If you didn’t already know, we’ve always liked free. No strings, no gotchas, no demoware, and no legal shenanigans. That’s why our introduction of Issabel 4 last summer was such a breath of fresh air. This new release includes the October ISO for Issabel featuring Asterisk® 13.22.0. In addition, it includes our next generation Incredible PBX platform with a preconfigured Travelin’ Man 3 firewall, additional text-to-speech engines (FLITE, GoogleTTS, PicoTTS, and IBM TTS), voice recognition with IBM’s state-of-the-art STT engine, turnkey trunks and extensions, Google Voice GVSIP support for free calling in the U.S. and Canada, SMS messaging, telephone reminders, turnkey fax support, an AsteriDex phone book with both voice and speed dialing, Wolfram Alpha, sample ODBC apps, and a boatload of dialplan code and AGI scripts to help anyone wanting to learn how to develop custom applications with Asterisk®. This is one fantastic platform!

Installing Issabel 4 with Asterisk 13.22.0

Let’s start with the basics and get all of the Incredible PBX components loaded. Begin by downloading the October 2, 2018 Issabel ISO from SourceForge. On the platform of your choice, install Issabel 4 specifying your Keyboard and Installation Destination with Asterisk 13 as your Software Selection. Add the Sangoma WANPIPE component if desired. Set your Root password and have a cup of coffee. After a reboot, you’ll be prompted to set your MySQL/MariaDB root password (must be passw0rd with a zero) and the admin password to login to the Issabel GUI. Be sure to use the new October 2018 Issabel ISO for the base Issabel install. It includes support for Asterisk 13.22.0. We will update things from there as part of the new Incredible PBX install.

Installing Issabel 4 with VirtualBox

For those using VirtualBox, we’ve upload a new Issabel 4 .ova image to SourceForge which will save you some time in getting Issabel up and running. Once you’ve downloaded and installed the image in VirtualBox, you can log in as root using the default password: password. Then you can set your admin password for the Issabel GUI by running /root/admin-pw-change.

Installing Incredible PBX 13 for Issabel 4

As with all Incredible PBX builds, running the Incredible PBX installer will erase ALL of your existing Issabel configuration so start with a fresh install of Issabel.

Begin the Incredible PBX install by logging into your Issabel server as root from a desktop PC using SSH or Putty and execute the following commands:

cd /root
wget http://incrediblepbx.com/IncrediblePBX13-Issabel4.sh
chmod +x IncrediblePBX13-Issabel4.sh

The Travelin’ Man 3 firewall is installed and configured as part of the install. It whitelists certain IP addresses and blocks everyone else from even seeing your server on the Internet. For this reason, it is critically important that you perform the Incredible PBX install using SSH or Putty from a PC that you will use to manage your Issabel server. Otherwise, you risk locking yourself out of your own server. Whitelisted IP addresses include the Issabel server itself, the public and private IP addresses of your desktop PC, all non-routable, private LAN addresses, and the Nerd Vittles collection of recommended SIP hosting providers. You can add as many additional providers or users to the whitelist using the simple tools provided as part of the install and further documented below.

As part of the install process, you’ll be prompted during both passes to create a password for MySQL/MariaDB and an admin password for the Issabel web GUI. The MySQL password MUST be passw0rd (with a zero), or you will get a permanent mess. The admin password can be anything you like. Passwords can be updated by running /root/admin-pw-change. Many of the Incredible PBX apps depend upon this MySQL password so don’t change it. Your MySQL databases remain secure and can only be accessed on localhost or after a successful root login to your server from a whitelisted IP address.

Taking Issabel to the Cloud

The latest Issabel release is only available as an ISO thus far. This complicates Cloud installations since very few providers allow you to upload your own ISO. One such provider that we’ve had good luck with is Vultr. They allow you to upload up to two of your own ISOs. And, for a limited time, your first two months are free (up to $100) using this link.

