Hey,
I have UAC that registers to a UAS, after registration the UAS sends me an OPTIONS request, what should I answer it?
only the audio
media streams?
Update I:
Allow me to explain myself better... if I want to invite someone to a session I USE the INVITE method and negotiate the
media then, for that specific session. But once I register to the
server, and it asks me for OPTIONS, then what should I supply, everything my client supports? once I answer it would it deduce that every INVITE I would request from now on would use these medias? or would I need to supply new
media with every request?
Update II:
Hi Wiz,
I was in the process of building a negotiation system, so i tried it out and replied the UAS here is the sort dialog we had:

This response caused the
server to stop sending me the options request, does this means I can only use these parameters with the
server now? or as you said, it does not matter?
Thanks,
Adam.
