombarding you with unsolicited Gtalk chat messages, and who knows what nefarious scheme will be discovered using Google messaging six months from now. So keep this account a secret!

IMPORTANT: Do NOT under any circumstances take Google’s bait to switch from Google Chat to Hangouts, or you will forever lose the ability to use Google Chat with Incredible PBX. Also be sure to enable the Google Chat option as one of your phone destinations in Settings, Voice Setting, Phones. That’s the destination we need for The Incredible PBX to work its magic! Otherwise, all inbound and outbound calls will fail. Good News! You’re in luck. Google has apparently had a change of heart on discontinuing Google Chat support so it’s enabled by default in all new Google Voice accounts. Once you’ve created a Gmail and Google Voice account, go to Google Voice Settings and click on the Calls tab. Make sure your settings match these:

• Call Screening – OFF
• Call Presentation – OFF
• Caller ID (In) – Display Caller’s Number
• Caller ID (Out) – Don’t Change Anything
• Do Not Disturb – OFF
• Call Options (Enable Recording) – OFF
• Global Spam Filtering – ON

Click Save Changes once you’ve adjusted your settings. Under the Voicemail tab, plug in your email address so you get notified of new voicemails. Down the road, receipt of a Google Voice voicemail will be a big hint that something has come unglued on your PBX.

One final word of caution is in order regardless of your choice of providers: Do NOT use special characters in any provider passwords, or nothing will work!

Now you’re ready to configure your Google Voice account in Incredible PBX. You can do it from within Asterisk-GUI by choosing Google Voice within the Incredible PBX Apps tab. Once you’ve entered your credentials, don’t forget to restart Asterisk, or Google Voice calls will fail. If you still have trouble placing or receiving calls, try BOTH of these tips.

If you have difficulty finding the Google Chat option after setting up a new Google Voice account, follow this tutorial.

NOTE: There are all sorts of rumors circulating again that the Google Voice free ride may be coming to a close. We’ve heard this song before, but who knows?? Whether true or not, you are well advised to not rely solely on Google Voice for your phone calls. That’s the real beauty of a PBX. So take advantage of it!

Homework Assignment: Mastering the Asterisk-GUI

Now would be a good time to explore the Incredible PBX applications. Continue reading there. After you’ve played with the preconfigured features, it’s time to roll up your sleeves and learn about Asterisk-GUI and its powerful feature set. Here’s one word of warning. We mentioned that Incredible PBX was a hybrid system that combines some customized settings with the standard Asterisk-GUI interface. Before modifying existing settings for the default trunks, extensions, and default routes, take a look at the credentials* files in /etc/asterisk. If you modify any of these trunk entries or the Outgoing or Incoming Call Rules in Asterisk-GUI, you may break the Incredible PBX setup. So steer clear of that minefield until you know what you’re doing. Adding new extensions and additional trunks is perfectly fine and will not break anything.

Rather than reinvent the wheel, we’ll point you to some excellent tutorials that already exist. Start with Chapter 3 of Digium’s Asterisk Appliance™ Administrator Manual. Next, review Chapter 11 of The Asterisk Book (Second Edition). Finally, take a look at a couple of the tutorials that have been written by other companies that incorporated Asterisk-GUI into their hardware products, e.g. Yeastar’s MyPBX SOHO User Manual and Grandstream’s UCM6100 User Manual.

In the meantime, if you have questions, join the PBX in a Flash Forums and take advantage of our awesome collection of gurus. There’s an expert available on virtually any topic, and the price is right. As with Incredible PBX, it’s absolutely free.

Some Recent Nerd Vittles Articles of Interest…

2. If, for some reason, the Asterisk CLI tab does not appear on your server, click Options -> Advanced Options -> Show Advanced Options. [↩]

WARNING: This version is no longer secure and use of it is strongly discouraged.

Remember the old adage that Rome wasn’t built in a day? Well, thanks to Mark Spencer and his team of incredibly talented programmers coupled with the modular design of Asterisk® and Asterisk-GUI, times have changed. It took about a month to put the CentOS version of Incredible PBX™ for Asterisk-GUI together. Today’s Ubuntu® version was created in one day! That should tell you all you need to know about the design. Better yet, with a cloud platform such as Digital Ocean,¹ you can deploy Incredible PBX for Asterisk-GUI in about 15 minutes. Add another 5 minutes to configure some trunks and plug in a couple phones, and you’ll have a Gotcha-Free PBX in less time than it takes to wolf down a Waffle House breakfast.

We try to make new product tutorials stand on their own so you don’t have to jump around to figure everything out. But, if you’re generally familiar with the process of installing Incredible PBX, then this will be a walk in the park for you. Last week we released a tutorial covering all of the new Gotcha Free PBX applications, and that guide applies to today’s Ubuntu release as well. The names of a few components are different (such as the Incredible Fax installer), but functionally everything works in exactly the same way as the CentOS platform release. After all, that’s the beauty of the modular design.

Target Audience: Home or SOHO/SBO in need of a turnkey, Gotcha-Free PBX Default Configuration: Asterisk 11 with enhanced Asterisk-GUI, Kennonsoft GUI, and NANPA dialplan Platform: Ubuntu 14.04 (32/64-bit) running on Dedicated Server, Cloud-Based Server, or Virtual Machine Minimum Memory: 512MB Recommended Disk: 20GB+ Default Trunks: Google Voice, CallCentric, DIDlogic, Future-Nine, IPcomms, Les.net, Vitelity, VoIP.ms2 Feature Set: Fax, SMS messaging, VPN, Reminders, ConfBridge Conferencing, AsteriDex, Voicemail, Email, IVR, News, Weather, Voice Dialer, Wolfram Alpha, Today in History, TM3 Firewall WhiteList, Speed Dialer, iNUM and SIP URI (free) worldwide calling, OpenCNAM CallerID lookups, DISA, Call Forwarding, CSV CDRs Administrator Utilities: Incredible Backup/Restore, Automatic Updater, Asterisk Upgrader, phpMyAdmin, Timezone Config, Plug-and-Play Trunk Configurator, WebMin, External IP Setup, Firewall WhiteList Tools

Getting Started with Incredible PBX for Asterisk-GUI (Ubuntu Edition)

Here’s a quick overview of the installation and setup process for Incredible PBX for Asterisk-GUI:

1. Choose a Hardware Platform – Dedicated PC, Virtual Machine, or Cloud Provider
2. Install a Linux Flavor – Install Ubuntu 14.04 Platform for Incredible PBX
3. Download and Install Incredible PBX for Asterisk-GUI
4. Install Incredible Fax for Asterisk-GUI (optional)
5. Set Up Passwords for Incredible PBX for Asterisk-GUI
6. Configure Trunks with Incredible PBX for Asterisk-GUI
7. Connect a Softphone to Incredible PBX for Asterisk-GUI

1. Choose a Platform for Incredible PBX for Asterisk-GUI

Incredible PBX for Asterisk-GUI works equally well on dedicated hardware, a virtual machine, or a cloud-based server. Just be sure you’ve met the minimum requirements outlined above and that you have a sufficiently robust Internet connection to support 100Kb of download and upload bandwidth for each simultaneous call you wish to handle with your new PBX.

For Dedicated Hardware, we recommend an Atom-based PC of recent vintage with at least a 30GB drive and 4GB of RAM. That will take care of an office with 10-20 extensions and a half dozen or more simultaneous calls if you have the Internet bandwidth to support it.

For Virtual Machine Installs, we recommend Oracle’s VirtualBox platform which runs atop almost any operating system including Windows, Macs, Linux, and Solaris. Here’s a link to our original VirtualBox tutorial to get you started. We suggest allocating 1GB of RAM and at least a 20GB disk image to your virtual machine for best performance.

For Cloud-Based Servers, we recommend RentPBX, one of our financial supporters who also happens to size servers properly and restrict usage solely to VoIP. This avoids performance bottlenecks that cause problems with VoIP calls. If you’re just experimenting, then a 512MB Digital Ocean droplet is a cost-effective option at a cost of less than a penny an hour. In addition to a little referral revenue for Nerd Vittles, the nicest features of Digital Ocean are the availability of preconfigured CentOS images and a platform on which you can install Incredible PBX and be ready to start making calls very, very quickly. If you make a serious mistake during the install or setup, it’s a 30-second task to delete your droplet and create a new one. You’re only out a penny! And reloading Incredible PBX from scratch is never more than a 20-minute task. Remember to run the create-swapfile-DO script included in the Incredible PBX tarball before beginning your install to avoid out-of-memory conditions.

2. Install Ubuntu 14.04 Platform for Incredible PBX

For dedicated hardware installs, download the 32-bit or 64-bit Ubuntu 14.04 “Trusty Tahr” Minimal ISO. Burn it to a CD/DVD or thumb drive and boot your dedicated server from the image. Remember, you’ll be reformatting the drive in your server so pick a machine you don’t need for other purposes.

