Hi, I don't think it's within the scope of the draft to say what the UA should do - unless it is specified somewhere else, in which case the draft could refer to that specification.

I noticed this in section 3.1: o To avoid receiving media from undesired sources, some User Agents assume symmetric RTP will be used, ignore all incoming media packets until an address/port has been received from the other end, and then use that address/port to filter incoming media packets. Should a UA silently drop/ignore the packets or is it OK to send ICMP port unreachables? If the UA does not follow RFC3261 ("start accepting RTP once it sends the SDP offer") the remote endpoint would have to be able to deal with ICMP errors.
