[Freeswitch-users] audo sync issues with record_session to mp3

[Frank @ Impact]

We have the same problem.  We are running git from 12/30/11.  our aleg is a
sip channel coming to FS and the bleg is a sip channels leaving FS.  

I noticed this problem really when we started using mp3 instead of
wav.  With wav, it really was not noticeable for us in a 10-15minute call.
But with mp3, we notice it after just 2-3 minutes. By 10 minutes, it is so
far out of sync, it sounds like 2 different calls.

The relevant dialplan is

	  <action application="hangup"/>
        </condition>

What's on the other end of each leg? That might help us figure this out.
