In my case I don't have a T1 or even a fractional T1, but cable
and have
noticed that choppy calls can be reduced by adding tos settings.
Like:
Tos=lowdelay|throughput|reliability

New Jitterbuffer
Tuning
I have now set the "resyncthreshold" to
-1, to turn it off. I have also
set the "maxjitterbuffer" to
2000.
I still received 10 complaints of choppy calls today on Asterisk
1.2.4
versus only 1 complaint on Asterisk 1.07.

Hi Adam
> 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
thanks,
yusuf
