Third party registration/group registration

[Agboh, Charles]

sorry,...

Hi Chris,

My undstanding of "third-party" registration is the same as yours.   But, in
some applications a registration by the IWF may not be on its own behalf.
H.323v4 provides this feature (a way to bypass the UDP packet size
limitation) for this same reason.


Does it make sense to have this?, If no, then why not?

 SupportedProtocols ::= CHOICE
{
        nonStandardData                 NonStandardParameter,
        h310                            H310Caps,
        h320                            H320Caps,
        h321                            H321Caps,
        h322                            H322Caps,
        h323                            H323Caps,
        h324                            H324Caps,
        voice
        .......,
                SIP                             SIPCaps
}


regards,


charles

Charles,

Wrong in my opinion, but I would hope other experts would express their
opinions too!  The problem is I'm not sure whether this is a question of
understanding or of detailed definition of the phrase "third party" in this
context.
My understanding of the phrase "third party registration" would be one H.323
entity registering at a gatekeeper on behalf of other H.323 entities.  My
understanding of the word "registration" of this context is that it can only
apply to H.323 entities.  In this context the IWF can be considered to be at
the extreme edge of the H.323 network, so any "registration" it does is on
its
own behalf.
Maybe what you actually want is some equivalent to the supportedPrefixes
that
arrived in version 2, for SIP gateways.
Whatever we agree you want, though, I think it is worth trying to reach some
consensus among experts in this group as to what the phrase "third party"
means
in this context - as your understanding and mine are clearly in
disagreement.

Regards,
Chris
