Hi Philip, Also make sure you have the following lines in iax.conf:
jitterbuffer=yes dropcount=1 ; ...to drop at most 0.5% of VoIP packets Also make sure you provisioned it using ULAW (not ADPCM). It can easily be verified by adding these lines in iax.conf: disallow=all allow=ulaw ...and don't allow any other codecs. With 120 ms latency you might not get away the echo either way... Our IAXy customers does not experience any echo with this setup, but it might not be of importance in this case, since their latency is not that high.

Don't test with any cordless/wireless phone or headsets. I've seen a problem where a customer was using a Plantronic wireless headset and was complaining about echo on our network. I got him to use the phone's handset instead of the headset and the problem was gone!!!! Good luck, Stephan Monette Unlimitel inc.

I am brutally angry with digium especially since I am a reseller and have sold alot of there gear. So if anyone can help me figure out the problem stated below that would be most appreciated by the many people out here with Iaxys There problem is there is occasionally mild to really bad echo. this has nothing to do with the pstn , this portion has been debugged to death secondly it happans when there is an iaxy to iaxy call, so this dosnt even touch the pstn !!!! ive checked latencys and they all seem to be 120ms and less 120 being the worst, jitter is usually non exsistent to 0003ms so that is absolutly nothing. The system is using the latest asterisk as of a few days ago 1.0.x branch and is an amd 2800+ running on centos 2.6 Can anyone please point me in the direction to fix this issue before i just blacklist digium hardware.
