Midnight Madness: Introducing Incredible PBX 12 with Asterisk 12 and FreePBX

The number “12” always has held mystical prominence in our culture and so it is with Asterisk®. Just over 12 months ago, Digium first introduced Asterisk 12 at AstriCon in Atlanta and heralded a major change in the direction of the product. It was more than a wholesale revamping of the Asterisk feature set. There was a revolutionary new development methodology thanks to the untiring efforts of Matt Jordan and his incredibly talented development team. Unlike Asterisk releases of old, there were no serious breakages in existing applications and, where there were changes, they were carefully documented for all the world to see. Thank you, Matt & Co.

The release of Asterisk 12 also set in motion the development of FreePBX® 12 by the equally talented FreePBX Dev Team. What began as an effort simply to integrate all of the new components in Asterisk 12 quickly evolved into a major rewrite of the graphical user interface for Asterisk, no small feat given its history of starts and stops spanning nearly a decade of development. Just last week, FreePBX 12 was pronounced stable and production ready. If you thought Asterisk 12 was revolutionary, just wait until you try FreePBX 12. Simply amazing work by the FreePBX Development Team. Thank you.

While PBX in a Flash has offered a preview edition of Asterisk 12 and FreePBX 12 for quite a while, we’ve held off releasing the stand-alone Incredible PBX 12 for a number of reasons. First and foremost, we wanted Incredible PBX 12 to remain pure open source to point the way for others that want to enhance Asterisk 12 and FreePBX 12. Second, there were more than a few rough edges with both products that simply needed some time to evolve. The one year anniversary of Asterisk 12 and the stable release of FreePBX 12 seemed a fitting occasion to add our turnkey implementation of Incredible PBX to the mix.

The real beauty of Incredible PBX: there is no smoke and there are no mirrors. What you see is what you get. You begin with a base install of the Linux operating system. And then the open source Incredible PBX installer adds all of the pieces to integrate air-tight security with Asterisk 12, FreePBX 12, text-to-speech technology and dozens of applications for Asterisk into a seamless platform for either experimentation or production use. You can review the source code and embellish it as you see fit! Protecting your deployment is the IPtables firewall with a WhiteList for authorized user access coupled with Fail2Ban to monitor access attempts. This isn’t merely a security toolkit. Your server is actually locked down from the moment you complete the Incredible PBX install. Authorizing additional users is accomplished using simple administrator scripts. Or end-users can employ PortKnocker and Travelin’ Man 4 to simplify remote access. Automatic updates for security fixes and enhancements are an integral component of Incredible PBX. If the security alerts of the past month haven’t convinced you that updates are critically important, you probably should stop hosting your own PBX. Backups and restores also are simple. And the complete open source feature set of both Asterisk and FreePBX is activated to facilitate your development efforts. In short, you gain nothing by installing the individual components yourself, and you may lose a lot. With Incredible PBX, the heavy lifting has all been done for you with documented, open source code that makes it simple to add your own tweaks as desired. That’s what open source is all about!

We’ve chosen Ubuntu 14.04 as the platform on which to begin the Incredible PBX 12 adventure. More releases will follow in due course. But Ubuntu 14.04 is an extremely stable and well-supported LTS release of Linux that warrants a careful look. After all, the primary objective here is a stable telephony platform. The Ubuntu 14.04 LTS platform offers that in spades.

Building an Ubuntu 14.04 Platform for Incredible PBX 12

As a result of the trademark and copyright morass, we’ve steered away from the bundled operating system in favor of a methodology that relies upon you to put in place the operating system platform on which to run PBX in a Flash or Incredible PBX. The good news is it’s easy! With many cloud-based providers1, you can simply click a button to choose your favorite OS flavor and within minutes, you’re ready to go. With many virtual machine platforms such as VirtualBox, it’s equally simple to find a pre-built Ubuntu 14.04 image or roll your own.

If you’re new to VoIP or to Nerd Vittles, here’s our best piece of advice. Don’t take our word for anything! Try it for yourself in the Cloud! You can build an Ubuntu 14.04 image on Digital Ocean in under one minute and install Incredible PBX 12 for Ubuntu 14.04 in under 30 minutes. Then try it out for two full months. It won’t cost you a dime. Use our referral link to sign up for an account. Enter a valid credit card to verify you’re who you say you are. Create an Ubuntu 14.04 (not 14.10!) 512MB droplet of the cheapest flavor ($5/mo.). Go to the Billing section of the site, and enter the following promo code: UBUNTUDROPLET. That’s all there is to it. A $10 credit will be added to your account, and you can play to your heart’s content. Delete droplets, add droplets, and enjoy the free ride!

For today, we’ll walk you through building your own stand-alone server using the Ubuntu 14.04 mini.iso. If you’re using Digital Ocean in the Cloud, skip down to Installing Incredible PBX 12. If you’re using your own hardware, to get started, download the 32-bit or 64-bit Ubuntu 14.04 “Trusty Tahr” Minimal ISO from here. Then 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 those that would prefer to build your Ubuntu 14.04 Wonder Machine using VirtualBox on any Windows, Mac, or existing Linux Desktop, here are the simple steps. 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. Simple!

Here are the steps to get Ubuntu 14.04 humming on your new server or virtual machine once you’ve booted up. If you can bake cookies from a recipe, you can do this:

UBUNTU mini.iso install:
Choose language
Choose timezone
Detect keyboard

Installing Incredible PBX 12 on Your Ubuntu 14.04 Server

Adding Incredible PBX 12 to a running Ubuntu 14.04 server is a walk in the park. 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.

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.

Now let’s begin the Incredible PBX 12 install. Log back in as root and issue the following commands:

cd /root
wget http://incrediblepbx.com/incrediblepbx12.tar.gz
tar zxvf incrediblepbx12.tar.gz
rm incrediblepbx12.tar.gz
#./create-swapfile-DO
./IncrediblePBX12.sh

The installer will first upgrade your Ubuntu 14.04 build to the latest modules. Then it will reboot. Rerun the installer again to kick off the Incredible PBX 12 installation process. Once you have agreed to the license agreement and terms of use, press Enter and go have a 30-minute cup of coffee. The Incredible PBX 12 installer runs unattended so find something to do for a bit unless you just like watching code compile. When you see “Have a nice day”, your installation is complete. Write down your your three “knock” ports for PortKnocker. You can retrieve your PortKnocker setup like this: cat /root/knock.FAQ. Next, set your admin password for FreePBX 12 by running /root/admin-pw-change. Set your correct time zone by running /root/timezone-setup. To be sure your FreePBX module signatures are current, issue the following two commands:

amportal a ma refreshsignatures
amportal a r

Log out and back in as root and the automatic update utility will bring your system current with security fixes and enhancements. Then you will be greeted with a status display shown at the top of this article.

You can access the Asterisk 12 CLI by typing: asterisk -rvvvvvvvvvv

You can access the FreePBX 12 GUI using your favorite web browser to configure your server. Just enter the IP address shown in the status display. The default username is admin with the admin password you set up above. If desired, you also can change it in FreePBX Administration by clicking Admin -> Administrators -> admin. Enter a new password and click Submit Changes then Apply Config. Now edit extension 701 so you can figure out (or change) the randomized passwords that were set up for default 701 extension and voicemail: Applications -> Extensions -> 701.

Setting Up a Soft Phone to Use with Incredible PBX

Now you’re ready to set up a telephone so that you can play with Incredible PBX 12. We recommend YateClient which is free. Download it from here. Run YateClient once you’ve installed it and enter the credentials for the 701 extension on Incredible PBX. You’ll need the IP address of your server plus your extension 701 password. Choose Settings -> Accounts and click the New button. Fill in the blanks using the IP address of your server, 701 for your account name, and whatever password you created for the extension. Click OK.

Once you are registered to extension 701, 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:

123 - Reminders
222 - ODBC Demo (use acct: 12345)
947 - Weather by ZIP Code
951 - Yahoo News
*61 - Time of Day
*68 - Wakeup Call
TODAY - Today in History

Now you’re ready to connect to the telephones in the rest of the world. If you live in the U.S., the easiest way (at least for now) is to use an existing (free) Google Voice account. Google has threatened to shut this down but as this is written, it still works with previously set up Google Voice accounts. The more desirable long-term solution is to choose several SIP providers and set up redundant trunks for your incoming and outbound calls. The PIAF Forum includes dozens of recommendations to get you started.

Configuring Google Voice

If you want to use Google Voice, you’ll need a dedicated Google Voice account to support Incredible PBX 12. If you want to use the inbound fax capabilities of Incredible Fax, then you’ll need an additional Google Voice line that can be routed to the FAX custom destination using FreePBX. 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!

We’ve tested this extensively using an existing Google Voice account, and inbound calling is just not reliable. The reason seems to be that Google always chooses Gmail chat as the inbound call destination if there are multiple registrations from the same IP address. So, be reasonable. Do it our way! Use a previously configured and dedicated Gmail and Google Voice account, and use it exclusively with Incredible PBX 12.

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 don’t see this option, you’re probably out of luck. Google has disabled the option in newly created accounts as well as some old ones that had Google Chat disabled. Now go back to the Google Voice Settings.

While you’re still in Google Voice Settings, click on the Calls tab. Make sure your settings match these:

  • Call ScreeningOFF
  • Call PresentationOFF
  • Caller ID (In)Display Caller’s Number
  • Caller ID (Out)Don’t Change Anything
  • Do Not DisturbOFF
  • Call Options (Enable Recording)OFF
  • Global Spam FilteringON

Click Save Changes once you adjust 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 set up your Google Voice trunk in FreePBX 12. After logging into FreePBX with your browser, click the Connectivity tab and choose Google Voice/Motif. To Add a new Google Voice account, just fill out the form. If you want unanswered calls to be routed to Google Voice for transcription, check the box. Be advised that IVR calls typically are not “answered” so check that box as well if you plan to use an IVR to respond to incoming Google Voice calls.

IMPORTANT LAST STEP: Google Voice will not work unless you restart Asterisk from the Linux command line at this juncture. Using SSH, log into your server as root and issue the following command: amportal restart.

If you have trouble getting Google Voice to work (especially if you have previously used your Google Voice account from a different IP address), try this Google Voice Reset Procedure. It usually fixes connectivity problems.

Troubleshooting Audio and DTMF Problems

You can avoid one-way audio on calls and touchtones that don’t work with these simple settings in FreePBX: Settings -> Asterisk SIP Settings. Just plug in your public IP address and your private IP subnet. Then set ULAW as the only Audio Codec.

Adding Speech Recognition to Incredible PBX 12

To support many of our applications, Incredible PBX has included Google’s speech recognition service for years. These applications include Weather Reports by City (949), AsteriDex Voice Dialing by Name (411), and Wolfram Alpha for Asterisk (4747), all of which use Lefteris Zafiris’ terrific speech-recog AGI script. Unfortunately (for some), Google now has tightened up the terms of use for their free speech recognition service. Now you can only use it for “personal and development use.” If you meet those criteria, keep reading. Here’s how to activate speech recognition on Incredible PBX. Don’t skip any steps!

1. Using an existing Google/Gmail account to 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 Speech API by clicking on its Status button in the far right margin.

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 commands:

# for Ubuntu and Debian platforms
apt-get clean
apt-get install libjson-perl flac -y
# for RedHat and CentOS platforms
# yum -y install perl-JSON
# for all Linux platforms
cd /var/lib/asterisk/agi-bin
mv speech-recog.agi speech-recog.last.agi
wget --no-check-certificate https://raw.githubusercontent.com/zaf/asterisk-speech-recog/master/speech-recog.agi
chown asterisk:asterisk speech*
chmod 775 speech*
nano -w 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.

Now you’re ready to try out the speech recognition apps. Dial 949 and say the name of a city and state/province/country to get a current weather forecast from Yahoo. Dial 411 and say “American Airlines” to be connected to American.

To use Wolfram Alpha by phone, you first must install it. Obtain your free Wolfram Alpha APP-ID here. Then run the one-click installer: /root/wolfram/wolframalpha-oneclick.sh. Insert your APP-ID when prompted. Now dial 4747 to access Wolfram Alpha by phone and enter your query, e.g. “What planes are overhead.” Read the Nerd Vittles tutorial for additional examples and tips.