For virtual machine installs, download the same ISO and specify it as the boot drive for your virtual machine. If you’re using the VirtualBox platform, create a new virtual machine specifying either the 32-bit or 64-bit version of Ubuntu. Allocate 1024MB of RAM (512MB also works fine!) and at least 20GB of disk space using the default hard drive setup in all three steps. In Settings, click System and check Enable I/O APIC and uncheck Hardware Clock in UTC Time. Click Audio and Specify then Enable your sound card. Click Network and Enable Network Adapter for Adapter 1 and choose Bridged Adapter. Finally, in Storage, add the Ubuntu 14.04 mini.iso to your VirtualBox Storage Tree as shown below. Then click OK and start up your new virtual machine.

Here are the steps to get Ubuntu 14.04 set up on dedicated hardware or a virtual machine:
UBUNTU mini.iso install:
Choose language
Choose timezone
Detect keyboard
Hostname: incrediblepbx < continue >
Choose mirror for downloads
Confirm archive mirror
Leave proxy blank unless you need it < continue >
** couple minutes of whirring as initial components are loaded **
New user name: incredible < continue >
Account username: incredible < continue >
Account password: makeitsecure < continue >
Encrypt home directory < no >
Confirm time zone < yes >
Partition disks: Guided - use entire disk and set up LVM
Confirm disk to partition
Write changes to disks and configure LVM
Whole volume? < continue>
Write changes to disks < yes> < -- last chance to preserve your disk drive! ** about 15 minutes of whirring during base system install ** < no touchy anything>
** another 5 minutes of whirring during base software install ** < no touchy anything>
Upgrades? Install security updates automatically
** another 5 minutes of whirring during more software installs ** < no touchy anything>
Software selection: *Basic Ubuntu server (only!)
** another couple minutes of whirring during software installs ** < no touchy anything>
Grub boot loader: < yes>
UTC for system clock: < no>
Installation complete: < continue> after removing installation media
** on VirtualBox, PowerOff after reboot and remove [-] mini.iso from Storage Tree & restart VM
login as user: incredible
** enter user incredible's password **
sudo passwd
** enter incredible password again and then create secure root user password **
su root
** enter root password **
apt-get update
apt-get install ssh -y
sed -i 's|without-password|yes|' /etc/ssh/sshd_config
sed -i 's|yes"|without-password"|' /etc/ssh/sshd_config
sed -i 's|"quiet"|"quiet text"|' /etc/default/grub
update-grub
ifconfig
** write down the IP address of your server from ifconfig results
reboot
** login via SSH to continue **


For Cloud-based servers or virtual machines, typically the provider has done the hard work for you. Just choose either a 32-bit or 64-bit Ubuntu 14.04 platform with at least 512MB of RAM and 20GB of disk storage. If you have to roll your own from an ISO, just follow the steps above.

3. Install Incredible PBX on Your Ubuntu 14.04 Server

Adding Incredible PBX to a running Ubuntu 14.04 server is simple. To restate the obvious, your server needs a reliable Internet connection to proceed. Using SSH (or Putty on a Windows machine), log into your new server as root at the IP address you deciphered in the ifconfig step at the end of the Ubuntu install procedure above.

First, run the update and upgrade procedure for Ubuntu before you begin the install. This is especially important if using a cloud-based Ubuntu 14 server.

apt-get update && apt-get upgrade -y && reboot

WARNING: If you’re using a 512MB droplet at Digital Ocean, be advised that their Ubuntu setup does NOT include a swap file. This may cause serious problems when you run out of RAM. Uncomment ./create-swapfile-DO line below to create a 1GB swap file which will be activated whenever you exceed 90% RAM usage on Digital Ocean.

IMPORTANT: Before you begin the Incredible PBX install, expand your console window to at least 80×27, or the Asterisk compilation step may fail. If you’re in doubt about the window dimensions, just maximize the window to full-screen during the install process.

Now let’s begin the Incredible PBX install. Log back in as root and issue the following commands:

cd /root
wget http://incrediblepbx.com/incrediblepbx11guiU.tar.gz
tar zxvf incrediblepbx11guiU.tar.gz
#./create-swapfile-DO  #add this step for Digital Ocean droplets
rm -f incrediblepbx11guiU.tar.gz
sed -i 's|pbxinaflash.com|incrediblepbx.com|' IncrediblePBX11U-GUI.sh
./IncrediblePBX11U-GUI.sh

4. Install Incredible Fax for Asterisk-GUI (optional)

Administrators have been trying to stomp out faxing for at least two decades. Here’s a hint. It ain’t gonna happen. So go with the flow and add Gotcha-Free Faxing to your server. It’ll be there when you need it. And sooner or later, you’ll need it. This install script is simple enough for any monkey to complete. Run the script and enter the email address for delivery of your faxes. Then, if you’re in the U.S. or Canada, press the Enter key to accept every default entry during the HylaFax and AvantFax installation steps. For other countries, read the prompts and answer accordingly. When the installation finishes, reboot your server to bring faxing on line. Be sure to change your AvantFax admin password. By default, it is password. You can use the script included in the /root folder: avantfax-pw-change. REMINDER: Don’t forget to reboot your server!

cd /root
./incrediblefax11_ubuntu14.sh
./avantfax-pw-change
reboot

5. Initial Configuration of Incredible PBX for Asterisk-GUI

Incredible PBX is installed with the preconfigured IPtables Linux firewall already in place. It implements WhiteList Security to limit server access to connected LANs, your server’s IP address, your desktop computer’s IP address, and a few of our favorite SIP providers. You can add additional entries to this WhiteList whenever you like using the add-ip and add-fqdn tools in /root. There’s also an Apache security layer for our web applications. And, of course, Asterisk-GUI has its own security methodology using Asterisk’s manager.conf. Finally, we randomize extension and DISA passwords as part of the initial install process. Out of the starting gate, you won’t find a more secure VoIP server implementation anywhere. After all, it’s your phone bill.

Even with all of these layers of security, here are 10 Quick Steps to better safeguard your server. You only do this once, but failing to do it may lead to security issues you don’t want to have to deal with down the road. So DO IT NOW!

First, log into your server as root with your root password and do the following:

Make your root password very secure: passwd
Set your correct time zone: ./timezone-setup
Create admin password for web apps: htpasswd -b /etc/pbx/wwwpasswd admin newpassword
Make a copy of your other passwords: cat passwords.FAQ
Make a copy of your Knock codes: cat knock.FAQ
Decipher IP address and other info about your server: status

Second, log into your server as admin using a web browser pointed to your server’s IP address:

Click USERS tab in Incredible PBX GUI
Click Asterisk-GUI Administration
Log in as user: admin with password: password
Immediately change your admin password and login again

Log in to Asterisk-GUI again with your new password. Expand the options available in the GUI:

Options -> Advanced Options -> Show Advanced Options

Last but not least, Incredible PBX includes an automatic update utility which downloads important updates whenever you log into your server as root. We recommend you log in once a week to keep your server current. Now would be a good time to log out and back into your server at the Linux command line to bring your server up to current specs.

6. Configure Trunks with Incredible PBX for Asterisk-GUI

Now for the fun part. If this is your first VoIP adventure, be advised that this ain’t your grandma’s phone system. You need not and should not put all your eggs in one basket when it comes to telephone providers. In order to connect to Plain Old Telephones, you still need at least one provider. But there is nothing wrong with having several. And a provider that handles an outbound call (termination) need not be the same one that handles an incoming call (origination) and provides your phone number (DID). We cannot recommend Vitelity highly enough, and it’s not just because they have financially supported our projects for almost a decade. They’re as good as VoIP providers get, and we use lots of them. If you’re lucky enough to live in the U.S., you’d be crazy not to set up a Google Voice account. It’s free as are all phone calls to anywhere in the U.S. and Canada. The remaining preconfigured providers included in Incredible PBX for Asterisk-GUI are equally good, and we’ve used and continue to use almost all of them. So pick a few and sign up. You only pay for the calls you make with each provider so you have little to lose by choosing several. The PIAF Forum includes dozens of recommendations on VoIP providers if you want additional information.

With the preconfigured trunks in Incredible PBX for Asterisk-GUI, all you need are your credentials for each provider and the FQDN of their server. Log into Asterisk-GUI Administration as admin using a browser. From the System Status screen, click Incredible PBX Apps. Click on each provider you have chosen and fill in the blanks with your credentials. When you’ve saved all of your settings, log into your server as root via SSH and type: service asterisk restart or asterisk-restart. You can also issue the command in the Asterisk-GUI by choosing the Asterisk CLI tab³ in the left column. Doesn’t get any simpler!

Update: It should be noted that Incredible PBX for Asterisk-GUI also supports Anveo Direct trunks; however, they are configured differently because of the way Anveo handles the calls. You’ll need the PIN provided by Anveo to set up your trunk, and Anveo supports CallerID spoofing so you can enter any CallerID number for the trunk that you are authorized to use. You’ll find the Anveo Direct setup link in the Incredible PBX Apps tab. To route an outgoing call through Anveo trunk, dial 2 + any desired 10-digit number.

