The Most Versatile VoIP Provider: FREE PORTING
JUST RELEASED: Visit the Incredible PBX WikiMeet the New Incredible Fax: A $10 Fax Machine for Asterisk
Every year, technology gets better and cheaper. And, believe it or not, that even includes faxing especially with Asterisk® and Incredible PBX™. Today we take another giant leap forward by introducing fax technology with the $10 Raspberry Pi Zero W. Adding a free Google Voice trunk provides not only free calling in the U.S. and Canada, but now you also get free faxing as well. And the latest release of Incredible PBX lets your RasPi determine whether incoming calls are humans or faxes, and it’ll route them accordingly. To send faxes, you can use the bundled AvantFax GUI client which lets you send PDF documents as faxes with a couple button clicks.
Overview. Once you’ve downloaded the Incredible PBX for RasPi image and made yourself a microSD card for your RasPi, the setup goes like this. First, we’ll configure a WiFi connection to support your server. Then we’ll install a Google Voice trunk. Next, we’ll use the included Incredible Fax installer to put the HylaFax and AvantFax components in place and to set up an email address for delivery of incoming faxes in PDF format. And finally we’ll use the GUI to configure your Google Voice trunk to manage incoming calls from both fax machines and individuals that actually want to talk to you. Faxes will be delivered to your email address, and traditional calls will be routed to a SIP phone or smartphone of your choice. In under 30 minutes, you’ll have a plug-and-play computer that’s about the size of a couple sticks of chewing gum.
Raspberry Pi Zero W Shopping List
Before you can install Incredible PBX, you’ll need a compatible Raspberry Pi Zero W platform. Unless you already have some of the components, the easiest way to begin is to purchase a bundle that includes all the components you’ll need. Here’s your best bet. It’s $35 and includes everything except a USB keyboard and an HDMI monitor and cable. Click on the image for ordering info:
Incredible PBX Installation Tutorial
Here’s everything you need to know about installation and setup. Just follow the links.
- Download and unzip Incredible PBX image from SourceForge (with GV OAuth support!)
- Transfer Incredible PBX image to microSD card
- Boot Raspberry Pi Zero W from new microSD card
- Login to RasPi console as pi:raspberry to initialize your server and configure WiFi
- Reboot after writing down your server IP address
- Login via SSH as root:password to secure your passwords & configure firewall
- Download latest Incredible Fax installer: http://nerd.bz/2nSeHKs
- Install Incredible Fax: /root/incrediblefax13_raspi3.sh (Credentials: admin:password)
Once everything is set up and working, you can remove the keyboard and monitor and put the Raspberry Pi Zero W on a shelf and run it with nothing more than a power adapter. Each time you reboot Incredible PBX, you’ll get an email with the IP address of your server. The recommended setup is to reserve the IP address assigned by your DHCP server in your router’s configuration. Then you have the equivalent of a static IP address while preserving the flexibility to move your RasPi to another network if the need ever presents itself.
Incredible PBX Initialization Steps
With a USB keyboard and HDMI monitor attached to your RasPi, power up the device. Login as pi with the password: raspberry. Incredible PBX first will whir through a few initialization steps. As part of the Raspbian OS, the Raspberry Pi Foundation includes a handy utility called raspi-config. This gets run automatically as part of the initial setup procedure in Step #4. At a minimum, you should configure the following options:
- Expand Filesystem (to use your entire microSD card)
- Wait for Network at Boot (choose Slow to Enable)
- International Options (configure all four options)
- Advanced Options – HostName (name your server)
- Finish (Save your settings but Delay reboot)
Incredible PBX WiFi Setup
The Raspberry Pi Zero W has WiFi-only networking. To get Internet connectivity, you’ll need to configure your server in Step #4 so that it can find your WiFi Access Point. Edit /etc/wpa_supplicant/wpa_supplicant.conf and insert the SSID and password (psk) for your WiFi network. Then save the file. Finally, stop and restart the wlan0 interface on your RasPi device, count to 15, and check the status of your server to decipher the new IP address for your WiFi connection. If no WiFi address, rinse and repeat.
ifdown wlan0 ifup wlan0 pbxstatus
Incredible PBX Phase 2 Configuration
Once you have your network IP address in hand, reboot your RasPi: reboot. Then use SSH or Putty to login to your RasPi from your desktop computer. The credentials are root:password. Complete the setup process by answering the prompts and be sure to set up a very secure root password and GUI admin password for your server.
Configuring a Gmail SmartHost for SendMail
Because of spammers, most Internet service providers now block mail from downstream mail servers. Your RasPi qualifies. There’s an easy way to determine if email service from your server is blocked. Just run the following command substituting your email address. Be sure to check your inbox and spam folder to determine whether you received the email.
echo "This is a test message." | mail -s testmessage yourname@youremaildomain.com
If you flunked the test, here’s what to do next. Modify SendMail to use an existing Gmail account as a SmartHost for email delivery. This means Gmail will actually send the messages rather than your server. Log into your RasPi as root and issue these commands:
cd /etc/mail hostname -f > genericsdomain touch genericstable makemap -r hash genericstable.db < genericstable mv sendmail.mc sendmail.mc.original wget http://incrediblepbx.com/sendmail.mc.gmail cp sendmail.mc.gmail sendmail.mc mkdir -p auth chmod 700 auth cd auth echo AuthInfo:smtp.gmail.com \\"U:smmsp\\" \\"I:user_id\\" \\"P:password\\" \\"M:PLAIN\\" > client-info echo AuthInfo:smtp.gmail.com:587 \\"U:smmsp\\" \\"I:user_id\\" \\"P:password\\" \\"M:PLAIN\\" >> client-info echo AuthInfo:smtp.gmail.com:465 \\"U:smmsp\\" \\"I:user_id\\" \\"P:password\\" \\"M:PLAIN\\" >> client-info nano -w client-info
When the nano editor opens the client-info file, change the 3 user_id entries to your Gmail account name without @gmail.com and change the 3 password entries to your actual Gmail password. Save the file: Ctrl-X, Y, then ENTER.
Now issue the following commands. In the last step, press ENTER to accept all of the default prompts:
chmod 600 client-info makemap -r hash client-info.db < client-info cd .. make sed -i 's|sendmail-cf|sendmail\/cf' /etc/mail/sendmail.mc sed -i 's|sendmail-cf|sendmail\/cf|' /etc/mail/sendmail.mc sed -i 's|sendmail-cf|sendmail\/cf|' /etc/mail/Makefile sed -i 's|sendmail-cf|sendmail\/cf|' /etc/mail/sendmail.cf sed -i 's|sendmail-cf|sendmail\/cf|' /etc/mail/databases sed -i 's|sendmail-cf|sendmail\/cf|' /etc/mail/sendmail.mc.gmail sed -i 's|sendmail-cf|sendmail\/cf|' /etc/mail/sendmail.cf.errors sendmailconfig
Finally, stop and restart SendMail and then send yourself a test message. Be sure to check your spam folder!
