This week’s project is not for mere mortals. It’s for techies that also happen to be
cheapskates frugal. You may recall the Pogoplug from yesteryear. Well, the Pogoplug 4 still is around and can be yours for under $20 with free 2-day shipping if you’re an Amazon Prime member. But the clock is ticking on these bad boys. Once they’re gone, they’re gone.1
UPDATE: There’s more good news. Now the cost with the Pogoplug Backup & Sharing model is just $10.95! For our purposes, the main difference is one less USB port, but it still has one which is all you need for wireless networking.
So we took the dare and decided to see whether the Pogoplug 4 could actually run Asterisk 11® and FreePBX® 2.11 and Incredible PBX™. And guess what? It may not be pretty, but it works. If you happen to have a Google Voice number and a kid away at school or a grandma in a distant city with an Internet connection or if you have a vacation home or rental property that needs phone service (but not often), then this $20 project may be for you. Configure the device, add a cheap SIP phone, and presto! You’ve got free calling in the U.S. and Canada with your very own phone number for as long as you have Internet service and Google chooses to keep paying your phone bill. 😉
Don’t take our word for it. Call our Pogoplug for a quick IVR demo compliments of Allison:
- Call by Name (just say “American Airlines” to try it out)
- Conference Call (enter 1234# to join the conference)
- Wolfram Alpha (try this: “What planes are overhead?”)
- Lenny (the Telemarketers’ Worst Nightmare)
- Yahoo News Headlines
- Weather Forecasts (say a city and state or country)
- Today in History
- Ring the House Phones (sends you back to Lenny)
Our tip of the hat this week goes to Qui Hong without whom none of this would have been possible. His tutorial on transforming the Pogoplug 4 into a Debian server is a true masterpiece. And his blog is where we begin our adventure once you have the correct Pogoplug 4 in hand: POGO-V4-A3-01. Our link has the correct one, but double-check the Model Number just to be sure.
Converting the Pogoplug 4 into a Debian Platform
Once you have your Pogoplug, you’ll need to scurry over to Qui Hong’s blog and carefully work through his tutorial to convert your Pogoplug into a Debian server. As we’ve said many times before, if you can follow a cookie recipe and end up with edible cookies, then you can do this. Just be very careful of typos. One bad keystroke can turn your Pogoplug into a burnt cookie. Then it becomes a $40 project. 🙂
Installing Incredible PBX 11.12.0 on the Pogoplug 4
Once your Pogoplug has been Debianized, there are five simple steps to get Incredible PBX up and running on your Pogoplug 4:
- Purchase a storage device
- Download Incredible PBX image
- Untar the image on your desktop
- Burn the image to an SD card
- Insert the SD card in the Pogoplug and boot
Choosing a Storage Platform. The first step is to purchase a suitable SD card. We recommend at least a 16GB Class 10 card from Transcend, SanDisk, or Kingston. All of them are about $10 on Amazon and many include free 2-day shipping for Prime customers.
Downloading Incredible PBX for Pogoplug. From your favorite desktop computer, download the latest build of Incredible PBX from SourceForge. Depending upon your network connection and the SourceForge mirror, it can take awhile. It’s a whopping 1.5GB image!
Untarring Incredible PBX for Pogoplug. Depending upon your desktop platform, untarring incrediblepbx.4.pogoplug.D7.latest.tar.gz is as simple as double-clicking on it in the Downloads folder (on a Mac). On the Windows platform, here are 3 utilities that will do the job. On a Linux desktop, open a Terminal window and…
tar zxvf incrediblepbx.4.pogoplug.D7.latest.tar.gz
Burning the Incredible PBX image to SD card. Once you’ve untarred the file, you’ll find two scripts that make burning the image to an SD card simple if you’re on a Mac or Linux desktop. On a Windows machine, it’s a little more complicated. Most SD cards come preformatted with a DOS partition so your Windows machine should recognize the SD card when it’s inserted. If not, format the card using a utility such as SD Card Formatter. Next, you’ll need Win32 Disk Imager to burn pogoplug.img to your card. Once the image has been transferred, gracefully unmount the card from your desktop.