Here is the complete list of dialing prefixes and the trunks to which they are associated:

• 1 – Google Voice
• 2 – Anveo Direct
• 3 – Future Nine
• 4 – CallCentric
• 5 – DIDlogic
• 6 – IPcomms
• 7 – Les.net
• 8 – Vitelity
• 9 – VoIP.ms

For free iNUM calling worldwide, the following dialing prefixes are supported in conjunction with the last seven digits of any destination iNUM DID. Free iNUM DIDs for your own PBX are available from both of these providers as well.

• 0XXXXXXX – CallCentric
• 90XXXXXXX – VoIP.ms

7. Configure a Softphone with Incredible PBX for Asterisk-GUI

We’re in the home stretch now. You can connect virtually any kind of telephone to your new Gotcha-Free PBX. Plain Old Phones require an analog telephone adapter (ATA) which can be a separate board in your computer from a company such as Digium. Or it can be a standalone SIP device such as ObiHai’s OBi100 or OBi110 (if you have a phone line from Ma Bell to hook up as well). SIP phones can be connected directly so long as they have an IP address. These could be hardware devices or software devices such as the YateClient softphone. We’ll start with a free one today so you can begin making calls. You can find dozens of recommendations for hardware-based SIP phones both on Nerd Vittles and the PIAF Forum when you’re ready to get serious about VoIP telephony.

We recommend YateClient which is free. Download it from here. Run YateClient once you’ve installed it and enter the credentials for the 6002 extension on Incredible PBX. You’ll need the IP address of your server plus your extension 6002 password. Choose Users -> 6002 and write down your SIP/IAX Password. You can also find it in /root/passwords.FAQ. Fill in the blanks using the IP address of your server, 6002 for your account name, and whatever password is assigned to the extension. Click OK to save your entries.

Once you are registered to extension 6002, close the Account window. Then click on YATE’s Telephony Tab and place some test calls to the numerous apps that are preconfigured on Incredible PBX. Dial a few of these to get started:

7001 - IVR Demo
123 - Reminders
947 - Weather by ZIP Code
951 - Yahoo News
*61 - Time of Day
TODAY - Today in History


If you are a Mac user, another great no-frills softphone is Telephone. Just download and install it from the Mac App Store.

Configuring Google Voice

If you want to use Google Voice, you’ll need a dedicated Google Voice account to support Incredible PBX. The more obscure the username (with some embedded numbers), the better off you will be. This will keep folks from bombarding you with unsolicited Gtalk chat messages, and who knows what nefarious scheme will be discovered using Google messaging six months from now. So keep this account a secret!

IMPORTANT: Be sure to enable the Google Chat option as one of your phone destinations in Settings, Voice Setting, Phones. That’s the destination we need for The Incredible PBX to work its magic! Otherwise, all inbound and outbound calls will fail. Good News! You’re in luck. Google has apparently had a change of heart on discontinuing Google Chat support so it’s enabled by default in all new Google Voice accounts. Once you’ve created a Gmail and Google Voice account, go to Google Voice Settings and click on the Calls tab. Make sure your settings match these:

• Call Screening – OFF
• Call Presentation – OFF
• Caller ID (In) – Display Caller’s Number
• Caller ID (Out) – Don’t Change Anything
• Do Not Disturb – OFF
• Call Options (Enable Recording) – OFF
• Global Spam Filtering – ON

Click Save Changes once you’ve adjusted your settings. Under the Voicemail tab, plug in your email address so you get notified of new voicemails. Down the road, receipt of a Google Voice voicemail will be a big hint that something has come unglued on your PBX.

One final word of caution is in order regardless of your choice of providers: Do NOT use special characters in any provider passwords, or nothing will work!

Now you’re ready to configure your Google Voice account in Incredible PBX. You can do it from within Asterisk-GUI by choosing Google Voice within the Incredible PBX Apps tab. Once you entered your credentials, don’t forget to restart Asterisk, or Google Voice calls will fail. If you still have trouble placing or receiving calls, try these tips.

OK, Smarty Pants: Show Me the Beef!

We know what some of you are thinking. "What does a fast food worker really know about VoIP and Gotcha-Free PBXs?? Before I waste a bunch of time on this, show me the beef!" Fair enough. Sit by your phone and click the Call Me icon below. Type in a fake name and your real phone number. Click the Connect button, answer your phone when it rings, and press 1. You’ll be connected to the Incredible PBX IVR for Asterisk-GUI. Pick an option from the menu of choices and take the Incredible PBX apps for a spin on our dime… actually it’s Google’s dime. Everything you see and hear is part of what you get with Incredible PBX for Asterisk-GUI including the ability to set up your own click-to-dial web interface exactly like this one. The demo just happens to be running on our Mac desktop instead of yours. So… what are you waiting for? Click away and try Incredible PBX for yourself. And, by the way, nobody besides the NSA and Google will be monitoring your call. 😉

1. Checking Current Status of Incredible PBX

There are several ways to check the status of your server. First, log into your server as root and type: status or pbxstatus

The second option is to use a browser to access your server. Choose the Admin menu. Then click Asterisk-GUI Administration. Once you log in, the System Status of your server, trunks, and extensions will be displayed.

Finally, with your browser, choose the Admin menu. Click System Information to bring up the terrific SysInfo application that’s included in Incredible PBX.

2. Adding Speech Recognition to Incredible PBX for Asterisk-GUI

Google changed the licensing of their speech recognition engine last year and now restricts use to "personal and development use." Assuming you qualify, the very first order of business is to enable speech recognition for your new PBX. Once enabled, the Incredible PBX feature set grows exponentially. You’ll have access to the Voice Dialer for AsteriDex, Worldwide Weather Reports where you can say the name of a city and state or province to get a weather forecast for almost anywhere, Wolfram Alpha for a Siri-like encyclopedia for your PBX, and Lefteris Zafiris’ speech recognition software to build additional Asterisk apps limited only by your imagination.

Here’s how to activate speech recognition on Incredible PBX. Don’t skip any steps!

1. Using an existing Google/Gmail account, you first must join the Chrome-Dev Group.

2. Using the same account, create a new Speech Recognition Project.

3. Click on your newly created project and choose APIs & auth.

4. Turn ON the Speech API by clicking on its Status button in the far right margin. HINT: If you forgot to complete Step #1, the Speech API option will be missing!

5. Click on Credentials in APIs & auth and choose Create New Key -> Server key. Leave the IP address restriction blank!

6. Write down your new API key or copy it to the clipboard.

7. Log into your server as root and issue the following command:

nano -w /var/lib/asterisk/agi-bin/speech-recog.agi

8. When the nano editor opens, go to line 70 of speech-recog.agi: my $key = "". Insert your API key from Step #6 above between the quotation marks and save the file: Ctrl-X, Y, then Enter.

Congratulations! Speech recognition is now available with Incredible PBX applications for Asterisk-GUI.

3. Using Wolfram Alpha with Incredible PBX for Asterisk-GUI

Ever wished your Asterisk server could harness the power of a 10,000 CPU Supercomputer to answer virtually any question you can dream up about the world we live in? Well, so long as it’s for non-commercial use, today’s your lucky day. Apple demonstrated with Siri™ just how amazing this technology can be by coupling Wolfram Alpha® to a speech-to-text engine on the iPhone. Now you can do much the same thing using voice recognition on the Incredible PBX for Asterisk-GUI.

Before using Wolfram Alpha from any phone connected to your PBX, you first must configure it by obtaining and adding a Wolfram Alpha application ID to Incredible PBX. Here are the simple steps:

1. Obtain your free Wolfram Alpha APP-ID here.

2. Log into your server as root and issue the following command:

nano -w /var/lib/asterisk/agi-bin/4747

3. When the nano editor opens, the top line of the file will look like this:

APPID="Your-Wolfram-Alpha-App-ID-Goes-Here"

4. Replace the text between the quotes with your APP_ID key from Step #1 above. Then save the file: Ctrl-X, Y, then Enter.

To use Wolfram Alpha, dial 4747 (that’s S-I-R-I backwards) from any extension.

Here are some sample queries to get you started:

Weather in Charleston South Carolina
Weather forecast for Washington D.C.

Doughnut (you don’t wanna know)
Snickers bar (ditto)
Weather (local weather at your server’s location)

4. Automatic Update Utility for Incredible PBX for Asterisk-GUI

A key security component of Incredible PBX is its Automatic Update Utility. Each time you log into your server as root, the Automatic Update Utility is run. It installs the latest fixes and security patches for your server. Don’t disable it! In fact, don’t delete anything from the /root folder. You’ll need all of it sooner or later.

We recommend you log into your server as root at least once a week to keep your server current. Ditto for the web interface to Incredible PBX. Insofar as security is concerned, we make a best effort to keep the components of Incredible PBX up to date. The Linux operating system was installed by you before the Incredible PBX install began. That’s a nice way of saying Linux security is primarily your responsibility. When an egregious Linux vulnerability comes along that we know about, we will try to notify you of the issue on the PIAF Forum and on the RSS Feed that is part of the Incredible PBX web GUI. Check the RSS Feed on the web GUI at least once a week as well. As a condition of use of the free Incredible PBX for Asterisk-GUI product, you accepted ultimate responsibility for the security and reliability of your server. None of this discussion changes any of that.