/etc/init.d/sendmail stop /etc/init.d/sendmail start apt-get install mailutils -y echo "test" | mail -s testmessage yourname@yourdomain.com
Check mail success with: tail /var/log/mail.log. If you have trouble getting a successful Gmail registration (especially if you have previously used this Google account from a different IP address), try this Google Voice Reset Procedure. It usually fixes connectivity problems. If it still doesn’t work, enable Less Secure Apps using this Google tool.
The last step is to add the following command to /etc/rc.local to send you an email with your IP address and SSID whenever the RasPi is rebooted. Insert the following commands just above the exit 0 line at the end of the file. Use an email address to which you have access on the road!
echo "IP address for your Raspberry Pi: $(hostname -I) plus wireless network, if any: `iwconfig`" | mail -s "Raspberry Pi IP Address" yourname@yourdomain.com
Installing a Google Voice Trunk for Free Calling
If you want to use Google Voice, you'll need a dedicated Google Voice account to support Incredible PBX. The more obscure the username (with some embedded numbers), the better off you will be. This will keep folks from bombarding you with unsolicited Gtalk chat messages, and who knows what nefarious scheme will be discovered using Google messaging six months from now. So keep this account a secret!
IMPORTANT: Do NOT under any circumstances take Google’s bait to switch from Google Chat to Hangouts, or you may forever lose the ability to use Google Chat with Incredible PBX. Also be sure to enable the Google Chat option as one of your phone destinations in Settings, Voice Setting, Phones. That's the destination we need for The Incredible PBX to work its magic! Otherwise, all inbound and outbound calls will fail. Good News! You're in luck. Google has apparently had a change of heart on discontinuing Google Chat support so it's enabled by default in all new Google Voice accounts. Once you've created a Gmail and Google Voice account, go to Google Voice Settings and click on the Calls tab. Make sure your settings match these:
- Call Screening - OFF
- Call Presentation - OFF
- Caller ID (In) - Display Caller's Number
- Caller ID (Out) - Don't Change Anything
- Do Not Disturb - OFF
- Call Options (Enable Recording) - OFF
- Global Spam Filtering - ON
Click Save Changes once you've adjusted your settings. Under the Voicemail tab, plug in your email address so you get notified of new voicemails. Down the road, receipt of a Google Voice voicemail will be a big hint that something has come unglued on your PBX.
UPDATE: Google has improved things... again. You may not see the options documented above at all. Instead, you may be presented with the new Google Voice interface which does not include the Google Chat option. But fear not. At least for now there's still a way to get there. After you have set up your new phone number, click on (1) Settings -> Phone Numbers and then click (2) Transfer (as shown below). That returned the old UI. Make sure the Google Chat option is selected and disable forwarding calls to default phone number.
One final word of caution is in order regardless of your choice of providers: Do NOT use special characters in any provider passwords, or nothing will work!
Now you're ready to configure your Google Voice account in Incredible PBX. First, you'll need to obtain an OAuth 2 token for your Google Voice account. For a complete Google Voice OAuth tutorial, follow steps 8-10 in this Nerd Vittles tutorial. Once you have your credentials, you can do the rest of the Google Voice setup from within the Incredible PBX GUI. Choose Connectivity -> Google Voice. Once you've entered your credentials, you MUST restart Asterisk from the command line, or Google Voice calls will fail: 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. If it still doesn’t work, enable Less Secure Apps using this Google tool.
Another option is to use an inexpensive SIP Gateway to Google Voice. The Simonics trunk in the Incredible PBX GUI is preconfigured for this purpose. All you'll need is your Google Voice credentials. Get started with this tutorial.
Installing Incredible Fax with HylaFax & AvantFax
Once you complete the initial configuration and get your mail server and Google Voice trunk squared away, it's time to run the Incredible Fax installer: ./incrediblefax13_raspi3.sh. You'll be prompted for an email address to which to deliver incoming faxes. After that, everything is pretty much automatic. A few prompts will appear during the installation process. Just press the ENTER key each time and ignore any errors you might see scrolling across your screen. They're harmless. When the HylaFax and AvantFax installs finish, reboot your server. Faxing won't work until you do!
Next, you need to change the default password for AvantFax which is a web-based interface to send faxes and read incoming faxes. From a browser, log into the IP address of your server. When the Incredible PBX menu appears, click the Users tab to display the Administrator menu. Then click on the AvantFax icon to load AvantFax. When prompted for credentials, enter admin:password for your username and password. You'll be prompted to change your password. Make it secure!
Finally, we need to configure your PBX to properly answer calls from fax machines as well as humans. Return to the Incredible PBX Admin menu and click the Incredible GUI icon. Then click the Server Administration icon. When prompted for your username and password, enter admin and the password you configured when you set up your server above. When the System Status screen displays, choose Connectivity -> Inbound Routes -> Default. Make the bottom section of the template look like this substituting your desired Destination for voice calls if you don't want them sent to the Incredible PBX IVR. Click Submit to save your changes and then reload your dialplan when prompted.
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. When you're ready to send a fax from Incredible PBX, log back into AvantFax, click on the Send Fax icon, and follow your nose.

IBM’s Speech Recognition Engine Comes to Asterisk
Eight years ago, we introduced transcription for Asterisk® voicemail messages. When the messages were delivered by email, you got both a recording and the transcribed text courtesy of Google. As with most things Google, the licensing terms changed regularly and voicemail transcription became more convoluted until it became next to worthless. Today we begin our new exploration of IBM’s Watson Developer Cloud. It offers a rich collection of services at unbelievably low price points. We’re kicking things off by introducing a better Speech-to-Text (STT) solution with IBM’s Bluemix. The STT API performs better than any speech recognition engine in the world. And you won’t have to worry about Google breaking our middleware every month. On the Lite plan, up to 100 minutes per month are free. Or you can opt for the Standard pay-as-you-go plan for 2¢ per minute and let your customers yack all they like. That works out to $1.20 an hour which still is pretty cheap secretarial help. In coming weeks, we will introduce IBM’s Text-to-Speech (TTS) offering and Lisa. Up to a million characters of TTS service monthly are free. Here’s a sample to give you a taste of the voice quality:
[soundcloud url="https://api.soundcloud.com/tracks/312693441″ params="auto_play=false&hide_related=false&show_comments=true&show_user=true&show_reposts=false&visual=true" width="100%" height="350″ iframe="true" /]
NOV. 1 UPDATE: IBM has moved the goal posts effective December 1, 2018:
For new deployments, your API Username will be apikey, and your API Password will be your actual APIkey.
Overview. What we’ve done today is integrate the STT Bluemix API directly into existing Asterisk voicemail systems. We started with Nicolas Bernaerts’ terrific sendmailmp3 script. It works on both the Wazo and FreePBX® platforms. If you have deployed Incredible PBX, then the setup takes a couple of minutes. For everyone else, there’s an additional configuration step using your favorite GUI. To get started, you’ll sign up for a Bluemix account and obtain your credentials. Next, you download today’s script for your platform and insert your credentials. Finally, you set up voicemail on the extensions desired and insert an email address for each voicemail account. On generic FreePBX systems, you’ll need to add the name of our script to manage your voicemail recordings.