Booting Incredible PBX on the Pogoplug. Insert the SD card (electronics side down) into your Pogoplug 4. Then apply power to the device after connecting an Ethernet cable to a network with Internet connectivity that can also hand out DHCP addresses. Visit your router to decipher the IP address assigned to the Pogoplug and reserve the IP address so that it doesn’t suddenly change down the road. Log into Incredible PBX as root with pogoplug as your password. Your SSH credentials, Asterisk DUNDI secrets, logs, and network connection options will be initialized. When prompted, press Enter to reboot your server. With some SD cards, you may find yourself waiting an eternity for the promised reboot. After seeing the “rebooting” message, count to ten. If your server still hasn’t rebooted, remove and reapply power. This quirk goes away after the first reboot.
After the reboot, log in again as root with password: pogoplug. Your firewall setup will be initialized to lock down your whitelist to your server’s public and private IP addresses AND the IP address of the machine from which you’re logging in. All of your FreePBX passwords will be randomized as well. The whole process only takes a few seconds.
When the second pass configuration is complete, you will be greeted by a welcoming message. STOP and read it. It has loads of important information about your server’s configuration and your next steps. Press ENTER to review status:
The Next 10 Steps. Before you do anything else, complete the following steps. It only takes a minute to secure and properly configure your server:
- Change your root password: passwd
- Change your FreePBX admin password: /root/admin-pw-change
- Set your correct time zone: /root/timezone-setup
- Expand partition to match SD card size: /root/resize-partition
- Add any desired IP addresses to WhiteList: /root/add-ip
- Decipher the randomized password for extension 701. It’s in the data field:
mysql -uroot -ppassw0rd -e "select * from asterisk.sip where id=701 and keyword='secret'"
- Decipher the randomized voicemail password for extension 701. It’s the first entry:
cat /etc/asterisk/voicemail.conf | grep 701 | cut -f 3 -d " "
- Enable Windows Networking, if desired: /root/samba-enable.sh
- Configure PPTP Network, if desired: cat /root/pptp-faq
- Check status to be sure everything is working: status
A Few Important Tips. Every operating system and service provider has their quirks. Ask Bill Gates! Debian and especially Comcast are no different. Fortunately, with Debian, it’s a very short list.
1. Use the following commands (only!) to shutdown and restart your server: halt and reboot. These commands are reworked in Incredible PBX to gracefully shutdown important services so that files don’t get damaged. Please use them!
2. If you ever want to move your server to a different network, complete these steps before you leave your existing network. First, using add-ip or add-fqdn, add the new WhiteList addresses for your new location using Option 0 (all privileges). Otherwise, you won’t be able to access your server once you move. Then issue the commands below. This will trigger a new Phase I update (outlined above) on the default network (eth0) using DHCP the next time you boot your Pogoplug.
touch /etc/update_hostconfig halt
3. You really do need email connectivity to get the most out of Incredible PBX. It’s the way you receive important notifications from FreePBX, and it’s also how voicemail messages are delivered. From the Linux CLI, test your server to be sure you can send emails reliably:
echo "test" | mail -s testmessage firstname.lastname@example.org
After checking your spam folder, if you really didn’t get the email, it may be that your service provider is blocking downstream SMTP traffic. You can use your provider’s SMTP server as a smarthost to send out mail with Exim4. Just run the following program to reconfigure the Exim mail server: dpkg-reconfigure exim4-config. Choose the SmartHost option and enter your provider’s SMTP address, e.g. smtp.comcast.net or smtp.knology.net. Exim will restart.