After you’ve created an account on Vultr, the next step is to upload the latest Issabel ISO. After logging into your Vultr account, choose ISO from the main menu. Then click Add ISO. For the location of the Issabel ISO, use this link. When the upload completes, you’re ready to create your new cloud instance.

For the Server Location, choose one of the cities with $3.50/month availability. For the Server Platform, choose your uploaded Issabel ISO from Upload ISO -> My ISOs. For Server Size, choose the $3.50/month option. An additional 50¢ a month buys you automatic daily, weekly, or monthly backups to a separate, fault tolerant storage system in the same data center. HINT!

(1) Once you’ve built and started your new virtual machine, click on Server Details for your new server. Then click the Console icon, move to the Install (top) option in the Issabel install menu and follow the steps in the previous section to install Issabel. Create a very secure root password when prompted.

(2) When the first phase of the install finishes, your server will reboot. IMPORTANT: During the reboot procedure, you must remove the ISO by choosing Settings -> Custom ISO -> Remove ISO. Once you have removed it, switch back to the Console and click the Ctrl-Alt-Delete button in the upper right corner. Then close and reopen the Console window.

(3) After the reboot, you will be prompted for your default root password for MySQL (must be passw0rd with a zero) and your admin password (your choice) for the Issabel GUI.

(4) When the install finishes, your server will reboot once again.

(5) You now MUST log into your server as root using SSH/Putty from a PC that you plan to use to manage your Issabel server in the cloud, NOT from the Console window. This is important as the Incredible PBX install will automatically whitelist the IP address of this machine. If you perform the Incredible PBX install using the Console, your firewall will lock you out of access until you add a local IP address manually using /root/add-ip.

(6) With the $3.50 size VULTR virtual machine, you must create a swapfile before beginning the Incredible PBX install. Here are the commands:

dd if=/dev/zero of=/swapfile bs=1024 count=1024k
chown root:root /swapfile
chmod 0600 /swapfile
mkswap /swapfile
swapon /swapfile
echo "/swapfile swap swap defaults 0 0">>/etc/fstab
sysctl vm.swappiness=10
echo vm.swappiness=10>>/etc/sysctl.conf
free -h
cat /proc/sys/vm/swappiness

(7) Begin the Incredible PBX install by logging into your Issabel cloud server as root from a desktop PC using SSH or Putty and execute the following commands:

cd /root
wget http://incrediblepbx.com/IncrediblePBX13-Issabel4.sh
chmod +x IncrediblePBX13-Issabel4.sh

Introducing the (new) Travelin’ Man 3 Firewall

Issabel 4 includes an IPtables firewall component. Do NOT activate it because Incredible PBX includes its own preconfigured IPtables firewall, better known as Travelin’ Man 3. With the Issabel 4 firewall, the administrator is responsible for setting all of the firewall rules. With Travelin’ Man 3, all the heavy lifting is done for you. The design is also markedly different. Issabel 4 opens ports which you define, but it gives worldwide access to those ports by any user. Travelin’ Man 3 employs a WhiteList rather than opening ports for everyone. If you’re on the WhiteList, you get access to the limited collection of ports assigned to that IP address. If you’re not on the WhiteList, you cannot even see the Issabel PBX from the Internet. For those without remote telephones or traveling employees, this provides total protection of your server with virtually no further firewall management.

If you have remote users of your PBX or if you wish to deploy softphones on mobile devices and rely upon WiFi facilities at random locations, Travelin’ Man 3 provides several utilities to assist. If the remote users have static IP addresses, then those IP addresses can be added to the WhiteList by running /root/add-ip. Better yet, a NeoRouter VPN is provided that lets remote users access Issabel using NeoRouter private LAN addresses that already are WhiteListed as part of the installation process. These require little to no configuration with static or dynamic IP addresses even when switching between WiFi networks. For those with dynamic IP addresses and no VPN, FQDNs can be assigned using a service such as dyn.com and a dynamic DNS client can be loaded on the smartphone to keep the current IP address synchronized with the FQDN. On the Incredible PBX side, these FQDNs can be added using /root/add-fqdn, and the IP addresses will be updated automatically every 10 minutes. The final option to provide remote users the 3-digit PortKnocker codes from knock.FAQ and let them automatically whitelist their own IP addresses by running the PortKnocker client from any smartphone or Linux server. When the Issabel server detects a successful knock sequence, the source IP of the knock sequence is whitelisted until the next reload of the firewall. If an administrator prefers to allow permanent additions to the WhiteList that survive a reboot or restart of the firewall, the administrator need only run the following command one time: iptables-knock activate. WhiteListed entries can be removed using the /root/del-acct utility. Further details on the new Travelin’ Man 3 design are available here.