What About the Quality? Here’s the bottom line. Speech recognition isn’t all that useful if it fails miserably in recognizing everyday speech. The good news is that IBM Watson’s speech recognition engine is now the best in the business. If you want more details, read the article below which will walk you through IBM’s latest speech recognition breakthrough:

Best of Both Worlds: Marrying Asterisk to 3CX’s Free PBX with a $35 Raspberry Pi
One of the real beauties of Asterisk® has always been its flexibility in talking to other PBXs, both commercial and open source. There are numerous reasons why you might want to try this. First, it makes it easy to migrate to a commercial platform where you can get support for mission critical telephony requirements. Second, you may want a hybrid setup where servers with on-site support personnel can run Asterisk while remote satellite offices can take advantage of a commercial PBX and the support options it offers. Third, you may want to take advantage of specific features that are only available by relying upon multiple PBX solutions. In the case of 3CX, their integrated softphone clients with one-click setup simplicity, conferencing and WebRTC apps, and Call Center offerings are the best in the business while providing unmatched VoIP security. Asterisk on the other hand is light-years ahead of almost everybody in the text-to-speech and voice recognition fields while offering the most powerful VoIP toolkit to build any custom VoIP application imaginable.
Today we thought it would be fun to walk you through the easy way to tie an Incredible PBX server with all its features to a powerful (free) 3CX platform with its virtually flawless softphone clients.1 When we’re finished, you’ll have a free 3CX server in the Cloud at a one-time total cost of $17.50. And you’ll be able to place and receive free U.S./Canada calls from any iPhone, Android phone, or PC using the 3CX client from anywhere in the world with nothing more than a WiFi connection. The Google Voice trunk supporting the calls will reside on Incredible PBX for the Raspberry Pi. When you’re sold on the power of the 3CX platform, you can upgrade to the 3CX 4-simultaneous call commercial offering with unlimited users and trunks at an annual cost of just $149. Maintenance and upgrades are included. Large organizations have relied upon back office servers for custom applications forever. And now you can take advantage of the same flexibility using a tiny $35 Raspberry Pi and our free (as in really free) Incredible PBX software. No Gotchas!
Initial Raspberry Pi Platform Setup
Before we can interconnect 3CX’s Free PBX with a Raspberry Pi, you obviously have to set up both PBX platforms. For the Raspberry Pi, our recent Nerd Vittles tutorial will walk you through the setup process. In lieu of a Raspberry Pi, you can use any legacy FreePBX®-based Asterisk platform including Incredible PBX 13, PIAF3, Elastix®, AsteriskNOW®, or FreePBX Distro®. The setup procedure is exactly the same.
Building a 3CX Server in the Cloud
Building a 3CX server in the Cloud is equally easy. Let’s go through the process once again. If you’re just experimenting, a lifetime Cloud-based server at CloudAtCost for a one-time charge of $17.50 cannot be beat. We would hasten to add that we don’t recommend this platform for production use, but it’s a terrific proof-of-concept option. When you’re actually ready to deploy 3CX for production use, the least costly Cloud solution is the $3.49 per month OVH RAID offering with 2GB of RAM and 10GB storage. The $5 per month offerings from Digital Ocean and Vultr are other alternatives worth a look. Both of these platforms come with free credits ($10 and $20, respectively) to let you try things out.
To get started, sign up for a $17.50 server at Cloud at Cost. They will send you credentials to log into the Cloud at Cost Management Portal. Change your password IMMEDIATELY after logging in. Just go to SETTINGS and follow your nose.
To build your free 3CX PBX, create a virtual machine by clicking on the CLOUDPRO button in the CloudAtCost control panel. Then click Add New Server. Choose 1 CPU, 512MB RAM, and 10GB storage for your server. Choose Debian 8 64bit as the OS Type and click Complete.
While CloudAtCost is building your server platform, obtain a free license key for 3CX.
Once the Debian 8 server appears in your Control Panel, it will look something like what’s shown above, not CentOS obviously. The red arrow points to the i button you’ll need to click to decipher the password for your new virtual machine. You’ll need both the IP address and the password for your new virtual machine in order to log into the server which is now up and running with a barebones Debian 8 operating system. Note the yellow caution flag. That’s telling you that Cloud at Cost will automatically shut down your server in a week to save (them) computing resources. You can change the setting to keep your server running 24/7. Click Modify, Change Run Mode, and select Normal – Leave Powered On. Click Continue and OK to save your new settings.
Finally, you’ll want to change the Host Name for your server to something more descriptive than c7…cloudpro.92… Click the Modify button again and click Rename Server to make the change. Your management portal then will show the new server name as shown above.
Next, log in to your new Debian server as root using SSH or Putty and issue the commands below. Step #1 is to change your root password. What appears as the fourth line below is actually part of the third line and needs to be run as a single command. The last line to install SendMail will actually be run after you elect to use the Web Interface Wizard to configure 3CX. Just run it from the SSH command line before you switch to a browser to complete the 3CX setup.
passwd wget -O- http://downloads.3cx.com/downloads/3cxpbx/public.key | apt-key add - echo "deb http://downloads.3cx.com/downloads/3cxpbx/ /" | tee /etc/apt/sources.list.d/3cxpbx.list apt-get update rm -f /zang-debian.sh apt-get -y install 3cxpbx apt-get -y install sendmail sendmail-bin
When the initial setup finishes, choose the Web Interface Wizard and complete the install using your favorite web browser. Enter your 3CX license key when prompted. Make up a very secure Username and Password to access your 3CX portal. Specify that your IP address is Dynamic when prompted (even though it isn’t). This tells 3CX to generate an FQDN for your server. Accept the default ports for HTTP (5000) and HTTPS (5001) access to your server. We recommend choosing 4-digit extensions numbers which will make it easy to distinguish 3CX extension numbers from 3-digit extension numbers of the RasPi platform. While logged into the 3CX management portal, adjust Settings → Email to Mail Server → 127.0.0.1 and Reply to → noreply@YourActual3CX-FQDN. Leave the other settings blank and click TEST then OK. Now download your favorite 3CX smartphone client, send yourself the Welcome Email for your default extension, and your 3CX initial setup is complete.
Server Interconnection Overview
Now we’re ready to interconnect the two servers. What we’ll be doing is creating Trunks on both the Raspberry Pi and the 3CX server and tying them together. We’ll use this trunk to handle the call traffic between the two PBXs. Then we’ll add incoming and outgoing call routes on both servers to specify how the individual calls should be routed. Because the free version of 3CX limits the administrator to a single trunk, we’ll offload all of the provider trunks to the Raspberry Pi and reserve the one available 3CX trunk as the interconnect path to the Raspberry Pi. For today’s setup, we’ll use 3CX’s free softphone clients as the actual phone devices for end-users. Of course, you could also use your favorite SIP phones, and 3CX provides automatic configuration for dozens of devices. But we want to introduce the 3CX smartphone clients because they provide an incredibly easy way to get users connected without having to worry about punching holes in firewalls.