4. If you’d like to activate ODBC support for Asterisk including our ODBC sample applications including Speed Dial, here are the steps. Log into your server as root and issue the following commands:
cd /root wget http://incrediblepbx.com/odbc-pogoplug.tar.gz tar zxvf odbc-pogoplug.tar.gz rm odbc-pogoplug.tar.gz ./mysql-sample ./mysql-odbc ./odbc-gen.sh
Now you can try things out by dialing 222 from a phone connected to your server. When prompted for the employee number, enter 12345. Or dial 223 and, when prompted for the AsteriDex Dial Code, enter 263 (the first 3 letters of the American Airlines entry).
5. Want a list of your completed calls without using FreePBX? It’s easy:
mysql -uroot -ppassw0rd -e "SELECT SUBSTRING(calldate,6,11) AS calldate,clid,src,dst,duration from asteriskcdrdb.cdr WHERE disposition='ANSWERED' ORDER BY calldate DESC"
6. There may be situations in which it is desirable to use wireless networking instead of a wired connection with your Pogoplug. For under $10, you now can add WiFi. Here’s our post on the PIAF Forum to show you how.
Managing FreePBX with Incredible Backup and Restore
Unlike other releases of Incredible PBX, the backup and restore tools can be helpful on the Pogoplug platform. Even though Asterisk runs smoothly, calls sound great, and performance is pretty amazing, the FreePBX GUI is usable but a bit sluggish on the Pogoplug platform. If the performance bothers you, there’s a workaround. Create an Incredible Backup image of your Pogoplug, restore that image on a more normal Ubuntu 14 platform with ample RAM, and then make your FreePBX changes there using the FreePBX GUI. When you’re finished, make a backup of the changes, and then restore that backup to your Pogoplug. It sounds more complicated than it actually is. In essence, you’ll be transforming FreePBX into an Asterisk code generator. In fact, once a backup is restored, you can shut down your web server, and almost everything will still work. We were able to perform the entire procedure including updating all of the FreePBX modules and adding a Google Voice trunk in about 15 minutes using a snapshot of an Incredible PBX for Ubuntu 14 droplet we previously had created. Here are the actual steps to perform the first time:
1. Take an image snapshot of your server with Incredible Backup: /root/incrediblebackup
HINT: No need to do it initially. One is included: /backup/DU-2014.09.07.19.46-A11.12.0-F2.11-I11.12.0.tar.gz
2. Create a 512MB Droplet on Digital Ocean using Ubuntu 14 and Incredible PBX for Ubuntu. Follow the Nerd Vittles tutorial which also has a signup link to assist our projects. Coupon code: ALLSSD10 gets you a $10 credit this month. Once you’re up and running, you may want to take a snapshot so that you can quickly recreate droplets while also avoiding hourly charges for the one you’ve previously built (whether running or not!). Digital Ocean 512MB droplets cost less than a penny an hour so this is not a big ticket item. When you finish with the droplet, just destroy it (once you’ve made a snapshot!). Then the money meter stops. First time build takes about 30 minutes.
3. After creating /backup folder on DO droplet, copy your backup image from step #1 to this folder.
4. Restore the image: /root/incrediblerestore /backup/DU-somefilename.tar.gz
5. Open FreePBX on DO with a browser and log in as admin with your admin password.
6. Make all the changes desired using the tutorial below. Reload FreePBX (red bar) when prompted before exiting!
7. Make a DO backup of your new setup: /root/incrediblebackup
8. Copy the DO backup file to /backup on your Pogoplug.
9. Restore the DO backup: /root/incrediblerestore /backup/DU-somefilename.tar.gz
10. Log out and back into your Pogoplug as root.
Getting Started with VoIP and FreePBX
To access FreePBX, just point to the IP address of the server. The main control panel looks like this:
As configured, the default user account for FreePBX administration is admin. The password is whatever you set in the initial setup above. If you ever forget it, you can reset it easily: /root/admin-pw-change.
For those new to Asterisk and FreePBX, here’s a brief primer on what needs to happen before you can make and receive calls. If you have an existing Google Voice account, lucky you. This gets you a phone number for your PBX so people can call you. And it provides a vehicle to place free calls to plain old telephones in the U.S. and Canada so long as Google continues to provide the free service.
