[Asterisk-Users] SOLVED: IAX jitter / clocking problem

[Pavel Jezek]

I found my mistake jiterbuffer=yes vs. jitterbuffer=yes  ;-)
currently I have this settings, and seems this working quite well,
only sometimes gaps appears, when jitter changes too much eg. >500ms - 
jitterbuffer probably can't adapt so quick,
maybe good idea to set some minimum jitterbuffer value, but this is not 
possible in current new jitterbuffer implemenation

jitterbuffer=yes
forcejitterbuffer=yes
maxjitterbuffer=1500
maxjitterinterps=10
resyncthreshold=2000
