[asterisk-users] jitterbuffer SIP-IAX possible?

[Pavel Jezek]

please, can somebody tell us, if currently used jitterbuffer 
implementations (iax or sip w/ jb patch) are really working/usefull if 
jitter is frequently changing between 10-1000ms (on cdma connection)?
I have really big problems with using jitterbuffer between two asterisks:
- with iax2, I can't set some minimum jitterbuffer (or turn off adaptive 
jitterbuffer)
- when bridged sip-iax calls, sip jitterbuffer is probably not activated 
at all  :-(
please send some your experience, thanks
PJ

my config (iax.conf):

[general]
jitterbuffer=yes
forcejitterbuffer=yes
maxjitterbuffer=4000
;maxjitterinterps=15
resyncthreshold=-1

(sip.conf)
jb-enable = yes
jb-force = yes              
jb-max-size = 2000
jb-resynch-threshold = 1000
jb-impl = fixed
jb-log = yes
