Asterisk faces FreeSwitch

Asterisk is well-known, but the open-source IP PBX
FreeSwitch is winning favor in some circles, says ZDNet’s Dave Greenfield.

FreeSwitch gets kudos for cleaner code and better
implementation of some types of features. 
Expected to be released this week, Version 1.0.1 improves the code
stability and adds both automatic speech recognition and text to speech to the
code. 

Open source developers and enterprise users are finding love
with FreeSwitch. SIPfoundry is using FreeSwitch as the basis for a new open
source conferencing server. Implementation of call monitoring and busy lamp
field (BLF), voice mail, and call parking reportedly are all much better in
FreeSwitch. The platform supports writing IVRs in Lua, Javascript, Python, Perl
and a built-in XML.

A bigger challenge for all open source projects will be the
ability to integrate PBX functionality with business applications through web
services.