If you don’t have a Google Voice account or a shiny new smartphone, then you will need to purchase a SIP trunk from one of the numerous vendors around the world. Our favorite (because they provide terrific service at a modest price AND provide financial support to the Nerd Vittles, PBX in a Flash, and Incredible PBX projects) is Vitelity. Their special rates and a link for a discount are included at the end of today’s article.
Unlike POTS phone service from Ma Bell, the SIP World is a little different. First, you don’t need to put all your eggs in one basket. A trunk that gets you a phone number for incoming calls need not be with the same vendor that provides a trunk to place outbound calls. In fact, you may want multiple trunks for outbound calls just to have some redundancy. A list of our favorites in the U.S. and Canada is available on the PIAF Forum. Of course, there also are providers that offer all-you-can-eat calling plans. Two of our favorites are Vestalink and Future-Nine.
You’ll also need a softphone or SIP phone to actually place and receive calls. YATE makes a free softphone for PCs, Macs, and Linux machines so download your favorite and install it on your desktop.
Phones connect to extensions in FreePBX to work with Incredible PBX. Extensions talk to trunks (like Google Voice) to make and receive calls. FreePBX uses outbound routes to direct outgoing calls from extensions to trunks, and FreePBX uses inbound routes to route incoming calls from trunks to extensions to make your phones ring. In a nutshell, that’s how a PBX works.
There are lots of bells and whistles that you can explore down the road including voicemail, conferencing, IVRs, autoattendants, paging, intercoms, CallerID lookups, announcements, DISA, call parking and pickup, queues, ring groups, and on and on. And then there’s all of the Incredible PBX applications which are covered separately in this Nerd Vittles article. Once you’re comfortable with one server, you or your company will want some more. This Nerd Vittles article will walk you through interconnecting them into a seamless mesh network so that you can call from one office to another transparently. Yes, those articles were written for the Raspberry Pi. But the beauty of Incredible PBX is that it runs (almost) identically on every server platform.
Here’s our 7-Step Checklist to Getting Started with FreePBX:
1. Setting Up Google Voice. If you want free calling in the U.S. and Canada, then you’ll need an existing Google Voice account that includes the Google Chat feature. You’ll need one dedicated to Incredible PBX, or it won’t work. Log out after setting up the new Google Voice account! Also note that Google Voice may cease to function at any time after May 15, 2014. You can read all about it here.
- Log into existing Google Voice account
- Enable Google Chat as Phone Destination
- Configure Google Voice Calls Settings:
- Call 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
- Place test call in and out using GMail Call Phone
- Log out of your Google Voice account
If this fails, then Google may have blocked your IP address. Here’s how to unblock it.
2. Activating a Google Voice Trunk. To create a Trunk in FreePBX to handle calls to and from Google Voice, you’ll need three pieces of information from the Google Voice account you set up above: the 10-digit Google Voice phone number, your Google Voice account name, and your Google Voice password. Choose Connectivity -> Google Voice (Motif) from the FreePBX GUI. The following form will appear:
Fill in the blanks with your information and check only the top 2 boxes. If your Google Voice account name ends in @gmail.com, leave that out. Otherwise, include the full email address. Then click Submit Changes and Apply Config.
To activate a Google Voice trunk, you must restart Asterisk on the Pogoplug platform: amportal restart.
3. Setting a Destination for Incoming Calls. Now that you’ve created your Google Voice Trunk, we need to tell FreePBX how to process inbound calls when someone dials your Google Voice number. There are any number of choices. You could simply ring an extension. Or you could ring multiple extensions by first creating a Ring Group which is just a list of extension numbers. Or you could direct incoming calls to an Interactive Voice Response (IVR) system. By default, Incredible PBX is configured to route all incoming calls to extension 701. You can change the setting whenever you like by choosing Connectivity -> Inbound Routes -> Default. In the Set Destination section of the form, change the target destination from the pull-down lists.
