(Test call originated from C7960 with g711.)I noticed the same thing. Jitter buffer apparently is broken, and has always been. I was advised to say jitterbuffer=no in iax.conf, but I swear it's better with it set to yes and then executing "iax2 set jitter 250" in the CLI. At least it was before I cvs up'd. :-) Jeremy (of NuFone fame) has his jitterbuffer=no on his servers and since he's my VOIP provider I tend to just try and match his setup in terms of IAX2 anyway. I dunno, I do agree with you that it seemed better a while ago. Regards, Andrew
Check bug #1220, which involves IAX even though the subject doesn't tell you. Mark has been working quite a lot to try to fix it. /O
Are there open problems/issues with iax2 and jitter (quality)? Just upgraded to today's dev cvs about an hour ago, and it seems the iax conversations are lower quality then a month or two ago. iax2 show firmware says version 13. (Test call originated from C7960 with g711.) Using the demo as an example, iax2 show channels Peer Username ID (Lo/Rem) Seq (Tx/Rx) Lag Jitter Format 216.207.245.8 (None) 00002/00011 00002/00003 00000ms 0033ms GSM The sound is very choppy, frequently here echo (repeated words), etc, and it seems to be happening with other iax calls besides the demo. I've not specified any maxjitterbuffer size (or any other iax quality parameters). Are parameters now required when they might have defaulted in earlier releases? Rich
