The Most Versatile VoIP Provider: FREE PORTING
JUST RELEASED: Visit the Incredible PBX WikiSkype + Asterisk (still) = Beautiful Music + Free Phone Calls
It's been a disappointing week for Asterisk® with Digium®'s announcement1 that Skype® for Asterisk will no longer be available for sale after July 26, 2011. While many suspected that Microsoft might have been behind the development, it turns out according to Skype2 that this had been in the works for several months so that the company could better focus its attention on Skype for SIP. The problem with that argument, of course, is that at least for now you can't make outbound calls to Skype users with Skype for SIP unless the Skype users happen to be paying for a Skype to Go DID. So where do we go from here?
Well, the good news is that Asterisk 1.8.4.1 now appears to qualify as a stable release with fixes to several nasty bugs which caused some Cisco and Polycom phones to no longer connect. And Skype still produces a client for Linux. And Greg Dorfuss still produces SipToSis, an amazing product that lets Asterisk systems communicate with Skype... in both directions.
The problem has been that the most current release of Skype for Linux required GLIBCXX_3.4.9 which is not part of the CentOS 5.x distribution even though it is available in current releases of Fedora. What you never, ever want to do is mix and match components from one Linux distribution in another. They don't call it Dependency Hell without reason. But, as luck would have it, there's always a guru somewhere that's smart enough to get all the pieces working together.
For those using Incredible PBX, today's your lucky day. We've written a little script that takes all the components outlined above and makes them play nice at least on most Atom-based computers. You still need a sound card that's compatible with CentOS 5.6, but once you're past that hurdle, it's smooth sailing to integrate Skype into your existing system. We'll leave it to you to sort out the licensing issues which do not appear to be problematic if your system is solely for personal use. After all, Skype still produces a Linux client for use on Linux systems, and that's what Incredible PBX happens to run on.
If you use the recommended hardware, today's setup procedure takes less than 10 minutes! Once it's complete, inbound and outbound Skype calling is totally transparent on your Incredible PBX. To reach a Skype number, just dial * plus the user's Skype name from any phone with an alphanumeric keypad. To place a Skype Out call (fees apply), dial 8 plus the user's area code and number. When your 500 million friends on Skype contact you using your Skype name, all of your Incredible PBX phones will ring just like any other inbound call. What's the difference in today's solution and Skype for Asterisk? For openers, today's solution is $66 cheaper. It's free! And, if you're an individual, you won't need Skype's commercial Business Control Panel to make calls. Functionally, the results with your Incredible PBX Skype implementation are identical.3
To make the Skype Magic work, you'll need three pieces of software in addition to The Incredible PBX obviously: Sun's 6u12 Java SE Development Kit, Skype's Static Edition for Linux plus an existing Skype account, and Greg Dorfuss' SipToSis product which manages the Skype Gateway to Asterisk.
As far as hardware is concerned, we're assuming you're using our recommended Acer Aspire Revo to host your Incredible PBX although most Atom-based PCs should work just fine. We don't recommend EEE PCs. With other hardware, your mileage may vary because CentOS 5.6 may or may not support your audio card and graphics mode with your video card. Both are required to get Skype working properly under X-Windows. If you have problems with some other type of hardware, take a look at the tips in our previous article on Setting Up a Skype Gateway to Asterisk as well as the comments.
Installing JDK. Using your favorite browser, go to Sun's 6u12 Java SE Development Kit website, choose Linux for the platform, and agree to the license. Click Continue. Download jdk-6u12-linux-i586-rpm.bin and copy it to the /root directory of your Incredible PBX. Next, make the file executable (chmod +x jdk-6u12-linux-i586-rpm.bin). Then run it: ./jdk-6u12-linux-i586-rpm.bin. Scroll down the wordy license agreement AGAIN and type yes. Java 1.6 then will be installed on your system. Check to be sure Java was properly installed with this command: rpm -q jdk.
Installing Skype and SipToSis. Now we're ready to load the remaining components. While still logged into your Incredible PBX as root, download and run the skype-setup script. NOTE: We recommend you make a good backup of your system before you begin!
cd /root
wget http://incrediblepbx.com/skype/skype-setup
chmod +x skype-setup
./skype-setup
Activating Your Skype Gateway. Now we're ready to place your Skype gateway in production. You'll need to perform these steps from the console on your Incredible PBX since we have to run Skype in graphics mode. This may look complicated. It's really not. It's just a bit tedious to figure out the sequence of steps, but we've done that part for you.
WARNING: Be sure that you use a dedicated Skype account on this server! Do not run the same Skype account on any other server or desktop, or it fails!
1. Start up X-Windows: xinit4
2. Start up Skype. While still logged into your server as root, issue the following commands:
skype.sh
Now you need to log in to Skype with your Skype name and password. In this latest version of Skype, we've noticed a quirk. Enter your password before you enter your username, or the system may not accept your username. If the screen appears frozen, press Ctrl-C and try it again. Be sure to set Skype to autologin whenever it is started. Then, in the Skype configuration option, set Skype to always run minimized. Save your settings.
Place a Skype Test Call5 to echo123 to be sure your audio settings are set correctly. Again, with the Aspire Revo, this won't be a problem assuming you have plugged in a microphone and speakers. These can be disconnected after you're sure things are working properly. HINT #2: Intel Atom-based motherboards are a piece o' cake!
Once you've got Skype working and all of the Skype settings configured above, shut down Skype.
3. Restart Skype in Background Mode: skype.sh &
Be sure to write down the PID for Skype in case you need to kill the job if something goes wrong. 🙂 If you forget the PID, you can obtain it with this command: pgrep skype. You can kill Skype with the following command using your actual PID instead of 12345: kill 12345.
4. Start up SipToSis: Press Enter if the command prompt doesn't reappear. Then...
cd /siptosis
./SipToSis_linux
A message from Skype will pop up asking if you want to authorize external use of Skype: yes. Important: Be sure to also select the Checkbox to save this setting for future connections!
5. Testing Skype. Go to a softphone (X-Lite recommended!) connected to an extension on your Incredible PBX and dial *echo123. You should be connected to the Skype Call Testing Service. Try *nerdvittles for the Nerd Vittles Demo.
Assuming you have a little money in your Skype Out account, go to any extension connected to your Asterisk server and dial 8 + your home phone number. This will place the outbound call through SkypeOut at 2¢ a minute.
Reboot your server when you're sure everything is working properly.
GUI Tips. Here are a few navigation tips for managing your Asterisk console on your Incredible PBX:
1. Ctrl-Alt-F2 gets you a new login prompt for your server
2. Ctrl-Alt-F7 gets you back to the SipToSis/Skype session. You can kill SipToSis by holding down Ctrl-C for several seconds. To decipher your SipToSis PID: pgrep -f SipToSis. To kill SipToSis: kill pid# (that you wrote down). To kill Skype: kill pid# (that you wrote down). To restart Skype: skype.sh & and to restart SipToSis, just issue the command again: ./SipToSis_linux
3. Ctrl-Alt-F9 gets you to the Asterisk CLI.
Automating the Skype Gateway Startup. Once everything is working reliably, reboot your server again, log in as root, and issue the command: /root/skype-start. Place a test call again using a softphone on your Incredible PBX. If everything works fine, you now can add the skype-start command to your server's startup script, and you're all set.
echo "/root/skype-start" >> /etc/rc.d/rc.local
Setting Up Speed Dials for Skype Friends. One of the wrinkles with Skype is that Skype uses names for its users rather than numbers. If you don't have a SIP URI-capable softphone, there's still an easy way to place calls to your Skype friends using FreePBX. Just add a Speed Dial number to your FreePBX dialplan. Choose Extension, then select the Custom type, provide an Extension Number which is the Speed Dial number (this could actually spell your friend's name using a TouchTone phone), enter a Display Name for your friend, and add an optional SIP Alias. Then insert the following in the dial field replacing joeschmo with your friend's actual Skype name. Save your entries and reload the dialplan when prompted.
SIP/joeschmo@127.0.0.1:5070
Security Warning. Do NOT expose UDP port 5070 to the Internet by opening a port on your hardware firewall. You do not need UDP 5070 exposed to the Internet to implement today's gateway solution for inbound or outbound Skype calling from your server!
Enjoy!

Changes in PBX in a Flash Distribution. In light of the events outlined in our recent Nerd Vittles article and the issues with Asterisk 1.8.4, the PIAF Dev Team has made some changes in our distribution methodology. As many of you know, PBX in a Flash is the only distribution that compiles Asterisk from source code during the install. This has provided us enormous flexibility to distribute new releases with the latest Asterisk code. Unfortunately, Asterisk 1.8 is still a work in progress to put it charitably. We also feel some responsibility to insulate our users from show-stopping Asterisk releases. Going forward, the plan is to reserve the PIAF-Purple default install for the most stable version of Asterisk 1.8. As of June 1, Asterisk 1.8.4.1 is the new PIAF-Purple default install. Other versions of Asterisk 1.8 (newer and older) will be available through a new configuration utility which now is incorporated into the PIAF 1.7.5.6.2 ISO.
