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. ;-) -- James Cameron mailto:quozl@xxxxxxxxxxxxx http://quozl.netrek.org/
