[GnomeMeeting-list] Audio channel connection problem

[Eduard Kriegler <kriegler sun ac za>]

Hi all

I've noticed a potential bug and would like to know if anyone else have 
seen this as well:

Basically, when making a video call from a PC with both audio recording 
and playback hardware to another PC with only audio recording software, 
gnomemeeting is constantly trying to open an audio transmit channel on 
the caller PC. Obviously this channel cannot be opened because the 
called PC doesn't have playback hardware. (The audio channel from the 
called PC back to the caller PC is opened and works fine though)

I first noted this behavior while writing my own video conferencing 
software (based on OpenH323), but confirmed that the problem exists in 
gnomemeeting as well (one can see this happening by looking at GM's 
general history - Tools->General History). I'll paste the log from the 
caller PC below. The PC receiving the call doesn't show anything about 
trying to open the audio channel in its log.

Both PCs are running SuSE 9.1 and GnomeMeeting 1.0.1.

Has anyone else noticed the same behavior? What can be done to fix it? 
Is this perhaps more of an openh323 bug than a gnomemeeting bug? Any 
comments/ideas welcome!

Thanks in advance,
Eduard
