Hard to believe it’s been five years since the introduction of the original Raspberry Pi®. Over ten million RasPi’s have been shipped. The latest and greatest Raspberry Pi 3 features a 1.2GHz 64-bit quad-core ARM Cortex-A53 CPU with ten times the performance of the original Raspberry Pi. And today we’re pleased to introduce the 2017 edition of Incredible PBX™ for Raspbian 8 featuring Asterisk® 13 and Google Voice OAuth 2 support. It installs in under a minute. Of particular interest to the VoIP community will be the RasPi 3’s integrated 802.11n wireless LAN and Bluetooth 4.1 hardware. And, of course, the RasPi 3 retains its compatibility with the Raspberry Pi 1 and 2. Did we mention it’s still just $35? And, yes, Incredible PBX will always be FREE, secure, and pure open source GPL code. No Gotchas!

Raspberry Pi 3 Performance. Gone are the days of worrying about Raspberry Pi performance. Both the user interface and call quality now match what you’d expect to find on a $300-$500 VoIP server. Even with a Raspberry Pi 2, we have detected no performance degradation thanks to the latest Raspbian 8 OS and a virtually flawless Asterisk 13 platform. For best results, we recommend 32GB Class 10 microSD cards which now are plentiful at the $10 price point.1

Raspberry Pi 3 Shopping List. Before you can install Incredible PBX, you’ll need a compatible Raspberry Pi 3 platform. Here’s the short list:

  • $35* Raspberry Pi 3 from MCM or Newark or Amazon
  • $10 Power Adapter (2.5 amps minimum!)
  • $11 32GB microSDHC Class 10 card
  • £12.95 Rainbow Pibow case or $7.42 Official RasPi3 case
  • About That Asterisk. We write about Asterisk® regularly, but the asterisk we’re talking about is the one accompanying the $35* price tag for the Raspberry Pi 3. Yes, that’s the advertised price. And, no, you’re probably not going to pay that. There are the marked up shipping prices, the bundled add-on’s that you don’t need or want, and the must-have accessories like a power adapter. We’re assuming you already own a USB keyboard and an HDMI-compatible monitor. If so, just plan on $100 and consider yourself lucky if you get all the pieces for less. Our order from Pimoroni in the U.K. with a case and 3-day shipping was £59.36 or $82.95 U.S. Ordering just the RasPi3 from MCM is $42.99 including shipping.

    Incredible PBX Feature Set. Where to begin? Let’s start with the Alphabet Stew: IAX, SIP, GVSIP, SMS, Opus, and SRTP functionality. Voice Recognition and Text-to-Speech VoIP application support using FLITE, GoogleTTS, and PicoTTS. Free calling with Google Voice, Simonics SIP gateway, or RingPlus cellular service. And all of your Nerd Vittles favorites: Fax, AsteriDex, Click-to-Dial, News, Weather, Reminders, and Wakeup Calls. Plus hundreds of features that typically are found in commercial PBXs: Conferencing, IVRs and AutoAttendants, Email Delivery of Voicemail, Voicemail Blasting, and more…

    10-Layer Network Security Model. Most phone calls cost money. Unlike many of the other “free” VoIP solutions, our most important criteria for VoIP is rock-solid security. If your free server ends up costing you thousands of dollars in phone bills due to fraud, guess what? It isn’t free at all. Once you plug in that network cable, you’ve painted a bullseye on your checkbook.

    No single network security system can protect you against zero-day vulnerabilities that no one has ever seen. Deploying multiple layers of security is not only smart, it’s essential with today’s Internet topology. It works much like the Bundle of Sticks from Aesop’s Fables. The more sticks there are in your bundle, the more difficult it is to break them apart. If a vulnerability suddenly appears in the Linux kernel, or in Asterisk, or in Apache, or in your favorite web GUI, you can continue to sleep well knowing that other layers of security have your back. No one else in the telecommunications industry has anything close. Ours is all open source GPL code so we would encourage everyone to get on board and do their part to make the Internet a safer place!

    Configuring Trunks with Incredible PBX

    Before you can actually make and receive calls, you’ll need to add one or more VoIP trunks with providers, create extensions for your phones, and add inbound and outbound routes that link your extensions to your trunks. Here’s how a PBX works. Phones connect to extensions. Extensions connect to outbound routes that direct calls to specific trunks, a.k.a. commercial providers that complete your outbound calls to any phone in the world. Coming the other way, incoming calls are directed to your phone number, otherwise known as a DID. DIDs are assigned by providers and you register your trunks using credentials handed out by these providers. Incoming calls are routed to your DIDs which use inbound routes telling the PBX how to direct the calls internally. A call could go to an extension to ring a phone, or it could go to a group of extensions known as a ring group to ring a group of phones. It could also go to a conference that joins multiple people into a single call. Finally, it could be routed to an IVR or AutoAttendant providing a list of options from which callers could choose by pressing various keys on their phone.