A Few Words about the Incredible PBX 12 Security Model for Ubuntu

Incredible PBX 12 for Ubuntu 14.04 is an extremely secure turnkey PBX implementation. As configured, it is protected by both Fail2Ban and a hardened configuration of the IPtables Linux firewall. As installed, nobody can access your PBX without your credentials AND an IP address that is either on your private network or that matches the IP address of your server or the PC from which you installed Incredible PBX. Incredible PBX 12 is preconfigured to let you connect to many of the leading SIP hosting providers without additional firewall tweaking.

You can whitelist additional IP addresses for remote access in several ways. First, you can use the command-line utilities: /root/add-ip and /root/add-fqdn. You can also remove whitelisted IP addresses by running /root/del-acct. Second, you can dial into extension 864 (or use a DID pointed to extension 864 aka TM4) and enter an IP address to whitelist. Before Travelin’ Man 4 will work, you’ll need to add credentials for each caller using the tools in /root/tm4. You must add at least one account before dial-in whitelisting will be enabled. Third, you can temporarily whitelist an IP address by successfully executing the PortKnocker 3-knock code established for your server. You’ll find the details and the codes in /root/knock.FAQ. Be advised that IP addresses whitelisted with PortKnocker (only!) go away whenever your server is rebooted or the IPtables firewall is restarted. For further information on the PortKnocker technology and available clients for iOS and Android devices, review the Nerd Vittles tutorial.

HINT: The reason that storing your PortKnocker codes in a safe place is essential is because it may be your only available way to gain access to your server if your IP address changes. You obviously can’t use the command-line tools to whitelist a new IP address if you cannot gain access to your server at the new IP address.

We always recommend you also add an extra layer of protection by running your server behind a hardware-based firewall with no Internet port exposure, but that’s your call. If you use a hardware-based firewall, be sure to map the three PortKnocker ports to the internal IP address of your server!

The NeoRouter VPN client also is included for rock-solid, secure connectivity for remote users. Read our previous tutorial for setup instructions.

As one would expect, the IPtables firewall is a complex piece of software. If you need assistance configuring it, visit the PIAF Forum for some friendly assistance.

Incredible Backup and Restore

We’re pleased to introduce our latest backup and restore utilities for Incredible PBX. Running /root/incrediblebackup will create a backup image of your server in /tmp. This backup image then can be copied to any other medium desired for storage. To restore it to another Incredible PBX 12 server, simply copy the image to a server running Asterisk 12 and FreePBX 12 and run /root/incrediblerestore. Doesn’t get much simpler than that.

A Word About FreePBX Module Signatures

FreePBX 12 has implemented a new checksum mechanism to assure that modules are intact. Special thanks to the FreePBX Development Team for their work in extending this feature to modules outside the FreePBX-support modules. If other modules (other than ODBC configuration files) show invalid or missing signatures, you should do some investigating promptly!

Adding Incredible Fax to Your Server

Once you’ve completed the Incredible PBX install, log out and log back in to load the latest automatic updates. Then reboot. Now you’re ready to continue your adventure by installing Incredible Fax for Ubuntu. Special thanks to Josh North for all his hard work on this!

cd /root
rm incrediblefax11_ubuntu14.sh
wget http://incrediblepbx.com/incrediblefax11_ubuntu14.sh
chmod +x incrediblefax11_ubuntu14.sh
./incrediblefax11_ubuntu14.sh

Just plug in your email address for delivery of your incoming faxes in PDF format. Then accept all of the defaults during the installation process. Once you complete the install, reboot your server. Then log in as root again and set your AvantFax admin password: /root/avantfax-pw-change. Now you can access both FreePBX 12 and AvantFax by pointing your browser to the IP address of your server. Please note that we’ve had problems logging into AvantFax with some versions of the Chrome browser. Works great with Firefox!

Next, log into FreePBX and set an Inbound Route for incoming faxes to Custom Destination: Fax (hylafax). Then try sending a fax to the phone number and be sure it arrives in your email.

You also can try enabling fax detection with any Google Voice number. Just edit the inbound route for the DID and make it look like this:

Incredible PBX 12 Automatic Update Utility

Every time you log into your server as root, Incredible PBX 12 will ping the IncrediblePBX.com web site to determine whether one or more updates are available to bring your server up to current specs. We recommend you log in at least once a week just in case some new security vulnerability should come along (again).

Where To Go Next?

Once you get Incredible PBX installed, you’ll want to read up on the dozens of applications for Asterisk which are included in the Incredible PBX feature set. We’ve previously covered this in a separate article for the Raspberry Pi platform, but the applications are the same. Here’s a link to the tutorials.

You can follow updates to Incredible PBX 12 in this thread on the PIAF Forum.

We would also encourage you to sign up for an account on the PIAF Forum and join the discussion. In addition to providing first-class, free support, we think you’ll enjoy the camaraderie. Come join us!

30 Minutes to Paradise: Incredible PBX for Ubuntu 14.04 is Ready for Primetime

A few months ago, we introduced a preview of Incredible PBX for Ubuntu 14. And now we’re pleased to release the latest production-ready version with all the bells and whistles including Incredible Fax featuring HylaFax and AvantFax.

Introducing Incredible PBX 11 for Ubuntu 14.04

Today’s plan is to build a production-ready version of Incredible PBX with Ubuntu 14.04 that mimics the functionality of our previous builds with literally dozens of turnkey applications that show off the very best features of Asterisk®. If you believe in the open source community, this build is for you. No strings, no gotchas, and no quirky licenses!

Six months ago, we could barely spell Ubuntu. Then an enterprising young programmer named Eric Teeter shot us a script to install Ubuntu with Asterisk and FreePBX® and encouraged us to embellish it and to share the results with our Nerd Vittles audience. Having rarely met an operating system we didn’t like, we jumped at the opportunity knowing full well that Billy Chia at Digium and Tony Lewis at Schmooze Com had reported impressive results with Ubuntu years ago. It seemed like a good fit for Incredible PBX as well. Unlike CentOS, Ubuntu also was a platform that was easily transferable to the new $50 BeagleBone Black and the CuBox-i.

Our special thanks to Lefteris Zafiris for cleaning up all of the text-to-speech incompatibilities with Ubuntu. Within minutes from the other side of the world, Lefteris had logged into our Ubuntu Server in the Cloud and tamed the TTS beast. If ever there was an unsung hero in the Asterisk community, it’s Lefteris Zafiris. He has single-handedly kept all of the speech applications humming along through countless versions of Asterisk. We would have quit long ago without his untiring assistance. Thank you (again), Lefteris, for coming to the rescue.

Building an Ubuntu 14.04 Platform for Incredible PBX

Installing Incredible PBX on Your Ubuntu 14.04 Server

Adding Incredible PBX to a running Ubuntu 14.04 server is a walk in the park. 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, make sure to run the update step 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.

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

cd /root
wget http://incrediblepbx.com/incrediblepbx11.4.ubuntu14.tar.gz
tar zxvf incrediblepbx*
#./create-swapfile-DO
./Incredible*

Once you have agreed to the license agreement and terms of use, press Enter and go have a 30-minute cup of coffee. The Incredible PBX installer runs unattended so find something to do for a bit unless you just like watching code compile. When you see “Have a nice day”, your installation is complete. Write down your admin password for FreePBX as well as your three “knock” ports for PortKnocker. If you forget them, you can reset your admin password by running /root/admin-pw-change. And you can retrieve your PortKnocker setup like this: cat /root/knock.FAQ.

Log out and back in as root and you should be greeted with a status display that looks something like this:

You can access the Asterisk CLI by typing: asterisk -rvvvvvvvvvv

You can access the FreePBX GUI using your favorite web browser to configure your server. Just enter the IP address shown in the status display. The default username is admin with the randomized password you wrote down above. If desired, you can change them in FreePBX Administration by clicking Admin -> Administrators -> admin. Enter a new password and click Submit Changes then Apply Config. Now edit extension 701 so you can figure out (or change) the randomized passwords that were set up for default 701 extension and voicemail: Applications -> Extensions -> 701.

Setting Up a Soft Phone to Use with Incredible PBX

Now you’re ready to set up a telephone so that you can play with Incredible PBX. We recommend YateClient which is free. Download it from here. Run YateClient once you’ve installed it and enter the credentials for the 701 extension on Incredible PBX. You’ll need the IP address of your server plus your extension 701 password. Choose Settings -> Accounts and click the New button. Fill in the blanks using the IP address of your server, 701 for your account name, and whatever password you created for the extension. Click OK.

Once you are registered to extension 701, 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:

123 - Reminders
222 - ODBC Demo (use acct: 12345)
947 - Weather by ZIP Code
951 - Yahoo News
*61 - Time of Day
*68 - Wakeup Call
TODAY - Today in History

Now you’re ready to connect to the telephones in the rest of the world. If you live in the U.S., the easiest way (at least for now) is to use an existing (free) Google Voice account. Google has threatened to shut this down but as this is written, it still works with previously set up Google Voice accounts. The more desirable long-term solution is to choose several SIP providers and set up redundant trunks for your incoming and outbound calls. The PIAF Forum includes dozens of recommendations to get you started.

Configuring Google Voice

If you want to use Google Voice, you’ll need a dedicated Google Voice account to support Incredible PBX. If you want to use the inbound fax capabilities of Incredible Fax 11, then you’ll need an additional Google Voice line that can be routed to the FAX custom destination using FreePBX. 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!

We’ve tested this extensively using an existing Google Voice account, and inbound calling is just not reliable. The reason seems to be that Google always chooses Gmail chat as the inbound call destination if there are multiple registrations from the same IP address. So, be reasonable. Do it our way! Use a previously configured and dedicated Gmail and Google Voice account, and use it exclusively with Incredible PBX 11.

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 don’t see this option, you’re probably out of luck. Google has disabled the option in newly created accounts as well as some old ones that had Google Chat disabled. Now go back to the Google Voice Settings.

While you’re still in Google Voice Settings, click on the Calls tab. Make sure your settings match these:

  • Call ScreeningOFF
  • Call PresentationOFF
  • Caller ID (In)Display Caller’s Number
  • Caller ID (Out)Don’t Change Anything
  • Do Not DisturbOFF
  • Call Options (Enable Recording)OFF
  • Global Spam FilteringON

Click Save Changes once you adjust 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 set up your Google Voice trunk in FreePBX. After logging into FreePBX with your browser, click the Connectivity tab and choose Google Voice/Motif. To Add a new Google Voice account, just fill out the form. Do NOT check the third box or incoming calls will never ring!

IMPORTANT LAST STEP: Google Voice will not work unless you restart Asterisk from the Linux command line at this juncture. Using SSH, log into your server as root and issue the following command: amportal restart.

If you have trouble getting Google Voice to work (especially if you have previously used your Google Voice account from a different IP address), try this Google Voice Reset Procedure. It usually fixes connectivity problems.

Troubleshooting Audio and DTMF Problems

You can avoid one-way audio on calls and touchtones that don’t work with these simple settings in FreePBX: Settings -> Asterisk SIP Settings. Just plug in your public IP address and your private IP subnet. Then set ULAW as the only Audio Codec.

Adding Speech Recognition to Incredible PBX

To support many of our applications, Incredible PBX has included Google’s speech recognition service for years. These applications include Weather Reports by City (949), AsteriDex Voice Dialing by Name (411), and Wolfram Alpha for Asterisk (4747), all of which use Lefteris Zafiris’ terrific speech-recog AGI script. Unfortunately (for some), Google now has tightened up the terms of use for their free speech recognition service. Now you can only use it for “personal and development use.” If you meet those criteria, keep reading. Here’s how to activate speech recognition on Incredible PBX. Don’t skip any steps!

1. Using an existing Google/Gmail account to 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 Speech API by clicking on its Status button in the far right margin.

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 commands:

# for Ubuntu and Debian platforms
apt-get clean
apt-get install libjson-perl flac -y
# for RedHat and CentOS platforms
yum -y install perl-JSON
# for all Linux platforms
cd /var/lib/asterisk/agi-bin
mv speech-recog.agi speech-recog.last.agi
wget --no-check-certificate https://raw.githubusercontent.com/zaf/asterisk-speech-recog/master/speech-recog.agi
chown asterisk:asterisk speech*
chmod 775 speech*
nano -w 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.