We have modified the security methodology to access the AsteriDex and Reminders pages in the web GUI. We have added another layer of security by requiring Apache htaccess credentials before you can access these pages on your Issabel server. What this means is you will be prompted for Apache admin credentials when you attempt to access these pages. As the last step of the Incredible PBX installation procedure, you will be asked to specify your admin password again. This becomes your Apache admin password, and we recommend keeping it the same as your Issabel password so you don’t get confused. In this way, the username admin and the admin password will be used BOTH for Apache authentication AND Issabel GUI authentication. Should you ever need to change your Issabel admin password, run /root/admin-pw-change. You will need to execute the following command to change the Apache admin password: htpasswd -c /etc/pbx/wwwpasswd admin.

Setting Up a Softphone with Issabel 4

If you’re a Mac user, you’re lucky (and smart). Download and install Telephone from the Mac App Store. Start up the application and choose Telephone:Preference:Accounts. Click on the + icon to add a new account. To set up your softphone, you need 3 pieces of information: the IP address of your server (Domain), and your Username and Password. You can decipher your server’s IP address by running pbxstatus. If you wish to use one of the preconfigured extensions (501 and 502), you’ll find the randomized passwords in /root/passwords.FAQ. Now copy or cut-and-paste your Username and Password into the Accounts dialog of the Telephone app. Click Done when you’re finished, and your new softphone will come to life and should show Available. Dial the IVR (D-E-M-O) to try things out. With Telephone, you can use over two dozen soft phones simultaneously.

For everyone else, we recommend the YateClient softphone which is free. Download it from here. Run YateClient once you’ve installed it and enter the credentials for the Issabel extension. You’ll need the IP address of your server plus your extension number and password associated with either the 501 or 502 extension.

Incredible PBX Wholesale Providers Access

Nerd Vittles has negotiated a special offer that gives you instant access to 300+ wholesale carriers around the globe. In lieu of paying the $650 annual fee for the service, a 13% wholesale surcharge is assessed to cover operational costs of TelecomsXchange. In addition, TelecomsXchange has generously offered to contribute a portion of the surcharge to support the Incredible PBX open source project. See this Nerd Vittles tutorial for installation instructions and signup details.

Configuring Google Voice Trunks with Issabel

In July, Google discontinued support for their XMPP interface to Google Voice replacing it with a new GVSIP protocol which is not directly supported in Issabel. So you have two options. First, you can set up an Incredible PBX 13-13 server and interconnect to it for GVSIP trunking support. Simply bring up an Incredible PBX 13-13 server in the Cloud, add the GVSIP components to it from here, and then interconnect the cloud server to your Issabel server to add Google Voice functionality. The cost is about $1 a month.

A second alternative is to sign up for the "free" platform at PBXes.com with a one-time fee of $15. It natively supports GVSIP trunks. You then can interconnect a traditional SIP trunk from your Issabel server to your PBXes platform to activate GVSIP for your users. Last week’s Nerd Vittles tutorial will walk you through the simple procedure to set up your GVSIP trunk at PBXes. Once it’s configured, set up the Issabel side as documented below, and you’ll be ready to enjoy free calling in the U.S. and Canada.

