Hi,

Based on the discussions, we basically have two alternatives:

Alternative 1: Forbid the usage of the same PT value within multiple m- lines.

Alternative 2: Allow usage of the same PT value within multiple m- lines, and if the answer does not support whatever extensions that are needed for the offerer to distinguish the media, the offer needs to handle that, e.g. by sending a new offer with unique PT values.

IF we choose Alternative 2, we still need to decide whether we let the offerer decide when it's "appropriate" when to use the same PT value, or whether we need to specify some rules (as suggested by Colin). My personal proposal is still to let the offerer decide, and not specify any rules.

Regards,

Christer
