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

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

I do not remember seeing the existence of this separate protocol in any of the conferencing documents so far (either in SIPPING or XCON). (If I am wrong then pointers gratefully received). If it exists, then I think we should clearly identify what its scope is, if only to aid the discussion of what the other protocols may or may not do.

We clearly need a start and stop time for conferencing. At the moment the only protocol it can be in is the CPCP. If we are going to have an informed discussion about why it is not in CPCP we need to understand clearly what the alternative protocol is.

regards

Keith
