I’m setting up a simple PBX for conferencing and have the following problem with Asterisk.
When I connect using IAX2 (client is kiax, but I tried others too), I lose incoming audio after 1 to ~15 seconds. My config is this:
asterisk: 10.254.254.16
softphone: 10.31.41.20
no NAT between them
When I connect using SIP, there’s no such problem. Using SIP is however not an option, because of NAT (which will be used, I’m using no-NAT just now for testing)
I ran tcpdump during the call. While there was audio, I saw packets sent both ways. When the audio stopped, there were no more packets from asterisk (10.254.254.16) to the softphone (10.31.41.20). I could hangup the call and the call was properly terminated (i.e. signalling works fine).
Asterisk is version 1.6.2.2-1ubuntu2 (current package in Ubuntu 10.04 beta distribution).
my iax.conf:[general]
bandwidth=low
disallow=lpc10
jitterbuffer=yes
forcejitterbuffer=no
minregexpire = 30
maxregexpire = 600
autokill=yes
[peto]

IAX2 debug log (there was only about 300ms of audio, then silence):
