It's not a GM problem, but a problem with the other end. It's not
unusual (although it's very, very frustrating) for some H.323
implementations to refuse a terminal capability set if it fails to
recognise any of the codecs. IIRC, NetMeeting will refuse to connect if
it receives a connection offering T.38.

This is not just a H.323 problem either - I had exactly the same problem
with a SIP carrier only a few weeks ago that could only do G.711 but
would refuse to connect at all if either iLBC or Speex was offered as an
option.

The only way to avoid this problem is to disable the offending codecs 
(as you have done). The final codec is displayed somewhere GM.

NetMeeting supports the "callto" URL scheme, which is also supported by
OpenH323 (and hence GnomeMeeting). See the following URL for more
