[asterisk-users] 1.8.3 - IAX - echo - jitterbuffer

[sean darcy]

I'm using iaxagent on a Droid X to connect by IAX to 1.8.3 at the 
office. 1.8.3 has sip phones. The audio is fine on the Droid X side. On 
the office side, they hear an echo of _their_ speech, not mine.

The office uses sip-providers generally without any echo problem.

Where do I start to figure this out? How do I narrow it down? Can I 
figure out if it is an iaxagent problem? Could using jitterbuffer cause 
this?

Thanks for any help.
