Hi all,
I want to know whether the capability
exchange can be done more than once in a single conference.
I mean initially suppose I am having G.711 and
H.261 codec capabilities...
Now after some time suppose I want to use G.722
instead of G.711 without disconnecting the session, so is it possible and
how..
Moreover I am having a doubt regarding the
Gatekeeper. It is fine that intially when endpoint sends ARQ to the Gatekeeper,
it requests for badwidth (i.e. audio codec b/w, video codec b/w and data channel
b/w), please correct me if I am wrong.
Now during the conference if I want to have more
bandwidth then endpoint will send BRQ message to GK. But I want to know whether
the user has to specify what bandwidth it needs or that is hidden in the
underlying protocol... My intetntion is that suppose initially I have all the
audio/video/data channels (If T.120 is there) opened, but now I just want to
start the whiteboard facility then obviously I'll have to request the
bandwidth... So how that can be done.. Who'll do that
Thanks for any help
Ashu.