Here's how it works. Begin the install of a new PIAF system in the usual way by booting from your USB flash drive and pressing Enter to load the most current version of CentOS 5.6. When the CentOS install finishes, your system will reboot. Accept the license agreement, and choose the PIAF-Purple option to load the latest stable version of Asterisk 1.8. Or exit to the Linux CLI if you want a different version. Log into CentOS as root. Then issue a command like this: piafdl -p beta_1841 (loads Asterisk 1.8.4.1), piafdl -p 184 (loads Asterisk 1.8.4), piafdl -p 1833 (loads Asterisk 1.8.3.3), or piafdl -p 1832 (loads Asterisk 1.8.3.2). If there should ever be an outage on one of the PBX in a Flash mirrors, you can optionally choose a different mirror for the payload download by adding piafdl -c for the .com site, piafdl -d for the .org site, or piafdl -e for the .net site. Then add the payload switch, e.g. piafdl -c -p beta_1841.
Bottom Line: If you use the piafdl utility to choose a particular version of Asterisk 1.8, you are making a conscious decision to accept the consequences of your particular choice. We would have preferred implementation of a testing methodology at Digium before distribution of new Asterisk releases; however, that doesn't appear to be in the cards. So, as new Asterisk 1.8 releases hit the street, they will be made available through the piafdl utility until such time as our PIAF Pioneers independently establish their reliability.

Some Recent Nerd Vittles Articles of Interest...
- "Skype for Asterisk will not be available for sale or activation after July 26, 2011. Skype for Asterisk was developed by Digium in cooperation with Skype. It includes proprietary software from Skype that allows Asterisk to join the Skype network as a native client. Skype has decided not to renew the agreement that permits us to package this proprietary software. Therefore Skype for Asterisk sales and activations will cease on July 26, 2011. This change should not affect any existing users of Skype for Asterisk. Representatives of Skype have assured us that they will continue to support and maintain the Skype for Asterisk software for a period of two years thereafter, as specified in the agreement with Digium. We expect that users of Skype for Asterisk will be able to continue using their Asterisk systems on the Skype network until at least July 26, 2013. Skype may extend this at their discretion. Skype for Asterisk remains for sale and activation until July 26, 2011. Please complete any purchases and activations before that date. Thank you for your business." [↩]
- Skype is a trademark of Skype, Inc. "Skype made the decision to retire Skype for Asterisk several months ago, as we have prioritized our focus around implementing the IETF SIP standard in our Skype Connect solution. SIP enjoys the broadest support of any of the available signaling alternatives by business communications equipment vendors, including Digium. By supporting SIP in favor of alternatives, we maximize our resources and continue to reinforce our commitment to delivering Skype on key platforms where we can meet the broadest customer demand." [↩]
- Skype and this suggested implementation are intended for individual use. Your use is, of course, governed by the Skype Terms of Service. [↩]
- Starting xinit won't be a problem on the Aspire Revo. But, if xinit won't start on your particular machine, you may need to create /etc/X11/xorg.conf. Here's a generic config file that should work fine for our purposes:
Section "ServerLayout"
Identifier "X.org Configured"
Screen 0 "Screen0" 0 0
EndSectionSection "Device"
Identifier "Card0"
Driver "vesa"
EndSectionSection "Screen"
Identifier "Screen0"
Device "Card0"
SubSection "Display"
Viewport 0 0

Modes "800x600"
EndSubSection
SubSection "Display"
Viewport 0 0
Depth 16
Modes "800x600"
EndSubSection
EndSection[↩]
- If the test call fails with a bad audio message, go into Options, Sound Devices and reconfigure your Audio settings until you can place the test call successfully. Otherwise, none of the rest will work! [↩]
Incredible PBX: Adding Google Calendars with Asterisk 1.8
One of the exciting new features in Asterisk 1.8 is external calendar integration including iCal, caldav, Microsoft Exchange, and ews. Hats off to Terry Wilson at Digium® for his great work on the calendaring API. Unfortunately, there hasn’t been much written about integrating the calendars into FreePBX®-based Asterisk® systems… until now. Because we’re all about free, our focus today will be Google Calendar integration, but we’ll provide you some links to get any of the other calendar types integrated into PBX in a Flash and Incredible PBX if that’s what floats your boat. In addition to being free, Google Calendar is one of the best calendaring apps on the planet. Its beauty lies in the incredible flexibility it provides for group scheduling and the sharing and transparent integration of dozens of calendars (both public and private) not to mention real-time updating with your favorite Android smartphones. Apple does much the same thing with iCal on the Mac and iPhone… for an annual fee.
The rainbow of colors you see in the left column of the screenshot above each represent a different calendar. All of the calendar entries from all of these calendars are integrated into the single calendar display on the right with a simple color scheme to identify where each calendar entry originated. As mentioned, these calendars can not only be from your friends and business associates, they also can be publicly available, read-only calendars for subject matter such as holidays, schedules of your favorite sports teams and rock bands, school calendars, etc. Take a look at iCalWorld to get a quick handle on what’s available. See also this Google resource.
The one bit of advice we would provide in setting up Google Calendar is don’t put all your eggs in one basket. Create separate calendars for different individuals and for different types of events. And don’t mix business with personal. Also keep internal business events separate from those that you might want to share with customers. Down the road, this facilitates sharing just the information of importance to different groups of friends and business associates. Bottom Line: Spend a little time thinking about organization of your calendars. It will pay off handsomely down the road.
Once you integrate Google Calendar into Incredible PBX, you can use it to alert you to upcoming appointments, to schedule and activate conference calls, and even to log the date, time, length, and recipient of all your outbound and/or incoming phone calls.
For today, we’ll get the software installed and functioning. And we’ll help you set up a simple reminder system based upon appointment entries in your Google Calendar. We’ll also give you some good reference materials so that you can experiment a bit on your own. In coming weeks, we’ll build a time slips system to keep track of all your phone calls.
Prerequisites. As mentioned, you’ll need a Gmail account as well as Asterisk 1.8 and PIAF-Purple with Incredible PBX 1.8 to follow along in today’s tutorial. All of the pieces are optional except for Asterisk 1.8 and a fairly current version of FreePBX, but we’ll leave that exercise for the pioneers. The script is licensed as GPL code so knock yourself out.
The Gotchas. Nothing is ever easy, is it? There always are a few surprises to worry about. Here’s the current short list for Asterisk Calendaring. When you schedule a meeting or appointment with Google Calendar, there is an option to set an alert to remind you of the meeting at any time you like on a per appointment basis. So, if you have a meeting 50 miles from home, you could set the alert for 90 minutes in advance while a meeting next door could be set with a 5 minute alert. All of that works fine in Google Calendar. Unfortunately, in Asterisk 1.8.4, there’s a math bug that subtracts the hour differential between your time zone and Greenwich Mean Time (GMT) from these alert times. If you happen to live in the GMT time zone, there’s no bug. However, those living on the East Coast of the U.S. will find their reminder calls arriving four hours too early. If you set an alert for 60 minutes before a scheduled meeting, Asterisk will call you 5 hours in advance. For our West Coast friends, it’s an 8 hour bug. Fortunately, the Asterisk Calendaring config file provides an option to override these alerts with a reminder call at a fixed number of minutes before each appointment. While it lacks the individual appointment flexibility to schedule alerts of different durations, it does work. So, for the time being, we’ll be using that.
Asterisk Calendar alerts also were supposed to be triggered only for events in which your Status has been set to Busy. A typical example would be a medical appointment. Instead, the alerts are generated for all calendar entries. So, if you’ve got 12 children and you’ve set all-day calendar entries to remind you of their birthdays each year, be forewarned that using your default Google Calendar will trigger a friendly reminder call at 11:50 p.m. on the night before each of your kids’ birthdays. Unless you and your spouse are both Night Owls, this might lead to some "WAF issues" if you get our drift. The workaround that we’ll implement today is to create a secondary appointments calendar and reserve it just to schedule meetings and appointments for which you wish to receive reminder calls at 10 minutes before each event. You can change the notification time to any fixed number of minutes desired. As we mentioned, one nice feature of Google Calendar is that entries on secondary calendars will automatically display on your main calendar. Just be sure to schedule the appointments on the correct calendar (we’ll show you how) if you want a reminder call.
