Re: [XCON] CPCP Requirement: Repeat times

[Paul Kyzivat <pkyzivat@cisco.com>]

Roni,

To me this is splitting hairs. I think it makes sense to include start 
and stop time(s) in the conference policy - they are quite consistent 
with other kinds of policy information. How that policy gets acted upon 
is irrelevant, as long as it does get acted upon - it is an 
implementation detail. It might be acted upon directly by the policy 
server, or by a separate conference server, or some other way. The 
simple fact is that you can influence it by changing the policy using CPCP.

Do you really want to standardize another active entity and another 
protocol just for this?
