<br>
<br>
I have noticed that there have been some discussions recently about
problems with IAX2 and jitterbuffer.
<br>
We are heavily using these components in our production systems, but so
far we have not noticed any issues with the latest versions of
Asterisk.
<br>
However, if people have hit problems, then we would be definitely
interested in hearing about them and maybe helping solve them.
<br>
<br>
So I would like to ask anybody who experienced such problems to please
speak up and provide as many details as you can. </blockquote>

If bridging ilbc SIP -> Zap channels, transcoding is done before
frames are queued to jitter (depends on SETUP direction) and thus
interpolation is not applied. I've made nasty workaround in our
production system in channel.c so translating is always applied to Zap
channel. <br>

issues. We have a tool that can be used to stress test chan_iax and,
by extension, anything in Asterisk. We could probably use it to hit
bugs that show up only under high load.

Cheers,