To place outbound calls on the 3CX side, 3CX provides enormous flexibility in call routing. Because we chose 4-digit local extensions when we set up the 3CX server, it will make it easy to route other calls through the outbound trunk to the Raspberry Pi using nothing more than the length of the dial string. For example, 3-digit calls line up perfectly with extension numbers on the Incredible PBX for RasPi platform. So 3CX users can easily reach extensions connected directly to the Raspberry Pi. And 10-digit 3CX calls will be forwarded to the Raspberry Pi as traditional outbound calls. They will be processed just as if you had dialed a 10-digit call from a Raspberry Pi extension. For example, if you have a registered Google Voice trunk to handle 10-digit calls on the Raspberry Pi, then the same call path would be used for calls originating from 3CX extensions. And, yes, calls to the U.S. and Canada would still be free and would display the CallerID associated with the Raspberry Pi’s Google Voice trunk. You could get more creative and add an additional dialing prefix on the 3CX side to route specific types of calls to a designated outbound trunk on the Raspberry Pi side based upon the dialing prefix, but we’ll leave that as a homework project for you.
For incoming calls on the 3CX side, in addition to 4-digit local extension-to-extension calling, we can define the destination for incoming calls that originate from either a Raspberry Pi extension or from outside calls coming in from one of the Raspberry Pi’s provider trunks. These are managed by assigning one or more DIDs in the 3CX trunk configuration and then creating 3CX Inbound DID Rules that tell 3CX where to route calls to each defined DID. For 3CX softphone clients registered to extensions, it means your cellphone will ring whenever a call is routed to that particular extension. On the Raspberry Pi side, we create Incoming Call Routes for each DID to be routed to 3CX and specify our defined 3CX trunk as the destination for incoming calls from those DIDs. Not all DIDs on the Raspberry Pi have to be routed to the 3CX server obviously. That is merely one of many call destination options available to the administrator on the Raspberry Pi server.
Here’s a typical call path for an outside call that is placed to a Google Voice number registered with your Raspberry Pi. The Asterisk server running on the Raspberry Pi would answer the call placed to the Google Voice Trunk. Asterisk then would check for an Incoming Route on the Raspberry Pi with a DID matching the number of your Google Voice trunk. Finding a match, Asterisk would check for the desired destination of the call and would note that it is listed as the registered 3CX trunk. Asterisk would pass the call through this trunk to the 3CX server including its associated DID and CallerID info. The 3CX server would answer the incoming call and would check for an Incoming Route matching the DID passed from Asterisk. Finding a match, it would pass the call to the Extension specified in the Incoming Route. When 3CX rings the extension, it would also detect that a softphone was registered to that extension and would also ring the 3CX client on the user’s smartphone. The user answers the call on the 3CX client of their smartphone and begins a conversation. The free version of the 3CX server supports 8 simultaneous calls so you are unlikely to ever run out of call paths for calls in the home and small office environment.
Firewall Setup for Server Interconnection
Because the 3CX server is sitting in the Cloud, its firewall is configured automatically as part of the setup process. If your Raspberry Pi is sitting behind a NAT-based firewall, then you would need to map port UDP 5060 from the router on your public IP address to the private IP address of your Raspberry Pi. In addition, login to your Raspberry Pi as root using SSH and run /root/add-ip to whitelist the public IP address of your 3CX server in the cloud. Otherwise, the 3CX server cannot establish a connection to your Raspberry Pi.
Raspberry Pi Trunk Configuration
Using a browser, login to the web interface for FreePBX on your Raspberry Pi and choose Connectivity → Trunks → Add SIP (chan_sip) Trunk. Name the trunk remote. In the Outgoing Settings, make the entries shown below naming the trunk remote and using a secure secret that will be used to interconnect the two servers. The Register String looks like the following: main:secret@3CX-IP-Address where main is the 3CX server trunk name, secret is your secure secret, and 3CX-IP-Address is the 3CX public IP address.
3CX Trunk Configuration
Using a browser, login to your 3CX server: https://3CX-IP-Address:5001 or http://3CX-IP-Address:5000. From your Dashboard, choose SIP Trunks → Add SIP Trunk. Create a Generic SIP Trunk and then fill in the blanks as shown below. For Registrar/Server/Gateway Hostname or IP, use the public IP address or FQDN of your Raspberry Pi. For Type of Authentication choose Outbound. The authentication credentials should be remote and the secure secret you chose, and the Main Trunk No should match the DID of the Google Voice trunk you set up on your Raspberry Pi. Then pick a default Destination for incoming calls.
3CX Outbound Rules Configuration
Next, we need to tell 3CX which outgoing calls to send out through the Raspberry Pi trunk we just set up. In our example today, we’re going to send all 10-digit calls and 3-digit calls. The 10-digit calls will be routed out the Google Voice trunk on the Raspberry Pi side. And the 3-digit calls will be sent directly to Raspberry Pi extensions. So we’ll need two Outbound Rules.
For the first rule, choose Outbound Rules → Add. For the Rule Name, specify StandardOut. Apply the rule to Calls to Numbers with a length: 10. For Route 1, choose Generic SIP Trunk as the Destination. Click OK to save the new rule.
For the second rule, choose Outbound Rules → Add. For Rule Name, specify StandardInt. Apply the rule to Calls to Numbers with a length: 3. For Route 1, choose Generic SIP Trunk as the Destination. Click OK to save the new rule.
If you already have configured a 3CX smartphone client for one of your 3CX extensions, you now should be able to dial any 3-digit or 10-digit number and have the call processed through your new 3CX→RasPi trunk without any further setup assuming you’ve created a Google Voice trunk on the Raspberry Pi side. That wasn’t too hard, was it?
Routing Incoming Google Voice Calls to 3CX
Depending upon your own requirements, you may want to route incoming Google Voice calls or other trunks directly to an extension and/or softphone on your 3CX server. You obviously could set up multiple trunks of any type on the Raspberry Pi side and have the calls to each trunk routed to a different extension or softphone on the 3CX side. To enable this on the 3CX side, edit your Generic SIP Trunk and click the DIDs tab. Then Add each of the 10-digit DIDs of the Raspberry Pi trunks you wish to redirect. Next, create an Inbound Rule for every DID and tell 3CX where to route the calls.
On the Raspberry Pi side, add each of your Google Voice Trunks. Then create an Inbound Route for each DID and specify the Destination as Trunks → Remote (sip). The 3CX server will take care of routing the various incoming calls to each of the Google Voice trunks to its predefined extension and/or softphone. Enjoy!

Cellphone Hell: 2017 Minefield Navigation Guide
Well, it’s been an interesting week. RingPlus, a Sprint MVNO, has gone belly up after Sprint pulled the plug on them. Lawsuit details are here. Then, not surprisingly, Sprint announced a new "unlimited" talk, text, and data plan: 5 phones for $90 with a free iPhone with trade-in. After first year, Sprint price escalates to $160 for 4 lines or $190 for 5 lines. And then, Verizon surprised everyone with an "unlimited" plan of their own: 4 phones for $180. With both of these plans, you pay through the nose for the first phone, and then the remaining ones are either free or almost free. So you might as well have some more babies and give them each a phone. For our weary followers that have been with RingPlus, you are about to be introduced to the Sprint Gotcha. Unbeknownst to you, when you inserted that RingPlus SIM and turned on your phone, Sprint locked the phone to their network. And guess what? RingPlus can’t unlock it, and Sprint won’t claiming that you’re not "their customer." But, alas, if you’ve bought your phone, you’re still entitled to use it with a provider of your choice. And, if your phone supports other CDMA carriers such as Verizon or GSM carriers such as AT&T and T-Mobile, you’re in luck. There’s a terrific guy with a company called GSM Zambia, and he will unlock your Sprint phone for $10.84 assuming you have a Windows PC with a USB connector and cable to plug in your phone. For those lucky enough to have a Google-branded phone such as a Nexus or Pixel, you have no worries. Google unlocks it automatically when you insert a SIM card from a different provider.