Setting Up a Google Appointments Calendar. Before we get Asterisk configured for calendaring, let’s first set up your secondary Google appointments calendar. Log into the Gmail account that you either already use or will begin using for scheduling Calendar entries. Just click on the Calendar tab at the top of the screen and set up your default calendar if it doesn’t already exist. Once it’s set up, there will be a calendar list in the left margin under My Calendars. Just below your existing Calendar(s), there will be a Tasks entry, and below that will be an Add link to add a new calendar. Click on Add and fill in the main pieces of information as shown below. Use appointments for the name of the calendar and make sure you set the correct Time Zone for your hometown. Then save your entries by clicking the Create Calendar button.
Once you have created your new appointments calendar, we need one other piece of information to use it with Asterisk. Under My Calendars in the left margin, click on the down arrow beside appointments and choose Calendar Settings. That will bring up a form that looks like this:
The next to the last section of the form is entitled Calendar Address. You’ll see an entry to the right of the section title called Calender ID with a long alphanumeric string followed by @group.calendar.google.com. Write down the Calendar ID or copy it to clipboard. Don’t include @group.calendar.google.com! You can ignore the statement that the link is inoperative unless you make your calendar public. It actually works just fine with your Google credentials which we’ll configure as part of the Asterisk setup below.
Configuring Asterisk for Google Calendar Integration. PBX in a Flash and Incredible PBX come with most of the components you’ll need to get calendaring to work. However, there are a few missing pieces at the moment. These will require that Asterisk be recompiled, and we’ve built a little script to do all of it for you. Just log into your server as root and issue the following commands:
cd /root
wget http://incrediblepbx.com/setup-cal.sh
chmod +x setup-cal.sh
./setup-cal.sh
After you enter your Google credentials and Calendar ID, the script will temporarily shut down Asterisk, download the missing components for calendaring, recompile Asterisk, and customize the calendar setup with your Google credentials. Then the script will complete the setup and restart Asterisk. The whole process takes about 5 to 10 minutes.
Asterisk Calendar Configuration. Here are the pieces in the default Google Calendar config file that will be replaced with your personal settings:
[GoogleCalendar]
type = caldav
;url = https://www.google.com/calendar/dav/username@gmail.com/events/
url = https://www.google.com/calendar/dav/CalendarID@group.calendar.google.com/events/
user = username@gmail.com
secret = userpassword
refresh = 10
timeframe = 120
;
autoreminder = 10
;
channel = local/8005551212@from-internal
context = from-internal
extension = 225
waittime = 45
If you should ever need to make changes to these settings again, you’ll find the entries with your Google credentials at the end of the calendar.conf config file in /etc/asterisk. Remember to restart Asterisk after making any changes. The commented out URL entry is the one you’d use to access your main Google Calendar instead of the secondary appointments calendar we created above. If the GMT bug is ever fixed, this would be a step forward.
Extension 225 (C-A-L) is the extension that will be called to actually play back the reminder information. You’ll find this block of code at the top of extensions_custom.conf in the [from-internal-custom] context. You can make any adjustments you’d like. We simply set this up to give you a template to follow. As configured, the reminder will read you a summary, the starting time, location, and any description associated with each calendar entry. If you have a Cepstral voice in addition to Flite, just change the Flite entries to Swift. Then restart Asterisk: amportal restart.
Asterisk Calendar Test Drive. Asterisk keeps track of your scheduled events by checking your Google Calendar every 10 minutes. We recommend configuring reminders for calls 10 minutes before any scheduled event in the appointments calendar. What this means is you probably should never schedule an event expecting to get a reminder call if the event is less than about a half hour in the future. If you use a setting for the autoreminder time other than 10 minutes, this will obviously be different for you.
So let’s schedule an appointment for an hour from the current time. Click on the Calendar tab in Gmail. And then click on the down arrow beside the appointments calendar in the left column. Choose Create Event on this Calendar. You’ll get a form that looks like this. Click Save to store your new Calendar entry. Then go have a beer and wait for your call.
Where To Go From Here. We’ve just scratched the surface of what you can do with Asterisk 1.8 using Google Calendars. We recommend you now review the chapter in the new Asterisk Definitive Guide book that covers calendaring in some detail. It will give you a good handle on what’s possible. For a more technical discussion, take a look at this contribution from one of the PIAF Forum regulars. Amazing stuff! There’s also a good article in VoIP Today that’s worth a careful read. Be aware that, if you recompile Asterisk to add support for Microsoft Exchange, you probably will break the Google Calendar connection that we’ve outlined today. At least, we never have been able to get the two to coexist. If you have better luck, please post your results. The reason for the problem is that the Exchange connector depends upon neon-0.29 which is not yet part of CentOS 5.x. We’ll keep you posted on our progress. Enjoy!

Incredible Fax: Free Faxing Returns to Incredible PBX 1.8
It’s been a rocky road getting an open source (free) faxing alternative to work reliably with Asterisk® 1.8. To further complicate things, CentOS 5.6 was finally released which brought us a few more Asterisk 1.8 headaches and updates finally leading up to an all-new and nearly perfect PBX in a Flash 1.7.5.6 thanks in large part to Tom King. The new release also forced some under-the-covers modifications in Incredible PBX. Now you’re caught up on last week’s news. But what have we done for you lately?
Well, one alternative was to shift gears to the commercial Fax for Asterisk from Digium® which is supported in FreePBX 2.8 and 2.9 and includes one free license. But we’re open source fans and, of course, nothing beats free. Thanks to the efforts of a number of folks on the PBX in a Flash forums including our old pal, Joe Roper, there is an alternative that folks have been wrestling with for over two years. The combination of Hylafax, Avantfax, and IAXmodem is a compelling open source solution if you don’t need T.38-compatible faxing.1 The drawback has been the learning curve to install all the components and get them working reliably together. Well, for those using Incredible PBX 1.8 with PIAF-Purple and Asterisk 1.8, today we have a newly minted installation script that is simple enough that even a monkey can use it. If you know your own email address and your local area code AND you can find the Enter key on your keyboard, you are fully qualified to perform today’s installation. It’ll take you under 5 minutes! We’ve also got a nice little surprise for you toward the end of this article.
Prerequisites. You’ll first need to install the latest version of PBX in a Flash with the PIAF-Purple (Asterisk 1.8) payload. Then sign up for a free Google Voice account and install Incredible PBX 1.8. You’ll find complete installation instructions for everything here. Can you just wing it and run this installation script on a garden-variety Asterisk 1.8 machine? No. And the reason is that all of these components have dependencies which are too complex to cover in a 5-minute article. You might want to have a look at the A-Fax Project which is where we started. Suffice it to say, the combination of PIAF-Purple and Incredible PBX 1.8 provides the ideal platform on which to install Incredible Fax. If you prefer to do-it-yourself, by all means have at it. We lost about 10 years worth of hair even starting with the work of a dozen very talented Linux gurus who have been wrestling with this for over two years! But, hey, YMMV! We never claimed to be the sharpest tool in the shed. 😉
Installing Incredible Fax. Once you have your Incredible PBX 1.8 platform up and running, adding Incredible Fax is a stroll in the park. Just log into your server as root and issue the following commands. If you’ve downloaded Incredible PBX in the last few days, the script may already be on your system. In this case, just type /root/incrediblefax.sh to run it.
cd /root
wget http://incrediblepbx.com/incrediblefax.sh
chmod +x incrediblefax.sh
./incrediblefax.sh
After checking to make sure Incredible PBX 1.8 is installed, the script will prompt you to enter an email address where incoming faxes should be delivered. Then all of the necessary components will be installed after which the Avantfax install script will be run. With the exception of entering your local area code when prompted to do so, the correct response to every other question is to press the Enter key if you live in the U.S. or Canada. Don’t "improve" anything if you expect the end product to work reliably. For those outside North America, you’ll need to also make the usual adjustments to account for your country and city codes.
Avantfax has its own security model, but we’ve grown to appreciate the Apache authentication model which is built into PBX in a Flash so it’s been incorporated into Incredible Fax as well. When the install completes, just reboot your server to get everything working. On the PBX in a Flash web GUI, there will be a new Admin icon for Faxing. Or you can access Avantfax with a browser by going to http://serverIPaddress/avantfax. When prompted for your username and password, use maint and whatever your maint password happens to be. These can be reset with passwd-master. Literally everything has been preconfigured in Avantfax to get you going. Here’s a 3-minute video to show you how easy it is. Just don’t forget to reboot once the install completes.
