RE: [XCON] CPCP Requirement: de-activating a conference

["Drage, Keith (Keith)" <drage@lucent.com>]

May I was not so clear in my original mail.

I do not propose we define a reservation protocol.

However something like the framework document should clearly identify that things like reservation protocols may exist (if indeed they do), and define its scope.

In considering requirements for CPCP we can then evaluate whether they are in scope for CPCP or in scope for the reservation protocol, rather than seemingly a more ad-hoc judgement of whether it is nice to put it in CPCP.

regards

Keith
