[Asterisk-Users] delay problem in h323

[Rattana BIV]

Hi,   I have a delay between two H323.   Netmeeting1 --------- |            |                              | gnuGK | ----------- [asterisk-oh323]---- | Asterisk | Netmeeting2 ----------|            |   Netmmeting 1 call Netmeeting 2. When Netmmeting 1 speak Netmeeting 2 receive the voice without delay. But in the other way I have 3 secondes delay. In oh323.conf  I set jittermin and jittermax to 20, the ipTos=lowdelay. I try to find where I can delete the delay. Does anyone have a tip ?     Best Regards Rattana
