"image" does not seem to be defined as a valid <media> value. (RFC 4566 section 5.14; there seems to be no IANA registry for <media>, so it appears that no additional <media> values beyond RFC 4566 are valid.) "NULL" is not a valid <proto> value for c=IP4. (See http://www.iana.org/assignments/sdp-parameters.) For extensibility, it would be best if the device ignored m-lines whose <media> it does not understand, but that might require the device to produce a correct "m-line inactive" response for a <media> type that it does not understand, which would not be possible.
