Re: [XCON] Centralized Conferencing Manipulation Protocol

["Mary Barnes" <mary.barnes at nortel.com>]

A client that has not implemented CCMP (i.e., a SIP client that supports the SIP Conferencing Framework (RFC 4353) and SIP conferencing UA functionality (RFC 4579) ) can still participate in a conference that is based on the XCON FW and that also supports clients that have implemented CCMP.   This is discussed in section 10 of the XCON FW (RFC 5239):

 

   "User agents that only support [RFC4579] and do not
   support the Conferencing Control Protocol are still provided basic
   SIP conferencing, but cannot take advantage of any of the advanced
   features."

Subject: [XCON] Centralized Conferencing Manipulation Protocol

My question refers specifically to the implementation part of CCMP.  I was wondering if all firmware on user agents would have to be updated before this protocol can be used or is this still compatible with the current version of SIP.  Also, what is new about this protocol?  I thought current conferencing already had the ability to modify the enviroment?