Now you’re ready to try out the speech recognition apps. Dial 949 and say the name of a city and state/province/country to get a current weather forecast from Yahoo. Dial 411 and say “American Airlines” to be connected to American.

To use Wolfram Alpha by phone, you first must install it. Obtain your free Wolfram Alpha APP-ID here. Then run the one-click installer: /root/wolfram/wolframalpha-oneclick.sh. Insert your APP-ID when prompted. Now dial 4747 to access Wolfram Alpha by phone and enter your query, e.g. “What planes are overhead.” Read the Nerd Vittles tutorial for additional examples and tips.

A Few Words about the Incredible PBX Security Model for Ubuntu

Incredible PBX for Ubuntu 14 is our most secure turnkey PBX implementation, ever. As configured, it is protected by both Fail2Ban and a hardened configuration of the IPtables Linux firewall. As configured, nobody can access your PBX without your credentials AND an IP address that is either on your private network or that matches the IP address of your server or the PC from which you installed Incredible PBX. Incredible PBX is preconfigured to let you connect to many of the leading SIP hosting providers without additional firewall tweaking.

You can whitelist additional IP addresses for remote access in several ways. First, you can use the command-line utilities: /root/add-ip and /root/add-fqdn. You can also remove whitelisted IP addresses by running /root/del-acct. Second, you can dial into extension 864 (or use a DID pointed to extension 864 aka TM4) and enter an IP address to whitelist. Before Travelin’ Man 4 will work, you’ll need to add credentials for each caller using the tools in /root/tm4. You must add at least one account before dial-in whitelisting will be enabled. Third, you can temporarily whitelist an IP address by successfully executing the PortKnocker 3-knock code established for your server. You’ll find the details and the codes in /root/knock.FAQ. Be advised that IP addresses whitelisted with PortKnocker (only!) go away whenever your server is rebooted or the IPtables firewall is restarted. For further information on the PortKnocker technology and available clients for iOS and Android devices, review the Nerd Vittles tutorial.

HINT: The reason that storing your PortKnocker codes in a safe place is essential is because it may be your only available way to gain access to your server if your IP address changes. You obviously can’t use the command-line tools to whitelist a new IP address if you cannot gain access to your server at the new IP address.

We always recommend you also add an extra layer of protection by running your server behind a hardware-based firewall with no Internet port exposure, but that’s your call. If you use a hardware-based firewall, be sure to map the three PortKnocker ports to the internal IP address of your server!

The NeoRouter VPN client also is included for rock-solid, secure connectivity for remote users. Read our previous tutorial for setup instructions.

As one would expect, the IPtables firewall is a complex piece of software. If you need assistance configuring it, visit the PIAF Forum for some friendly assistance.

Adding Incredible Fax 11 to Your Server

Once you’ve completed the Incredible PBX install, log out and log back in to load the latest automatic updates. Then reboot. Now you’re ready to continue your adventure by installing Incredible Fax 11 for Ubuntu. Special thanks to Josh North for all his hard work on this!

cd /root
wget --no-check-certificate https://raw.githubusercontent.com/joshnorth/UbuntuPIAF/master/incrediblefax11_ubuntu14.sh
chmod +x incrediblefax11_ubuntu14.sh
./incrediblefax11_ubuntu14.sh

Just accept all of the defaults during the installation process. Once you complete the install, reboot your server and then set your AvantFax admin password: /root/avantfax-pw-change. Now you can access both FreePBX and AvantFax by pointing your browser to the IP address of your server. Please note that we’ve had problems logging into AvantFax with the most recent version of the Chrome browser. Works great with Firefox!

Incredible Backup and Restore

We’re pleased to introduce our latest backup and restore utilities for Incredible PBX. Running /root/incrediblebackup will create a backup image of your server in /tmp. This backup image then can be copied to any other medium desired for storage. To restore it to another Incredible PBX 11 server, simply copy the image to a server running Asterisk 11 and FreePBX 2.11 and run /root/incrediblerestore. Doesn’t get much simpler than that.

NEWS FLASH: More good news. If you decide you’d prefer another Linux platform, Incredible Backup and Restore will now let you migrate from one operating system to another. For details on the procedure, see this message thread.

Incredible PBX Automatic Update Utility

Every time you log into your server as root, Incredible PBX will ping the IncrediblePBX.com web site to determine whether one or more updates are available to bring your server up to current specs. We recommend you log in at least once a week just in case some new security vulnerability should come along.

In the meantime, we encourage you to sign up for an account on the PIAF Forum and join the discussion. In addition to providing first-class, free support, we think you’ll enjoy the camaraderie. Come join us!

Hardware Device of the Year: Meet the CuBox-i with Incredible PBX for Ubuntu

It’s been many years since we’ve written back-to-back articles about the same device. That should tell you how really special the CuBox-i is. After two weeks of 14-hour days developing the new Incredible PBX platform for CuBox, we are thrilled to crown this jewel as Nerd Vittles Hardware Device of the Year. Flawless design, incredible performance, tiny size, feature-rich components, minimal power consumption, and completely silent operation are merely the tip of the iceberg with this 2x2x2 cubic zircon. On the $130 CuBox-i4PRO, there’s a Quad Core processor, 2 gigs of RAM, a 10/100/1000 Ethernet port, a 1080p HDMI port, two powered USB 2 ports, an eSATA II port for an external drive, a realtime clock with backup battery, an Optical S/PDIF Audio Out port, a microSD port, an infrared receiver and transmitter, WiFi 11n, and Bluetooth plus a power adapter to match either American or European power sources. Whew! And here’s the best part. Everything works while squeezed in a tiny case that’s a third the size of Rubic’s Cube.

A SOHO Swiss Army Knife That Fits in Your Cupholder: Voice, Fax, SMS, TTS, Email, PBX, Incredible!

Did we mention it’s a near perfect VoIP platform for any home office or small business? Well, it is. And everything we’ve learned about Asterisk® and FreePBX® and Internet security over the past decade is rolled into today’s release of our crown jewel edition of Incredible PBX™ for the CuBox. First, you’ll need to purchase one and we strongly recommend the CuBox-i4PRO with its Quad Core ARM processor and built-in WiFi and Bluetooth. In the U.S, there’s NewEgg or NewEgg (10% off on i4PRO with promo code SW829NE10 = $117 until 9/4). In the U.K, there’s NewIT. For everyone else, you can buy directly from SolidRun, the creator.

Before we dive into Incredible PBX, we want to express our deepest appreciation to Zhando and Josh North of PIAF Forum fame. Zhando’s pioneering efforts with Ubuntu and Incredible PBX on the CuBox platform and Josh North’s morphing of Incredible Fax for deployment with Ubuntu paved the way for everything you’re about to read. It reinforces the spectacular results which can be achieved in the open source community when a talented group of even a few folks put their heads together. The Ubuntu developers and the tens of thousands of open source contributors from around the world also deserve a well-earned tip of the hat for producing a Linux platform that is rock-solid reliable and incredibly versatile. Nearly 1,000 open source packages are included in the latest Incredible PBX build. Click on the link to view the package list in PDF format and prepare to be amazed. We couldn’t have done it without all of you!

Introducing Incredible PBX 11.12.0 for the CuBox-i4PRO

If you’re new to Asterisk and the world of VoIP telephony, let us take a moment and explain how Incredible PBX fits into the puzzle. For lack of a better term, Incredible PBX on the CuBox platform is a turnkey aggregation in a bootable image that is based upon a superset of Ubuntu 14 packages plus Asterisk, the FreePBX GUI, and a sizable collection of applications for the Asterisk platform. You download a tarball, decompress it, write the image file to a microSD card, insert the card into your CuBox-i, and presto! You’ve got a turnkey PBX. Add credentials for a trunk or two to make and receive calls, connect some phones, and your whole office will come alive with a versatile PBX platform that used to cost organizations hundreds of thousands of dollars. What’s included in Incredible PBX? Glad you asked. Here’s a 3-minute video showcasing a few of our favorite Incredible PBX text-to-speech applications:


The Incredible PBX 11 Inventory. Here’s the current feature set on the CuBox platform. It’s the most robust ever! In addition to its superset of nearly 1,000 Ubuntu 14 packages, Asterisk 11, and FreePBX 2.11 with Apache, SendMail, MySQL, PHP, phpMyAdmin, Fail2Ban, WebMin, and the IPtables Linux firewall, check out these additions:

A Few Words About Security. Thanks to its Zero Internet Footprint™ design, Incredible PBX is different. It remains the most secure Asterisk-based PBX around. What this means is Incredible PBX has been engineered to sit anywhere, either behind a NAT-based, hardware firewall or directly on the Internet. No device other than those on your private LAN, a few of the major (trusted) SIP providers around the world, and those that you authorize on your WhiteList can even see your server. Additional IP addresses can be added to the WhiteList in three ways:

  1. An administrator registers new IP addresses using add-ip or add-fqdn from the Linux CLI
  2. A remote user sends the (correct) randomized PortKnock code assigned to your CuBox
  3. A remote user dials in from a standard telephone to register a new remote IP address

Read about this $100,000 VoIP phone bill, and you’ll better appreciate why WhiteList-based server security has become absolutely essential. WhiteList Security means only those devices with a registered IP address in your WhiteList can get to your server’s resources. To the NSA and everyone else, your server doesn’t even show up on the radar. Their only way to contact you is a POTS telephone using your published phone number. Our complete tutorial on Travelin’ Man 3 is available here. With Incredible PBX for CuBox, it’s installed and preconfigured.

Installing Incredible PBX 11.12.0 on the CuBox-i

There are five simple steps to get Incredible PBX up and running on your CuBox:

  1. Purchase a storage device
  2. Download Incredible PBX image
  3. Untar the image on your desktop
  4. Burn the image to a microSD card
  5. Insert microSD card in CuBox and boot

Choosing a Storage Platform. Unless you plan to run your server with an external eSATA hard drive (CuBox-i4PRO tutorial here), the first step is to purchase a suitable microSD card. We recommend at least a 32GB Class 10 card from Transcend, SanDisk, or Kingston. All of them are under $20 on Amazon and most include free 2-day shipping for Prime customers. If using an eSATA drive, you still need a microSD card to boot up, but any 4GB or 8GB card will suffice.1

Downloading Incredible PBX for CuBox. From your favorite desktop computer, download the latest build of Incredible PBX from SourceForge. Depending upon your network connection and the SourceForge mirror, it can take awhile. It’s a whopping 1.3GB!

Untarring Incredible PBX for CuBox. Depending upon your desktop platform, untarring incrediblepbx.4.cubox.U14.latest.tar.gz is as simple as double-clicking on it in the Downloads folder (on a Mac). On the Windows platform, here are 3 utilities that will do the job. On a Linux desktop, open a Terminal window and…

tar zxvf incrediblepbx.4.cubox.U14.latest.tar.gz

Burning the Incredible PBX image to microSD. Once you’ve untarred the file, you’ll find two scripts that make burning the image to a microSD card simple if you’re on a Mac or Linux desktop. On a Windows machine, it’s a little more complicated. Most SD cards come preformatted with a DOS partition so your Windows machine should recognize the microSD card when it’s inserted. If not, format the card using a utility such as SD Card Formatter. Next, you’ll need Win32 Disk Imager to burn cubox.img to your card. Once the image has been transferred, gracefully unmount the card from your desktop, and then remove the card from the SD card adapter.

Booting Incredible PBX on the CuBox. Insert the microSD card (electronics side up) into your CuBox-i. Then apply power to the CuBox after connecting a USB keyboard, HDMI monitor, and Ethernet cable to a network with Internet connectivity that can also hand out DHCP addresses. Log into Incredible PBX as root with cubox as your password. Your SSH credentials, Asterisk DUNDI secrets, logs, and network connection options will be initialized and then your server will reboot. You may need to hit the Enter key once or twice during the SSH credentials initialization to move things along. And, with some SD cards, you may find yourself waiting an eternity for the promised reboot. After seeing the “rebooting” message, count to ten. If your server still hasn’t rebooted, remove and reapply power. This quirk goes away after the first reboot.

After the reboot, log in again as root with password: cubox. Your firewall setup will be initialized to lock down your whitelist to your server’s public and private IP addresses AND the IP address of the machine from which you’re logging in. All of your FreePBX passwords will be randomized and your secret PortKnocker codes will be generated. The whole process only takes a few seconds.

