style="font-size: 10pt; font-family: Arial;">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 3<sup>rd</sup> 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 3<sup>rd</sup>
user (the one with audio breaking up), the Jitter is relatively high
(0627ms)
and the Lag is relatively low compared to the others (00012ms).<o:p></o:p></span></font></p>

the same LAN, so can’t quite
understand the differences.<o:p></o:p></span></font></p>

I'm having the same issue; I'd love to know how to actually diagnose
the issue.<br>
I assume there is somewhere on the voip-info.org wiki about this?<br>