5. Asterisk 11 Upgrade Utility for Incredible PBX for Asterisk-GUI

We’ve included a script to upgrade Asterisk 11 to the latest version whenever you feel the urge. Before beginning the upgrade, log into your server as root using SSH and maximize the window. Otherwise, Asterisk may not compile properly. Then run the script: /root/upgrade-asterisk-to-current

6. Implementing Apache Authentication with Incredible PBX for Asterisk-GUI

With the exception of Asterisk-GUI and WebMin, all web-based applications included in Incredible PBX (including your trunk setups!) require successful Apache authentication to gain access. When you installed Incredible PBX, you should have created an admin account. If not, issue the following command using a secure password after logging in as root:

htpasswd -b /etc/pbx/wwwpasswd admin newpassword

With the exception of AsteriDex and Reminders, you gain access to other Incredible PBX applications with the admin Apache account. For the remaining apps, you may wish to (but don’t have to) assign different account names and passwords to various departments in your organization. To set up these accounts, use the syntax above substituting the name of the department for "admin" and the department password for "newpassword."

7. Managing the IPtables Linux Firewall and WhiteList

As installed, Incredible PBX for Asterisk-GUI includes a preconfigured, locked-down Linux firewall that restricts incoming IPv6 traffic to localhost and, via a WhiteList, limits incoming IPv4 traffic to your server’s public and private IP addresses, your desktop computer’s IP address (that was used for the install), private LAN and NeoRouter VPN traffic, and a collection of our favorite SIP providers. You can WhiteList additional IP addresses for additional providers or for SIP and IAX phones located outside your firewall. The following firewall management scripts are mostly installed in the /root directory:

• ./add-ip — WhiteList an additional IP address or IP address range (CIDR)
• ./add-fqdn — WhiteList a site using a fully-qualified domain name (FQDN)
• ./del-acct — Remove previously designated entry from the WhiteList
• ./ipchecker — Check whether specified FQDNs have changed & update IPtables
• iptables-restart — Used exclusively to restart IPtables and test for failed FQDNs
• iptables -nL — Check the current status of your IPtables firewall

IPtables can be manually configured (if you know what you’re doing) by editing iptables and ip6tables in /etc/sysconfig (CentOS) or rules.v4 and rules.v6 in /etc/iptables (Debian/Ubuntu). NEVER use traditional iptables commands such as iptables save to update your IPtables configuration, or you will permanently delete all of your FQDN entries! Instead, edit the files directly and then restart IPtables using iptables-restart. This protects the FQDN entries in your setup while also checking for invalid FQDN entries and removing them temporarily so that IPtables will successfully restart. If you use service iptables restart to restart IPtables and there happens to be an FQDN entry for a host that is either down or has disappeared, IPtables will fail to restart and your server will be left with NO firewall protection! The reason for this is the IPtables design which converts all FQDN entries to fixed IP addresses when it starts up. It’s also the reason we have to periodically check for changed FQDN entries using the ipchecker script with cron. For this to work properly, you will need to manually add your FQDN setups to the top of /etc/ipchecker by inserting the filenames of any add-fqdn entries you have created. For additional details, read our Travelin’ Man 3 tutorial.

8. PortKnocker Remote Access to Incredible PBX for Asterisk-GUI

IPtables is a powerful firewall that keeps the bad guys out. It also will keep legitimate users (including you) from gaining remote access to your server unless you had the forethought to WhiteList your remote IP address before you left on that family vacation. Unfortunately, you don’t always know your IP address in advance. And dynamic IP addresses assigned with hotel WiFi frequently change. To address this problem, Incredible PBX for Asterisk-GUI includes a preconfigured PortKnocker utility. This lets you send three secret "knocks" on random TCP ports to your server to tell it to let you in temporarily (until IPtables is again restarted).

For PortKnocker to work, you obviously need to know the secret knocks. You’ll find them in /root/knock.FAQ. Record them in your wallet or inside your suitcase for that rainy day! There are PortKnocker apps for almost all smartphones as well as for Windows, Mac, and Linux computers. Install your favorite AND test access before you leave town.

Finally, be aware that PortKnocker does not need any special access to your server to work; however, if your server is behind a hardware-based firewall, then you must map the three PortKnocker TCP ports to the private IP address of your server, or the knocks obviously will never get delivered to your server.

Review our PortKnocker tutorial for additional configuration tips.

9. Travelin’ Man 4 Remote Access to Incredible PBX for Asterisk-GUI (Dial TM4)

In addition to PortKnocker, Incredible PBX also includes a telephone-based solution to temporarily gain remote access to your server. This does require a bit of preplanning since you must create account credentials for the person to whom you wish to give remote access via a phone call. The complete tutorial for Travelin’ Man 4 is available on the PIAF Forum. All of the pieces already are in place on your server so skip down to the Configuration & Operation sections for details on implementation. The tutorial also covers the Administrator Utilities in /root/tm4 which let you set up remote user accounts.

10. Using the Conference Bridge in Incredible PBX (Dial C-O-N-F)

A new turnkey Asterisk 11 Conference Bridge has been added to Incredible PBX for Asterisk-GUI. A conference bridge allows a group of people to participate in a joint phone call. Typically, participants dial into a virtual meeting room from their own phone. This virtual meeting room supports dozens or even hundreds of participants depending upon server capacity.

You do not need a timing source for conferencing with Incredible PBX for Asterisk-GUI! Old-style Asterisk-GUI Conference Rooms which required a timing source are disabled.

To access the Conference Bridge, dial C-O-N-F (2663) from any phone connected to your server. Remote users can be added to a conference by providing a DID that points to an IVR which includes Conference Bridge access. Once connected to the conference bridge, a caller is prompted for the Conference Bridge PIN and his or her name. The user and admin passwords to access the Conference Bridge are randomized during the install.

To display Conference Bridge PINs, open Asterisk-GUI, choose Incredible PBX Apps, and click on Anveo Direct. The Miscellaneous Credentials Settings will all be displayed at the bottom of the screen including your Conference Bridge PINs.

To change Conference Bridge PINs, log into your server as root and edit the entries for CONF_USER_PIN and CONF_ADMIN_PIN: nano -w /etc/asterisk/credentials.conf. Then reload Asterisk: asterisk-reload.

11. CallerID Name (CNAM) Lookups with Incredible PBX for Asterisk-GUI

By default, Incredible PBX is configured to automatically provide OpenCNAM CallerID name lookups for the first ten calls received each hour. These lookups are only from cached entries in the OpenCNAM database; however, you can enable the commercial lookup service if desired. The cost is four tenths of a cent per successful query.

To enable the OpenCNAM Professional Tier, set up an account at OpenCNAM.com. Once you’ve obtained your credentials, edit the [cidlookup] context in /etc/asterisk/extensions_additional.conf. The second line includes this CURL command:

${CURL(https://api.opencnam.com/v2/phone/${CALLERID(num)}?format=pbx&ref=incrediblepbx)})

Add the following immediately after "incrediblepbx" replacing ACCOUNT_SID and AUTH_TOKEN with your actual credentials: &account_sid=ACCOUNT_SID&auth_token=AUTH_TOKEN

Finally, comment out the next 8 lines that begin with "exten => cidlookup_1,n" by inserting a semicolon at the start of each line. DO NOT comment out: exten => cidlookup_1,n,Return(). Save your changes and reload Asterisk: asterisk-reload.

;exten => cidlookup_1,n,Set(current_hour=${STRFTIME(,,%Y-%m-%d %H)})
;exten => cidlookup_1,n,Set(last_query_hour=${DB(cidlookup/opencnam_last_query_hour)})
;exten => cidlookup_1,n,Set(total_hourly_queries=${DB(cidlookup/opencnam_total_hourly_queries)})
;exten => cidlookup_1,n,ExecIf($["${last_query_hour}" != "${current_hour}"]?Set(DB(cidlookup/opencnam_total_hourly_queries)=0))
;exten => cidlookup_1,n,ExecIf($["${total_hourly_queries}" = ""]?Set(DB(cidlookup/opencnam_total_hourly_queries)=0))
;exten => cidlookup_1,n,Set(DB(cidlookup/opencnam_total_hourly_queries)=${MATH(${DB(cidlookup/opencnam_total_hourly_queries)}+1,i)})
;exten => cidlookup_1,n,ExecIf($[${DB(cidlookup/opencnam_total_hourly_queries)} >= 10]?System(${ASTVARLIBDIR}/bin/opencnam-alert.php))
;exten => cidlookup_1,n,Set(DB(cidlookup/opencnam_last_query_hour)=${current_hour})
exten => cidlookup_1,n,Return()

12. Faxing with Incredible PBX for Asterisk-GUI

If you added Incredible Fax to your server by running incrediblefax11-GUI.sh in the /root folder, then you’re in for a treat. As part of the install, you provided an email address for delivery of incoming faxes. That’s all the setup that is required to have incoming faxes sent to most of your DIDs delivered via SendMail in PDF format. The best way to figure out whether a particular provider supports fax technology on their DIDs is to send a test fax to yourself. FaxZERO lets you send 5 free faxes of up to 3 pages every day. Give it a whirl.

