Hi,

>> IF we agree that the PT binding is per session, and not per direction, we can update that part of 3264, because THAT’s what causing Martin’s issue.
>>
>> RFC 3264 might be slightly ambiguous about the answer since it does not even define the "session", but it never states that binding is per direction. It states
>> that binding MUST NOT change for the duration of a session with no direction mentioned in this restriction. This mean we might need a clarification but not necessarily an update.

Well, technically it is an update to RFC 3264, even if the new text only clarifies existing text :)

>Bigger problem is that this requirement is unimplementable with 3pcc and routinely ignored. This is definitely a problem and needs an update to resolve.

But then, is it a good idea to say that the PT binding is for the whole O/A session? What preventing us from saying that it is per direction? The fact that it would conflict with the RTP session definition?

Regards,

Christer