There are more gotchas awaiting those with iPhones. You see Apple actually makes an iPhone that supports all four of the major U.S. carriers: Verizon, Sprint, AT&T, and T-Mobile. The problem is you probably didn’t get handed that phone. Instead, you got one that was locked to the Sprint network or the AT&T/T-Mobile GSM network, and both of them are missing the necessary radios to support other carriers. But there’s good news. If you’re a loyal customer and have AppleCare for your iPhone, chances are pretty good that Apple will work with you to swap out the phone for one that will work with the carrier of your choice. You have to say this for Apple. Nobody else in the cellphone business would even give you the time of day if you made such a request. So, yes, we are a FanBoy and for very good reason. Apple bends over backwards to help out its loyal customers. Just be advised that you probably will need to speak with an Apple Store manager, and he will probably have to call Cupertino to obtain the document explaining how to handle the transaction. In our case, it was several phones under Apple leases which made things even more complex. But Apple solved it, and they were pleasant about it.
AT&T has had a new "unlimited" plan for about a year, but there were several gotchas in addition to their fine print about what unlimited really means. First, you had to also be a DirecTV customer, but they eliminated that requirement today. And, second, tethering was prohibited. While we’ve previously noted that you could work around the tethering problem by purchasing a ZTE Mobley portable device for your car that could be used outside the vehicle with an adapter. But the wrinkle was AT&T wanted another $40+ a month to cover the device on your unlimited plan. While AT&T boasts that the fourth phone on the unlimited plan is free, it turns out the car device doesn’t meet their definition so, if you only need 3 phones, you still have to cough up the $40 for the mobile device.
T-Mobile also had an "unlimited" plan, but it also restricted tethering. However, T-Mobile is not one to leave money on the table, and they quickly removed the tethering limitation once the Verizon plan was announced. So the bottom line on the 4-phone unlimited plans as of today looks like this: Sprint $90 (10GB tethering), T-Mobile $160 (10GB tethering), AT&T $180 (no tethering), and Verizon $180 (10GB tethering). All four carriers describe their plans as "unlimited" while none truly are insofar as 4G data is concerned. The new buzzword is "deprioritization" which means the carrier reserves the right to slow your data speeds once you reach a certain threshold. Also be advised that zero-rating of certain services is likely to become less of an issue with the Trump administration. In T-Mobile’s case, you get unlimited streaming of certain music and video services at reduced bandwidth. With AT&T, you get streaming of DirecTV movies at reduced bandwidth. With Sprint, you get HD video streaming at no extra cost plus a free iPhone7 for the next 18 months when you trade-in certain older phones. Unless you live in a very busy metropolitan area, user reports suggest that deprioritization shouldn’t be a concern. Here’s the Reddit thread with everything you need to know.
Despite our extreme dislike for almost everything about the Sprint organization and the way they do business, if you happen to live in a city with good Sprint coverage, you really can’t beat their 5 phones for $90 "unlimited" deal at least for one year. After that, Sprint is no bargain at all. If you’re using RingPlus, then that probably means you already have endured Sprint so the change will be easy for you. Just be advised that there are plenty of Sprint reps out there that will try to tell you your phones don’t qualify because they were "prepaid" phones and the plan is only available for "postpaid" phones. A better approach is to visit a Sprint store and advise them that you wish to port your existing phones to the new Sprint unlimited plan. That seems to work although YMMV. Remember, it’s still Sprint you’re dealing with. Good luck!
Feb. 27 Update: The Unlimited Data Plan competition continues to escalate. Today, AT&T sweetened its unlimited plan offering by adding 10GB of free tethering to each phone on its plan beginning Thursday. And T-Mobile announced that customers now can register three phones on its unlimited plan for only $100/month. Unlike Sprint, the T-Mobile offering has no one-year discount cutoff for customers taking advantage of the special pricing. All four major carriers in the U.S. now offer 10GB/month of tethering for each phone on an unlimited data plan.

VoIPtopia 2017: Choosing the Best, Free VoIP Platform
[iframe-popup id="6″]
Once a year we like to step back and survey the latest and greatest VoIP developments for the coming year. And 2016 was certainly filled with surprises including the release of free versions of 3CX sporting the PIAF5 and Elastix 5.0 monikers. That, in turn, produced a wave of FUD from our friends at Sangoma® urging users to return to their open source roots. But guess what? Sangoma was pitching their FreePBX Distro®, another closed source product just like 3CX. Sure, the Sangoma distro has open source components… just like 3CX and your car for that matter. But it’s disingenuous to diss other products because they’re closed source platforms when yours is too. So today we want to cut through the sales pitches and compare apples to apples while offering our Elastix friends this New Year’s Day Resolution:
Ignore the Hype! Look Before You Leap and Avoid Jumping from the Kettle into the Fire.
Funny: Sangoma Reinforces Commitment to Open Source by Offering Migration Tool to its Closed Source Distro https://t.co/8QK22cWyi9 #asterisk

NEWS FLASH: For PIAF3 and Incredible PBX users who have registered on the PIAF Forum, you’ll be getting an invitation to upgrade to the 8-simultaneous-call 3CX commercial platform at no cost. In addition to unlimited extensions, this one-year license adds unlimited SIP trunks and gateways, 10-participant conferencing, G.729 support, custom FQDNs, BLF support, Call Parking, Call Queueing, Call Pickup, Call Recordings and Management, Call Reporting, Intercom/Paging, remote 3CX bridging support, as well as an integrated fax server and Office 365 and Microsoft Outlook integration. If you haven’t already joined the PIAF Forum, there’s still time. But you’d better hurry.
Choosing a VoIP platform is partially a subjective decision, but there also are some glaring red flags to consider. We suggest you begin by deciding whether your preferences include any must-have’s. Do your requirements mandate an open source solution? Do you need text-to-speech and voice recognition? Does the platform have to include Asterisk®, or are you open to alternatives? Does the operating system have to be Linux-based and, if so, must it be CentOS, Debian, or Ubuntu? If you’ll be using SIP phones, must the platform include phone provisioning software for your phones, or is the ability to purchase it as an add-on sufficient? Is paid support important in making your platform decision and how much are you prepared to pay? Are automatic or pain-free software updates critical in making your selection? Is migration from an existing platform a factor? Does a preconfigured, secure firewall matter, or are you prepared to do it yourself or take your chances? Before choosing to ignore security, read last month’s RIPS analysis of FreePBX®. Here’s a snippet from the article. Read it carefully. It’s your phone bill.