If you want to be able to print to fax from Windows-based machines, then you’ll need to make one addition. Click on the small Toolbar icon in the upper right corner of the AvantFax home screen and choose New User from the pull-down Menu. For the user, enter Fax for the Name, fax for the Username, a secure password for Password, and an email address that is DIFFERENT from the one you used to set up Incredible Fax. Check the boxes for User Can Delete Faxes and User Can Fax From Any Modem. Finally, check the boxes for all four IAXmodems. Then click the Save button to add this new user.
A Word About Reliable Faxing. Suffice it to say that analog faxing over VoIP trunks is something less than ideal. If you want reliable analog faxing, then you’ll need a PSTN line from your favorite local telephone company. It doesn’t need any fancy add-ons like CallerID which doubles the price in many cities. Then you’ll need a properly configured analog telephone adapter (ATA) with at least one FXO port to support your Ma Bell phone line. Our favorite is the OBi110 which also can double as an additional Google Voice trunk for your PBX. But an SPA3102 will work equally well. It just costs more and gives you less.
Now that we’ve covered the obligatory warnings… will Incredible Fax work with a pure VoIP connection? Absolutely. We do it all the time. Is it flawless? No. Are there certain providers that are better than others? You bet. Do some providers not support faxing at all? Correct. Based on our 5+ years wrestling with this, here’s our recommendation. First, you’ll need a DID (i.e. phone number) from one of our recommended providers to handle inbound faxes. With the latest release of Asterisk 1.8, you no longer need a DID dedicated to faxing. In other words, you can use the same DID to receive incoming voice calls as well. The good news is that pay-as-you-go DIDs are dirt cheap. Some providers such as voip.ms offer DIDs for under $1 a month with 1¢ per minute calls. VoIP.ms also has unlimited inbound calling DIDs for under $4 a month. Other providers whose trunks we have found work reliably for VoIP faxing include Vitelity (see our special sign up deal below), Axvoice, Teliax, VoIPMyWay ($45 for first year with unlimited outbound and inbound calling with a local DID), and Future-Nine2. Google Voice trunks are hit and miss. We’re batting about .250 in our testing with Google Voice lines. Bottom Line: If VoIP faxing doesn’t work after you complete the install, it’s probably the fault of your VoIP trunk, not the setup. To make absolutely sure, connect a standard fax machine to an extension using an FXS telephone adapter and send a fax to that extension from the Avantfax web interface. You’ll find it works every time!
Configuring FreePBX for Incredible Fax. Here are the steps you’ll need to complete to get analog faxing working reliably with FreePBX. First, set up an account with one of the companies we’ve mentioned above. With voip.ms, create a subaccount on their site with credentials to use with the DID you purchased to link to that subaccount.
Unless you’re using today’s release of Incredible PBX, you’ll need to activate FreePBX’s Fax Configuration Module if you want to take advantage of Asterisk 1.8’s fax detection capabilities. It didn’t work reliably in previous Asterisk 1.8 releases. This module already is either available or already installed on your server. In the FreePBX GUI using a browser, choose Tools, Module Admin and then click on Fax Configuration. A drop-down list will provide several choices. Choose either Install or Enable depending upon the version of Incredible PBX you currently are running. Then click the Process button and finally Reload the settings when prompted.
Unless you installed Incredible PBX today, you’ll need to create a SIP trunk for your new provider in FreePBX using the credentials you set up on the provider’s web site. The VoIP.ms template now is included in Incredible PBX so you can just edit the existing one to add your credentials. And, at least with VoIP.ms, you can set the outbound CallerID to anything you like (as long as it’s legal). Unless you want a knock at your door, we wouldn’t recommend using the main number at the White House. Then put all of the settings below in the Outgoing Settings PEER Details where 1234567 is your main account number, subacctname is the name of the subaccount you created, and atlanta is your closest voip.ms server location:
username=1234567_subacctname
type=friend
trustrpid=yes
sendrpid=yes
secret=subacctpassword
nat=yes
insecure=port,invite
host=atlanta.voip.ms
fromuser=1234567_subacctname
disallow=all
context=from-trunk
canreinvite=nonat
allow=ulaw
For the registration string, it should look like the following. If you’re planning to only use the trunk for outbound faxing, then you can leave off the trailing DID number.
username:password@atlanta.voip.ms:5060/10-digit-DID
In addition to setting up the Trunk for your provider, you’ll also need to create an Outbound Route for sending faxes out through this trunk AND an Inbound Route to receive incoming faxes on the DID you purchased from your provider.
For the Outbound Route, we recommend setting the Dial Pattern with a prefix not otherwise used on your Incredible PBX so that you can make fax calls easily by dialing this prefix. For example, on our sample system, we used 7 so that fax calls could be made by dialing 7 plus a 10-digit number in the U.S. and Canada. Here’s how our Outbound Route for VoIP.ms looks in FreePBX, and the latest Incredible PBX release already has it in place as shown below:
For the Inbound Route, you want to specify the DID from your provider which must match the 10-digit number you affixed to the end of the trunk registration string above. If you don’t want to share this number for voice and fax calls, then simply direct these inbound fax calls to the Fax Custom Destination. Extension (329 spells F-A-X) also can be used to process incoming faxes and route them to your email address as well as the Avantfax web GUI.
Our experience suggests that using a single trunk for both voice and fax delivery is hit and miss so you may wish to consider adding an additional trunk just to support faxing. You’ll find the templates for adding a second Google Voice trunk in the /tmp directory, and complete instructions are available on the PIAF Forums. We’ve also provided preconfigured trunk settings for both Vitelity and VoIP.ms if you’d like to try those options as well. Just plug in your credentials and configure an inbound route to map incoming faxes to the Fax Custom Destination.
AvantFax in a Nutshell. Here’s a quick summary of the main features in the AvantFax web GUI. You can access the GUI by pointing a browser to the IP address of your server + /avantfax. After you enter your maint account name and maint password, the following screen will display with your Inbox. As noted, all of these incoming faxes also will be emailed to the account you set up when you ran the Incredible Fax install script.
The icons to the right of each thumbnail fax let you View, Rotate, Download PDF, Reply to Fax, Email PDF, Add a Note, Archive the Fax, and Permanently Delete the Fax.
At the top of the screen just to the right of Inbox is the option to Send a Fax. Here you’d specify the phone number to dial. Don’t forget the 7 and then a 10-digit number. Next you can attach a document from your local disk. Finally, fill in the blanks for the Fax Cover Sheet, and then click Send. Your fax will be on its way. You can monitor the progress of the fax transmission by clicking on Outbox. It’s also a good idea to fire up an SSH session to your server and run asterisk -rvvvvvvvvvv to monitor the first few calls to be sure all is well in Incredible FaxLand.
Where to Go Next. HylaFax and AvantFax are very mature open source products with a huge international following. We apologize for focusing primarily on U.S. and Canadian users today, but anything is possible with this software. The first piece you probably will want to tackle is adding Print to Fax capability on your Windows machine. The software you’ll need can be downloaded here. You’ll find excellent documentation on the setup by visiting the PBX in a Flash Forum. One little footnote for those using Windows 7. Microsoft and Apple are back to their old tricks so there are no Apple postscript print drivers in Windows 7. We’ve had equally good results using Dell’s 3100cn PS driver. Incidentally, there’s a similar print-to-fax utility for Mac OS X, but it’ll set you back $36. Here’s the link. HylaFax also maintains a terrific resource list for those that want additional goodies for PCs, Macs and Linux systems.

Changes in PBX in a Flash Distribution. In light of the events outlined in our recent Nerd Vittles article and the issues with Asterisk 1.8.4, the PIAF Dev Team has made some changes in our distribution methodology. As many of you know, PBX in a Flash is the only distribution that compiles Asterisk from source code during the install. This has provided us enormous flexibility to distribute new releases with the latest Asterisk code. Unfortunately, Asterisk 1.8 is still a work in progress to put it charitably. We also feel some responsibility to insulate our users from show-stopping Asterisk releases. Going forward, the plan is to reserve the PIAF-Purple default install for the most stable version of Asterisk 1.8. As of June 1, Asterisk 1.8.4.1 is the new PIAF-Purple default install. Other versions of Asterisk 1.8 (newer and older) will be available through a new configuration utility which now is incorporated into the PIAF 1.7.5.6.2 ISO.
Here’s how it works. Begin the install of a new PIAF system in the usual way by booting from your USB flash drive and pressing Enter to load the most current version of CentOS 5.6. When the CentOS install finishes, your system will reboot. Accept the license agreement, and choose the PIAF-Purple option to load the latest stable version of Asterisk 1.8. Or exit to the Linux CLI if you want a different version. Log into CentOS as root. Then issue a command like this: piafdl -p beta_1841 (loads Asterisk 1.8.4.1), piafdl -p 184 (loads Asterisk 1.8.4), piafdl -p 1833 (loads Asterisk 1.8.3.3), or piafdl -p 1832 (loads Asterisk 1.8.3.2). If there should ever be an outage on one of the PBX in a Flash mirrors, you can optionally choose a different mirror for the payload download by adding piafdl -c for the .com site, piafdl -d for the .org site, or piafdl -e for the .net site. Then add the payload switch, e.g. piafdl -c -p beta_1841.
