I have not once in my life seen someone use a hostname instead of an ip in an sdp, and I do not believe it is legal.

Using hostnames in the record-route and SDP addresses meets the requirement since the OS will synthesize an IPv6 address when a DNS query is performed, but according to the documentation they strongly urge applications to avoid using address literals in their applications.
