asterisk users - Aug 2004 - After RC1 upgrade, temporary loss of voice

I just upgraded to RC1 from a two-three month old CVS , and noticed that
during IAX2 calls to my service provider there are periods (usually less
than 10 seconds long, minutes apart) during which the caller can not hear
me, but I can hear the caller fine.
 
Inter-office calls (SIP-to-SIP) does not appear to have this issue.
 
Has any other users experienced this?

Hmm, I've been experiencing the same today.
Though I'm not on RC1, I'm on HEAD-07/07, and I just recently
implemented
g729. Which is more sensitive to dropped packets.

Otherwise I've seen this occur when one party have network traffic on his 
side. The other party cannot hear them but the one with busy connection 
could. 

Guess it depends on in what direction the heavy traffic is going.

I had no traffic on my side, though. Also, I'm going to turn on QoS on my 
router, to prioritizing VoIP, that might make all the difference since RR 
does support it.

Yup,

We're experiencing it here on at 1.0-RC1 upgrade. SIP to SIP calls are
rock solid uLAW/aLAW, but IAX2 to NuFone (and assumably other
IAX2<->IAX2 connections) are giving the breakups.

Not QoS related as our uLAW/aLAW connections transit the same routes as
the IAX2 traffic (using GSM or iLBC). Will try to find the commands to
update to the latest CVS source for 1.0-RC1. Are the appropriate CVS
commands on the Wiki?

I just posted my findings on this -- I am seeing the same problem, I didn't 
see your postings until just now...  so it does appear to be something with 
RC1 and IAX2.

Nufone upgraded to RC1 and we're seeing the problem (My * servers were 
20040604, now 20040806 CVS HEAD).

Steve's posted a temporary solution under the thread I started (search for 
TEMPORARY FIX RC1 in the archives) -- basically disable jitter buffer on the 
machine you're converting from TDM to IAX.  In my setup:

home* - IAX2 - colo* - IAX2 - nufone

I disabled the jitter buffer on home* (and office*, which also connects to 
colo*).

Please refer to the other thread for more details, but this temporary 
workaround cured the gappy audio on my system.

Andrew