Always click Submit and then click Apply Config to save new settings in FreePBX. This is especially important on the Pogoplug platform because you cannot actually do it once you restore the backup image to the Pogoplug.
4. Activating Additional Trunks with FreePBX. As we mentioned, there are lots of SIP providers to choose from. Once you have signed up for service, configuring the trunk is easy. Here is a quick Cheat Sheet courtesy of Kristian Hare, who translated our original setups into a spreadsheet. Just click on the image below to open it in a new window. Then click on the redisplayed image to enlarge it. The left and right cursor keys will move you around in the image. Click on the image again to shrink it.
5. Changing Extension Passwords. From the main FreePBX GUI, choose Applications -> Extensions. Then click on 701 in the Extension List on the right side of your display. You’ll see a form that looks like this:
For now, we only need to make a few changes. First, you need a very secure password for both the extension itself and your voicemail account for this extension. The extension secret needs to be a combination of letters and numbers. The Voicemail Password needs to be all numbers, preferably six or more. Replace the existing password entries with your own (very secure) entries. You also need to lock down this extension so that it is only accessible from devices on your private LAN. You do that with the deny and permit entries which currently are filled with zeroes. Leave the deny entry the way it is which tells Incredible PBX to block everybody except those allowed in the permit entry below. For the permit, we need the first three octets of your private LAN address, e.g. if your LAN is 192.168.0.something then the permit entry will be 192.168.0.0/255.255.255.0.
Finally, you need to plug in your actual email address in the Voicemail section so that voicemails can be delivered to you when someone leaves a message. You can also include a pager email address if you want a text message alert with incoming voicemails. If you want the voicemails to automatically be deleted from the server after they are emailed to you (a good idea considering the disk storage limitations of your microSD card), change the Delete Voicemail option from No to Yes. That’s it. Now save your settings by clicking the Submit button. Then reload the dialplan by clicking on the red prompt when it appears.
In case you’re curious, unless you’ve chosen to automatically delete voicemails after emailing them, you can retrieve your voicemails by dialing *98701 from any extension on your phone system. You’ll be prompted to enter the voicemail password you set up. In addition to managing your voicemails, you’ll also be given the opportunity to either return the call to the number of the person that called or to transfer the voicemail to another extension’s voicemail box. And you can always leave a voicemail for someone by dialing their extension number preceded by an asterisk, e.g. *701 would let someone leave you a voicemail without actually calling you.
6. Eliminating Audio and DTMF Problems. You can avoid one-way audio on calls and touchtones that don’t work with these simple settings in FreePBX: Settings -> Asterisk SIP Settings. Just plug in your public IP address and your private IP subnet. Then set ULAW as the only Audio Codec.
7. Configuring CallerID Superfecta. In order to match names with phone numbers, Incredible PBX includes a FreePBX application named CallerID Superfecta. Out of the box, Incredible PBX will work fine if you remember to activate CallerID Superfecta whenever you create a new Inbound Route. The CNAM entries also will be displayed in your CDR reports. For those not in the United States, you may prefer to use a lookup source for your numbers other than the ones preconfigured in CallerID Superfecta. You will find all of the available modules on the POSSA GitHub site. Just download the ones desired into /var/www/html/admin/superfecta/sources and then activate the desired sources in Admin -> CID Superfecta -> Default. You can test your results and the performance using the Debug facility that’s built into the module.
If you’re using FreePBX on an Ubuntu server in the Cloud, now is the time to drop down to the Linux command prompt, log in as root, and make a backup: /root/incrediblebackup. Copy the backup from /backup to the same folder on your Pogoplug and restore it: /root/incrediblerestore /backup/DU-somefilename.tar.gz. Then restart Asterisk on your Pogoplug: amportal restart. Finally, log out and back into your Pogoplug to assure that FreePBX will function properly on that platform.