When the second pass configuration is complete, you will be greeted by a welcoming message. STOP and read it. It has loads of important information about your server’s configuration and your next steps. Press ENTER to review status:

The Next 10 Steps. Before you do anything else, complete the following steps. It only takes a minute to secure and properly configure your server:

  1. Change your root password: passwd
  2. Change your FreePBX admin password: /root/admin-pw-change
  3. Set your correct time zone: /root/timezone-setup
  4. Expand partition to match microSD card size: /root/resize-partition
  5. Add any desired IP addresses to WhiteList: /root/add-ip
  6. Put PortKnocker credentials in a safe place: cat /root/knock.FAQ
  7. Change AvantFax admin password: /root/avantfax-pw-change
  8. Set Email Address for Incoming Faxes: /root/avantfax-email-dest
  9. Check status to be sure everything is working: status
  10. If using an eSATA external drive, do the migration drill (note the free disk space in status above)

A Few Important Tips. Every operating system and service provider has their quirks. Ask Bill Gates! Ubuntu and especially Comcast are no different. Fortunately, with Ubuntu, it’s a very short list.

1. Use the following commands (only!) to shutdown and restart your server: halt and reboot. These commands are reworked in Incredible PBX to gracefully shutdown important services so that files don’t get damaged. Please use them!

2. If you ever want to move your server to a different network, complete these three simple steps before you leave your existing network. This will trigger a new Phase I update (outlined above) and set the default network back to wired eth0 using DHCP the next time you boot your server.

touch /etc/update_hostconfig
/root/enable-eth0-only
# press Ctrl-C when prompted to reboot. then type:
halt

3. You really do need email connectivity to get the most out of Incredible PBX. It’s the way you receive important notifications from FreePBX, and it’s also how faxes and voicemail messages are delivered. From the Linux CLI, test your server to be sure you can send emails reliably:

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

After checking your spam folder, if you really didn’t get the email, it may be that your service provider is blocking downstream SMTP traffic. You can use your provider’s SMTP server as a smarthost to send out mail with SendMail. Just edit /etc/mail/sendmail.cf, search for DS, and add the provider’s SMTP server address immediately after it (no spaces!), e.g. DSsmtp.comcast.net or DSsmtp.knology.net. Then restart SendMail: service sendmail restart.

Once you’ve logged into FreePBX below, be sure to set your default email address in the right margin of Admin -> Module Admin and save your entry. This will assure receipt of timely notifications of FreePBX updates for your server.

4. If you’re sure you’ll never need remote access in an emergency, you can disable PortKnocker at startup and save about 5% of your processing cycles. Our complete PortKnocker tutorial is available here. To disable startup on boot, issue the following command from the Linux CLI:

update-rc.d -f knockd disable

5. The same applies to WebMin. We actually introduced one of the first tutorials for WebMin… over 9 years ago. A word to the wise: WebMin is a terrific tool for looking at stuff about your system. But be very careful making system changes with WebMin. You usually will break some of the customized settings in Incredible PBX. This is particularly true in the case of the IPtables firewall. To access WebMin, use a browser and the actual IP address of your server to go to: https://12.34.56.78:9001. Log in as root with your root password. To disable automatic startup of WebMin on boot:

update-rc.d -f webmin disable

Setting Up WiFi with the CuBox-i4PRO

This may sound simple now, but two weeks ago it was quite a different story. For those with a CuBox-i4Pro, WiFi is built into the hardware. The trick was getting it to work. Well, with Incredible PBX, it does. In the /root folder, you’ll find several self-explanatory scripts to do the heavy lifting for you. For options 2 and 3, you’ll need the SSID of the WiFi network you’ll be using as well as the SSID password.

  1. enable-eth0-only (the default setting)
  2. enable-wifi-eth0 (enables both but eth0 works with Asterisk)
  3. enable-wifi-only (runs your server purely on WiFi)

Getting Started with VoIP and FreePBX

Up to now, all of your time has been spent using the Linux CLI. That will be a rarity once you get this far. Henceforth, 90% of your time setting up Incredible PBX will be done using the FreePBX GUI and your favorite web browser. To access it, just point to the IP address of your server. status will tell you the address if you’ve forgotten it. The main control panel looks like this:

As configured, the default user account for both FreePBX and AvantFax administration is admin. The passwords are whatever you set in steps #2 and #7 above. As configured, email delivery of faxes with AvantFax is automatic so no further setup is required other than setting a delivery mechanism for faxes within FreePBX.

For those new to Asterisk and FreePBX, here’s a brief primer on what needs to happen before you can make and receive calls. If you have an existing Google Voice account or a smartphone that’s less than 2 years old, lucky you. This gets you a phone number for your PBX so people can call you. And it provides a vehicle to place calls to plain old telephones at little or no cost.

If you don’t have a Google Voice account or a shiny new smartphone, then you will need to purchase a SIP trunk from one of the numerous vendors around the world. Our favorite (because they provide terrific service at a modest price AND provide financial support to the Nerd Vittles, PBX in a Flash, and Incredible PBX projects) is Vitelity. Their special rates and a link for a discount are included at the end of today’s article.

Unlike POTS phone service from Ma Bell, the SIP World is a little different. First, you don’t need to put all your eggs in one basket. A trunk that gets you a phone number for incoming calls need not be with the same vendor that provides a trunk to place outbound calls. In fact, you may want multiple trunks for outbound calls just to have some redundancy. A list of our favorites in the U.S. and Canada is available on the PIAF Forum. Of course, there also are providers that offer all-you-can-eat calling plans. Two of our favorites are Vestalink and Future-Nine.

You’ll also need a softphone or SIP phone to actually place and receive calls. YATE makes a free softphone for PCs, Macs, and Linux machines so download your favorite and install it on your desktop.

Phones connect to extensions in FreePBX to work with Incredible PBX. Extensions talk to trunks (like Google Voice) to make and receive calls. FreePBX uses outbound routes to direct outgoing calls from extensions to trunks, and FreePBX uses inbound routes to route incoming calls from trunks to extensions to make your phones ring. In a nutshell, that’s how a PBX works.

There are lots of bells and whistles that you can explore down the road including voicemail, conferencing, IVRs, autoattendants, paging, intercoms, CallerID lookups, announcements, DISA, call parking and pickup, queues, ring groups, and on and on. And then there’s all of the Incredible PBX applications which are covered separately in this Nerd Vittles article. Once you’re comfortable with one server, you or your company will want some more. This Nerd Vittles article will walk you through interconnecting them into a seamless mesh network so that you can call from one office to another transparently. Yes, those articles were written for the Raspberry Pi. But the beauty of Incredible PBX is that it runs identically on virtually every server platform.

Here’s our 10-Step Checklist to Getting Started with FreePBX:

1. Setting Up Google Voice. If you want free calling in the U.S. and Canada, then you’ll need an existing Google Voice account that includes the Google Chat feature. You’ll need one dedicated to Incredible PBX, or it won’t work. Log out after setting up the new Google Voice account! Also note that Google Voice may cease to function at any time after May 15, 2014. You can read all about it here.

  • Log into existing Google Voice account
  • Enable Google Chat as Phone Destination
  • Configure Google Voice Calls Settings:
    • Call ScreeningOFF
    • Call PresentationOFF
    • Caller ID (In)Display Caller’s Number
    • Caller ID (Out)Don’t Change Anything
    • Do Not DisturbOFF
    • Call Options (Enable Recording)OFF
    • Global Spam FilteringON

  • Place test call in and out using GMail Call Phone
  • Log out of your Google Voice account

2. Activating a Google Voice Trunk. To create a Trunk in FreePBX to handle calls to and from Google Voice, you’ll need three pieces of information from the Google Voice account you set up above: the 10-digit Google Voice phone number, your Google Voice account name, and your Google Voice password. Choose Connectivity -> Google Voice (Motif) from the FreePBX GUI. The following form will appear:

Fill in the blanks with your information and check only the top 2 boxes. If your Google Voice account name ends in @gmail.com, leave that out. Otherwise, include the full email address. Then click Submit Changes and Apply Config.

There’s one more step or your Google Voice account won’t work reliably with Incredible PBX! From the Linux command prompt while logged into your server as root, restart Asterisk: amportal restart

3. Setting a Destination for Incoming Calls and Managing Faxes. Now that you’ve created your Google Voice Trunk, we need to tell FreePBX how to process inbound calls when someone dials your Google Voice number. There are any number of choices. You could simply ring an extension. Or you could ring multiple extensions by first creating a Ring Group which is just a list of extension numbers. Or you could direct incoming calls to an Interactive Voice Response (IVR) system. By default, Incredible PBX is configured to route all incoming calls to extension 701. You can change the setting whenever you like by choosing Connectivity -> Inbound Routes -> Default. In the Set Destination section of the form, change the target destination from the pull-down lists.

If you want your default inbound route to also handle incoming faxes, then go to the Fax Detect section of the Default inbound route. Change Detect Faxes to Yes. Change Fax Detection Type to SIP. Leave the Detection Time setting at 4. And change the Fax Destination to Custom Destinations: Fax (Hylafax). To Send Faxes, open AvantFax in FreePBX’s Other pulldown menu.

Always click Submit and then click Apply Config to save new settings in FreePBX.

4. Activating a Smartphone Trunk Using Bluetooth. One of the more exotic features of Incredible PBX on the CuBox platform is the ability to add your smartphone as an Asterisk trunk using Bluetooth. We’ve written a short recipe to get things working. So have a look at our Bluetooth tutorial and see if you’re up for the challenge. Moral of the story: the newer the cellphone, the better.

The LG G3 is the best of the lot, at least of the numerous cellphones we tested. Even better is an LG G3 paired with StraightTalk’s (AT&T-hosted) unlimited talk, text, and data plan for $45 a month. With Samsung smartphones older than a Galaxy S4, don’t waste your time. Ditto with Apple iPhones other than perhaps the very latest. Our iPhone 4S failed miserably. We gave up on Apple phones after that. Someday I’ll test my daughter’s 5c and report back.

5. Activating Additional Trunks with FreePBX. As we mentioned, there are lots of SIP providers to choose from. Once you have signed up for service, configuring the trunk is easy. Here is a quick Cheat Sheet courtesy of Kristian Hare, who translated our original setups into a spreadsheet. Just click on the image below to open it in a new window. Then click on the redisplayed image to enlarge it. The left and right cursor keys will move you around in the image. Click on the image again to shrink it.

6. Changing Extension Passwords. From the main FreePBX GUI, choose Applications -> Extensions. Then click on 701 in the Extension List on the right side of your display. You’ll see a form that looks like this:

For now, we only need to make a few changes. First, you need a very secure password for both the extension itself and your voicemail account for this extension. The extension secret needs to be a combination of letters and numbers. The Voicemail Password needs to be all numbers, preferably six or more. Replace the existing password entries with your own (very secure) entries. You also need to lock down this extension so that it is only accessible from devices on your private LAN. You do that with the deny and permit entries which currently are filled with zeroes. Leave the deny entry the way it is which tells Incredible PBX to block everybody except those allowed in the permit entry below. For the permit, we need the first three octets of your private LAN address, e.g. if your LAN is 192.168.0.something then the permit entry will be 192.168.0.0/255.255.255.0.

Finally, you need to plug in your actual email address in the Voicemail section so that voicemails can be delivered to you when someone leaves a message. You can also include a pager email address if you want a text message alert with incoming voicemails. If you want the voicemails to automatically be deleted from the server after they are emailed to you (a good idea considering the disk storage limitations of your microSD card), change the Delete Voicemail option from No to Yes. That’s it. Now save your settings by clicking the Submit button. Then reload the dialplan by clicking on the red prompt when it appears.

In case you’re curious, unless you’ve chosen to automatically delete voicemails after emailing them, you can retrieve your voicemails by dialing *98701 from any extension on your phone system. You’ll be prompted to enter the voicemail password you set up. In addition to managing your voicemails, you’ll also be given the opportunity to either return the call to the number of the person that called or to transfer the voicemail to another extension’s voicemail box. And you can always leave a voicemail for someone by dialing their extension number preceded by an asterisk, e.g. *701 would let someone leave you a voicemail without actually calling you.