Since FreePBX is written completely in PHP, we decided to throw it into our code analysis tool RIPS. The results were more than surprising…
The total amount of detected vulnerabilities is very high. Luckily, the majority of the detected vulnerabilities are inside the administration control panel, such that attackers either need to steal a valid account or they have to trick an administrator into visiting a malicious website that triggers one of the critical vulnerabilities. For example, a remote command execution vulnerability could be triggered by a less critical cross-site scripting vulnerability. By chaining both vulnerabilities, the severity is increased drastically and can lead to full server compromise.
In choosing which platforms to include today, we eliminated platforms which we considered too complicated for the average new user to configure. We also eliminated any platform that did not offer at least a free tier of service with a reasonably complete feature set as part of their offering. If we’ve inadvertently missed one of your favorites, please feel free to leave a comment, and we will consider including it as well. Happy Hunting!

If It Walks Like a Duck and Quacks Like a Duck, Guess What?
WOW! When we started our 2016, The Year of (real) VoIP Choice series, little did we know everything that was about to unfold. It’s been an interesting last few months in the VoIP community with the introduction of PIAF5 and Elastix 5.0 and Ombutel and ThirdLane and this week’s XiVO fork to Wazo. But, stay calm. There is a bright light at the end of this tunnel. You now have MORE FREE VoIP PBX CHOICES than ever before. And every one of them is a rock-solid performer. If the word "commercial" sends shivers through your spine, then Ombutel and this week’s new Incredible PBX for Wazo introduction will make this a very bright holiday season for you. If commercial backing with 24/7 support is your cup of tea, ThirdLane’s free offering includes 10 extensions with full product functionality while PIAF5’s free edition includes unlimited extensions with 8 simultaneous calls, a 5-user conferencing module, a SIP trunk of your choice… and No NagWare! 3CX1 also has made a generous offer for those of you that want to start your own business. You can sign up as a reseller, obtain a full NFR product license, and get free training! And, reportedly, a new Asterisk® VoIP Gateway to 3CX is in the works that will let you tie your existing Asterisk-based PBX directly to 3CX giving you the best of both worlds.2 What’s not to like?
We often wonder why more Fortune 500 companies haven’t adopted open source VoIP solutions when their organizations have computer rooms full of Linux servers. If this election season taught us anything, it’s this. You can learn an awful lot about people in just 140 characters. Here’s a snippet of our exchange last week with the Digium® Chief Technology Officer and Sangoma® Vice President which speaks volumes:
This screenshot brought to you from the AsteriskNOW ISO. If it looks proprietary and smells proprietary, guess what? #asterisk pic.twitter.com/YHtaygnvPb
— Ward Mundy (@NerdUno) December 8, 2016
amazing how clueless crazy guy is
— Tony Lewis (@tonyclewis) December 8, 2016
What’s really crazy is these same individuals have no qualms pitching THEIR proprietary software and THEIR proprietary phones while playing dumb. So how do you square the rhetoric with the fact that SwitchVox® AND AsteriskNOW® and the FreePBX Distro® are all closed source ISOs. One has to ask where was the moral outrage when the FreePBX® devs sold out to SchmoozeCom® and then to Sangoma® or when they turned the FreePBX ISO into a closed source product. That, of course, was different because it was money in their pockets, not to mention cushy new full-time jobs singing the praises of "open source." But nobody wants to talk about any of that. In the real estate business, these guys are called NIMBYs, an acronym for "Not In My Back Yard." They’re all for change as long as it doesn’t affect their own neighborhood and pocketbook. To translate it into VoIP-speak, these are the folks that would prefer you stick with THEIR code generator and buy boatloads of THEIR commercial, closed source modules and THEIR proprietary phones. To everyone else, keep off our playground! Make no mistake. It’s all about the money!
Not surprisingly, a virtually identical feature set is provided at no cost on the ThirdLane and 3CX platforms. So be sure to compare apples to apples and ignore the rants. After all, IT’S YOUR CHOICE. Kick the tires of all the products and choose the platform that best meets your needs and those of your organization. I’m reminded of an old legal adage: "When the facts are on your side, pound the facts. When the law is on your side, pound the law. And when neither is on your side, pound the table." Those that want to distract you from considering the merits of other products by launching attacks on their competitors are little more than table pounders. So consider the source especially when some of the loudest and most vocal members of the fan club are on the payroll hiding behind a cloak of anonymity. None are innocent bystanders. It’s all about the money!
So… are there any Asterisk®-based products that really are released under an open source license? Actually, there are several. The Incredible PBX platforms for CentOS, Ubuntu, and Raspbian as well as the Incredible PBX 13 ISO are all open source products that include the latest LTS version of Asterisk. And then there’s Incredible PBX for XiVO and (NOW!) Wazo, two virtually identical GPL3 platforms that feature an Asterisk real time environment with a more sophisticated GUI and full API support. We’ll have more to say about the latest Wazo release featuring Asterisk 14 later this week. Stay tuned!
Why Incredible PBX? Glad you asked. Here’s my short answer from the PIAF Forum:
The inspiration for Incredible PBX was to save people the unbelievably steep learning curve we endured when first starting to use Asterisk over a decade ago. And, frankly, the developers liked it that way because many of them made a living configuring Asterisk for people that didn’t know what they were doing.
What you get with Incredible PBX?
- You get a secure server out of the starting gate unlike any other distro.
- You get all the tools and samples to learn how to do anything with Asterisk.
- You get a working system out of the box that can make and receive FREE calls.
- You get a pure open source GPL platform with No Gotchas and No NagWare.
What you don’t get with Incredible PBX?
A college degree in telecommunications or network administration without actually doing the work. Yes, it’s hard. But, with Incredible PBX, it can also be fun AND safe.

VoIPtopia: Google Services with Incredible PBX and PIAF5
It’s been a while since we provided a fresh look at Google Voice, Google SMS messaging, and Google’s Speech Recognition labyrinth which have been integral components of Incredible PBX for many years. For those living in the United States, here’s a soup-to-nuts tutorial to get all of the services deployed quickly on any Incredible PBX platform including XiVO and Elastix as well as on the new freeware releases of Ombutel and PBX in a Flash 5 powered by 3CX. On most of the platforms, you can deploy Google Voice services directly; however, with PIAF5, Elastix, and Ombutel you’ll need to set up a SIP trunk using the Simonics SIP to Google Voice gateway to take advantage of free calling in the U.S. and Canada with Google Voice.
Implementing Google Voice with Incredible PBX
Before you can obtain Google Voice service to make free calls in the U.S. and Canada, you’ll need several things: (1) a Google account, (2) access to a computer with an IP address in the United States, and (3) a U.S. phone number to verify your residence for Google Voice.
To get started, sign up for a Gmail account here:
Once your Gmail account is created, click Allow and then Allow and Remember when prompted whether to Allow Gmail to run "Google Talk."
