Hi,

Can somebody tell me what is the scope of capability negotiation in SIP?
Take this scenario,
                               A --------------------Invite with H.264
codec------- >  B
                               A <------------------200 OK with H.261
codec-----   A

What will be the codec used in this case?

I believe I have assumes that SIP sends only one codec once rather than a
set of them! So I expect the call to get rejected!!!

Am I correct?? And waht kind of message is sent to indicate that capability
negotiation has failed?


Regards,

Vineet Menon
