How Many Asterisk Deployments?


I know that there is no way to determine an exact number, or even a close number, but does anyone know a ballpark figure of how many Asterisk deployments are out there worldwide? How about the percentage of Asterisk PBX's compared to the total number of PBX's out there? Do our friends at Digium ever think about things like this?

Looking For PRI Card With Automatic Fail Over


I have a customer where we are putting an Asterisk PBX in front of a legacy (non-VoIP) PBX. One of the requirements it that the Asterisk PBX have 2 PRI ports (one towards the legacy PBX and one towards the carrier) with the ability to go to pass through should the Asterisk PBX (software or hardware level) fail.

I did not see this feature in the Digium, Sangoma, Allo, or OpenVox cards.

Does anyone know of a card that will do this? I know that Digium has an external box (the…

Asterisk 13 FAX


Hello team! I’m planning to add fax functionality to my PBX. From research it seems that there is 2 options: spandsp and Digium. I lean towards Digium app, licensing is fine. However, they don’t have download for v13 Should I just download their version for v12 Asterisk? Any other suggestions on what to use, what works best? I have a pretty good plan on what I’m going to do but unsure which one to pick. Callcentric is my SIP provider and it supports T.38 Thanks Ivan --

Recommended Changes To The Binary Packaging System


I think the way Digium has structured the binary packages could use a major change. I rely on the binary packages rather than compiling by source because my systems are managed by an automated CM tool (I use Ansible but those using Chef or Puppet will face the same problems) and for security reasons. I use the CentOS packages.

Some issues with the current package structure are: - It installs unneeded repositories. The asterisknow package install 12 repositories, of which I use at most 4 (2 asterisk and 2 digium) - It changes which repositories are enabled and disabled. - It…

Call Transfer Fails - Not A Valid Extension


We have a plain vanilla installation of AsteriskNOW using Digium D40/50 phones. All transfers are failing from any source to any extension with the message "that is not a valid extension". Does anyone have any ideas about where to begin looking for the source of that error?

Broadsoft - Asterisk Interop


Greetings to all. I am not sure of this is a "user" question or a "business" so apologies in advance if it should be asked in the business list.

A client of mine has a UK branch that is served by a provider that uses the Broadsoft solution. I want to create a sip trunk from a remote asterisk pbx to the client.

The provider claims that Broadsoft has a strict "protocol" on what "devices" can connect on their network and asterisk is not listed

Does anyone know if asterisk (1.8 to be more precise) has passed interoperability tests with Broadsoft ?

Asterisk Not Starting After YUM Update


Hi List,

it feels silly, but here I am.

My Asterisk box is useless, after running a long delayed yum update (CentOS box).


A few details on the box:

cat /etc/redhat-release CentOS release 5.10 (Final)

arch i686

uname -a Linux hermes 2.6.18-371.4.1.el5 #1 SMP Thu Jan 30 06:09:24 EST 2014 i686 athlon i386 GNU/Linux

asterisk -r Asterisk, Copyright (C) 1999 - 2010 Digium, Inc. and others.


Starting Asterisk very verbosely seems to load the dialplan, but at some point I get a segmentation fault. This is new to me!

Fax Buffer Overflow Detected



I'm running Asterisk 1.8.15-cert3 with the newest version of spandsp. I've even tried unloading that and using Digium's FFA module but I receive the same error on an outbound transmission:

[2014-02-06 14:35:14] ERROR[19066]: udptl.c:294 encode_open_type: UDPTL (SIP/XXXXXXXXXXX_outbound-00000000): Buffer overflow detected (59 + 127 > 175)

I only get this with one specific upstream provider. Has anyone seen this before? Any help at all would be greatly appreciated.
