[asterisk-dev] Jitter Buffer

[Pavel Jezek]

I tried SIP-IAX call, but still not any info about funtional SIP 
jitterbuffer  :'(
no console SIP jitterbuffer message, nothing in /tmp, nothing in 
asterisk/messages
also it would be nice, if we have consistent jb config (jbenable, 
jbforce etc...) for IAX and other channels
and also some generic way how to debug/monitor jittterbuffer: like "core 
jb debug", instead of iax2 jb debug (or instead of sip jb debug etc.)

SVN-branch-1.4-r45928M (with jitterbuffer/plc patch: 
http://bugs.digium.com/view.php?id=8189)

my sip.conf

jbenable=yes
jbforce=yes
jbmaxsize=2000
jbimpl=fixed (adaptive tried too)
jblog=yes

iax.conf
jitterbuffer=yes
forcejitterbuffer=yes
maxjitterbuffer=3000
;maxjitterinterps=5
resyncthreshold=-1