You also can send faxes using standard document types with the AvantFax web application. Log into AvantFax from the main Incredible PBX page by clicking on the AvantFax icon. Choose the Send a Fax option from the main menu, fill in the blanks, and attach your document. AvantFax uses the default dialplan documented in last week’s article so use the prefix desired to send the fax using your preferred provider. HINT: Google Voice does an excellent job with both incoming and outgoing faxes, and the calls are free in the U.S. and Canada.

Copies of all incoming faxes also are available for retrieval within AvantFax.

13. Voicemail 101 for Incredible PBX for Asterisk-GUI

Voicemail functionality is enabled on an extension-by-extension basis as part of the extension setup under the Users tab in Asterisk-GUI. Once enabled, you can set up your mailbox and retrieve your messages by dialing *98. You can leave a message for any extension without actually calling the extension. Just prepend * to any extension number before dialing, e.g. *6002. A number of the system settings for voicemail can be tweaked under the Voicemail tab in Asterisk-GUI. You also can automatically delete voicemails once they have been delivered by email under the Email Settings tab. Just follow your nose.

14. Email Delivery of MP3 Voicemails with Incredible PBX for Asterisk-GUI

Speaking of email delivery, your voicemails also can be delivered to any email address of your choosing. For every extension under the Users tab in Asterisk-GUI, simply add an Email Address in the Voicemail section of the form. With Incredible PBX, the voicemail message will be attached to the email in MP3 format so it’s suitable for playback with most email clients on desktop PCs, Macs, and smartphones. Be advised that some Internet service providers (such as Comcast) block downstream SMTP servers. You can check whether your outbound email is flowing by accessing WebMin (below) and choosing Servers -> SendMail Mail Server -> Mail Queue. If you find outbound mail is accumulating, then you’ll need to add your ISP’s SMTP server address as a SmartHost for SendMail as documented in the next section.

15. Reconfiguring SendMail for SmartHost SMTP Delivery Of Outgoing Emails

Many residential Internet service providers block downstream SMTP servers such as the SendMail server running with Incredible PBX for Asterisk-GUI. If you’re sending emails but they never arrive and you’ve checked your SPAM folder, then chances are your ISP is the culprit. The simple solution is to add your ISP’s SMTP server as a SmartHost for SendMail. This means outbound emails will be forwarded to your ISP for actual email transmission over the Internet. Here’s how. Edit /etc/mail/sendmail.cf and search for DS. Immediately after DS, add the FQDN of your ISP’s SMTP server, e.g. DSsmtp.comcrap.net (no spaces!). Save the file and then restart SendMail: service sendmail restart. Your email and voicemail messages with attachments should begin flowing without further delay.

Email from: Asterisk PBX asterisk@pbx.local...
"Nerd Vittles" at 8001234567 left a new voicemail message 1 for extension 6002 on Thursday, January 29, 2015 at 01:42:33 PM.

You can test email delivery by sending yourself a message from the Linux CLI:

echo "test" | mail -s testmessage yourname@somedomain.com

16. SMS Blasting with Google Voice and Incredible PBX for Asterisk-GUI

Out of the box, Incredible PBX supports SMS Message Blasting if you have a functioning Google Voice account set up. Before first use, you must add your credentials, address list, and text message to the SMS Blaster scripts in the /root folder.

In smsblast, insert your credentials:

GVACCT="yourname@gmail.com"
GVPASS="yourpassword"
MSGSUBJECT="Little League Alert"

In smslist.txt, insert one or more recipients for your message. These can be a combination of SMS addresses and email addresses and will be delivered accordingly.

NOTE: For most cellphone providers, you also can send an email message for SMS delivery by the provider. The complete list of providers is available here. Email messaging for SMS requires that you know the cellphone provider for your recipient while standard SMS messaging does not.

# In lieu of SMS number, email is also OK
8431234567 Doe John
mary@doe.com Doe Mary
8435551212@txt.att.net Mr T

In smsmsg.txt, enter the text message to be sent.

Once you have all three files configured, run the script: /root/smsblast.

17. Voice-Activated SMS Messaging with Incredible PBX (Dial S-M-S)

In addition to message blasting, you also can dial 767 from any extension and dictate an SMS message to send through your Google Voice account. When prompted for the destination, simply enter the 10-digit SMS number of the recipient.

18. SMS Messaging with VoIP.ms and Incredible PBX for Asterisk-GUI

Incredible PBX for Asterisk-GUI also supports SMS messaging through VoIP.ms if you have an account and an SMS-enabled DID. See the VoIP.ms wiki for setup info on the VoIP.ms side.

To install the VoIP.ms SMS scripts, follow these steps:

cd /root
mkdir sms-voip.ms
cd sms-voip.ms
wget http://incrediblepbx.com/voipms-SMS.tar.gz
tar zxvf voipms-SMS.tar.gz

Edit voipms-sms.php and insert your VoIP.ms number that supports SMS messaging (no spoofing allowed!):

$SMSsender="8005551212";

Edit class.voipms.php and insert your VoIP.ms API credentials:

    /*******************************************\
     *  VoIPms - API Credentials
    \*******************************************/
    var $api_username   = 'yourname@youremail.com';
    var $api_password   = 'yourpassword';

Send an SMS message through VoIP.ms with the following command where smsnumber is the 10-digit number of the SMS recipient and "sms message" is the text message surrounded by quotes:

/root/sms-voip.ms/voipms-sms.php smsnumber "sms message"

NOTE: VoIP.ms has indicated that sooner or later there will be a penny per message charge for SMS messages; however, as of today, they’re still free.

19. SIP URI Calling with Incredible PBX for Asterisk-GUI (Demo: Dial L-E-N-N-Y)

With one line of dialplan code, you can add Speed Dials for free SIP URI calling worldwide. The dialplan code is stored in the [CallingRule_SIP_URI] context in extensions_custom.conf. Just clone one of the existing entries, designate an extension to dial to connect to the SIP URI, and enter the SIP URI for the destination. Numerous SIP providers support assignment of SIP URI’s to DIDs for unlimited free calling from anywhere in the world. Here’s a sample using a speed dial code of 53669 that connects you to SIP URI 2233435945@sip2sip.info: exten = 53669,1,Dial(SIP/2233435945@sip2sip.info)

20. IVR Demo of Incredible PBX Applications (Dial 7001)

The easiest way to try out a number of the Incredible PBX applications is to take the IVR Demo for a spin. Just pick up any phone and dial 7001. The sample code for the IVR is available for review and modification in extensions.conf. Just search for 7001. You can create your own IVRs and AutoAttendants under the Voice Menus tab in Asterisk-GUI. There’s also a sample Stealth AutoAttendant available by dialing 7000. This plays a brief greeting and then rings Ring Group #1. During the greeting, you could configure the application to allow button presses to branch to other applications on your PBX, hence the Stealth name since the codes are not disclosed to callers.

21. Incredible Backup & Restore with Incredible PBX for Asterisk-GUI

Incredible Backup and Restore scripts are included in the /root folder. These scripts make and restore snapshots of the settings on your server and should be used in conjunction with a full system backup solution. Asterisk-GUI includes its own backup snapshots under the Backup tab.

22. AsteriDex – The Poor Man’s Rolodex

AsteriDex is a web-based phonebook application for Incredible PBX. You can access it from the main web menu. Scripts are also available to import your contacts from Outlook and Google Contacts.

23. Voice Dialing with AsteriDex (Dial 411)

If you have voice recognition enabled on your server, you can call anyone in your AsteriDex database by dialing 411.

24. Speed Dialing with AsteriDex (Dial 412 or 000+)

For those without voice recognition, Incredible PBX includes two speed dialing utilities. The first is accessed by dialing 412. Then enter any 3-digit dialcode from your AsteriDex database to complete the call. If you’d prefer to skip the intermediate step, dial 000 + the 3-digit speed dial code desired. The call will be placed immediately using your default outbound routes. For those using a version of Incredible PBX before February 2015, see this link for the 000 Speed Dial patch.

For a complete listing of your AsteriDex dial codes, execute this query:

mysql -u root -ppassw0rd asteridex -e "select name,dialcode from user1 order by name"

25. Telephone Reminders (Dial 123)

Incredible PBX includes a sophisticated reminders system that lets you schedule individual or recurring reminders using your phone by dialing 123 or a web browser. A complete tutorial is available here. For phone reminders, a password is required to access the reminder system. You’ll find your password in /root/passwords.FAQ. It can be changed in /etc/asterisk/credentials.conf. Typically, these reminders set up a return call at a scheduled time that then plays back either a recorded message or a TTS message generated from the text you entered in the browser application. Incredible PBX for Asterisk-GUI also includes a new addition that lets you schedule web reminders that are delivered by email or SMS message. Links to the web-based reminders applications are in the main Incredible PBX web menu.

