John,

I agree that it is not mandatory to consider recorded stream of a
specific participant in several CS within the same CSG as one recorded
stream but SIPREC protocol design MUST NOT restrict a SRC in case it
wishes to design in such a way.

Thanks
Partha

We seem to have consensus that a Media Stream object represents a
recorded media stream, contributed to by one, several or all
Participants. However, Partha also wrote:

"2) Each MS lifetime related to CSG because participant may move from
one CS to another CS within single CSG and also CSG will span across
multiple RS."

I am not sure we had resolved this during earlier discussions on the
scope of an MS object. Although the same Participant can participate in
several CSs within the same CSG, I don't think the recorded media
streams need to be considered the same. Any other views?

John (as individual)
