Hi there I have a question regarding IAX jitter. I have 3 users on a LAN dialing into a Meetme conference on an Asterisk box which is also hosted on the LAN. I have set jitterbuffer = no and tos = lowdelay. Now, for 2 of the users the audio is fine, but for the 3rd user there is intermittent break up in the audio when they are receiving. I have had a look at "iax2 show channels" and for the first 2 users (those with no audio problems), the Jitter is low (0006ms), and the Lag is relatively high (00070ms). For the 3rd user (the one with audio breaking up), the Jitter is relatively high (0627ms) and the Lag is relatively low compared to the others (00012ms). All of the users are on the same LAN, so can't quite understand the differences. Any explanations / ideas would be much welcome.

Thanks Steven I'm having the same issue; I'd love to know how to actually diagnose the issue. I assume there is somewhere on the voip-info.org wiki about this? JD I'm in the same boat, although I'm only using IAX2 for connectivity to my provider. The phones themselves are SIP, but some users (really should be read all users, but at different times) experience bad audio - described as "cutting-out" from the remote party. My user is heard correctly by the remote party but the remote party is bad to my user. Doesn't seem to matter whether it's inbound or outbound.
