Hi:

Section 3.1 of draft-rosenberg-sip-conferencing-models-01.txt mentions that for Large Scale Multicast conferences UAs do not need to send BYE when they leave the conference. 

I believe this mechanism wil work in most of the scenarios. However, what about when there is a proxy that Recorded Route, usuallly because it wants to be informed when the session is over. The rr proxy will never get a BYE, and it will have to rely on other mechanisms (let's say, session-timer) to remove the installed states.

I think the proposed behaviour of forgetting about BYEs will break in the common assumptions that BYEs are sent to indicate the end of the signalling relatioship.