7. Eliminating Audio and DTMF Problems. You can avoid one-way audio on calls and touchtones that don’t work with these simple settings in FreePBX: Settings -> Asterisk SIP Settings. Just plug in your public IP address and your private IP subnet. Then set ULAW as the only Audio Codec.

8. Configuring Your YATE Softphone. As we mentioned, the easiest way to get started with Incredible PBX is to set up a free YATE softphone on your Desktop computer. Versions are available at no cost for Macs, PCs, and Linux machines. Just download the appropriate one and install it from this link. Once installed, it’s a simple matter to plug in your extension 701 credentials and start making calls. Run the application and choose Settings -> Accounts and click the New button. Fill in the blanks using the IP address of Incredible PBX, 701 for your account name, and whatever password you created for the extension. Click OK.

Once you are registered to extension 701, close the Account window. Then click on YATE’s Telephony Tab and place your first call. It’s that easy!

9. Configuring CallerID Superfecta. In order to match names with phone numbers, Incredible PBX includes a FreePBX application named CallerID Superfecta. Out of the box, Incredible PBX will work fine if you remember to activate CallerID Superfecta whenever you create a new Inbound Route. The CNAM entries also will be displayed in your CDR reports. For those not in the United States, you may prefer to use a lookup source for your numbers other than the ones preconfigured in CallerID Superfecta. You will find all of the available modules on the POSSA GitHub site. Just download the ones desired into /var/www/html/admin/superfecta/sources and then activate the desired sources in Admin -> CID Superfecta -> Default. You can test your results and the performance using the Debug facility that’s built into the module.

10. Adding Speech Recognition for Incredible Applications. We used to include Google’s Speech-to-Text service in Incredible PBX builds. Unfortunately, Google has changed the rules a bit. Assuming your server still meets the “personal and development” standard, you can obtain an API key from Google and reactivate speech-to-text functionality for many of the Incredible PBX applications including Weather Reports by City (949), AsteriDex Voice Dialing by Name (411), SMS Dictator (767), and Wolfram Alpha for Asterisk (4747). To activate the STT service, just complete the steps in our tutorial. Then sign up for a Wolfram Alpha App ID (tutorial here), and run the following install scripts:

/root/wolfram/wolframalpha-oneclick.sh
/root/smsdictator/sms-dictator.sh

Enabling SAMBA Windows Networking with Ubuntu

It only takes a minute to enable SAMBA Windows Networking on your CuBox. We’ve reproduced our quick tutorial to show you how. Just follow the steps below to interconnect Incredible PBX with all the other computers on your LAN.

apt-get -y install samba samba-common python-glade2 system-config-samba
cd /etc/samba
mv smb.conf smb.orig.conf
wget http://incrediblepbx.com/samba-ubuntu.tar.gz
tar zxvf samba-ubuntu.tar.gz
rm *.tar.gz
sed -i '/# End of Trusted Provider Section/r '/etc/samba/smb.iptables'' /etc/iptables/rules.v4
iptables-restart
service smbd restart
service nmbd restart
sed -i 's|/usr/local/sbin/amportal restart|service smbd restart\nservice nmbd restart\n/usr/local/sbin/amportal restart|' /etc/rc.local
# set up root password for SAMBA access with full RW privileges
smbpasswd -a root

Incredible Backup and Restore

Once you have everything configured, it’s time to take a snapshot of your system and store it in a safe place. The new Incredible Backup lets you do that. From the Linux CLI, login as root and run: /root/incrediblebackup. The backup image will be saved to the /tmp folder and can be copied to a different server easily. To restore the backup to another system, you simply bring the other system up to the same version of Asterisk (11) and FreePBX (2.11), and then run /root/incrediblerestore with your backed up image. It’s the cheapest insurance you can buy! For detailed instructions on restoring backups, see this thread on the PIAF Forum.


Don’t forget to List Yourself in Directory Assistance so everyone can find you by dialing 411. And add your new number to the Do Not Call Registry to block telemarketing calls. Or just call 888-382-1222 from your new number.

Twofer Tuesday: Incredible PBX for RasPBX on BeagleBone Black and Raspberry Pi


We never were big fans of unfinished projects. And with Festivus behind us and Christmas tomorrow, it seemed only fitting to celebrate with a Twofer Tuesday Encore. Whether you like ‘em or hate ‘em, Google’s free text-to-speech engine is a big deal. It’s as close to perfect as any commercial product you can buy. So getting it to work with the BeagleBone® Black was really important for those of us that believe the BeagleBone Black is a near perfect telephony platform for home users and SOHO businesses. With this week’s release of Incredible PBX™ 4.11.3 for the RasPBX™, the GoogleTTS engine finally is available in all its glory on both the Raspberry Pi® and BeagleBone Black platforms. At $45 and sporting a “Made in the USA” moniker, the BeagleBone’s only real competition is the Raspberry Pi which has roughly a third the performance for VoIP-related tasks. Finding a BeagleBone Black has not been the easiest thing to accomplish either. They have sprung up five or six times over the past two weeks only to be snarfed up in a couple of hours. We have a PIAF Forum thread that will keep you apprised of the latest sightings or just follow us on Twitter. As with the early days of the Raspberry Pi, price gouging is alive and well so we’ll leave it to you to decide what your budget can tolerate. Our recommendation is hold your nose and pay the extra $15. The BeagleBone Black is worth it!

There’s more Black news this week as well. PIAF-Black™ now ushers in the next generation of Asterisk® with the official release of Asterisk 12.0.0. You can download the latest 32-bit or 64-bit PIAF™ ISOs from SourceForge. Then pick your favorite flavor of Asterisk to install. It’s that easy! New torrents were released this week as well thanks to our good friend, Isaac McDonald. Torrents are available for the latest PIAF 2.0.6.5.0 ISOs as well as two virtual machine builds for PIAF-Green™ with FreePBX™ 2.11 and Incredible PBX 11. Just visit the PIAF web site to grab your favorite torrent. Merry Christmas everybody!

For long time Nerd Vittles readers, you may recall that we built the original Incredible PBX™ for Raspberry Pi® (aka Incredible Pi) using much of the development platform pioneered by Gernot Bauer of RasPBX™ fame. In the early days of Gernot’s project, we just couldn’t get the necessary pieces in place on his platform to support Incredible PBX so we temporarily forked his terrific work in order to get Incredible Pi out the door quickly. That was then, and this is now as they say. RasPBX has grown in popularity because of the untiring efforts of Gernot & Co. in continually improving the platform. And six months ago, RasPBX was ported to the BeagleBone Black. Don’t be misled by its tiny footprint. The BeagleBone Black1 provides nearly triple the performance of a $35 Raspberry Pi for an extra $10 to $25 hardware investment depending upon where you buy the board. The rainbow case is a few cents more. :wink:

Let us cut to the chase. Run, don’t walk, to buy a BeagleBone Black! It’s that good. If Amazon is sold out, here is a link to other suppliers. See also this thread on the PIAF Forum for the latest availability news. In terms of performance, we would be hard-pressed to distinguish the BeagleBone Black’s performance from an identical Asterisk® and FreePBX®-based system running on the Intel® Atom® platform. The performance boost is that dramatic. So a few weeks ago we decided to take another look at the RasPBX platforms with the goal of porting Incredible PBX in much the same way that we currently provide the add-on for PBX in a Flash™ builds. The advantage for us is that it gets us out of the hardware business and lets us concentrate on building better VoIP application software. The advantage for you is it gives you additional choices, and they’re all still free!


UPDATE: Good News and More Good News. Everything covered below works flawlessly on the Raspberry Pi and BeagleBone Black platforms. On the Beaglebone Black hardware, everything works except GoogleTTS, and our friend, Lefteris Zafiris, will have a fix soon. GoogleTTS goes through the motions of converting text to speech, but the output is a constant high-pitched beep. For the short term, on the BeagleBone Black, we’ve substituted Flite for GoogleTTS until there is a fix. Soon with a little luck! We’ve also added an experimental IPtables Firewall WhiteList to the BeagleBone Black platform. Please read this thread on the PIAF Forum for details and keep us apprised of your progress. The complexity of the GoogleTTS fix for the BeagleBone Black made it an unsuitable candidate for the automatic update utility. Our apologies. We’ve set up a demo IVR application so you can check out the performance of Incredible PBX on the BeagleBone Black for yourself.

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)

Overview of Incredible PBX for RasPBX. Let’s quickly run down the new feature set for Incredible PBX 4.11.3 on the RasPBX platform. With the demise of Google Voice less than six months away, we thought it was important to begin offering some additional choices. With this build, you’ll have a dozen preconfigured VoIP trunks from the best providers in the business to choose from. Most offer outbound calls in the U.S. and Canada for a penny or less per minute. And many offer DID trunks with unlimited inbound calls for under $5 a month. Several offer free SIP URIs, or free U.S. DIDs, or free iNum DIDs for unlimited free calling worldwide. You’ll find lots of tips and suggestions in the Providers section of the PIAF™ Forum. Once you’ve signed up with one or more providers, all you have to do is plug in your credentials and enable the desired trunks in FreePBX. It only takes a few seconds.

We also wanted to provide a robust collection of Asterisk applications that let you bring up a fully-functional, feature-rich VoIP platform in a matter of minutes. As with all Incredible PBX builds, this release activates the Flite text-to-speech engine as well as Google’s TTS and STT interfaces. The Baker’s Dozen VoIP applications we’ve chosen for this initial release include free CallerID Name lookups for incoming calls, Voice Dialing with speech-to-text (STT) capability as well as Speed Dials, Yahoo News and Weather reports with text-to-speech (TTS) translation of the Yahoo news feeds, Weather Reports by ZIP code from the National Weather Service, MeetMe conferencing by simply dialing an extension, Telephone Reminders and Hotel-Style Wakeup Calls (both accessible by phone or via FreePBX GUI), Today in History, SMS messaging, Wolfram Alpha, and our versatile AsteriDex contacts database. We’ve also integrated the Incredible PBX automatic update service into the RasPBX build. Just log into your server once in a while, and the rest is automagic. You also get email delivery of voicemails in MP3 format so that you can play back your messages with almost any email client. Finally, there’s a new status application to tell you everything you want to know about your RasPBX server in a single screen.

Getting Started. Incredible PBX for RasPBX is basically a scripted installer. It assumes you already have a functioning RasPBX device. The only gotcha is your RasPBX system needs to be freshly created with no customization. This is important because, as part of the installation procedure, Incredible PBX loads a 15MB image snapshot that overwrites all of your Asterisk, FreePBX, and MySQL configurations. If you have previously customized your setup or added features such as faxing, those will get wiped out during the Incredible PBX installation process. Bottom Line: Start by creating a new RasPBX SD image for use with Incredible PBX. Boot RasPBX and log in as root. Download and run the Incredible PBX installer. Once the Incredible PBX install is complete, customize your new system as desired. While nothing is 100% bullet-proof, we’ve taken pains to design Incredible PBX in such a way that it can coexist with future updates to RasPBX deployed through the raspbx-upgrade utility. And Incredible PBX has its own update utility, update-my-raspbx, which is run automatically when you log into your server as root. Finally, we are confident that this new Incredible PBX release is stable; however, it is version 1.0 software and should be treated as such at least through the end of 2013. Please report any bugs you discover on the PIAF Forum, and we will attempt to provide timely fixes.

Installing Incredible PBX. As noted, we’re assuming you already have created a fresh SD card with your RasPBX image. If not, start with the first four steps only of the excellent tutorials for the Raspberry Pi or BeagleBone Black. Next, boot your system from the SD card and log in with username root and password raspberry or beaglebone depending upon your hardware platform. Be sure you have a working Internet connection for your hardware. Then proceed with the Incredible PBX installation procedure below:

cd /
wget http://incrediblepbx.com/incrediblepbx11-raspbx.gz
gunzip incrediblepbx11-raspbx.gz
chmod +x incrediblepbx11-raspbx
./incrediblepbx11-raspbx

Hang around for the first couple minutes of the install. You’ll be prompted to type a Y as part of the raspbx-upgrade procedure. Once you get past that prompt, you can go have a cup of coffee while the installation procedure continues. It takes about 15-30 minutes to complete depending upon the speed of your Internet connection. Once the base install finishes, the update-passwords script will be launched. It’s imperative that you reset all of your passwords with very secure passwords immediately. This includes the root password, the FreePBX and ARI admin passwords, the extension 701 password, the extension 701 voicemail password, the email delivery address for extension 701, and the telephone reminders password for scheduling reminders by phone. Just fill in the blanks, and the script will do the heavy lifting.