    We’ve done most of the prep work for you with Incredible PBX. We’ve set up an Extension to which you can connect a SIP phone or softphone. We’ve set up an Inbound Route that, by default, sends all incoming calls to a Demo IVR. And we’ve built a dozen trunks for some of the best providers in the business. Sign up with the ones you prefer, plug in your credentials, and you’re good to go.

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

    With the preconfigured trunks in Incredible PBX, all you need are your credentials for each provider and the domain name of their server. Log into Incredible PBX GUI Administration as admin using a browser. From the System Status menu, click Connectivity -> Trunks. Click on each provider you have chosen and fill in your credentials including the host entry. Be sure to uncheck the Disable Trunk checkbox! Fill in the appropriate information for the Register String. Save your settings by clicking Submit Changes. Then click the red Apply Config button.

    Configuring a Softphone for Incredible PBX

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

    We recommend YateClient which is free. Download it from here. Run YateClient once you’ve installed it and enter the credentials for the 701 extension on Incredible PBX. You’ll need the IP address of your server plus your extension 701 password. Choose Applications _> Extensions -> 701 and write down your SIP/IAX Password. You can also find it in /root/passwords.FAQ. Fill in the blanks using the IP address of your Server, 701 for your Username, and whatever Password you assigned to the extension when you installed Incredible PBX. Click OK to save your entries.

    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:

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

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

    Configuring Google Voice

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

    IMPORTANT: 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 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’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.

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

    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.

    Speech Recognition with 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!

    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. Do NOT 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 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 access Wolfram Alpha by phone, dial 4747 and enter your query, e.g. “What planes are overhead.” Read the Nerd Vittles tutorial for additional examples and tips.

    Enabling WiFi on the Raspberry Pi

    With the Raspberry Pi 3, wi-fi hardware is included. With the Raspberry Pi 2, you’ll need to add an inexpensive wifi dongle. The next step is connecting to your WiFi router. Simply open /etc/wpa_supplicant/wpa_supplicant.conf with your favorite editor and insert the following code using the actual SSID name and password to access your local, password-protected WiFi router or any open WiFi network:


    Finally, stop and restart the wlan0 interface, count to 15, and check the status of your server to decipher the new IP address for your WiFi connection:

    ifdown wlan0
    ifup wlan0

    If you want to run your Raspberry Pi exclusively off the WiFi connection, simply unplug the network cable from your RasPi and reboot your server.

    Lessons Learned with the Raspberry Pi 3

    As with all new devices, you learn some things as you go along. So we’re providing an update to our original article to offer a couple of additional tips and tricks for those that want to travel with a RasPi…

    Alternative Power Sources. If you’re like us, you have a number of devices around the house or office that all require 5V power adapters of various amperages. The Raspberry Pi has traditionally been one of the most temperamental when it came to power adapters and, with the Raspberry Pi 3, the developers specifically mention a 2.5 amp minimum. If you travel and want to take devices such as the Raspberry Pi with you, the last thing you want to do is approach airport security with a bunch of wires hanging out of your carry-on bag. Well, there’s good news. The Anker device shown in the Amazon ad in the right column of Nerd Vittles can supply power to 6 devices including a Raspberry Pi 3. And we’ve given the RasPi a healthy workout with no adverse effects.

    Deciphering the RasPi IP Address. As we mentioned, we travel a lot so obtaining a DHCP address for your RasPi in WiFi mode is not always the easiest thing to accomplish. If your smartphone supports tethering, that’s the easiest way to get connectivity on the road. A better way is to stick a WiFi HotSpot in your luggage and it, too, can be powered using the Anker device. See our recent article for WiFi HotSpot choices. Regardless of which option you choose, it will require some planning to use your RasPi sans monitor and keyboard. First, you need to preconfigure /etc/wpa_supplicant/wpa_supplicant.conf with the SSID of the device you’ll be using to hand out DHCP addresses. You’ll note from the discussion above that each entry in this file has a priority with higher numbers having higher priority. The way we typically do this is to assign our home network as the highest priority. Below that, we set up credentials for our MiFi Hotspot, then our smartphones, and finally open networks. So it looks like this:

    • Home Network – 6
    • MiFi HotSpot – 5
    • Android phone – 4
    • iPhone (AT&T) – 3
    • Open Network – 1

    Keep in mind that the Incredible PBX firewall probably will block you from accessing the RasPi from a computer on the public network. So you also must connect your computer to the same private WiFi network because private LAN addresses are whitelisted in the firewall by default.

