And we can also respond with 200OK as mentioned in rfc3261 with no change in our sdp. "If the user is already a member of the session, and the session parameters contained in the session description have not changed, the UAS MAY silently accept the INVITE (that is, send a 2xx response without prompting the user)."

Can anybody help me find relevant RFC/other info on how UAS should handle re-INVITE that is intended as a session refresh and not for modifying the session ?