Asterisk Security. Once the Incredible PBX install completes, what you still have is an Incredibly Insecure PBX. Unless you’ve already done so, make certain that Incredible PBX is repositioned behind a hardware-based firewall with no Internet port exposure! This is very important. Neither Asterisk nor FreePBX was designed for direct exposure to the Internet. Before you do anything else, read our Primer on Asterisk Security. Remember, it’s your phone bill.

UPDATE: Travelin’ Man 3 Now Implemented. Beginning with Incredible PBX 4.11.3, IPtables WhiteList security was added to the RasPBX BeagleBone Black platform. And version 4.11.4 released on 1-4-14 added it to the Raspberry Pi edition of RasPBX as well. For the nuts and bolts of how the IPtables firewall and WhiteLists work, read the Travelin’ Man 3 tutorial. Do NOT install the application! It’s already there. We still recommend that you always run your server behind a hardware-based firewall. Travelin’ Man 3 just adds an extra layer of protection. Think of it as a second condom without the pain. :wink:

As initially configured, IPtables is set up to allow all incoming and outgoing traffic. It will display as DN in the status display. You have a couple of options. If you only want to allow incoming traffic from phones and users on your private LAN while permitting registered SIP and IAX trunk connections from anywhere, then log into your server as root and execute this command:

cp /root/iptables.lanonly /etc/network/iptables

If you want to further lock down your server and manage all external connections from outside your LAN, run: /root/secure-iptables. As configured, IPtables never blocks internal LAN traffic. By running secure-iptables, you get to set one “safe” external IP address for access to your server in addition to automatically configuring the safe IP addresses of a dozen SIP providers. You then can add additional IP addresses to your WhiteList by running /root/add-ip or /root/add-fqdn. You can delete providers with /root/del-acct. Check the status of your IPtables setup at any time with this command: iptables-status. Restart/reload IPtables settings using only this command: iptables-restart. If you use the traditional IPtables reload procedure, you will permanently erase any fully-qualified domain names in your IPtables configuration and convert them (permanently) to IP addresses. Don’t do it! Always use iptables-restart. Never erase files in /root with the .iptables extension. This is how Travelin’ Man 3 keeps track of your WhiteList entries so that you can delete as desired. For further details, read the Travelin’ Man 3 article.

Overclocking the Raspberry Pi. On the Raspberry Pi platform only, to enable overclocking at your own risk, run: raspi-config. Overclocking works for us. YMMV! The key is a good power supply. Even though the kernel now monitors CPU temperature and manages overclocking, it’s always nice to see for yourself. To monitor the CPU temperature, just run the status program which provides a current snapshot anytime.

Resizing an SD Card. On both the BeagleBone Black and Raspberry Pi platforms, you can resize (expand) the default partition to accommodate a larger SD card. On the Raspberry Pi, the default partition is 4GB. On the BeagleBone Black, it’s only 2GB. To resize the partition to make use of a larger SD card on a Raspberry Pi, choose the resize option after running raspi-config. Then reboot. The BeagleBone Black is a different beast. While we don’t recommend it, you can actually run Incredible PBX using the internal 2GB eMMC memory board rather than an external Micro SD card. Gernot’s documentation will walk you through how to do it. While it is screaming fast compared to an SD card, you’ll only have 371MB of breathing room so it means constant monitoring of your log files and minimal use of functions that consume disk space. Or you could create a cron job to run daily and use a script like ours:
#!/bin/bash
cd /var/log/asterisk
touch empty.log
chmod 664 empty.log
chown asterisk:asterisk empty.log
cp empty.log freepbx_dbug
cp empty.log freepbx_debug
cp empty.log freepbx.log
cp empty.log full
cd ..
rm *.0*
rm *.1*
rm /tmp/ggl*

We much prefer at least an 8GB Type 4 SD card for Incredible PBX. On the BeagleBone Black, we’ve added the resize-partition script in the /root folder. Just run it after booting from your Micro SD card.

Setting Up Google Voice. If you want free calling in the U.S. and Canada for the next five months, then you’ll need a Google Voice account, and you’ll need one dedicated to Incredible PBX, or it won’t work. Log out after setting up the new Google Voice account! Also note that Google Voice will cease to function on May 15, 2014. Read all about it here.

  • Register for Google Voice account (no funky characters in your password!)
  • Enable Google Chat as Phone Destination
  • Configure Google Voice Calls Settings:
    • Call ScreeningOFF
    • Call PresentationOFF
    • Caller ID (In)Display Caller’s Number
    • Caller ID (Out)Don’t Change Anything
    • Do Not DisturbOFF
    • Call Options (Enable Recording)OFF
    • Global Spam FilteringON

  • Place test call in and out using GMail Call Phone

Accessing Incredible PBX By GUI. You don’t have to be a Linux guru to use Incredible PBX. In fact, we’re just about finished with the Linux command prompt, but stay logged in until we finish a few more steps below. Most of your configuration of Incredible PBX will be performed using the FreePBX Web GUI.

If you’re new to Asterisk and FreePBX, here’s the one paragraph primer on what needs to happen before you can make free calls with Google Voice. You’ll obviously need a free Google Voice account. This gets you a phone number for people to call you and a vehicle to place calls to plain old telephones throughout the U.S. and Canada at no cost. You’ll also need a softphone or SIP phone to actually place and receive calls. YATE makes a free softphone for PCs, Macs, and Linux machines so download your favorite and install it on your desktop. Phones connect to extensions in FreePBX to work with Incredible PBX. Extensions talk to trunks (like Google Voice) to make and receive calls. FreePBX uses outbound routes to direct outgoing calls from extensions to trunks, and FreePBX uses inbound routes to route incoming calls from trunks to extensions to make your phones ring. In a nutshell, that’s how a PBX works. There are lots of bells and whistles that you can explore down the road.

Let’s get started. Using a browser, enter the IP address of your server or just use http://raspbx.local as the address. Choose FreePBX Administration. When prompted for a username and password, use admin for the username and whatever FreePBX password you set up when you initially configured your server above. If you ever forget your credentials, just run /root/update-passwords again to reset them.

Changing FreePBX admin Password and Default Email. From the main FreePBX GUI, click Admin => Administrators. Click on admin user in the far-right column. Enter a new Password and click Submit Changes button. We did this in update-passwords, but now you’ll know how to do it from with the FreePBX GUI as well. Click Apply Config button. Be sure to set your default email address in the right margin of Admin -> Module Admin and save your entry. By doing this, you’ll get periodic notices of FreePBX updates. It’s a good idea to stay current with these. They are generally well tested before release.

Activating a Google Voice Trunk. To create a Trunk in FreePBX to handle calls to and from Google Voice, you’ll need three pieces of information from the Google Voice account you set up above: the 10-digit Google Voice phone number, your Google Voice account name, and your Google Voice password. Choose Connectivity -> Google Voice (Motif) from the FreePBX GUI. The following form will appear:

Fill in the blanks with your information and check only the top 2 boxes. If your Google Voice account name ends in @gmail.com, leave that out. Otherwise, include the full email address. Then click Submit Changes and Apply Config.

There’s one more step or your Google Voice account won’t work reliably with Incredible PBX! From the Linux command prompt while logged into your server as root, restart Asterisk: amportal restart

Setting a Destination for Incoming Calls. Now that you’ve created your Google Voice Trunk, we need to tell FreePBX how to process inbound calls when someone dials your Google Voice number. There are any number of choices. You could simply ring an extension such as 700 which we’ve already set up for you. Or you could ring multiple extensions by first creating a Ring Group which is just a list of extension numbers. Or you could direct incoming calls to an Interactive Voice Response (IVR) system.

By default, Incredible PBX is configured to route all incoming calls to extension 701. You can change this whenever you like by choosing Connectivity -> Inbound Routes -> Default. In the Set Destination section of the form, change the target to your desired destination for the incoming calls. Then click Submit and Apply Config.

Changing Extension Passwords. From the main FreePBX GUI, choose Applications -> Extensions. Then click on 701 in the Extension List on the right side of your display. You’ll see a form that looks like this:

We’ve already made these changes using update-passwords, but here’s how to do it in the FreePBX GUI. The extension secret needs to be a combination of letters and numbers. The Voicemail Password needs to be all numbers, preferably six or more. Replace the existing passwords with your own (very secure) entries. You also need to lock down this extension so that it is only accessible from devices on your private LAN. You do that with the deny and permit entries which currently are filled with zeroes. Leave the deny entry the way it is which tells Incredible PBX to block everybody except those allowed in the permit entry below. For the permit, we need the first three octets of your private LAN address, e.g. if your LAN is 192.168.0.something then the permit entry will be 192.168.0.0/255.255.255.0.

Finally, you need to insert your actual email address in the Voicemail section so that voicemails can be delivered to you when someone leaves a message. You can also include a pager email address if you want a text message alert with incoming voicemails. If you want the voicemails to automatically be deleted from the server after they are emailed to you (a good idea considering the disk storage limitations of an SDHC card), change the Delete Voicemail option from No to Yes. That’s it. Now save your settings by clicking the Submit button. Then reload the dialplan by clicking on the red prompt when it appears.

In case you’re curious, unless you’ve chosen to automatically delete voicemails after emailing them, you can retrieve your voicemails for extension 701 by dialing *98701 from any extension on your phone system. You’ll be prompted to enter the voicemail password you set up. And you can leave a voicemail for someone by dialing their extension number preceded by an asterisk, e.g. *701 would let someone leave you a voicemail without actually calling you.

Eliminating Audio and DTMF Problems. You can avoid one-way audio on calls and touchtones that don’t work with these simple settings in FreePBX: Settings -> Asterisk SIP Settings. Just plug in your public IP address and your private IP subnet. Then set ULAW as the only Audio Codec.

Setting Up a Desktop Softphone. Incredible PBX supports all kinds of telephones, but we’ll start with the easy (free) one today. You can move on to “real phones” once you’re smitten with the VoIP bug. For today, you’ll need to download a softphone to your desktop PC or Mac.

As we mentioned, the easiest way to get started with Incredible PBX is to set up a YATE softphone on your Desktop computer. Versions are available at no cost for Macs, PCs, and Linux machines. Just download the appropriate one and install it from this link. Once installed, it’s a simple matter to plug in your extension 701 credentials and start making calls. Run the application and choose Settings -> Accounts and click the New button. Fill in the blanks using the IP address of Incredible PBX, 701 for your account name, and whatever password you created for the extension. Click OK.

Once you are registered to extension 701, close the Account window. Then click on YATE’s Telephony Tab and place your first call. It’s that easy!

Incredible Trunks. When you’re ready to try some other SIP providers, we’ve done the hard work for you by providing the setups for a dozen terrific providers. All you have to do is sign up for service on their sites, enable the desired Trunks in FreePBX, and plug in your credentials. Here is a quick Cheat Sheet courtesy of Kristian Hare, who translated the Incredible PBX setups into a spreadsheet. Just click on the image below to open it in a new window. Then click on the redisplayed image to enlarge it.

Adding WiFi Support. This is covered on Gernot’s web site, but we’ll address it just for ease of reference. The most important detail is don’t get creative with your choice of USB WiFi adapters. The Edimax EW-7811Un works so use it. It’s about $10 from Amazon with free 2-day Prime shipping. Next, edit /etc/network/interfaces and add the following lines using the name of your WiFi network as well as your password “in quotes”:

auto wlan0
allow-hotplug wlan0
iface wlan0 inet dhcp
wpa-ssid your-ssid-here-no-quotes
wpa-psk "your-passphrase-here-with-quotes"

Next, reboot your server and login as root. Your USB WiFi adapter should be lit. Running ifconfig should display an IP address for wlan0. ifdown eth0 will shut down your wired connection. Then restart Asterisk to switch to WiFi: amportal restart.

Shutting Down Your Server. Last but not least, never just pull the plug when you want to shut down your server, or you may end up with corrupted MySQL databases. Then nothing will run. Instead, log into your server as root, and issue the following commands: amportal stop and then shutdown -h now.

