I am experiencing choppy sound when I bridge from a SIP peer to an IAX peer. I am running Asterisk 1.4.13 on a 2.6.22.9 kernel (Fedora). I am experiencing choppy sound from the SIP peer to the IAX peer but not vice-versa. I know that this is not a bandwidth issue because I don't have choppy sound (with the same codec) when bridging IAX->IAX peers or SIP->SIP peers. My timing source is ztdummy. Does anybody have any ideas on the possible source of the problem? -- Muiz Motani <muiz at askaritech.com> Askari Technologies

Can you check any firewall logs for dropped packets?

[asterisk-users] Choppy Sound On Bridging From SIP->IAX
I had the same problem doing SIP -> IAX, 1.4.19.1 as well as the last 1.4.22 In my case I was trying to do FAX and the blips were breaking lots of the faxes. My solution was to switch to T.38 over SIP and (cross my fingers) the problems haven't came back so far. I don't know the source of the problem, except that going to the latest (at that time) 1.4 did not solve it. I did switch to 1.6 because I wanted to try out the new app_fax and I've been very pleased with the results. But keep in mind I also dropped the SIP -> IAX conversion at the same time, so I don't have a good data point. Now you have me curious, and I think I'll try doing the SIP -> IAX conversion just to see if 1.6 made it any better. Maybe 1.6 would solve your problem too?
