[linux-audio-user] net telephony

Looking for point to point telephony ideas ...

- each end has a half-duplex sound card, Linux/OSS and mic/speaker,
- maximum bandwidth is 28800 bps, outback Australia analog lines,
- Debian is preferred distribution, but we can cope with builds,

While I could spend a few weeks researching all the packages that 
mention "phone" or "H.323" or "SIP", I'd rather ask some experts who
have tried it already, so as to use my time wisely.

I have looked already at speakfreely, linphone, and speex.  speakfreely
appears to be reasonably complete, but not easy to use.  linphone had a
host of dependencies that I was unable to resolve.  speex as an encoder
and decoder works really well on voice recordings, but I've no idea yet
if it will help.

I have found the OpenH323 project, but the clients listed on their page
are all Windows.

Reply direct to me; I realise that the list is primarily focussed on 
higher quality sound than mere telephony.  ;-)