26. DISA Access with Incredible PBX for Asterisk-GUI (Dial D-I-S-A)

Direct Inward System Access (aka DISA) is one of the great PBX inventions of the last 50 years. It’s also one of the most dangerous. It lets someone connect to your PBX and obtain dial tone to place an outbound call using your trunks… on your nickel. Typically, it is offered as an option with an IVR or AutoAttendant. The DISA extension is preconfigured with Incredible PBX on extension 3472 (D-I-S-A). Use requires a password. Your randomized password can be found in /root/passwords.FAQ. It can be changed in /etc/asterisk/credentials.conf. Make it very secure before exposing DISA access to the outside world!

27. Yahoo! News (Dial 951)

Yahoo! news headlines are available by dialing 951. The news option also is included in the sample IVR application.

28. Weather Forecasts by Phone (Dial 949 or Z-I-P)

If you have voice recognition enabled on your server, you can retrieve a weather report for most cities in the world by dialing 949 and saying the name of the city plus the state, province, or country. For PBXs without voice recognition, you can obtain a weather forecast for most zip codes by dialing 947 (Z-I-P) and entering the 5-digit zip code.

29. ODBC Application Support for Asterisk

If you’ve recently logged into your server as root, Automatic Update #4 added ODBC/MySQL application support for Asterisk. You can try out a few sample applications that are included to get you started. Dial 222 and enter 12345 for the employee number. This retrieves an employee name from the MySQL timeclock database using Asterisk. Dial 223 to retrieve an AsteriDex name and phone number by entering the 3-character dialcode. You then have the option of placing the call by pressing 1. Once you have created accounts for Travelin’ Man 4, you can dial 864 (T-M-4) to WhiteList an IP address for that account after entering the account number and matching PIN. Use the * key for periods in the IP address. The code for all of the samples is in the following files in /etc/asterisk: odbc.conf and func_odbc.conf. If you create new MySQL databases, remember to add corresponding entries in res_odbc.conf and /etc/odbc.ini. Then restart Asterisk: asterisk-restart.

30. Today in History (Dial T-O-D-A-Y)

It’s always interesting to find out what happened Today in History. And Incredible PBX now delivers it by phone. Just dial 86329 (T-O-D-A-Y) for a walk down memory lane.

31. Time of Day

Speaking of yesteryear, if you grew up dialing TI-4-1212 for the time of day, Ma Bell may have discontinued the service, but we haven’t. Now you can do it on your very own PBX. Just dial into the IVR (7001) and choose option 4.

But suppose you want your users to be able to dial in for the time directly by dialing extension 8463 (T-I-M-E). Well it’s easy. Just add one line to your Incredible PBX dialplan and then reload the dialplan.

sed -i '/CallingRule_extensions_custom/a exten => 8463,1,Goto(new-time,s,1)' /etc/asterisk/extensions_custom.conf
asterisk-reload

NOTE: Those with a Feb. 2015 or later version of Incredible PBX already have this feature.

Introducing WebMin: The Linux Swiss Army Knife

There is no finer Linux application than WebMin. There is no more dangerous Linux application than WebMin. You’ve been warned. We heartily recommend WebMin as a tool to LOOK at your server’s settings. We strongly discourage changing anything in WebMin unless you totally know what you are doing. This is especially true with management of Linux applications that make up the core of Incredible PBX: the Linux kernel, SendMail, IPtables, Apache, MySQL, PHP, and…

To access WebMin, click on the WebMin link in the main Incredible PBX web menu. The username is root. The password is your root password. WebMin has root privileges to your server. Reread paragraph 1 and act accordingly.

For an exhaustive tutorial on WebMin, download The Book of WebMin by Joe Cooper. For a more recent commercial offering, take a look at Michal Karzyński’s WebMin Administrator’s Cookbook.

Introducing phpMyAdmin: The MySQL Swiss Army Knife

The same caveats we expressed regarding WebMin apply to phpMyAdmin. It is a powerful tool for managing MySQL databases in the right hands. It is a dangerous tool in the wrong hands. Fortunately, Asterisk-GUI does not rely upon MySQL for anything, and we are phasing out the remaining Incredible PBX applications that still rely upon it. So there should be little need to use phpMyAdmin unless you are developing a customized database solution for your business. We’ve included phpMyAdmin just in case.

To access phpMyAdmin, click on the phpMyAdmin link in the main Incredible PBX web menu. For tutorials on phpMyAdmin, see the phpMyAdmin wiki. For an excellent commercial offering focused on the version of phpMyAdmin installed on your server, consider Mastering phpMyAdmin 3.4 for Effective MySQL Management by Marc Delisle.

Some Recent Nerd Vittles Articles of Interest…

[iframe-popup id="5″]
To celebrate ITEXPO® this week, we’re back in the gift-giving mood. So today we’re pleased to introduce the first of several new turnkey VoIP solutions for the Asterisk® platform. Incredible PBX™ for Asterisk-GUI provides virtually the same feature set of applications for Asterisk as our previous releases. But this time around, you get a Gotcha-Free PBX with pure and honest open source GPL code. No patent, trademark, or copyright minefields to trip you up. Just abide by the clear GPL licensing terms and copy, embellish, and redistribute to your heart’s content. Incredible PBX for Asterisk-GUI is truly a lean, mean implementation designed to be frugal with memory and extremely versatile in terms of configuration.

One of our favorite Twitter detractors recently compared us to a fast food worker.¹ We’ve been called worse so thanks. Keeping up with Five Guys ain’t easy. Leveraging the best open source components available and putting them together in such a way that the end result far exceeds the sum of its parts is the name of the game. We started by assembling the very best components for Asterisk we could find. Take it from a fast food worker, Mark Spencer’s Asterisk and Asterisk-GUI creations are anything but second-rate products. The GUI may not have made good business sense for Digium, but making money wasn’t the objective this time around. Our focus was building a better VoIP mousetrap and a Gotcha-Free PBX.

We began by dusting off Mark Spencer’s terrific GUI and giving it a facelift. We tweaked it for use with Asterisk 11 and Google Voice and ConfBridge. Then we preconfigured some SIP trunks from our favorite providers, added the best open source text-to-speech and voice recognition tools available from Lefteris Zafiris, and produced a VoIP solution and set of applications for home and SOHO businesses that’s ready to take and make calls in less time than refueling your vehicle. But why drive a Lincoln (and we’re being charitable) when an F-150 will get the job done? Unlike some other distros, you get the very latest version of Asterisk and Asterisk-GUI. Both are compiled from source on your hardware platform to maximize performance. The end result is the VoIP Trifecta… better, cheaper, and faster.

Since the early Windows® days, we haven’t been big fans of GUI-only interfaces. Let’s face it. Some things can be configured more efficiently with less chance for error using other tools. Incredible PBX takes advantage of this hybrid technology by offering the best of all worlds. Administrators can use a GUI where it makes sense and use a text editor or simple web form where it doesn’t. You can configure 8 VoIP trunks from 8 great providers in under 5 minutes. And there’s so much more…

Target Audience: Home or SOHO/SBO in need of a turnkey, Gotcha-Free PBX Default Configuration: Asterisk 11 with enhanced Asterisk-GUI, Kennonsoft GUI, and NANPA dialplan Platform: CentOS 6.5/6.6 running on Dedicated Server, Cloud-Based Server, or Virtual Machine Minimum Memory: 512MB Recommended Disk: 20GB+ Default Trunks: Google Voice, CallCentric, DIDlogic, Future-Nine, IPcomms, Les.net, Vitelity, VoIP.ms2 Feature Set: Fax, SMS messaging, VPN, Reminders, ConfBridge Conferencing, AsteriDex, Voicemail, Email, IVR, News, Weather, Voice Dialer, Wolfram Alpha, Today in History, TM3 Firewall WhiteList, Speed Dialer, iNUM and SIP URI (free) worldwide calling, OpenCNAM CallerID lookups, DISA, Call Forwarding, CSV CDRs Administrator Utilities: Incredible Backup/Restore, Automatic Updater, Asterisk Upgrader, phpMyAdmin, Timezone Config, Plug-and-Play Trunk Configurator, WebMin, External IP Setup, Firewall WhiteList Tools

Getting Started with Incredible PBX for Asterisk-GUI (CentOS Edition)

Here’s a quick overview of the installation and setup process for Incredible PBX for Asterisk-GUI:

1. Choose a Hardware Platform – Dedicated PC, Cloud Provider, or Virtual Machine
2. Install a Linux Flavor – 32-bit or 64-bit CentOS 6.5 or Scientific Linux Minimal ISO (so far!)
3. Download and Install Incredible PBX for Asterisk-GUI
4. Install Incredible Fax for Asterisk-GUI (optional)
5. Set Up Passwords for Incredible PBX for Asterisk-GUI
6. Configure Trunks with Incredible PBX for Asterisk-GUI
7. Connect a Softphone to Incredible PBX for Asterisk-GUI

1. Choose a Platform for Incredible PBX for Asterisk-GUI

Incredible PBX for Asterisk-GUI works equally well on dedicated hardware, a cloud-based server, or a virtual machine. Just be sure you’ve met the minimum requirements outlined above and that you have a sufficiently robust Internet connection to support 100Kb of download and upload bandwidth for each simultaneous call you wish to handle with your new PBX.

