Hello, I am wondering what to do with an SDP in a 200 to an UPDATE without SDP in an established dialog, for example as a response to a session refresh triggered by SST. There is two cases: - the SDP has not changed (to what is established) - the SDP has changed
I can't find any text neither in RFC 3311 nor in 3264 which would explicitely prohibit placing an SDP in such a 200 reply. In RFC 6337 Table 1, though, the only pattern of offer/answer involving UPDATE is the one with offer in the UPDATE, and answer in the 2xx. Or is such an SDP considered a "Session Description That Is Not an Offer or an Answer" (2.4 in 6337) and thus should just be considered informational? What if the SDP is different to the established session? Thanks for any hints!