Bottom Line: If you use the piafdl utility to choose a particular version of Asterisk 1.8, you are making a conscious decision to accept the consequences of your particular choice. We would have preferred implementation of a testing methodology at Digium before distribution of new Asterisk releases; however, that doesn’t appear to be in the cards. So, as new Asterisk 1.8 releases hit the street, they will be made available through the piafdl utility until such time as our PIAF Pioneers independently establish their reliability.

FreePBX Backdoor Passwords Pose Asterisk Security Threat
Whether it’s forgetting to change a default password or not removing an additional password that you didn’t even know existed, some new revelations this week about FreePBX security are worth a minute of your time. There’s more disappointing news. The bad guys are getting smarter and much more dangerous.
If you’re new to Asterisk®, FreePBX® is the terrific, web-based graphical user interface that turns Asterisk into a user-friendly PBX that even mere mortals can use. It is bundled as part of every Asterisk aggregation including PBX in a Flash, trixbox, Elastix, and Asterisk Now. With the exception of PBX in a Flash, you may not know it’s there, but it is.
Years ago when FreePBX was in its infancy, the developers set up a way that administrators could still get into their system even if they forgot their administrator password. Typing admin:admin as the username:password combination basically gave you the keys to the castle in the default FreePBX install. That worked great in the days before folks exposed their systems to direct Internet web access which is a really BAD IDEA by the way.
Some of the aggregations shipped with a default username and password combination of maint and password. And for visually-impaired users, an automatic installer was crafted which set a default password of passworm. While users were encouraged to change these default passwords, many unfortunately didn’t heed the advice. According to one unnamed provider that recently saw a spike in illegal calling activity, his attempt to log in to some of his customer’s systems using password as the administrator password yielded a list of 50 vulnerable systems in under an hour!
And then there was this week’s Elastix revelation that the developers had embedded an additional backdoor password in their distribution that very few knew about… except the bad guys unfortunately. According to Xorcom:
It recently came to our attention that it is possible to login to the Elastix server unembedded FreePBX Web interface (http://address/admin) with user name ‘asteriskuser’ and password ‘eLaStIx.asteriskuser.2oo7’. The user name and password are the same user name and password used by FreePBX to access the ‘asterisk’ MySQL database. They are defined in the parameters AMPDBUSER and AMPDBPASS in the /etc/amportal.conf file.
What could possibly go wrong? Well, everything! Over the past few years, what typically happened with these vulnerable systems was that the buy guys obtained an extension password and began making free calls on your nickel until you checked your FreePBX call log or received your phone bill. That was then.
Here’s the latest bad guy scenario. The intruder logs into your FreePBX GUI using the default administrator password using a very sophisticated script which extracts all of your extension numbers, all of your trunk credentials, and, of course, all of your passwords. The script then hides a BOT on your server that "phones home" whenever any change is made in your account names or passwords. Finally, rather than using your server to make calls, the bad guys now use their own servers with your provider credentials to make free calls. So the first notice you receive of the intrusion is when your credit card is maxed out because you stupidly chose credit card auto-replenishment when you set up your VoIP account with your favorite provider.
SO… how do you fix it? Well, first you need to check whether your system is vulnerable. Using a browser, attempt to log into FreePBX at http://yourIPaddress/admin and use the following username:password combinations:
admin:admin
admin:password
admin:passworm
maint:admin
maint:maint
maint:password
maint:passworm
wwwadmin:password
wwwadmin:wwwadmin
wwwadmin:admin
asteriskuser:eLaStIx.asteriskuser.2oo7
Be aware that on some systems using Fail2Ban such as PBX in a Flash, three consecutive failed logins may lock you out of your system for a lengthy period of time. On these systems, we recommend you first stop Fail2Ban: service fail2ban stop. Don’t forget to restart it after your testing: service fail2ban start.
If you gain access to your system using any of the above credentials and the web interface your server is exposed to the Internet, then you’ve got a problem. Do NOT just change your password thinking all is well. As mentioned, your new credentials are likely being transmitted to the bad guys before you can say "I’m S-C-R-E-W-E-D." Instead, you should reformat your drive, contact all of your trunk providers and change your credentials. Then reinstall a NEW system using your new credentials AND new extension passwords. DON’T FORGET TO CHANGE YOUR DEFAULT PASSWORD! On PBX in a Flash and Incredible PBX systems, it’s easy. Just log into your server as root, enter the command passwd-master, and answer the prompts. Think up a very secure password… as if your bank account depended on it. It does! Finally, read our Primer on Asterisk Security. Be safe!

Tips, Tricks & Apps to Get the Most Out of Your iPad 2
Rather than providing another glowing review of the iPad 2®, we thought it might be more helpful to sketch out the daily use potential of this incredible device based upon our experience and that of our 10-year old daughter. Yes, we’re one of the 30% who purchased an iPad 2 having already owned a number of first generation iPads. With double the RAM and nearly double the processing power of the first generation device, the one cautionary note that potential purchasers should heed is don’t buy the $499 model. Our daughter has survived a year with a $499 iPad only to find it completely full when she attempted to load Garage Band. And you will want Garage Band which is a storage hog by iPad standards. That’s not to suggest that Katherine’s iPad hasn’t served her well. She has almost 150 applications plus substantial collections of photos and music. What she doesn’t have is movies and video clips. With the addition of two cameras on the iPad 2 as well as Camera, AutoStitch, Movie, and Photo Booth apps and once you see what’s possible with iMovie, you’ll be begging for more storage capacity. Keep in mind that your storage capacity choice is irrevocable! There’s no way to add more storage later unless you buy a new device. And there’s no external storage other than removing apps and data through the iTunes interface. Perhaps more than anything else, that’s why the absence of a microSD slot on the iPad 2 is both a significant shortcoming and a huge disappointment.
The other suggestion we would offer to first-time iPad 2 purchasers is this. Get organized early. What we mean is decide early on how you’re going to use the 10 screens to organize your applications. Before the year is out, you will use all 10 screens assuming your bank account survives. At least now you can also create folders within a screen if you run out of room. Here’s our methodology, and it has served us pretty well. Screen 1 is reserved for the apps we use every day. The other screens are reserved for categories of applications: business, news and books, social, drawing and graphics, music, games, location-based services, and system/network management. If you’re a big gamer, artist, or musician, you may want to reserve two screens for your favorite category. The point is to spend a little time up front deciding how to organize applications. And, fortunately, you can move things around with the iTunes interface down the road so long as you leave one screen available for reorganizing.
You can also place six apps at the bottom of the display, and these are accessible from all 10 screens. Here’s where you’d want your browser, email or Gmail buttons, App Store, and Settings. That leaves you two more must-have apps. If you play music all the time, you’d probably want the iPod app. If you look at Photos all the time, you’d want the Photo app. But you get the idea, use Screen 1 for Daily Use Apps and the 6 bottom slots for your must-have at all times apps. If you don’t heed this advice, then you’ll find yourself having to search for apps on Screen 0 every time you want to use an application.
Favorite Apps. That brings us to our favorite apps. For ease of reference, we’ll cover these in the same way they are organized on our iPad 2. And, we’d love to hear about your favorite apps, too. Just post a comment. In the Daily Use category, here’s our list:
Calendar
Contacts
Mail
Maps
Videos
FaceTime
Camera
Photo Booth
EyeTV
YouTube
Hulu Plus
SlingPlayer
NetFlix
Bria
Travelin’ Man
OBiON
Pandora
Pulse News
Flipboard
iSWiFTER
Most of the above applications are self-explanatory, but we’ll mention a few. If you have a Mac, then EyeTV is a must-have addition. It lets you play and record all your favorite TV shows. Removing commercials from a one-hour show is about a 2-minute click-and-drag operation. And it’s incredibly easy to export your favorite recordings in either iPhone or iPad format. So long as iTunes is running on your Mac desktop, you can play your recordings or live TV at any time using either a WiFi or 3G network connection. SlingPlayer does much the same thing (only worse) with no recording capability, but it works with Windows machines as well as Macs, and it’s a standalone device. The Netflix app lets you stream movies and TV shows to your iPad for $7.99 a month, and it supports 6 simultaneous devices including many current generation HDTVs. OBiON is the VoIP app that lets you make free Google Voice calls in the U.S. and Canada using your $49 OBi device. You can read all about it here. If you have an Asterisk® PBX, then you’ll want Bria and our Travelin’ Man app for secure, remote, and free SIP communications. Finally, there’s the new iSWiFTER app which brings Flash video back from the dead on the iPad platform. It’s free for a limited time and, believe it or not, it’s available in the App Store.
