Hi:

Some time ago Marc reported an editorial errata in RFC 5245. The errata 
was that the ice-mismatch SDP attribute was listed as session-level only, 
but it should have been listed as media-level only.

IANA has fixed the SDP parameter registry,
http://www.iana.org/assignments/sdp-parameters/sdp-parameters.xml
and now the ice-mismatch attribute is listed as media-level only, and 
there is a pointer to the errata text.