1. Login to the Issabel Dashboard using your favorite web browser.

2. Navigate to PBX -> PBX Configuration -> Trunks and choose the preconfigured pbxes trunk from the list. Uncheck the Disable Trunk field to begin.

3. In the PEER DETAILS section, edit the entries using your newly created PBXes extension and password:


NOTE: Make certain that your Inbound Destination on the PBXes.com side matches the extension number you’ve designated in the three user settings and the registration string.

4. Edit the Register String so that it looks like the following using your actual username-extnumber, extension-password, and DID-number. Then click Submit.


5. Navigate to Basic -> Outbound Routes. Review the Default route. For Dial Patterns, it should look like the following. Verify that the pbxes trunk from the Trunk Sequence pulldown menu. Click Submit to save your entry if you’ve made changes.

6. Navigate to Inbound Call Control -> Inbound Routes. Review the AnyDID route. In the Destination pulldown menu, choose where you would like incoming calls routed, e.g. an extension, ring group, IVR, etc. Then click Submit to save your updated settings.

You now should be able to dial the Google Voice number configured in PBXes and have it ring the Destination you specified in Step #6 above. By registering a softphone or SIP phone to an extension on your Issabel PBX, you should be able to dial a 10-digit or 11-digit number and have the call routed out through your GVSIP trunk registered at pbxes.com.

Adding Speech Recognition Support to Incredible PBX

To support many of our applications, Incredible PBX has included Google’s speech recognition service. These applications include 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!

If you like Siri, you’ll love Wolfram Alpha. To use Wolfram Alpha by phone, you first must obtain a free Wolfram Alpha APP-ID. Then issue the following command replacing APP-ID with your actual ID. Don’t change the yourID portion of the command:

sed -i "s|yourID|APP-ID|" /var/lib/asterisk/agi-bin/4747

Now you’re ready to try out the speech recognition apps. Dial 411 and say "American Airlines" to be connected to American.

To access Wolfram Alpha by phone, dial 4747 and enter your query, e.g. "What planes are overhead now?" Read the Nerd Vittles tutorial for additional examples and tips.

Implementing IBM TTS and Voice Recognition

NOV. 1 UPDATE: IBM has moved the goal posts effective December 1, 2018:

While Google Voice recognition originally was free, it has been a hit and miss platform for the last couple years. If you’re really serious about text-to-speech (TTS) and voice recognition (STT) quality, then you owe it to yourself to make the switch to the IBM platform. For most deployments, the IBM platform will be completely free. Our recent tutorial will walk you through the process of getting your IBM credentials and setting up the TTS and STT functions with IBM Watson. Be advised that you will have two sets of credentials, one for TTS applications and another for STT applications. Once you have your credentials, here are the steps to reconfigure Issabel to use the IBM TTS and voice recognition services. Begin by logging into your server as root and switching to the /var/lib/asterisk/agi-bin directory. Then install the IBM components:

cd /var/lib/asterisk/agi-bin
wget http://incrediblepbx.com/ibm-issabel.tar.gz
tar zxvf ibm-issabel.tar.gz
rm -f ibm-issabel.tar.gz
mv custom/* /var/lib/asterisk/sounds/custom

Implementing IBM STT with Incredible PBX’s Voice Dialer. With this application, a user dials 411 and speaks the name of a person or company to call. The app searches for a match in the AsteriDex directory and places the call. To get started, edit getnumber.sh and insert your IBM STT credentials in the API_USERNAME and API_PASSWORD fields. Then save the file. Replace the Call by Name context by running the following script: ./install-ibm411.sh. Place a test call by dialing 411 and saying "American Airlines."

Implementing IBM STT with Incredible PBX’s SMS Dictator. With this application, a user dials 767, enters the 10-digit number for the recipient of an SMS text message, and then speaks the message to be sent. To get started, edit smsgen.sh and insert your IBM STT and Google Voice credentials using your plain-text Google password. Then save the file. Replace the SMS Dictator context by running the following script: ./install-sms767-dialplan.sh. Place a test call to 767, and the app will send your text message to the recipient’s phone number using the gvoice application. If you experience failed calls, try executing the Unlock Captcha procedure using your Google Voice credentials. Then try again.