In a separate tab of the same browser, go to Google Voice to sign up for an account. Begin by choosing whether to obtain a new phone number for Google Voice or whether you wish to use an existing mobile phone number that you already own. Next, choose a forwarding phone number which will ring when your Google Voice number is called. NOTE: You do not need to keep this activated on your account once it is completely set up. Be advised that Google also plays games with certain phone numbers such as pretending to ring them when, in fact, they haven’t placed a verification call at all. This usually is because of prior abuse of the number with the Google Voice service or because you’ve gotten greedy and signed up for too many free numbers. If a number doesn’t work for verification, you’ll need to choose another number. And it’s usually a good idea to create additional Google Voice accounts from different IP addresses. Once you complete the verification step, you can choose a phone number in an area code of your choice. Same thing holds for picking phone numbers. If you get error messages saying to "try later," what Google is really telling you is you’re a greedy bastard. Set up additional Google Voice numbers from a different computer using a different IP address and chances are the problem will go away. It did for us. 😉
Once you have your new Google Voice number, Google will drop you into the Voice Inbox. Ignore offers to activate, enable, or do anything else with Hangouts. Otherwise, you may kill the ability to use your new Google Voice number with Asterisk®.
Click on the Settings Gear icon in the upper-right corner of the window. In the Phones tab, make certain that (1) Google Chat is enabled and (2) your forwarding phone number is disabled:
In the Calls tab, make it look like this for proper Google Voice operation with Asterisk:
You now have a basic Google Voice setup on the Google side to support Asterisk calling. But the default setup uses plain-text passwords for your Google Voice account, and this is not only a security issue, but it also will cause problems if you move your Google Voice account to a different computer. For that reason, we strongly recommend setting up OAuth 2 authentication for your Google Voice account.
Obtaining an OAuth 2 Token for Google Voice
To deploy Google Voice with OAuth 2 authentication on the Incredible PBX platforms that support direct connections to Google Voice (Incredible PBX 13 and Incredible PBX for XiVO), you will first need to obtain an OAuth 2 Refresh Token from Google. On the remaining platforms that require a SIP account using the Simonics SIP to Google Voice gateway (PIAF5 powered by 3CX, Ombutel, and Elastix), you can skip this section since the Simonics site will obtain the refresh token for you as part of the signup process.
While you’re still logged into your Google Voice account, you need to obtain a refresh_token which is what you’ll use instead of a password when setting up your Google Voice accounts with Incredible PBX 13 and Incredible PBX for XiVO. Here’s how.
1. Be sure you are still logged into your Google Voice account. If not, log back in at https://www.google.com/voice.
2. Go to the Google OAUTH Playground using your browser while still logged into your Google Voice account.
3. Once logged in to Google OAUTH Playground, click on the Gear icon in upper right corner (as shown below).
3a. Check the box: Use your own OAuth credentials
3b. Enter Incredible PBX OAuth Client ID:
466295438629-prpknsovs0b8gjfcrs0sn04s9hgn8j3d.apps.googleusercontent.com
3c. Enter Incredible PBX OAuth Client secret: 4ewzJaCx275clcT4i4Hfxqo2
3d. Click Close
4. Click Step 1: Select and Authorize APIs (as shown below)
4a. In OAUTH Scope field, enter: https://www.googleapis.com/auth/googletalk
4b. Click Authorize APIs (blue) button.
5. Click Step 2: Exchange authorization code for tokens
5a. Click Exchange authorization code for tokens (blue) button
5b. When the tokens have been generated, Step 2 will close.
6. Reopen Step 2 and copy your Refresh_Token. This is the "password" you will need to enter (together with your Gmail account name and 10-digit GV phone number) when you add your GV trunk in Incredible PBX 13 GUI. On the XiVO platform, log into your server as root and run: /root/add-gvtrunk. Store this refresh_token in a safe place. Google doesn’t permanently store it!
7. Authorization tokens NEVER expire! If you ever need to remove your authorization tokens, go here and delete Incredible PBX Google Voice OAUTH entry by clicking on it and choosing DELETE option.
Switch back to your Gmail account and click on the Phone icon at the bottom of the window to place one test call. Once you successfully place a call, you can log out of Google Voice and Gmail.
Yes, this is a convoluted process. Setting up a secure computing environment often is. Just follow the steps and don’t skip any. It’s easy once you get the hang of it. Sleep well.
Configuring Google Voice Trunks with Incredible PBX
The setup procedure differs a bit with Incredible PBX for XiVO and Incredible PBX 13.
With Incredible PBX for XiVO, log into the Linux CLI with your root credentials and run: /root/add-gvtrunk. Enter your Google email address, refresh token, and 10-digit Google Voice number when prompted. Follow the instructions which appear when the script finishes, and you’ll have a functioning Google Voice trunk in less than a minute.
With Incredible PBX 13, log into the Incredible GUI as admin using a web browser. Choose Connectivity -> Google Voice -> Add Account and fill in your Google Username, Refresh Token, and 10-digit Phone Number. Check the Add Trunk and Add Outbound Route check boxes. Then click Submit. Create an Inbound Route to tell Asterisk how to route incoming calls to your 10-digit DID. Finally, log into the Linux CLI as root and restart Asterisk: amportal restart.
Simonics SIP to Google Voice Gateway Setup
There’s a one-time fee of $4.99 to use the Simonics gateway if you take advantage of the Nerd Vittles signup link. All remaining Google services are free. You obviously can use the Simonics gateway with almost any PBX that supports SIP trunks, but it’s particularly well-suited for PBXs that don’t natively support Google Voice with OAuth 2 authentication such as PIAF5, Ombutel, and Elastix. To get started, you’ll need to set up an account at Simonics using your existing Google Voice credentials.
1. Using your favorite browser, log in to the Google Voice account you wish to associate with the Simonics SIP gateway. Be sure that you’ve enabled Google Chat in your Google Voice setup.
2. Using a separate tab of your browser, connect to the Simonics Google Voice Gateway site.
3. Go through the steps to register your Google Voice account with the Simonics Google Voice gateway and obtain your credentials.
4. For those using PIAF5, Ombutel, or Elastix, use another tab of your browser to open the GUI interface and create a new SIP trunk using your new Simonics SIP login credentials. With Incredible PBX 13, here’s the drill. Replace 8005551212 with your actual Google Voice number and YOUR-SIP-PW with your actual Simonics SIP password in BOTH the PEER Details and Registration String. Add your Google Voice number to the end of the Registration String like this: GV18005551212:YOUR-SIP-PW@gvgw.simonics.com/8005551212
5. Regardless of PBX platform, the next step is to create an Inbound Route for your incoming calls using either your Simonics username or the 10-digit number you entered at the end of the Registration String in step #4a. This obviously depends upon your PBX platform.
6. Create an Outbound Route for outgoing calls that should be handled by your Google Voice trunk. The CallerID number will be your Google Voice number. You cannot change it.
7. If you’d prefer to send incoming calls from the Simonics gateway to a designated SIP URI instead of the server that registered with the Simonics gateway, enter the address in the format: pbx@myserver.xyz. For additional details, read our previous article on SIP URIs.
SMS Messaging with Google Voice
On the Incredible PBX 13 and Incredible PBX for XiVO platforms, the python setup to support SMS messaging through Google Voice is already installed. On the PIAF5, Ombutel, and Elastix platforms, you’ll first need to install it. Here’s how.
