The OpenH323 Project
far from simple, but ohphone is the best developed app so far
have not used it but it's come a long way fast
OSIP - Open SIP Stack Library
finally, and open SIP stack in C!
VOCAL - The Vovida Open Communication Application Lib
Open source stacks in C++, but rather big and resource hungry
Asterisk - Open Source PBX
Extensive development effort
Bayonne - the GNU Project IVR Software
Been around a long time, widest range of card support
PreViking - Telephony Middleware
Excellent framework for building telephony services.
Also, you may be intersted in the Linux Telphony API
(LTAPI). This API was originally designed for low density linux
telephony applications and is in the kernel now (GPL). To date,
only Quicknet card drivers are supported, but I am developing a
driver for Voicetronix cards now and there is at least one other
new telephony card with drivers under development.
And, there's an open hardware voice T1 card available with a PRI
library even. See:
A new discussion list has started to look at getting a
consistent linux telephony API that works across all these
cards. The current LTAPI is geared towards low density devices,
but may need modification if high density (T1 and up) supprt is
to work. You cna join this list by sending email to
majordomo at lists.herlein.com
with the line "subscribe ltapi <your address>" in the message
We're trying to get an informal BoF together for linux telphony
enthusiasts at the LinuxWorld in San Francisco this
month. Details on that to follow, since there is no more space
for an official Bof at the conference.
I also have an SDP and an RTP library under development, but my
development time has been rather reduced lately.
