RE: [XCON] CPCP Requirement: Conference package subscribers

["Rosen, Brian" <Brian.Rosen@marconi.com>]

I didn't read Jari's answer the same way.

I think you could easily have a PC app that was not a "participant",
in that it never sends or receives media, but does:
	Read and Modify Conference Policy
	Read and Modify Media Policy
	Read and Modify whatever floor control mechanism there is

This would be a PC app for a "dumb" phone.  The phone is the "participant".
It would have a dialog with the focus, and send/receive media.  It
would be conference un-aware.

So, the PC app has to be able to subscribe to the conference package,
but is neither a dial in, nor a dial out participant.