Log into your server as root using SSH or Putty and issue the following commands to install the Google Voice CLI tools:
cd /root apt-get -y install python-setuptools wget http://incrediblepbx.com/install-gv-cli chmod +x install-gv-cli ./install-gv-cli
Before the SMS messaging tools will work, there are two preliminary steps that you must complete on every platform. This is because SMS messaging with python uses plain-text passwords for Google Voice, and Google imposes new hoops that you must jump through in order to continue to use such passwords. While logged into your Google Voice account with a browser, click on this link to Enable Less Secure Apps. Next, click on this link to Activate the Google Reset Procedure. You now have a couple of minutes to actually connect to your Google Voice account from your new server using plain text passwords. This will WhiteList the IP address of your server. So let’s send an SMS message quickly so that everything gets squared away.
To Send an SMS Message Blast to one or more destinations, (1) create a message in /root/smsmsg.txt, (2) specify the SMS numbers in /root/smslist.txt, (3) insert your Google credentials (using your plaintext Google Voice password) in /root/smsblast, and (4) run /root/smsblast to send the message.
Implementing Google’s Speech Recognition API
Speech Recognition currently works with Incredible PBX 13 and Incredible PBX for XiVO only. But we’ll be collaborating with the 3CX folks to bring it to their platform soon. All of the necessary components to use speech recognition for voice dialing from the AsteriDex phonebook (411) and to take advantage of the Siri-like Wolfram Alpha service (4747) already are in place with Incredible PBX 13. While voice dialing works great with XiVO, Wolfram Alpha is just around the corner on the XiVO platform. Before you can actually use voice recognition, you’ll need a Google API key since Google handles the speech-to-text translation on the Asterisk platform thanks to Lefteris Zafiris’ terrific speech-recog AGI script. Here’s a revised step-by-step tutorial to get your API key from Google and activate it on your PBX.
Place a test call by dialing 4-1-1 and saying "Delta Airlines" when prompted. You should be connected to Delta’s reservation system. Enjoy!

The Stealth AutoAttendant for Incredible PBX and PIAF5
This week we’re dusting off an oldie but goodie, The Stealth AutoAttendant. If you missed our original column 8 years ago, here’s a quick refresher. When a call comes into your PBX, a generic greeting is played: "Thanks for calling. Please hold a moment while we locate someone to take your call." Then the call is transferred to an extension or ring group. Stealth comes into play because this is really an AutoAttendant and, while the greeting is played, a caller can press a preassigned key to transfer the call to some other destination. While it’s obviously not a secure method for providing additional phone features to certain callers, it’s nevertheless helpful in opening up additional PBX functionality without making callers feel like they’re dealing with yet another IVR when they call your home or office. Using the 12-button keypad and clever design, features such as conferencing and DISA can be offered while still providing security through added prompts for passwords or PINs.
https://youtu.be/dB-Tr3WnrKE
In addition to releasing GPL voice prompts from Allison Smith, today we’ll show you how to implement this on three different platforms: Incredible PBX 13 with its FreePBX® GPL modules, Incredible PBX for XiVO®, and PBX in a Flash 5 powered by 3CX®.
Stealth AutoAttendant Voice Prompts
Let’s start by getting you the voice prompts to support the Stealth AutoAttendant. What’s included is a copy of the GPL3 license and versions of the voice prompts in both GSM and WAV format. The prompts are identical except one has a two-second pause at the beginning of the prompt. This is helpful to avoid premature playing of the voice prompt when using trunk providers such as Google Voice that take a couple seconds to set up audio on a call. You can experiment with both and see which best meets your own requirements.
For the techies, it’s probably worth documenting how these prompts were created. We started with GSM versions of both our Generic Greeting prompt and the 2-second silence prompt that can be found on most Asterisk® servers. These were then converted to WAV format: sox 2.gsm -s -b 16 2.wav. Then the WAV files were combined like this:
sox -m 2.wav nv-GenericWelcome.wav nv-GenericWelcome2.wav
Now let’s download the Stealth AutoAttendant prompts to your desktop. The files are available in stealth.zip and stealth.tar.gz format so choose the download that is easiest for you to work with. Once downloaded, unzip or untar the compressed files.
Stealth AutoAttendant with Incredible PBX 13
On the Incredible PBX 13 platform with its FreePBX GPL modules, there are 3 steps to implement the Stealth AutoAttendant. The tricky part in setting up the Stealth AutoAttendant is getting the prompt installed so that it can be used as an Announcement when building an IVR in the GUI. So let’s start there.
1. FreePBX provides a facility for importing existing voice prompts in the GUI. Login as admin to get started. Then go to Admin → System Recordings → Upload and import the generic greeting desired from your desktop. Name the recording and then click Save to add it to your server.
2. Next choose Application → IVR and create a new IVR using the generic greeting as your Announcement. You can follow the IVR Demo template provided with Incredible PBX if you need some hints on how to set up an IVR. Or, better yet, review the Nerd Vittles IVR tutorial.
3. The final step is to point the Inbound Route for one or more of your DIDs to the Stealth AutoAttendant to take incoming calls. Go to Connectivity → Inbound Routes and set the Destination for the DID to the IVR you just created.
Stealth AutoAttendant with Incredible PBX for XiVO
For those using the Incredible PBX for XiVO platform, the voice prompt for the Stealth AutoAttendant already is in place in /usr/local/share/asterisk/sounds. Just copy it to /var/lib/xivo/sounds/playback in order to use it as a voice prompt with your IVRs:
cp -p /usr/local/share/asterisk/sounds/nv-GenericWelcome.wav \\ /var/lib/xivo/sounds/playback/.
Currently, there is no GUI to create IVRs and AutoAttendants with XiVO, but an IVR GUI is in the works so stay tuned. In the meantime, our tutorial and IVR template (ivr-1.conf in /etc/asterisk/extensions_extra.d) will show you how easy it is to create the dialplan code. Just copy it (cp -p) to stealth-aa.conf as a starting point. To use the Stealth AutoAttendant voice prompt, simply change the third line from ivr-Allison and replace it with the new voice prompt: nv-GenericWelcome. It doesn’t get much easier than that.
Finally, using the XiVO GUI, navigate to IPBX → Call Management → Incoming Calls and create a new incoming route for your DID that points to the IVR template you created.
Stealth AutoAttendant with PIAF5 powered by 3CX
On the PIAF5 and 3CX platform, implementing the Stealth AutoAttendant is the easiest of all. It’s all done on a single screen. You get what you pay for. 🙂 Start by logging into the 3CX web portal. When the Dashboard appears, click on Digital Receptionist in the left toolbar. Next click Add. 3CX will automatically assign an extension number for your new IVR, e.g. 800. Assign a new friendly name: Stealth AutoAttendant. Then click the Upload button to upload the WAV prompt from your desktop. Choose the options desired for your Stealth AutoAttendant and designate the DID(s) to use for incoming calls to the Stealth AutoAttendant. In the Destination for no or invalid input, set the Timeout to 2 seconds and choose where to route incoming calls when the caller presses no keys or when the input is invalid. This means the caller has the duration of the greeting plus 2 seconds to press a key and divert the call to another destination. Click OK to save your settings. Told you it’s easy.