The Incredible PBX 4.11.3 Software Collection

Now for the fun stuff. For most folks getting started with Asterisk and FreePBX, the steepest learning curve is moving from a functioning system to one that can actually do cool stuff. Text-to-speech and speech-to-text applications and IVRs and call management and conferencing and click to dial and SMS messaging and faxing are what separate the men from the boys on the Asterisk playing field. And that’s where Incredible PBX really shines. You don’t have to do anything but choose the apps you want to deploy for yourself or your users. Everything is already in place. If you don’t use it, it doesn’t consume any computing resources. So it’s not like the bloatware of decades ago that was always sitting in memory wasting your computing cycles. Here’s a quick thumbnail on each of the applications that’s included in Incredible PBX for RasPBX. You can include almost all of these applications in your IVRs so that callers can make a selection from a list of menu choices. We’ve included the appropriate FreePBX links below. On many of the apps, we’ve also included links to Nerd Vittles or PIAF Forum tutorials for more detailed documentation when you need it.

Bluetooth Proximity Detection

Finally, if you really want to impress your friends, buy yourself a cheap Bluetooth adapter and set up a Proximity Detection System that will forward your Asterisk calls to your cellphone when you’re away from your desk. This Nerd Vittles article will walk you through the quick setup process. Before you begin, just install bluez on your Raspberry Pi or BeagleBone Black: apt-get install bluez.

A Word About Flite TTS

We’ve included FLITE as the generic text-to-speech engine for Asterisk. The quality of Google TTS is much better, but we never know how long Google apps will continue to function. Because FLITE is actually integrated into Asterisk, it is susceptible to breakage if a RasPBX upgrade installs a new release of Asterisk. If this happens, you’ll know when FLITE goes silent. You can also run the following command from the Linux command prompt to check it. If you don’t get a page of FLITE information, it’s broken. :-)

asterisk -rx "core show application like flite"

Don’t fret if FLITE breaks. Here’s how to fix it:

cd /usr/src/flite
make clean
make
make install
amportal restart

A Word About MySQL

To eliminate the need to maintain separate versions of Incredible PBX for RasPBX on the Raspberry Pi and BeagleBone Black platforms, we’ve changed the MySQL password on both platforms to raspberry. Originally, beaglebone was the assigned password on the BeagleBone Black RasPBX implementation.

The 5-Minute PBX: Incredible PBX 11 and Incredible Fax Get a Facelift

With the release of PBX in a Flash™ 2.0.6.4.4 last week, it seemed only fitting to reintroduce our one-click wonder that takes advantage of the latest and greatest feature sets in both Asterisk® 11 and FreePBX® 2.11. Incredible PBX™ 11 gives you the best of all worlds plus all of the very best, preconfigured Asterisk applications we could find. And the installer together with all of the apps are pure open source so you can learn how to build a system like this for yourself if that happens to be your thing. Installation is a breeze. Set up a new PBX in a Flash™ 2.0.6.4.4 server with PIAF-Green and FreePBX 2.11, download the Incredible PBX 11 installer, and five minutes later you’re ready to begin your VoIP adventure. And it’s all FREE!
 

News Flash: Incredible PBX 11 and Incredible Fax also are available for the $35 Raspberry Pi.

So what’s included? Dozens of upgraded Asterisk Apps. 9-Layer Security. 20 Preconfigured VoIP Provider Trunks. 1-Click Installers for Asterisk.everything. Certified Asterisk support. All-new Google Voice connectivity with Asterisk Motif. Voice-enabled SMS messaging and script-based SMS message blasting. Incredible PBX Automatic Update Utility. Incredible Fax™ 11 delivers free faxing with HylaFax™ and AvantFax®. And Incredible PBX and Incredible Fax are now GPL2-licensed.

The Incredible PBX 11 Inventory. For those that have never heard of The Incredible PBX, here’s the current 11.0 feature set in addition to the base install of PBX in a Flash with the CentOS 6.4, Asterisk 11, FreePBX 2.11, and Apache, SendMail, MySQL, PHP, phpMyAdmin, IPtables Linux firewall, Fail2Ban, and WebMin. Incredible Fax, NeoRouter and PPTP VPNs, and all sorts of backup solutions are still just one command away and may be installed using the scripts included with Incredible PBX 11 and PBX in a Flash. Type help-pbx and browse /root for dozens of one-click install scripts.

And then there’s the Incredible Freebie! As they say, “Never look a gift horse in the mouth.” What began as a kludgey, dual-call, dual-provider Google Voice implementation to take advantage of Google’s free PSTN calling in the U.S. and Canada with Asterisk 1.4 and 1.6 is now a zippy-quick, Gtalk-based calling platform that rivals the best SIP-to-SIP calls on the planet. The Incredible PBX Google Voice implementation provides virtually instantaneous PSTN connections to almost anybody, anywhere. Trust us! Except for the price which is still free, you’ll never know you weren’t connected via Ma Bell’s overpriced long-distance lines and neither will the Little Mrs.

To get started, download the latest PBX in a Flash 2.0.6.4.4 ISO from SourceForge, burn to then boot from the PIAF2 CD, choose the PIAF-Green option to load Asterisk 11, and pick FreePBX 2.11 when prompted. Take a look at the PIAF Quick Start Guide for step-by-step installation instructions. Once the PIAF2 install is completed, just download and run the new Incredible PBX 11 installer.

A Few Words About Security. Thanks to its Zero Internet Footprint™ design, Incredible PBX is different. It remains the most secure Asterisk-based PBX around. What this means is The Incredible PBX has been engineered to sit safely behind a NAT-based, hardware firewall with no Internet port exposure to your actual server. For those needing remote telephone support, Incredible PBX optionally loads Travelin’ Man 2 and 3 for you so your IPtables Linux Firewall can be either self-managed by end-users or set up with predefined IP addresses and FQDNs for all of your remote sites. Read about this Asterisk SIP vulnerability. Then you’ll understand why WhiteList-based server security has become absolutely essential. WhiteList Security means only those devices with a registered IP address in your WhiteList can get to your server’s resources. To the NSA and everyone else, your server doesn’t even exist. Their only way to connect to you is with a POTS telephone and your published phone number. Can you hear me now?

For those with multiple servers to interconnect, we’ve provided one-click installers for not one but two VPN solutions: NeoRouter and PPTP. Suffice it to say, Incredible PBX has Security in Spades™: customized IPtables Linux Firewall, Fail2Ban tweaked for Asterisk security monitoring, FreePBX Extension Lockdown by IP address, randomized FreePBX extension passwords, Travelin’ Man 2 and 3 WhiteList Security, multiple VPN solutions for encrypted server-to-server communications, plus a bottom-up design focused on flawless operation behind a hardware-based firewall. You won’t find a more secure Personal Branch Exchange™ at any price.

Here’s the Incredible PBX 9-Layer Security Model:

Prerequisites. Here’s what we recommend to get started properly:

We’ve shifted gears on our recommended Atom platform for PIAF2 after excellent results with both the single-core and dual-core Atom kits manufactured by Foxconn (pictured on the left below). That’s the dLink Gaming Router on the right. Seems kinda silly to spend twice as much for a machine that you can build yourself in under 5 minutes. Basically you remove four screws, insert a Phillips screwdriver in one of the holes and gently pry the cover away from the box. Then you pop off the back by inserting a small flat-blade screwdriver, remove four more screws, slide in a solid-state drive (SSD) and a 4GB stick of notebook computer RAM, and you’re done in a couple minutes. Replace the screws and the cover, and you have a perfect PIAF2 platform with terrific performance and no moving parts for about $200. The link above will take you to the PIAF Forum thread for these machines. They go on sale almost weekly. See the right column of Nerd Vittles (just below our tweets) for this week’s special at Amazon. The dual-core Atom box typically is under $150. It could easily handle an office with 50+ employees sitting on a bookshelf with an Internet connection (wired or wireless!). No noise. Very little heat. Low power requirements. Perfect!

Installing Incredible PBX 11. The installation process is simple. Here are the 3 Easy Steps to Free Calling, and The Incredible PBX will be ready to receive and make free U.S./Canada calls immediately:

1. Install PIAF-Green with FreePBX 2.11 using PIAF2 ISO or PIAF-Green VM
2. Run Incredible PBX 11 installer
3. Configure Google Voice and a softphone or SIP phone

Configuring Google Voice. If you plan to use Google Voice, you’ll need a dedicated Google Voice account to support Incredible PBX 11. If you want to use the inbound fax capabilities of Incredible Fax 11, then you’ll need an additional Google Voice line that can be routed to the FAX custom destination using FreePBX. 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!

We’ve tested this extensively using an existing Gmail account, and inbound calling is just not reliable. The reason seems to be that Google always chooses Gmail chat as the inbound call destination if there are multiple registrations from the same IP address. So, be reasonable. Do it our way! Set up a dedicated Gmail and Google Voice account, and use it exclusively with Incredible PBX 11. It’s free at least through 2013. Google Voice no longer is by invitation only so, if you’re in the U.S. or have a friend that is, head over to the Google Voice site and register.

You must choose a telephone number (aka DID) for your new account, or Google Voice calling will not work… in either direction. Google used to permit outbound Gtalk calls using a fake CallerID, but that obviously led to abuse so it’s over! You also have to tie your Google Voice account to at least one working phone number as part of the initial setup process. Your cellphone number will work just fine. Don’t skip this step either. Just enter the provided 2-digit confirmation code when you tell Google to place the test call to the phone number you entered. Once the number is registered, you can disable it if you’d like in Settings, Voice Setting, Phones. But…

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 don’t see this option, you may need to call up Gmail and enable Google Chat there first. Then go back to the Google Voice Settings.

While you’re still in Google Voice Settings, click on the Calls tab. Make sure your settings match these:

  • Call ScreeningOFF
  • Call PresentationOFF
  • Caller ID (In)Display Caller’s Number
  • Caller ID (Out)Don’t Change Anything
  • Do Not DisturbOFF
  • Call Options (Enable Recording)OFF
  • Global Spam FilteringON

Click Save Changes once you adjust 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.

Incredible PBX 11 Installation. Log into your server as root and issue the following commands to run The Incredible PBX 4 installer:

cd /root
wget http://incrediblepbx.com/incrediblepbx11.gz
gunzip incrediblepbx11.gz
chmod +x incrediblepbx11
./incrediblepbx11

Now have a quick cup of coffee while the installer works its magic. While you’re waiting just make sure that you’ve heeded our advice and installed your server behind a hardware-based firewall. No ports need to be opened on your firewall to support Incredible PBX. Leave it that way!

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!


FINAL STEPS. Once the Incredible PBX 11 install completes, there are two optional steps for those that will have remote phones or users outside your firewall. Install both Travelin’ Man 2 and 3 for an ultra-secure system.

Logging in to FreePBX 2.11. Using a web browser, you access the FreePBX GUI by pointing your browser to the IP address of Incredible PBX 11. Click on the Users tab. It will change to Admin. Now click the FreePBX Admin button. When prompted for a username, it’s maint. When prompted for the password, it’s whatever you set up as your maint password when you installed PBX in a Flash. If you forget it, you can always reset it by logging into your server as root and running passwd-master.

Configuring Google Voice Trunks in FreePBX. All trunk configurations now are managed within FreePBX, including Google Voice. This makes it easy to customize your Incredible PBX to meet your specific needs. If you plan to use Google Voice, here’s how to quickly configure one or more Google Voice trunks within FreePBX. After logging into FreePBX with your browser, click the Connectivity tab and choose Google Voice/Motif. To Add a new Google Voice account, just fill out the form. Do NOT check the third box or incoming calls will never ring!

While you’re still in FreePBX, choose Applications, Extensions, and click on the 701 extension. Write down your extension and voicemail passwords. You’ll need them to configure a phone in a minute.

IMPORTANT LAST STEP: Google Voice will not work unless you restart Asterisk from the Linux command line at this juncture. Using SSH, log into your server as root and issue the following command: amportal restart.

