Hi,

>Can you or anyone else provide the reference to the document which prohibits using the same port in multiple m= lines?

It is not prohibited, but the SDP spec says that the semantics is undefined.

Now, in BUNDLE we can define semantics for usage of multiple m= lines, and BUNDLE endpoints would support that semantics.

The problem is if you send an initial INVITE that reaches a non-BUNDLE endpoint. There is no way to know how that endpoint will process the offer, and we have seen that the offer gets rejected (in different ways).

Regards,

Christer