For Dedicated Hardware, we recommend an Atom-based PC of recent vintage with at least a 30GB drive and 4GB of RAM. That will take care of an office with 10-20 extensions and a half dozen or more simultaneous calls if you have the Internet bandwidth to support it.

For Cloud-Based Servers, we recommend RentPBX, one of our financial supporters who also happens to size servers properly and restrict usage solely to VoIP. This avoids performance bottlenecks that cause problems with VoIP calls. If you’re just experimenting, then a 512MB Digital Ocean droplet is a cost-effective option at a cost of less than a penny an hour. In addition to a little referral revenue for Nerd Vittles, the nicest features of Digital Ocean are the availability of preconfigured CentOS images and a platform on which you can install Incredible PBX and be ready to start making calls very, very quickly. If you make a serious mistake during the install or setup, it’s a 30-second task to delete your droplet and create a new one. You’re only out a penny! And reloading Incredible PBX from scratch is never more than a 20-minute task. Remember to run the create-swapfile-DO script included in the Incredible PBX tarball before beginning your install to avoid out-of-memory conditions.

For Virtual Machine Installs, we recommend Oracle’s VirtualBox platform which runs atop almost any operating system including Windows, Macs, Linux, and Solaris. Here’s a link to our original VirtualBox tutorial to get you started. We suggest allocating 1GB of RAM and at least a 20GB disk image to your virtual machine for best performance.

2. Install a Linux Flavor for Incredible PBX for Asterisk-GUI

To be clear, we plan to support many Linux flavors other than RedHat. But Rome wasn’t built in a day so hang in there. We’re flippin’ burgers as fast as we can. For today, you’ll need a 32-bit or 64-bit version of CentOS or Scientific Linux 6.5/6.6. On some platforms, you install 6.5. After the initial update and upgrade steps, you’ll end up with 6.6. There are many flavors of CentOS and Scientific Linux. For Incredible PBX, a minimal install is all you need.

NOTICE: Core dumps reportedly are being experienced loading Asterisk on the 32-bit platform. We’re investigating. For the moment, stick with 64-bit installs until this message disappears.

With dedicated hardware, begin by downloading the 32-bit or 64-bit CentOS 6.6 minimal ISO. Boot your server with the ISO, and begin the install. Here are the simplest installation steps:

Choose Language and Click Continue
Click: Install Destination (do not change anything!)
Click: Done
Click: Network & Hostname
Click: ON
Click: Done
Click: Begin Installation
Click: Root Password: password, password, Click Done twice
Wait for Minimal Software Install and Setup to finish
Click: Reboot

With most cloud-based providers, you simply choose the CentOS 6.5 platform in creating your initial image. 512MB of RAM is plenty so long as you have a swap file. Within a minute or two, you’re ready to boot up the server.

For VirtualBox, download the Scientific Linux 6.6 minimal install .ova image from SourceForge. Then double-click on the image to load it into VirtualBox. Enable Audio and configure Network with Bridge Adapter in Settings. Then start the virtual machine. Default password for root is password.

With VirtualBox, you can skip this step. For everyone else, log into your server as root and issue the following commands to put the basic pieces in place and to reconfigure your Ethernet port as eth0. On some platforms, some of the commands may generate errors. Don’t worry about it! Just make a note of your IP address so you can log back in with SSH from a desktop computer to begin the Incredible PBX install.

For CentOS/Scientific Linux 6.5 minimal install:

setenforce 0
yum -y upgrade
yum -y install net-tools nano wget
ifconfig
sed -i 's|quiet|quiet net.ifnames=0 biosdevdame=0|' /etc/default/grub
grub2-mkconfig -o /boot/grub2/grub.cfg
wget http://incrediblepbx.com/update-kernel-devel
chmod +x update-kernel-devel
./update-kernel-devel
reboot

For CentOS/Scientific Linux 6.6 minimal install:

setenforce 0
yum -y upgrade
yum -y install net-tools nano wget
ifconfig
reboot

3. Download and Install Incredible PBX for Asterisk-GUI

Before beginning the install, make sure your terminal window size is at least 80 characters wide and 27 lines high.

Otherwise, Asterisk will not compile properly. UPDATE: This has been resolved in the latest Incredible PBX installer so terminal window expansion is no longer required.

cd /root
yum -y install wget
wget http://incrediblepbx.com/incrediblepbx11gui.tar.gz
tar zxvf incrediblepbx11gui.tar.gz
#./create-swapfile-DO  #add this step for Digital Ocean droplets
rm -f incrediblepbx11gui.tar.gz
sed -i 's|pbxinaflash.com|incrediblepbx.com|' IncrediblePBX11-GUI.sh
sed -i 's|pkgs.repoforge.org/rpmforge-release|incrediblepbx.com|' IncrediblePBX11-GUI.sh
sed -i 's|https://iksemel.googlecode.com/files|http://pkgs.fedoraproject.org/repo/pkgs/iksemel/iksemel-1.4.tar.gz/532e77181694f87ad5eb59435d11c1ca|' IncrediblePBX11-GUI.sh
./IncrediblePBX11-GUI.sh
./IncrediblePBX11-GUI.sh
sed -i 's|myip.pbxinaflash.com|myip.incrediblepbx.com|' /usr/local/sbin/status

4. Install Incredible Fax for Asterisk-GUI (optional)

Administrators have been trying to stomp out faxing for at least two decades. Here’s a hint. It ain’t gonna happen. So go with the flow and add Gotcha-Free Faxing to your server. It’ll be there when you need it. And sooner or later, you’ll need it. This install script is simple enough for any monkey to complete. Run the script and enter the email address for delivery of your faxes. Then, if you’re in the U.S. or Canada, press the Enter key to accept every default entry during the HylaFax and AvantFax installation steps. For other countries, read the prompts and answer accordingly. When the installation finishes, reboot your server to bring faxing on line. Be sure to change your AvantFax admin password. By default, it is password. You can use the script included in the /root folder: avantfax-pw-change. REMINDER: Don’t forget to reboot your server!

cd /root
./incrediblefax11-GUI.sh
./avantfax-pw-change
reboot

Troubleshooting: If your IAXmodems don’t display with a green IDLE notation in the AvantFax GUI, you may need to restart them once more. After a second reboot, all should be well. The restart command is /root/iaxmodem-restart.

5. Initial Configuration of Incredible PBX for Asterisk-GUI

Incredible PBX is installed with the preconfigured IPtables Linux firewall already in place. It implements WhiteList Security to limit server access to connected LANs, your server’s IP address, your desktop computer’s IP address, and a few of our favorite SIP providers. You can add additional entries to this WhiteList whenever you like using the add-ip and add-fqdn tools in /root. There’s also an Apache security layer for our web applications. And, of course, Asterisk-GUI has its own security methodology using Asterisk’s manager.conf. Finally, we randomize extension and DISA passwords as part of the initial install process. Out of the starting gate, you won’t find a more secure VoIP server implementation anywhere. After all, it’s your phone bill.

Even with all of these layers of security, here are 10 Quick Steps to better safeguard your server. You only do this once, but failing to do it may lead to security issues you don’t want to have to deal with down the road. So DO IT NOW!

First, log into your server as root with your root password and do the following:

Make your root password very secure: passwd
Set your correct time zone: ./timezone-setup
Create admin password for web apps: htpasswd -b /etc/pbx/wwwpasswd admin newpassword
Make a copy of your other passwords: cat passwords.FAQ
Make a copy of your Knock codes: cat knock.FAQ
Decipher IP address and other info about your server: status

Second, log into your server as admin using a web browser pointed to your server’s IP address:

Click USERS tab in Incredible PBX GUI
Click Asterisk-GUI Administration
Log in as user: admin with password: password
Immediately change your admin password and login again

Log in to Asterisk-GUI again with your new password. Expand the options available in the GUI:

Options -> Advanced Options -> Show Advanced Options

Last but not least, Incredible PBX includes an automatic update utility which downloads important updates whenever you log into your server as root. We recommend you log in once a week to keep your server current. Now would be a good time to log out and back into your server at the Linux command line to bring your server up to current specs.

6. Configure Trunks with Incredible PBX for Asterisk-GUI

Now for the fun part. If this is your first VoIP adventure, be advised that this ain’t your grandma’s phone system. You need not and should not put all your eggs in one basket when it comes to telephone providers. In order to connect to Plain Old Telephones, you still need at least one provider. But there is nothing wrong with having several. And a provider that handles an outbound call (termination) need not be the same one that handles an incoming call (origination) and provides your phone number (DID). We cannot recommend Vitelity highly enough, and it’s not just because they have financially supported our projects for almost a decade. They’re as good as VoIP providers get, and we use lots of them. If you’re lucky enough to live in the U.S., you’d be crazy not to set up a Google Voice account. It’s free as are all phone calls to anywhere in the U.S. and Canada. The remaining preconfigured providers included in Incredible PBX for Asterisk-GUI are equally good, and we’ve used and continue to use almost all of them. So pick a few and sign up. You only pay for the calls you make with each provider so you have little to lose by choosing several. The PIAF Forum includes dozens of recommendations on VoIP providers if you want additional information.