Implementing IBM STT with Incredible PBX’s Wolfram Alpha. With this Siri-like app, a user dials 4747 and speaks a query to be sent to Wolfram Alpha for processing. The results then are played back to the caller. To begin, edit wolfram.sh and insert your IBM STT credentials as well as your Wolfram Alpha APPID. Then save the file. Replace the Wolfram Alpha dialplan code by running the following script: ./install-wolfram4747-dialplan.sh. Place a test call by dialing 4747. When prompted for your query, say "What planes are flying overhead now?"

Implementing IBM TTS with Incredible PBX’s News and Weather Apps. With these apps, a user dials 951 for the latest News Headlines from Yahoo or 947 to retrieve the latest weather report by ZIP code. To begin, edit ibmtts.php and insert your IBM TTS credentials in the IBM_username and IBM_password fields. Then save the file. Replace the news and weather by zip code contexts by running the following script: ./install-ibmtts-dialplan.sh.

Generating IBM Voice Prompts to Use with Issabel. We’ve included a script that will let you generate IBM voice prompts that are suitable for use with Issabel and Incredible PBX. To begin, edit ibmprompt.php and insert your IBM TTS credentials in the IBM_username and IBM_password fields. Then save the file. Next, we need to add MP3 support to the SOX application before we can create voice prompts reliably with IBM’s Bluemix TTS service. Here’s how:

yum -y remove sox
yum -y install libmad libmad-devel libid3tag libid3tag-devel lame lame-devel flac-devel
cd /usr/src
wget https://sourceforge.net/projects/sox/files/sox/14.4.2/sox-14.4.2.tar.gz
tar zxvf sox-14.4.2.tar.gz
rm -f sox-14.4.2.tar.gz
cd sox*
make -s
make install
ln -s /usr/local/bin/sox /usr/bin/sox

Generate voice prompts using the following syntax: ./ibmprompt.php "Hello world."

Configuring the Issabel Fax Server

Incredible PBX for Issabel includes turnkey fax support with Issabel. Once you have added a trunk that supports VoIP faxing (HINT: Google Voice trunks work great!), fax configuration with Issabel only takes a minute. Start by logging into the Issabel web interface as admin. First, navigate to PBX:PBX Configuration:Extensions:Fax and obtain your password for extension 329. Next, navigate to Fax:Virtual Fax:New Virtual Fax. Fill in the form as shown below using your actual email address and phone number for receiving faxes as well as your actual extension 329 secret. Then click SAVE. Assuming you typed your secret correctly, you will see a status notification showing virtual fax machine "Running and idle on ttyIAX1."

Assuming you already have set up a Google Voice trunk as outlined above, the next step is to modify the Inbound Route for this trunk to support fax detection. In that way, incoming fax calls will automatically be redirected to extension 329 and the received faxes will be emailed to you in PDF format. Set the email address in Fax:Fax Master. In addition, the faxes can be downloaded and managed from Fax:Virtual Fax:Fax Viewer. Modify your Inbound Route to match the #3 settings shown below. Then save/reload your changes.

To receive the incoming faxes by email, navigate to Fax:Fax Master and enter your email address. Then click SAVE.

The final step is to designate the IP addresses of those authorized to send faxes using Issabel. Navigate to Fax:Fax Clients and specify the public and private IP addresses (one per line) authorized to send faxes. Then click SAVE. Hylafax clients can be used remotely, or you can use the web utility included with Issabel: Fax:Virtual Fax:Send Fax.

The best way to test things out is to send yourself a test fax. FaxZERO lets you send 5 free faxes of up to 3 pages every day. Give it a whirl.