Adding Speech Recognition for Incredible PBX Applications
We used to include Google’s Speech-to-Text service in earlier Incredible PBX builds. Unfortunately, Google has changed the rules a bit. Assuming your server still meets the “personal and development” standard, you can obtain an API key from Google and reactivate speech-to-text functionality for many of the Incredible PBX applications including Weather Reports by City (949), AsteriDex Voice Dialing by Name (411), SMS Dictator (767), and Wolfram Alpha for Asterisk (4747). To activate the STT service, just complete the steps in our tutorial. Then sign up for a Wolfram Alpha App ID (tutorial here), and run the following install scripts:
/root/wolfram/wolframalpha-oneclick.sh cp /root/pygooglevoice/bin/gvoice /usr/bin ln -s /usr/bin/gvoice /usr/local/sbin/gvoice cd /root/pygooglevoice python setup.py install /root/smsdictator/sms-dictator.sh
Configuring a YATE Softphone for Pogoplug
As we mentioned, the easiest way to get started with Incredible PBX is to set up a free YATE softphone on your Desktop computer. Versions are available at no cost for Macs, PCs, and Linux machines. Just download the appropriate one and install it from this link. Once installed, it’s a simple matter to plug in your extension 701 credentials and start making calls. Run the application and choose Settings -> Accounts and click the New button. Fill in the blanks using the IP address of Incredible PBX on the Pogoplug, 701 for your account name, and whatever password you’re using for the extension. Click OK.
Once you are registered to extension 701, close the Account window. Then click on YATE’s Telephony Tab and place your first call. It’s that easy!
Introducing Incredible PBX 11.12.0 for the Pogoplug
For those of you that missed last week’s article on the CuBox platform and are new to Asterisk and the world of VoIP telephony, let us take a moment and explain how Incredible PBX fits into the puzzle. For lack of a better term, Incredible PBX is a turnkey aggregation in a bootable image that is based upon a superset of Debian 7 packages plus Asterisk, the FreePBX GUI, and a sizable collection of applications for the Asterisk platform. You download a tarball, decompress it, write the image file to an SD card, insert the card into your Pogoplug 4, and presto! You’ve got a turnkey PBX. Add credentials for a trunk or two to make and receive calls, connect some phones, and your SOHO office or home will come alive with a versatile PBX platform that used to cost organizations hundreds of thousands of dollars. What’s included in Incredible PBX? Glad you asked. Here’s a 3-minute video showcasing a few of our favorite Incredible PBX text-to-speech applications:
The Incredible PBX 11 Inventory. Here’s the current feature set on the Pogoplug platform. In addition to its superset of hundreds of Debian 7 packages, Asterisk 11, and FreePBX 2.11 with the Lighttpd web server, Exim 4 mail server, MySQL, PHP, phpMyAdmin, and the IPtables Linux firewall, check out these additions:

A Few Words About Security. Thanks to its Zero Internet Footprint™ design, Incredible PBX is different. It remains the most secure Asterisk-based PBX around. What this means is Incredible PBX has been engineered to sit anywhere, either behind a NAT-based, hardware firewall or directly on the Internet. No device other than those on your private LAN, a few of the major (trusted) SIP providers around the world, and those that you authorize on your WhiteList can even see your server. Additional IP addresses can be added to the WhiteList by the administrator registering new IP addresses using add-ip or add-fqdn from the Linux CLI. Read about this $100,000 VoIP phone bill, and you’ll better appreciate why WhiteList-based server security has become absolutely essential. WhiteList Security means only those devices with a registered IP address in your WhiteList can get to your server’s resources. To the NSA and everyone else, your server doesn’t even show up on the radar. Their only way to contact you is a POTS telephone using your published phone number. Our complete tutorial on Travelin’ Man 3 is available here. With Incredible PBX for the Pogoplug 4, it’s installed and preconfigured. Enjoy!
Don’t forget to List Yourself in Directory Assistance so everyone can find you by dialing 411. And add your new number to the Do Not Call Registry to block telemarketing calls. Or just call 888-382-1222 from your new number.
