I think that they just need people sending them emails saying "Company X
demonstrated G.723.1 interoperability with Company Y".

Some people have started to send those to Stephen Casner [casner at acm.org].

He's looking for people who implemented the early version of H.263-1996 and
GSM-HR and GSM-EFR.

If you do, respond, because they will remove the payload type...

Francois,

I believe you are correct.  However, I am not familiar with how the IETF
determines
"interoperable implementations".  Is is simply a matter of vendors reporting
with whom
they interoperate or is there some IETF-sponsored interop event that needs
to be
attended?

 Guys,This payload type = 4 for G.723.1 has been in H.225.0 for many years.
Don't we have many interoperable H.323 products using PT=4 for G.723?Won't
it be a major interoperability problem if this payload type is removed from
the A/V specification?????> -----Original Message-----