To send a fax out from your server from the Linux CLI using either a text document or PDF file, the syntax looks like the following:

sendfax -n -d 8005551212 smsmsg.txt

Backup and Restore with Issabel

Issabel ships with the most full-featured Backup and Restore options of any of the Asterisk distributions. Ask us how we know. Yes, we managed to wipe out the entire Dashboard menu system on one of our early builds. Restoring from an image took only a couple minutes. To get started, navigate to System -> Backup/Restore. You can create backups locally and then drag and drop them onto a remote FTP server if desired. There is enormous flexibility in choosing what to backup or restore. And there’s even an option to automatically generate periodic backups. You’ll find your backups in /var/www/backup should you ever need to copy them to a new server. Now would be a good time to create your first backup. 🙂

Sampling Other Incredible PBX Applications

As installed, Incredible PBX includes dozens of additional applications for Asterisk. Here’s how to sample some of them using a softphone connected to your Issabel PBX. A good place to start is Allison’s Demo IVR (dial D-E-M-O) using any phone connected to your PBX:

Nerd Vittles Demo IVR Options
1 – 411 -Call by Name (say "American Airlines")
2 – 2663 – MeetMe Conference
3 – 4747 – Wolfram Alpha
4 – 53669 – Lenny (The Telemarketer’s Worst Nightmare)
5 – 951 – Today’s News Headlines
6 – 947 – Weather Forecast (enter a 5-digit ZIP code)
7 – 86329 – Today in History
8 – 701 – Speak to a Real Person

For ODBC demos, dial 222 and enter 12345 for the employee number for a sample database application. Or dial 223 for a sample ODBC dialer using AsteriDex. Enter 263 (first three letters of American Airlines) to place the call. Sample dialplan code is stored in /etc/asterisk/odbc.conf. Dial L-E-N-N-Y (53669) to call or forward telemarketer calls to Lenny. Dial T-I-M-E (8463) for Time of Day. Dial *88HHMM to set an Alarm for HH:MM where HH is the hour of the day in military time. Dial C-O-N-F (2663) for MeetMe conference. Conference credentials are in /root/passwords.FAQ. Voice Dialer (411) works with any database entry in AsteriDex. Access AsteriDex with a browser at https://Issabel-IP-Address/asteridex4. Telephone Reminders can be scheduled by phone (123) or via the web: https://Issabel-IP-Address/reminders. Sample code for the FLITE, GoogleTTS, and PicoTTS engines is in 951 (Yahoo News) context of /etc/asterisk/extensions_custom.conf. All of your FreePBX "old favorites" including blacklists, call transfers and forwarding, dictation, recordings and more are still available as well: PBX:PBX Config:Feature Codes.

Support Issues. With any application as sophisticated as this one, you’re bound to have questions. Blog comments are a difficult place to address support issues although we welcome general comments about our articles and software. If you have particular support issues, we encourage you to get actively involved in the PBX in a Flash Forum. It’s the best Asterisk tech support site in the business, and it’s all free! Please have a look and post your support questions there. Unlike some forums, the PIAF Forum is extremely friendly and is supported by literally hundreds of Asterisk gurus and thousands of users just like you. You won’t have to wait long for an answer to your question.

2018 TREAT: If you could use one or more free DIDs in the U.S. with unlimited inbound calls and unlimited simultaneous channels, then today’s your lucky day. TelecomsXChange and Bluebird Communications have a few hundred thousand DIDs to give away so you better hurry. You have your choice of DID locations including New York, New Jersey, California, Texas, and Iowa. The DIDs support Voice, Fax, Video, and even Text Messaging (by request). The only requirement at your end is a dedicated IP address for your VoIP server. Once you receive your welcome email with your number, be sure to whitelist the provider’s IP address in your firewall. For Incredible PBX servers, use add-ip to whitelist the UDP SIP port, 5060, using the IP address provided in your welcoming email.

Here’s the link to order your DIDs.

Your DID Trunk Setup in your favorite GUI should look like this:

Trunk Name: IPC
Peer Details:
host={IP address provided in welcome email}

Your Inbound Route should specify the 11-digit DID beginning with a 1. Enjoy!
