Hi,

One of the open issues we have in BUNDLE, is when it is allowed to use the same PT value within multiple m- lines.

We tried to come up with different criteria, including a "codec configuration" concept, but we never managed to agree on something.

So, in London, I intend to suggest that we simply say: if you offer the same PT value within multiple m- line, make sure you can handle the associated media when it arrives - period (keep in mind that you always indicate what you want to RECEIVE - the remote peer can still ask you to SEND using different PT values).

If you don't like this, please provide an alternative solution, because I want to close this issue in London. There is no idea to keep "taking the issue back to the list". We've done that for a few meetings already.

Regards,

Christer