Books & News. We spend every morning at the breakfast table with the Books & News page on our iPad. Here’s our list:
Kindle
iBooks
Friendly (Facebook)
Twitterific
AccuWeather
ABC News
ABC Player
CBS News
CNBC RT
CNN
Huff Post
Newsy
NYTimes
News Pro
USA Today
WSJ
Wash Post
The Daily
TV Guide
Tweetdeck
We don’t watch much Faux News which has become more akin to Incitement TV. We really hoped The Daily would be different. It’s not. But… to each his own.
Business Apps. This is kind of a catch-all page for stuff we use frequently as well as some apps we’ll probably never use again. Here’s our list:
iMovie
Keynote
Pages
Notes
Bento
Sorted
2Do
Todo
Zenbe Lists
Voice Memos
aNote Lite
Dictation
Due
FlipTime XL
MobileNoter
Pad Info
PaperDesk LT
News Rack
GoodReader
textPlus
Of all the ToDo applications that are available (and we’ve tried most of them), we like Todo the best. But, for quick reminders, you can’t beat Due. GoodReader, Keynote, and Pages are must have business apps, and iMovie is every bit as good as the app on the Mac. It’s about perfect for an on-the-go, need-it-in-a-hurry project.
Navigation & Wi-Fi Apps. When we’re on the road or looking for a WiFi Hot Spot or good place to eat, here’s our list:
CoPilot HD
Charts & Tides
Navionics Marines
ShipFinder HD
GPS Drive HD
GPS HD
Hurricane HD
UrbanSpoon
Epicurious
Where To Eat
ZAGAT
Zillow.com
WiFiGet HD
Dash Four
Mifi
World Atlas
Skobbler
SpeedBox
WiFon
Trapster
GPS navigation on the roads is hit and miss on the iPad. Nothing comes close to Google Maps navigation. CoPilot could be a contender except for the outdated maps and copy protection paranoia. On the water, both Charts & TIdes and Navionics Marine are fantastic. We compared both of them to a $10,000 Nav system on a very fine boat only yesterday. There was virtually no difference in the information available with the exception of the radar-enhanced features. If you’re always shopping for real estate, there is no finer app than Zillow, period. If you’re in to fast cars, there is no finer app than Trapster.
Games. Last but not least, everybody needs a diversion once in a while. Here’s a list of some of our favorite iPad games:
Game Center
GearedHD
Frogger
Foosball HD
AirCoaster
Angry Birds
Asphalt 5
JirboBreak
Doons HD
ElectroRacer
FarmVille (WAF)
Hit Tennis 2
iFooty
Pac-Man
Pinball HD
RealRacing HD
RealRacing GTI
Snowboarding
Checkers HD
Wacky Circus HD
This will probably be the category that changes the quickest with the new lightening-fast graphics and dual core processor on the iPad 2. Stay tuned!

Google Dips Its Toes in the Icy SIP Waters… and Retreats
In case you missed it, Google announced at the end of last week that it will discontinue support of Gizmo5 on April 3. Many of us suspected this was the death knell for Google support of SIP given the popularity of its recent Gtalk enhancements to Google Voice. Well, not so fast! As Todd Vierling pointed out on his blog this past Saturday, Google has quietly added outbound SIP support to reach any Google Voice number. So, assuming your Google Voice number is 678-123-4567, anyone in the world can now call you via SIP by dialing +16781234567@sip.voice.google.com.
For those using Asterisk® and FreeSwitch systems , here’s what you need to do immediately. Register all of your Google Voice numbers in the ENUM systems so that other Asterisk and FreeSwitch systems worldwide can connect with you using your new Google SIP URI without any communications charges. This also means that SIP phones such as the Nortel 1535 Color Videophone using services such as sip2sip.info can call you for free. And all they’ll need to do is dial your 10-digit Google Voice number!
To sign up for ENUM service, go to both e164.org and enumplus.org and register your 10-digit Google Voice number. Be sure to use the syntax shown above for the SIP URI (including the + symbol), or the calls will fail. It only takes a minute to register. ENUM is implemented for outbound calls by default in all Incredible PBX and Orgasmatron builds. So, just by registering your Google Voice number with these two sites, it means every ENUM-enabled server can place free SIP calls to your Google Voice number via ENUM before using any other outbound trunk for which there might be a charge.
Of course, everyone won’t register their Google Voice number with the ENUM services. So how do you call those folks via SIP without incurring charges for the call? For those that install Incredible PBX (beginning yesterday), it’s automagic. Just dial any 10-digit number, and Incredible PBX will attempt to place the call via SIP before falling back to Google Voice. The call processing is instantaneous so don’t worry about call delay. Remember, we’re living in a Digital World.
FreePBX Setup. If you have an existing FreePBX-based Asterisk system or an earlier release of Incredible PBX, here’s how to retrofit your system to support free SIP calling to Google Voice numbers. Whenever an Asterisk server attempts to place a SIP call, it sends a SIP Invite packet to the receiving server. In the case of Google, if the number is not one of theirs, you’ll immediately get a Congestion message from FreePBX. In the FreePBX design, this means that the attempt to place the outbound call will drop down to the next available trunk in the current Outbound Route. So the trick here is to create a custom trunk to handle the SIP calls to Google. And then we’ll add that trunk above your existing trunks in the Outbound Route that handles calls matching 1NXXNXXXXXX and NXXNXXXXXX. So the recommended Trunk Sequence in your Default Outbound Route would look like this:
1. ENUM
2. google-sip
3. gvoice
4. vitel-outbound
5. OtherProvider
Using a web browser, open FreePBX and choose Setup, Trunks, Add Custom Trunk. Create the new Google-SIP Trunk so that it looks like the following. Don’t forget the 1 Prepend and + Dial Prefix entries!
Click Submit Changes to save your entries and then reload FreePBX when prompted.
Now choose Setup, Outbound Routes, and choose your Default outbound route. Modify the Trunk Sequence so that it matches what was outlined above. Click Submit Changes to save your entries and then reload FreePBX when prompted.
You’re done. Enjoy your new SIP-based Google Voice calling addition.
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 Google Voice number. Enjoy!
March 8 Update. Well, that was a quick dip. Beware the Ides of March! It was almost exactly two years ago that Google shut down SIP connectivity the first time. Hopefully, we’re not in for another two year wait. Read our original article about this and have a chuckle. But it looks like they’ve done it again. To restore your system to normal functionality, remove the Google-SIP trunk from your Outbound Route and be sure to delete your Google Voice numbers from the SIP registries at e164.org and enumplus.org. To suggest this is short-sighted (not to mention monetarily wasteful) would be an understatement. But perhaps Google wasn’t prepared for the onslaught of delighted users. Let’s hope so. 🙄
March 16 Update. It’s working again this morning! But now it’s not morning, and we’re dead in the water once more. Did we mention this might qualify as E-X-P-E-R-I-M-E-N-T-A-L?? See the comments below for up-to-the-minute updates.
Security Reminder. We mentioned this two years ago, but it’s worth repeating since it still has not been addressed. Google protects phone access to your Google Voice account with only a 4-digit PIN. When unanswered calls roll over to their voicemail system, anyone has the option of pressing * to be prompted for this PIN. It only takes 10,000 calls at most to guess any PIN, and that doesn’t take very long with SIP and an automated dialer. Once someone has your PIN, in addition to listening to your voicmail messages, they also can press 2 to place an outbound call to anywhere in the world… on your nickel. So… don’t load up your account with your entire life savings unless you don’t mind losing it. 🙄

Incredible PBX 1.8: New OpenVZ and Cloud Editions
Another exciting week in the Asterisk® community with the introduction of Asterisk 1.8.2 last Friday. It's now the official PIAF-Purple payload so you can simply download the current ISO to take it for a spin. Most of the pesky bugs in Asterisk 1.8.0 and 1.8.1 now have been addressed. Let us know if you find some new ones.
While the Asterisk Dev Team has been hard at work on Asterisk 1.8.2, we've turned our attention to the cloud and VoIP virtualization. We have three new products to introduce today. The first lets you install PIAF-Purple with Asterisk 1.8.2 using a new OpenVZ template. The second lets you run Incredible PBX 1.8 as a virtual machine using the new PIAF-Purple 1.8.2 OpenVZ template. Finally, we'll show you how to run Incredible PBX 1.8 in the cloud with hosted VoIP service from RentPBX.com for $15 a month with a free local phone number and free Google Voice calling in the U.S. and Canada. So let's get started.