Incredible Fax 11 Installation. If you want the added convenience of having your Incredible PBX double as a free fax machine, run /root/incrediblefax11.sh after the Incredible PBX 4 install completes. Plug in your email address for delivery of incoming faxes and enter your home area code when prompted. For every other prompt, just press the Enter key. If you’d like to also add the optional OCR utility, just choose it when prompted. For complete documentation, see this Nerd Vittles article. Don’t forget that a REBOOT OF YOUR SERVER is required when the install is finished, or faxing won’t work! Then log in through the PIAF GUI using maint:password. You’ll find the AvantFax GUI on the Admin menu.

Also be sure to set up a second, dedicated Google Voice number if you want support for inbound faxing. Once the Google Voice credentials are configured in FreePBX for the additional Google Voice line, simply add an Inbound Route for this DID to point to the Custom Destination: Fax (Hylafax). This comes preconfigured with Incredible PBX 11.

Eliminating Audio and DTMF Problems. You can avoid one-way audio on calls and touchtones that don’t work with these simple settings in FreePBX: Settings -> Asterisk SIP Settings. Just plug in your public IP address and your private IP subnet. Then set ULAW as the only Audio Codec.

Setting Up a Desktop Softphone. PBX in a Flash supports all kinds of telephones, but we’ll start with the easy (free) one today. You can move on to “real phones” once you’re smitten with the VoIP bug. For today, you’ll need to download a softphone to your desktop PC or Mac.

The easiest way to get started is to set up a YATE softphone on your Desktop computer. Versions are available at no cost for Macs, PCs, and Linux machines. Just download the appropriate one and install it from this link. Once installed, it’s a simple matter to plug in your extension credentials and start making calls. Run the application and choose Settings -> Accounts and click the New button. Fill in the blanks using the IP address of your server, 201 for your account name, and whatever password you created for the extension. Click OK.

Once you are registered to extension 701, close the Account window. Then click on YATE’s Telephony Tab and place your first call. It’s that easy!

Incredible PBX Test Flight. The proof is in the pudding as they say. So let’s try two simple tests. First, let’s place an outbound call. Using the softphone, dial your 10-digit cellphone number. Google Voice should transparently connect you. Answer the call and make sure you can send and receive voice on both phones. Second, from another phone, call the Google Voice number that you’ve dedicated to The Incredible PBX. Your softphone should begin ringing shortly. The call will be answered by the Nerd Vittles sample IVR. You can explore all of the preconfigured options at your leisure.

Learn First. Explore Second. Even though the installation process has been completed, we strongly recommend you do some reading before you begin your VoIP adventure. VoIP PBX systems have become a favorite target of the hackers and crackers around the world and, unless you have an unlimited bank account, you need to take some time learning where the minefields are in today’s VoIP world. Start by reading our Primer on Asterisk Security. We’ve secured all of your passwords except your root password and your passwd-master password. We’re assuming you’ve put very secure passwords on those accounts as if your phone bill depended upon it. It does! There’s loads of additional documentation on the PBX in a Flash documentation web site.

Incredible PBX 11 Automatic Update Utility. With Incredible PBX 11, we’ve introduced a new automatic update utility to assist in keeping your system current and secure. It runs each time you log into your server as root. The first ten updates are at no cost. You then can elect to continue the service by subscribing to the update service which is available for a modest $20 for the remainder of calendar year 2013. Whether you subscribe or not, new releases of PBX in a Flash and Incredible PBX will always be free! This simply is a way for us to recover our costs in providing a service that many of our users have asked for. We hope you like it.

Choosing VoIP Providers. Nothing beats free when it comes to long distance calls. But nothing lasts forever. And, in the VoIP World, redundancy is dirt cheap. So we strongly recommend you set up another account with Vitelity using our special link below. This gives your PBX a secondary way to communicate with every telephone in the world, and it also gets you a second real phone number for your new system… so that people can call you. Here’s how it works. You pay Vitelity a deposit for phone service. They then will bill you $3.99 a month for your new phone number. This $3.99 also covers the cost of unlimited inbound calls (two at a time) delivered to your PBX for the month. For outbound calls, you pay by the minute and the cost is determined by where you’re calling. If you’re in the U.S., outbound calls to anywhere in the U.S. are a little over a penny a minute. If you change your mind about Vitelity and want a refund of the balance in your account, all you have to do is ask. The trunks for Vitelity already are preconfigured with The Incredible PBX. Just insert your credentials using FreePBX and uncheck the Disable Trunk checkbox. Then add the Vitelity trunk as the third destination for your default outbound route. That’s it. Congratulations! You now have a totally redundant phone system.

Incredible PBX 11 includes preconfigured trunk setups for all of your favorite trunk providers. Just plug in your credentials and activate the trunks you need. In less than a minute, you’re done. Here’s the Incredible PBX Top 20 Trunk List with some reasons why these providers made our short list:

  • AxVoice ($14.99/mo. Business Plan; $16.58/mo. Unlimited Calls to 45 Countries)
  • CallCentric (Good International Calling Rates)
  • DIDforSale (20 channels per DID; unlimited DID calls for $8.99/mo.)

Configuring Email. You’re going to want to be notified when updates are available for FreePBX, and you may also want notifications when new voicemails arrive. Everything already is set up for you except actually entering your email notification address. Using a web browser, open the FreePBX GUI by pointing your browser to the IP address of your Incredible PBX. Then click Administration and choose FreePBX. To set your email address for FreePBX updates, go to Admin -> Module Admin and click on the shield on the right margin. To configure emails to notify you of incoming voicemails, go to Applications -> Extensions -> 701 and scroll to the bottom of the screen. Then follow your nose. Be sure to reload FreePBX when prompted after saving your changes.

A Final Word About Security. In case you couldn’t tell, security matters to us, and it should matter to you. Not only is the safety of your system at stake but also your wallet and the safety of other folks’ systems. Unless you subscribe to the new Automatic Update Utility, our only means of alerting you to security issues which arise is through the RSS Feed that we maintain for the PBX in a Flash project. This feed is prominently displayed in the web GUI which you can access with any browser pointed to the IP address of your server. Check It Daily! Or add our RSS Feed to your favorite RSS Reader. We also recommend you follow @NerdUno on Twitter. We’ll keep you entertained and provide immediate notification of security problems that we hear about. Finally, visit the PIAF Forums regularly. You’ll be surprised what you can learn in 10 minutes of browsing. Be safe!

Here We Go Again: Getting Ready for the Next Google Voice Train Wreck


Self-inflicted wounds are nothing new in the technology business, but Google spent much of last week working hard to take top honors for what is clearly one of the most selfish and short-sighted moves ever in the telecommunications marketplace. Less than a week after extolling the values of open source technology during Google I/O 20131, Google wasted little time performing a complete 180 by deep sixing further support of the open source XMPP protocol for messaging and VoIP communications. With one brief announcement, Google basically killed off years of Google Voice development and announced the upcoming demise of Google Voice, XMPP, and Jabber messaging as we know it. Never mind that literally millions of users have come to rely upon Google Voice and XMPP messaging as their primary sources of communications. Google now has declared XMPP too confining for their view of what the telecommunications world really needs. Instead, we get yet another proprietary communications protocol. So much for the Do No Evil ethos. With classic pot calling the kettle black ire, one of Microsoft’s leading cheerleaders wasted little time condemning the move.

So why the sudden change of heart at Google? Well, it had nothing to do with the needs of Google customers obviously. In the old days, Google at least labeled projects as beta (for years) to warn you that something might happen down the road, good or bad. That era is over. Now the carnage happens almost randomly. Remember Google knols? It was perhaps the greatest collection of medical and technical literature of all time. Poof! All gone. We won’t go through the entire litany. Suffice it to say, this is nothing new for Google. Every company is entitled to its New Coke moment. Google has had more than its fair share, and it should serve as a wakeup call to organizations and individuals that reliance upon Google infrastructure is a really bad idea.

The current train wreck turns out to be yet another turf war motivated by retribution against Microsoft’s recent decision to support XMPP in its Outlook.com unified messaging product, something most companies would have greeted with jubilation. Instead, Google is miffed that Microsoft was now supporting its messaging protocol while continuing to keep its own protocol proprietary. That meant Microsoft cellphones could chat with Android phones but not the other way around. The moral of the story for consumers is pretty simple. Don’t for a minute assume that any technology company has your best interests at heart. None of them do. It’s all about money and industry domination. Google viewed this as a brazen attempt by Microsoft to create a messaging platform that could speak Android while continuing to restrict access to the Microsoft messaging installed base. And Google chose to pick up its marbles and go home rather than hand Microsoft easy access to hundreds of millions of Android cellphone users. So we’re back to handing the Bell Sisters the unified messaging monopoly with SMS and MMS as the lowest common denominator. Welcome to Big Business!

What does all of this have to do with Google Voice? Well, it rides along on the same messaging platform as Google Talk, Microsoft Lync, and XMPP/Jabber-based solutions including Asterisk, FreeSwitch, Yate, Cisco Jabber, Openfire, and Avaya in addition to all of the Google Voice-compatible softphones and OBiHai devices. So expect a train wreck!

We’re all about VoIP communications so we’ll leave the cellphone messaging for others to sort out. The important question for those of us that depend upon Google Voice for VoIP communications is what can you do to insulate yourself from the upcoming disaster. You can bury your head in the sand and pretend this isn’t going to happen, and you’d be dead wrong for the reasons we’ve outlined above. And, remember, Google has served clear notice that XMPP is over as far as they are concerned unless Microsoft, Apple, and now Facebook blink. Of course, Google could always redeploy SIP for Google Voice calling. If you think any of that is likely to happen, you also might want to buy a lottery ticket which affords you about the same chance of seeing any of your dreams come true.

To keep things simple, let’s divide VoIP communications into four categories: inbound calling, outbound calling, messaging, and faxing. We’ll leave video for another day only because it remains a niche product. With the demise of Google Voice, we recommend not putting all of your eggs in one basket (again). Inbound calling is the most critical. That’s your phone number, and it’s how folks get in touch with you. If there are numbers (DIDs) that you don’t want to lose, now is the time to move them away from Google Voice before it’s too late. If Google elects to shut down Google Voice, your ability to port your numbers elsewhere is OVER! So don’t procrastinate on this one. Luckily, Vitelity (one of the primary supporters of Nerd Vittles and the PBX in a Flash projects) has provided an incredible deal to our fan club for many, many years. For $3.95 a month you get a DID with unlimited inbound calls. It’s not free, but it’s not expensive either. And the call quality and service reliability are as good or better than anyone else in the business. You can read all about the offer at the end of this article. Google charges $3 to port your number out of Google Voice to a new provider. The step-by-step tutorial is available in the PIAF Forum. Do it while you still can!

For outbound calling (terminations), the thought process is different. Unlike traditional analog telephony, there is no reason not to have multiple providers especially if you’re using Asterisk, PBX in a Flash, or Incredible PBX as your communications server. If one outbound path fails, your server can automatically send the calls out through another call path. So continue to cling to your Google Voice dream for outbound calling if you’re a Believer. But do a little advance planning while there’s no crisis. There are numerous termination providers and generally you get what you’re willing to pay for. If cheap is your primary objective and call quality is secondary, then Anveo Direct and VoIP.ms can’t be beat. Both allow you to spoof your CallerID to match a DID that you own so they work well with a service such as Vitelity that is being used to handle your inbound calls. We’ve written about both of them, and we use both of them with excellent results. There are many, many others. Visit the PIAF Forum for lots of additional recommendations.

SMS messaging is an evolving technology in the VoIP marketplace. Expect to see some terrific new services before the summer is over. If you’re in a hurry, the easiest current solution to implement is through Anveo Direct. Our recent article will walk you through the setup process to send and receive SMS messages with Asterisk.

Faxing remains a crap shoot using VoIP technology. If you want commercial quality, then choose one of Vitelity’s dedicated fax circuits. If you want analog faxing that usually works, then Anveo Direct and VoIP.ms are about as good as you can do. All versions of Incredible PBX for PBX in a Flash include a free faxing solution using the HylaFax/ AvantFax platform. A similar solution is provided on the Raspberry Pi platform. As we said, it’s not perfect but it usually works.

  1. Larry Page reportedly commented as follows: “I’ve personally been quite sad at the industry’s behavior around all these things. If you take something as simple as IM, we’ve had an open offer to interoperate forever. Just this week Microsoft took advantage of that by interoperating with us but not doing the reverse. Which is really sad and not the way to make progress. You can’t have people milking off of just one company for their own benefit…” []