With the preconfigured trunks in Incredible PBX for Asterisk-GUI, all you need are your credentials for each provider and the FQDN of their server. Log into Asterisk-GUI Administration as admin using a browser. From the System Status screen, click Incredible PBX Apps. Click on each provider you have chosen and fill in the blanks with your credentials. When you’ve saved all of your settings, log into your server as root via SSH and type: service asterisk restart or asterisk-restart. You can also issue the command in the Asterisk-GUI by choosing the Asterisk CLI tab³ in the left column. Doesn’t get any simpler!

Update: It should be noted that Incredible PBX for Asterisk-GUI also supports Anveo Direct trunks; however, they are configured differently because of the way Anveo handles the calls. You’ll need the PIN provided by Anveo to set up your trunk, and Anveo supports CallerID spoofing so you can enter any CallerID number for the trunk that you are authorized to use. You’ll find the Anveo Direct setup link in the Incredible PBX Apps tab. To route an outgoing call through Anveo trunk, dial 2 + any desired 10-digit number.

Here is the complete list of dialing prefixes and the trunks to which they are associated:

• 1 – Google Voice
• 2 – Anveo Direct
• 3 – Future Nine
• 4 – CallCentric
• 5 – DIDlogic
• 6 – IPcomms
• 7 – Les.net
• 8 – Vitelity
• 9 – VoIP.ms

For free iNUM calling worldwide, the following dialing prefixes are supported in conjunction with the last seven digits of any destination iNUM DID. Free iNUM DIDs for your own PBX are available from both of these providers as well.

• 0XXXXXXX – CallCentric
• 90XXXXXXX – VoIP.ms

7. Configure a Softphone with Incredible PBX for Asterisk-GUI

We’re in the home stretch now. You can connect virtually any kind of telephone to your new Gotcha-Free PBX. Plain Old Phones require an analog telephone adapter (ATA) which can be a separate board in your computer from a company such as Digium. Or it can be a standalone SIP device such as ObiHai’s OBi100 or OBi110 (if you have a phone line from Ma Bell to hook up as well). SIP phones can be connected directly so long as they have an IP address. These could be hardware devices or software devices such as the YateClient softphone. We’ll start with a free one today so you can begin making calls. You can find dozens of recommendations for hardware-based SIP phones both on Nerd Vittles and the PIAF Forum when you’re ready to get serious about VoIP telephony.

We recommend YateClient which is free. Download it from here. Run YateClient once you’ve installed it and enter the credentials for the 6002 extension on Incredible PBX. You’ll need the IP address of your server plus your extension 6002 password. Choose Users -> 6002 and write down your SIP/IAX Password. You can also find it in /root/passwords.FAQ. Fill in the blanks using the IP address of your server, 6002 for your account name, and whatever password is assigned to the extension. Click OK to save your entries.

Once you are registered to extension 6002, close the Account window. Then click on YATE’s Telephony Tab and place some test calls to the numerous apps that are preconfigured on Incredible PBX. Dial a few of these to get started:

7001 - IVR Demo
123 - Reminders
947 - Weather by ZIP Code
951 - Yahoo News
*61 - Time of Day
TODAY - Today in History


If you are a Mac user, another great no-frills softphone is Telephone. Just download and install it from the Mac App Store.

Configuring Google Voice

If you want to use Google Voice, you’ll need a dedicated Google Voice account to support Incredible PBX. The more obscure the username (with some embedded numbers), the better off you will be. This will keep folks from bombarding you with unsolicited Gtalk chat messages, and who knows what nefarious scheme will be discovered using Google messaging six months from now. So keep this account a secret!

IMPORTANT: Be sure to enable the Google Chat option as one of your phone destinations in Settings, Voice Setting, Phones. That’s the destination we need for The Incredible PBX to work its magic! Otherwise, all inbound and outbound calls will fail. Good News! You’re in luck. Google has apparently had a change of heart on discontinuing Google Chat support so it’s enabled by default in all new Google Voice accounts. Once you’ve created a Gmail and Google Voice account, go to Google Voice Settings and click on the Calls tab. Make sure your settings match these:

• Call Screening – OFF
• Call Presentation – OFF
• Caller ID (In) – Display Caller’s Number
• Caller ID (Out) – Don’t Change Anything
• Do Not Disturb – OFF
• Call Options (Enable Recording) – OFF
• Global Spam Filtering – ON

Click Save Changes once you’ve adjusted your settings. Under the Voicemail tab, plug in your email address so you get notified of new voicemails. Down the road, receipt of a Google Voice voicemail will be a big hint that something has come unglued on your PBX.

One final word of caution is in order regardless of your choice of providers: Do NOT use special characters in any provider passwords, or nothing will work!

Now you’re ready to configure your Google Voice account in Incredible PBX. You can do it from within Asterisk-GUI by choosing Google Voice within the Incredible PBX Apps tab. Once you entered your credentials, don’t forget to restart Asterisk, or Google Voice calls will fail. If you still have trouble placing or receiving calls, try these tips.

OK, Smarty Pants: Show Me the Beef!

We know what some of you are thinking. "What does a fast food worker really know about VoIP and Gotcha-Free PBXs?? Before I waste a bunch of time on this, show me the beef!" Fair enough. Sit by your phone and click the Call Me icon below. Type in a fake name and your real phone number. Click the Connect button, answer your phone when it rings, and press 1. You’ll be connected to the Incredible PBX IVR for Asterisk-GUI. Pick an option from the menu of choices and take the Incredible PBX apps for a spin on our dime… actually it’s Google’s dime. Everything you see and hear is part of what you get with Incredible PBX for Asterisk-GUI including the ability to set up your own click-to-dial web interface exactly like this one. The demo just happens to be running on our Mac desktop instead of yours. So… what are you waiting for? Click away and try Incredible PBX for yourself. And, by the way, nobody besides the NSA and Google will be monitoring your call. 😉

Nerd Vittles Demo IVR Options
1 – Call by Name (say “Delta Airlines” or “American Airlines” to try it out)
2 – MeetMe Conference (password is 1234)
3 – Wolfram Alpha (say “What planes are overhead?”)
4 – Lenny (The Telemarketer’s Worst Nightmare)
5 – Today’s News Headlines
6 – Weather Forecast (say the city and state, province, or country)
7 – Today in History
8 – Speak to a Real Person (or maybe just voicemail if we’re out)

Homework Assignment: Mastering the Asterisk-GUI

We’ll have more to say about the Incredible PBX applications next week. In the meantime, you have some homework. You need to learn all about Asterisk-GUI and how to make the best use of its powerful feature set. Here’s one word of warning. We mentioned that Incredible PBX was a hybrid system that combines some customized settings with the standard Asterisk-GUI interface. Before modifying existing settings for the default trunks, extensions, and default routes, take a look at the credentials* files in /etc/asterisk. If you modify any of these trunk entries or the Outgoing or Incoming Call Rules in Asterisk-GUI, you may break the Incredible PBX setup. So steer clear of that minefield until you know what you’re doing. Adding new extensions and additional trunks is perfectly fine and will not break anything.

Rather than reinvent the wheel, we’ll point you to some excellent tutorials that already have been written. Start with Chapter 3 of Digium’s Asterisk Appliance™ Administrator Manual. Next, review Chapter 11 of The Asterisk Book (Second Edition). Finally, take a look at a couple of the tutorials that have been written by other companies that incorporated Asterisk-GUI into their hardware products, e.g. Yeastar’s MyPBX SOHO User Manual and Grandstream’s UCM6100 User Manual. Then check back with us next week for Chapter 2.

In the meantime, if you have questions, join the PBX in a Flash Forums and take advantage of our awesome collection of gurus. There’s an expert available on virtually any topic, and the price is right. As with Incredible PBX, it’s absolutely free.

We also are quickly building a collection of tutorials tailored specifically for Incredible PBX for Asterisk-GUI:

• Gotcha-Free PBX: Scripts 101
• Gotcha-Free PBX: Inbound Call Routing
• Gotcha-Free PBX: Outbound Call Routing
• Gotcha-Free PBX: Add-a-Trunk
• Gotcha-Free PBX: SMTP Mail Relay with SendMail or PostFix
• Gotcha-Free PBX: Music on Hold
• Gotcha-Free PBX: Changing TTS Engine
• Gotcha-Free PBX: Voicemail with Email Attachments
• Gotcha-Free PBX: Telephone and Web Reminders

Some Recent Nerd Vittles Articles of Interest…

1. What made the comment all the more humorous was the fact that it was made by a person who has bounced from company to company to company in the VoIP industry, not unlike the plight of many fast food workers. Takes one to know one, I suppose. [↩]
2. Vitelity and Google provide financial support to Nerd Vittles and the Incredible PBX project. [↩]
3. If, for some reason, the Asterisk CLI tab does not appear on your server, click Options -> Advanced Options -> Show Advanced Options. [↩]