Using the OpenVZ PIAF-Purple Template. If you haven't heard of OpenVZ templates before, you've missed one of the real technological breakthroughs of the last decade. Rather than wading through the usual 30-minute ISO installation drill, with an OpenVZ template, all of the work is done for you. And it's quick. You can build a dozen PIAF-Purple systems using an OpenVZ template in about 15 minutes with a per system cost of less than $50. See Comment #2 below for an extra special Dell half-price server deal this week. And it's incredibly easy to then tie all of these systems together using either SIP or IAX trunks. Just follow our previous tutorial. For resellers and developers that want to try various Asterisk configurations before implementation and for trainers and others that want to host dedicated Asterisk systems for customers, the OpenVZ platform is a perfect fit. Read our original two-part article to get up to speed on Proxmox, virtualization, and IPtables with OpenVZ. Then continue on here.
Thanks to Darrell Dillman (aka dad311 on the PIAF Forums), there already is a 64-bit OpenVZ template of PIAF-Purple with Asterisk 1.8.2. Just download the template to your Desktop and then, using the Proxmox console, choose Appliance Templates, Upload File to upload the OpenVZ template into your Proxmox server platform. Once installed, you can build Asterisk 1.8.2 virtual machines to your heart's content... in less than a minute apiece. Just choose Virtual Machine, Create to create a new virtual machine using the OpenVZ template you just uploaded. In the Configuration section, choose OpenVZ for the Type and pick your new OpenVZ template from the pulldown list. Fill in a Host Name, Disk Space maximum (in GB), and (root) Password. The other defaults should be fine. In the Network section of the form, change to the Bridged Ethernet (veth) option which means the VM will obtain its IP address from your DHCP server. Make sure your DNS settings are correct for your LAN. Here's how a typical OpenVZ creation form will look:
Once the image is created, start up the virtual machine, wait about 70 seconds for the system to load, and then click on Open VNC Console. Asterisk will be loaded and running. You can verify this on the status display. You can safely ignore the status messages pertaining to IPtables assuming iptables -nL shows that IPtables is functioning properly. With the exception of text-to-speech (TTS), you now have a PIAF-Purple base platform running Asterisk 1.8.2 and FreePBX 2.8. Be sure you always run it behind a hardware-based firewall with no port exposure to the Internet.
Before you do anything else, run passwd-master to secure the passwords for FreePBX GUI access to your system. Don't forget!
If you're planning to install Incredible PBX below or if you don't need text-to-speech on your system, you can skip this next step which gets 64-bit TTS installed. Otherwise, here are the commands to get it working:
cd /root
./install-flite
Note to Our Pioneers. To those that tested the new OpenVZ template this past week, THANK YOU! Be advised that we now have incorporated several of the recommended tweaks which were documented in the PIAF Forums. The install procedure outlined above explains the new behavior of the slightly improved OpenVZ template which now is available for download. We recommend you switch.
Asterisk CLI Change. Finally, just a heads up that (once again) the Asterisk Dev Team appears to have changed the default behavior of the Asterisk CLI. With Asterisk 1.8.2, if you make outbound calls after loading the CLI, you will notice that call progress no longer appears in the CLI. To restore the standard behavior (since Moses), issue the following command: core set verbose 3. 🙄
Installing Incredible PBX on OpenVZ Systems. We won't repeat the entire Incredible PBX article here. If you want the background on the product, read the latest article. To get everything working with an OpenVZ system, there are only three steps:
1. Set Up Your Google Voice Account
2. Run the Incredible PBX VM Installer
3. Configure a Softphone
Configuring Google Voice. You'll need a dedicated Google Voice account to support The 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 why take the chance. Keep this account a secret!
We've tested this extensively using an existing Gmail account, and inbound calling is just not reliable. The reason seems to be that Google always chooses Gmail chat as the inbound call destination if there are multiple registrations from the same IP address. So, be reasonable. Do it our way! Set up a dedicated Gmail and Google Voice account, and use it exclusively with The Incredible PBX. Google Voice no longer is by invitation only so, if you're in the U.S. or have a friend that is, head over to the Google Voice site and register. If you're living on another continent, see MisterQ's posting for some tips on getting set up.
You must choose a telephone number (aka DID) for your new account, or Google Voice calling will not work... in either direction. Google used to permit outbound Gtalk calls using a fake CallerID, but that obviously led to abuse so it's over! You also have to tie your Google Voice account to at least one working phone number as part of the initial setup process. Your cellphone number will work just fine. Don't skip this step either. Just enter the provided 2-digit confirmation code when you tell Google to place the test call to the phone number you entered. Once the number is registered, you can disable it if you'd like in Settings, Voice Setting, Phones. But...
IMPORTANT: Be sure to enable the Google Chat option as one of your phone destinations in Settings, Voice Setting, Phones. That's the destination we need for The Incredible PBX to work its magic! Otherwise, all inbound and outbound calls will fail. If you don't see this option, you may need to call up Gmail and enable Google Chat there first. Then go back to the Google Voice Settings.
While you're still in Google Voice Settings, click on the Calls tab. Make sure your settings match these:
- Call Screening - OFF
- Call Presentation - OFF
- Caller ID (In) - Display Caller's Number
- Caller ID (Out) - Don't Change Anything
- Do Not Disturb - OFF
Click Save Changes once you adjust your settings. Under the Voicemail tab, plug in your email address so you get notified of new voicemails. Down the road, receipt of a Google Voice voicemail will be a big hint that something has come unglued on your PBX.
Running The Incredible PBX Installer. Log into your server as root and issue the following commands to set up The Incredible PBX:
cd /root
rm incrediblepbx18-vm.x
wget http://incrediblepbx.com/incrediblepbx18-vm.x
chmod +x incredible*
./incrediblepbx18-vm.x
passwd-master
When The Incredible PBX install begins, you'll be prompted for the following:
Google Voice Account Name
Google Voice Password
Google Voice 10-digit Phone Number
Gmail Notification Address
FreePBX maint Password
The Google Voice Account Name is the Gmail address for your new dedicated account, e.g. joeschmo@gmail.com. Don't forget @gmail.com! The Google Voice Password is the password for this dedicated account. The Google Voice Phone Number is the 10-digit DID for this dedicated account. We need this if we ever need to go back to the return call methodology for outbound calling. For now, it's not necessary. But who knows what the future holds. 🙄 The Gmail Notification Address is the email address where you wish to receive alerts when incoming and outgoing Google Voice calls are placed using The Incredible PBX. And your FreePBX maint Password is the password you'll use to access FreePBX. You'll actually set it by running passwd-master after The Incredible PBX completes. We need this password to properly configure the CallerID Superfecta for you. By the way, none of this confidential information ever leaves your machine... just in case you were wondering.
Now have another 5-minute cup of coffee, and consider a modest donation to Nerd Vittles... for all of our hard work. 😉 You'll find a link at the top of the page. While you're waiting (and so you don't forget), go ahead and configure your hardware-based firewall to support Google Voice. See the next section for what's required. Without completing this firewall configuration step, no calls will work! When the installer finishes, READ THE SCREEN just for grins.
Here's a short video demonstration of the original Incredible PBX installer process. It still works just about the same way except there's no longer a second step to get things working.
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!
Before you do anything else, run passwd-master again to resecure the passwords for FreePBX GUI access to your system. Don't forget!
Firewall Configuration. We hope you've taken our advice and installed a hardware-based firewall in front of The Incredible PBX. It's your phone bill. You'll need to make one adjustment on the firewall. Map UDP 5222 traffic to the internal IP address of The Incredible PBX. This is the port that Google Voice uses for phone calls and Google chat. You can decipher the IP address of your server by logging into the server as root and typing status.
Extension Password Discovery. If you're too lazy to look up your extension 701 password using the FreePBX GUI, you can log into your server as root and issue the following command to obtain the password for extension 701 which we'll need to configure your softphone or color videophone in the next step:
mysql -uroot -ppassw0rd -e"select id,data from asterisk.sip where id='701' and keyword='secret'"
The result will look something like the following where 701 is the extension and 18016 is the randomly-generated extension password exclusively for your Incredible PBX:
+-----+-------+
id data
+-----+-------+
701 18016
+-----+-------+
Configuring a SIP Phone. There are hundreds of terrific SIP telephones and softphones for Asterisk-based systems. Once you get things humming along, you'll want a real SIP telephone such as the $50 Nortel color videophone we've recommended above. You'll also find lots of additional recommendations on Nerd Vittles and in the PBX in a Flash Forum. If you're like us, we want to make damn sure this stuff works before you shell out any money. So, for today, let's download a terrific (free) softphone to get you started. We recommend X-Lite because there are versions for Windows, Mac, and Linux. So download your favorite from this link. Install and run X-Lite on your Desktop. At the top of the phone, click on the Down Arrow and choose SIP Account Settings, Add. Enter the following information using your actual password for extension 701 and the actual IP address of your Incredible PBX server instead of 192.168.0.251. Click OK when finished. Your softphone should now show: Available.