    Once you have connectivity for your RasPi and your laptop, the other wrinkle is figuring out the IP address of the Raspberry Pi. Our recommended approach goes like this. First, configure SendMail on the RasPi to use a Gmail account that you own as an SMTP smarthost to send emails. That should work almost anywhere you go. Second, modify /etc/rc.local to automatically send you an email with the IP address and SSID of your wireless network whenever the RasPi boots. Again, this takes some advance planning because you need to set all of this up and test it before you go on the road.

    Here are the steps to modify SendMail to use an existing Gmail account as a SmartHost. Log into your RasPi as root and issue the following 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 ..
    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

    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(es) for your Raspberry Pi: $(hostname -I) plus wireless network, if any: `iwconfig`" | mail -s "RaspberryPi3 IP Address" yourname@yourdomain.com

    GoogleTTS has been hit-and-miss for many years as Google continues to “improve things.” Lefteris Zafiris has worked his usual magic and updated the scripts for Asterisk once again. These are required to use Incredible PBX features such as Yahoo News. To install the latest GoogleTTS updates, simply log out of your server and log in once again as root. The Incredible PBX Automatic Update Utility will put all of the new pieces in the correct places.

    1. Will this work for the Beaglebone Black?

      [WM: No.]

    2. Can this also be installed on a Raspberry Pi 2? What is it using, Wazo or FreePBX?

      [WM: RasPi2 should be fine, but slow. This image includes FreePBX 12 GPL modules in the modified GUI, not Wazo. There’s a separate image here for XiVO on the RasPi3 platform. Wazo and XiVO are not well-suited for use on a microSD platform because of the realtime implementation of Asterisk.]

    3. I love your site! It is such a goldmine! I am a programmer and I always wanted to try getting my hand dirty with VOIP, especially on the PI. Thank you so much for all those great info, images and the hard work!
      I have a beginner question. I made some research but didn’t find anything satisfying. How do I connect and make call from outside my place? I understand that PortKnock allows only my Public IP and my local network to access the PBX.
      I am using a SIP application called Softphone from Acrobits, and inside my private network, it works great! But from outside, no luck. It only works when I am on my VPN.
      I believe that this is the expected behavior for security, but is there a solution for users on their mobile with no VPN?

      Thank you in advance for pointing me in the right direction!

      [WM: Here’s a tutorial that will walk you through whitelisting remote phones with Incredible PBX. The PIAF Forum also is an excellent resource when you hit a snag. Good luck.]

    4. Hi there. the script that runs on this is missing sudo prefixes throughout the second half and fails miserably. Just thought I’d let you know.

      [WM: If you follow the tutorial, you won’t have the problem. You forgot to login as root in step #6.]

    5. Thanks for the GREAT work – you and your team. I’ve been with you since the AAH days.

      Is it possible to make it support either/both gvoauth and no oauth in the same release. I always have problems getting oauth to work but no oauth seems to work the first time?

      I have a RPi-2 working with no auth and do not want to mess up the GV side of things.

      [WM: Hi, Tom. Thanks for the kind words. We’ve heard your suggestion from a number of folks, and we’re reconsidering although I hasten to add that Google is going to discontinue support for plain-text passwords sooner rather than later so… you might as well learn how to obtain one. A link is provided in the article to show you how. It’s not hard, and it’s much safer.]

    6. I don’t seem to get opus working. It says it is installed, but I can’t figure out how to enable it. Could you please elaborate?

      [WM: Please head over to the PIAF Forum for tech support on Opus. Thanks.]

    7. Is it possible to install this on an existing Pi image? I’d prefer to download scripts (I found reference an older version: incrediblepbx11guiPi.tar.gz ) as opposed to imaging an SD card. I have a few minor apps running I would like to keep in the background.

      [WM: Sorry, but it’s gotten too complicated to provide an upgrade script.]

    8. I love running my home Asterisk pbx on pi but having serious troubles with data corruption, database errors, and so forth which leads me to rebuild it every few months. Any recommendations before i migrate away from pi?

      [WM: Easiest solution is to add a USB Drive to your RasPi and run everything from there. This tutorial will show you how.]

    9. Great stuff on this site! I was just wondering what is the difference between this version of Incredible PBX and Incredible PBX for XiVO?

      [WM: The two products use different GUIs. XiVO takes considerably more horsepower to run because it implements Asterisk Real Time.]

    10. Wondering whether Incredible PBX will work with a $5 Raspberry Pi Zero W? Wonder no more. Setup instructions using WiFi available here.
