Hi, I do have some other more detail comments on the draft: 1. The address format in the draft. Currently it is restricted to IP. Is this something the WG is fine with? RTP is very lower layer transport agnostic. Thus it would be good to at least have a address type field that can go beyond IP. Also the data entry would be good to be more flexible. 2. I also find a few places where the MIB description text makes references to "calls". I don't find that appropriate. In most cases it should discuss sessions I think. 3. What is the definition for active sessions? 4. rtpSessionSessionIdentifier: I don't see how a SSRC can be a unique identifier for a session. However this do tie in with the other mail and the general question of how to identify sessions. 5. rtpSessionMaxNumEntries: What type of entries is it providing a limit to? 6. I also question the deletion of the sender and receiver entries when they timeout. Isn't this information that one maybe want to retrieve after that a particular session participant has left the session. 7. rtpRcvrPT: I don't see how the payload type belong in the receiverEntry. It is not included in the RTCP RR, thus not know that way by the writer of the record.
