> After many days of playing with the new jitterbuffer and trunking options for IAX2, I have finally received almost acceptable quality.  I am receiving 5-8 complaints a day of calls "breaking up" from both the customer and agent sides.  What I have discovered is that in most of these cases, the new jitterbuffer performed a resync during the call.  Currently, I have the resyncthreshold, and all other jb parameters at their default levels  The traffic is running over a fairly high latency WAN connection between Canada and Atlanta (IAX2, ILBC).  Idle ping times run about 85ms.

I am interested to know why you are using ilbc, n why not g729 ot g723 
or speex.  What is the size of the WAN connection.  How many calls are 
you running over this link.  I just need to see how others are fairing 
with IAX2 over WAN links, as I am the final stages of testing on my side