Incredible PBX Test Flight. The proof is in the pudding as they say. So let's try two simple tests. First, let's place an outbound call. Using the softphone, dial your 10-digit cellphone number. Google Voice should transparently connect you. Answer the call and make sure you can send and receive voice on both phones. Second, from another phone, call the Google Voice number that you've dedicated to The Incredible PBX. Your softphone should begin ringing shortly. If not, make certain you are not logged into Google Chat on a Gmail account with these same credentials. If everything is working, congratulations!
Here's a brief video demonstration showing how to set up a softphone to use with your Incredible PBX, and it also walks you through several of the dozens of Asterisk applications included in your system.
Solving One-Way Audio Problems. If you experience one-way audio on some of your phone calls, you may need to adjust the settings in /etc/asterisk/sip_custom.conf. Just uncomment the first two lines by removing the semicolons. Then replace 173.15.238.123 with your public IP address, and replace 192.168.0.0 with the subnet address of your private network. There are similar settings in gtalk.conf that can be activated although we've never had to use them. In fact, we've never had to use any of these settings. After making these changes, save the file(s) and restart Asterisk: amportal restart.
Running Incredible PBX in the Cloud. We've saved the best for last today. For many folks, you may want to experiment with VoIP technology without making a hardware investment and without having to master the intricacies of managing your own server and network. That's what Cloud Computing is all about. And we've searched far and wide to find you the perfect platform. As with many of you, one of our top priorities is always cost. While many providers were willing to provide Nerd Vittles with a few sheckles for pitching their product, only one stepped forward with a price point that we think is irresistible. And, for the record, we waived any compensation other than a few test accounts to get things working properly, so that all of the savings could be passed on to you! So here's the deal. $15 a month gets you your own PIAF-Purple server in the cloud at RentPBX.com. Just use this coupon code: BACK10, pick an east coast or west coast server to host your new system, choose the PIAF-Purple 1.7.5.5.4 install option, set up a username and very secure password, and you're off to the races. Once your account is established, here's the 5-minute procedure to install the special RentPBX-edition of Incredible PBX to begin making free calls in the U.S. and Canada through Google Voice.
Begin by Configuring Google Voice as outlined above. Then log into your RentPBX account using SSH and the port assigned to your account. For Windows users, download Putty from here. The SSH command will look something like this:
ssh -p 21422 root@209.249.149.108
Issue the following commands to download and run The Incredible PBX installer for RentPBX:
cd /root
wget http://incrediblepbx.com/incrediblepbx18-rentpbx.x
chmod +x incrediblepbx18-rentpbx.x
./incrediblepbx18-rentpbx.x
passwd-master
Now just follow along in the Incredible PBX virtual machine tutorial which we've included above. Remember that your new Incredible PBX is sitting directly on the Internet! So don't forget to run passwd-master when you finish the install, or your system is vulnerable. Ours was attacked within minutes!
Securing Your RentPBX Server. With the exception of our WhiteList application, everything is working on your RentPBX server. While we continue to work on the WhiteList component (reread this section of the article in a week or so to get the latest updates), you need to secure your system to avoid endless hack attempts on your SIP resources. Here's how. First, write down the IP addresses of your RentPBX server and your home network. Second, print out your existing IPtables configuration. The file to print is /etc/sysconfig/iptables. Third, make a backup copy of the file. While logged into your server with SSH, the easiest way is like this:
cd /etc/sysconfig
cp iptables iptables.bak
Now we need to edit the iptables file itself: nano -w iptables. Then search for the line that contains 5060: Ctrl-W, 5060, Enter. At the beginning of this line, add # to comment out the line. With the cursor still on this line, press Ctrl-K then Ctrl-U twice. This will duplicate the line. Move to the second commented line and remove #. Use the right cursor to move across the line to --dport. Then insert the following using the IP address of your RentPBX server, e.g.
-s 229.149.129.248
Be sure there's at least one space before and after the new text. Now duplicate that line with Ctrl-K and Ctrl-U twice. Change the IP address on the second line to the public IP address of your home or office network. Repeat this process for every IP address where you intend to use a SIP phone connected to your RentPBX server. Make additional entries for your SIP providers as well. If you want to sleep better, you can make similar changes to the SSH port entry to restrict it to your home/office IP address. It's the line immediately above the 5060 entry. Ditto for port 80 which is web access. Be very careful here. A typo will lock you out of your own server! When you're finished, save the changes: Ctrl-X, Y, Enter. Then restart IPtables: service iptables restart.
As always, we strongly recommend that you not put all of your VoIP eggs in one basket. Google Voice does go down from time to time. Vitelity is a perfect complement because the costs are low and you only pay for the service you use. A discount sign up link is below. And Vitelity has contributed generously to both the Nerd Vittles and PBX in a Flash projects. So please support them. Enjoy!

Introducing: New PBX in a Flash Installer for USB Flash Drives
Since inception, one of the goals of the PBX in a Flash project has been to provide an install option that works reliably from a USB Flash Drive. This has become even more important as many of the newer netbooks have dropped CD/DVD drive support to conserve space and reduce cost. Just in time for Santa, we’re pleased to announce that, thanks to the Herculean efforts of bmore on the PIAF Forums, a USB Flash Drive installer is now available. This new build obviously is E-X-P-E-R-I-M-E-N-T-A-L. As with all PIAF 1.7.5.5 installs, you get your choice of Asterisk® and FreePBX® payloads with this new installer:
- Gold – Asterisk 1.4.21.2 with FreePBX 2.6
- Silver – Latest Asterisk 1.4 Release with FreePBX 2.6
- Bronze – Latest Asterisk 1.6 Release with FreePBX 2.6
- Purple – Latest Asterisk 1.8 Release with FreePBX 2.8
Here’s the 5-minute drill to get your bootable USB flash drive loaded with the PIAF installer. Once you get that far, hop over to the Nerd Vittles Installation Tutorial for PIAF 1.7.5.5 or The Incredible PBX for details on the install process.
Prerequisites. To get everything installed on your USB Flash Drive, you’ll obviously need at least a 1GB Flash Drive. HINT: 2GB flash drives may actually be cheaper! And we can tell you that Kingston DataTraveler models may be problematic. Reportedly, the Corsair GT and Kingston 102 models work fine. YMMV! Please report your results in a comment below. Next you’ll need to download the latest, greatest version of UNetbootin from SourceForge. There are versions for Windows and a number of flavors of Linux. Finally, you’ll need to download the Flash-Only ISO of PIAF 1.7.5.5.5 from SourceForge.
Creating USB Flash Drive. Step #1 is to partition and format your USB flash drive as a FAT32 device. On Windows 7 and Vista machines, you can format the drive as a DOS device, and it will automatically format it as FAT32. Once the device is properly formatted, run UNetbootin and select the Disk Image option. Then, with the ISO on your Desktop, choose the PIAF-17555-flashonly.iso from the pull-down menu. Make certain that the destination device is your USB flash drive. Then choose OK to begin. Do NOT reboot your machine when prompted to do so. You don’t really want to install PIAF on this same computer! Remember to Eject the flash drive on Windows machines before removing it.
If your Windows machine happens to crash at the end of the USB Flash install process (ask us how we know 🙂 ), all may not be lost. Restart your Windows PC, insert the flash drive again, go through the Windows error fixup procedure when prompted, and then open the drive with Windows explorer. If the only file missing from the root folder is syslinux.cfg, you’re in luck. Just download the file from here and copy the file into the top directory of your flash drive. Done!
Using the USB Flash Installer. When using the new flash installer, remember that we need to boot your new machine from the flash drive. On most newer Atom-based computers, you accomplish this by inserting the flash drive, turning the machine on, and then pressing F12 during the boot sequence to choose the boot device. You’ll just have to watch the screen of your new computer to see if some other key is used to pull up the boot selection screen. If all else fails, you can adjust the boot sequence in the BIOS settings to boot first from the USB device. If you change your BIOS boot sequence, just remember to remove the device when the initial install of CentOS completes and the reboot sequence is initiated. If instead you again see the initial PIAF install screen warning you that your disk is about to be erased, then remove the flash drive and reboot the machine once again. Then choose the PIAF payload you’d like to install. Enjoy!
And Merry Christmas!
