Hi Suhas,

I will add an explicit definition of "shared address" to the next version of the draft.

Regards,

Christer

Hi Christer

Looks good to me. Except, I am assuming "shared address" is defined in the spec somewhere. I might have missed it as well.

Cheers
Suhas

Hi,

In Vancouver we decided that an Offerer MUST NOT assign a shared address (with a non-zero port) to multiple m- lines until the Answerer, within the session, has indicated support of BUNDLE.

I suggest the following piece of text to implement  the decision in the BUNDLE spec:

        "The Offerer MUST NOT assign a shared address with a non-zero port
        value to multiple "m=" lines until it has, within the given session,
        received an SDP Answer indicating that the Answerer supports the
        BUNDLE mechanism."

Note that there will be specific text regarding the usage of port zero for 'bundle-only' m- lines.

Regards,

Christer
