Asterisk Voicemail to Email solved with Postfix

Editor's Note:  Here is a follow-up Asterisk help article from my good friend & VoIP Engineer Matt Birkland at VoiceIP Solutions.

A while back I wrote an article for Asterisk VoIP News about routing loops occurring from misconfigured DNS(or lack there of). My article was about routing loops caused by Asterisk attempting to send mail outside the network when the mail server destination is internal.

Why Wait? Build Your Own Skype Gateway to Asterisk

As the world awaits the much-hyped Digium commercial offering of a Skype for Asterisk gateway, we began exploring existing alternatives last week that provide the same functionality at what will no doubt be considerably less cost. The Gizmo5 solution is darn-near perfect for those that need a quick solution and don't mind spending $20 a year to let someone else wrestle with the technical complexities that invariably accompany maintenance of cross-platform gateways such as this one.

Putting Asterisk TeleYapper to the Test

Solving Asterisk PBX Voice Mail to Email Name Resolution Issues

Note:  Matt Birkland (Network Engineer) is on a roll by sending in another Asterisk Help article about Email Name Resolution on internal networks.
One of the most popular features in Asterisk is the Voice Mail to email feature.  It's fairly straight forward to set up as far as Asterisk is concerned, but many people (including myself) have run intoo a situation where the Asterisk server is on the same internal network as the mail server.  When Asterisk resolves , it attempts to send the mail to the Fully Qualified Domain Name (FQDN).

Time-Zone Processing with Asterisk - Part I

Last year, I took a trip to Asia. To stay in touch, I carried a GSM world phone, capable of receiving telephone calls in the countries I was visiting. The capability to receive calls with the same mobile phone number I use at home while halfway across the world seemed incredibly cool-at least until the first call came in!
Mobile phones hide the location of the phone, which cuts both ways. A colleague had decided to call me in the middle of the day on a Friday, which had awakened me very early on Saturday morning, because the phone "hid"my faraway location from him.

Asterisk: Dealing with IRQ's on T1/PRI Lines

The one constant in every Asterisk Integrators life is the pain of dealing with telco's.  The main problem with telco's is the disparity between the tech support. 
Sometimes you open a ticket with the guy that can detect an issue in hours.  Usually it takes days of bitching and finger pointing to actually get someone on site.  Many times a Telco insist their PRI/T1's are funtioning, but your Asterisk server is dropping frames.  As a consequence, popping, cracking, lost calls, static and echo occur.  This is a really bad place to be, if you spent hours trying to convince your boss about the merits of Asterisk.

Setup MV-370 GSM Gateway with Asterisk

Note: Found this handy help article on how to setup a approx. $150 GSM gateway from ebay to work with your Asterisk PBX.  Internally on our office we are going to be deploying a GSM gateway to get a couple employees' cellphones without the big bills and the ability to test this concept out.

"The GSM gateway MV-370 is manufactured by
It's main interest in comparison with other gateways is that it is GSM to SIP (not FXS), so voice quality is very good.
Another point of interest is the price (around $150 on ebay).
With that gateway properly configured, you are able to receive calls from GSM to Asterisk (including DISA) and to give calls from Asterisk to GSM network.

How to install Asterisk Business Edition on Fedora Core 5

Note:  Matt Birkland, a local Seattle Asterisk PBX Integrator sent in this article after working through some troubles installing ABE on the Fedora Core 5 Operating System.  I hope this helps out anyone that has been having trouble.  Please email (comments[at] in any comments or questions and we will be sure to pass them along and make updates as needed.
Full Article:
Many people may be in a situation like myself where they need specific driver support for a raid array for their Asterisk server.  In my case this requires me to use Fedora core 5Fedora Core 3 and 4 is supported by Digium, but not 5.  However I called Digium to confer and a tech told me that they will attempt to support any issue they can replicate on a supported system.

They will not support the installation itself.  Luckily I figured it out, this procedure will likely work on Fedora Core 6 as well, but I have yet to confirm this.
