Is it possible to somehow get "compatible" Speex codex that work with
GnomeMeeting and with NetMeeting?

What exactly is the difference between an ACM and OpenH323 codex?
Only some bytes in the header?  How can I make them "compatible"?

MS-GSM works, but the voice quality is very bad compared to Speex 8 kBit/s,
so I still try to get Speex interoperating on both platforms.
