[Asterisk-Users] Asterisk on FreeBSD-5.4 RELEASE : H323 audio problem

[Sigit Priyanggoro]

Dear All. 
 
 
I have installed Asterisk-1.0.6 on FreeBSD-5.4 RELEASE via port, so the chan_h323.so modules already included. 
 
 
When i try the SIP channel, asterisk works fine. In this case, i use the XLite softphone as client, i can hear the voice transfered through clearly. Asterisk is good!! :D 
 
 
The problem is when i try the H323 channel, the voice cannot be transferred through. I have already use the NetMeeting and SJPhone for clients when debugging. The clients can call each other, but when the call answered, there wasn't any voice. So the problems was with audio, not at call setup. 
 
 
In the CLI mode, i have the h.323 debug and h.323 trace enabled, and there is no problem in call setup. 
                                          ^^^^^^^^^^^^         ^^^^^^^^^^^ 
 
When i try the h.323 show codecs .... it is empty!! Is this the cause?? 
                       ^^^^^^^^^^^^^^^^^^^ 
When i try the h.323 show tokens ..... it is empty too!!! Is this also the cause?? 
                       ^^^^^^^^^^^^^^^^^^^ 
 
But when i try the show codecs the codecs was showed completely. Looks like the codecs was fine. 
                              ^^^^^^^^^^^^^ 
 
Is this a bug, or my configuration fault??? 
 
I have tried Googling all this week, but there is no answer, so help me please! :D
