At the risk of seeming impolite, the problems that Asterisk has with
H.323 say far more about Asterisk than it does about OpenH323.

If we assume that GM+SIP will use OPAL, then I can answer some of these
questions:

OPAL will support all of the audio codecs that are supported by OpenH323,
which includes all of the above.

OPAL will support video (although it does not currently).

I don't know what codecs are supports by Messenger, so I can't answer
this question.

I'll let Damien answer this one :)
