thanks for that. I am surprised.

Steve, what voip codec do you use?
If you can select, use G723 (6.3 kbit/s)

yep, 64kBit is fine with GnomeMeeting. You should use Speex8k though, as
there's a huge protocol overhead that needs to be added to that number
of x.y kBit/s.. (many small packets)
Empirically Speex8k works fine and MS-GSM might also do. The G.723 does
require a hardware extension and is not available with pure software.
Feel free to search the GnomeMeeting archives for details on
configurations. ;)

ahh, but I do not have VoIP. I am planning still.

I must recommend against using G723 unless you are in a very bandwidth starved
but high reliability situation. VOIP is extremely time sensitive, and the
latency involved in compression greatly reduces your margin for error. G711
uses more bandwidth (64k per call is a reasonable figure, but it depends on
packetization), but will be considerably more forgiving to jitter.
