Hi,
I have 2 asterisk servers connected over wan using iax2 tunnel mode.
Are there any know bugs/issues using jitter buffer enabled with iax2 trunk on asterisk-1.4.22? I am getting following strange errors during the calls and audio quality is seriously effected. I have DTC400B transocder card & using g729 codec between asterisk servers.
my iax.conf general section is below:
[general]
bindport=4569
bindaddr=10.10.10.10
iaxcompat=yes
tos=ef
autokill=yes
language=en
jitterbuffer=yes
forcejitterbuffer=yes
maxjitterbuffer=1000
maxjitterinterps=100
resyncthreshold=1000
disallow=all
allow=g729
allow=gsm
error messages:

I opened a ticket with digium customer support team & still waiting for resolution. Please suggest.
