Sorry for going OT, but this is a good example of why I dislike SIP; to
me it seems like someone sticky-taped a bunch of not quite ideally
suited standards together (HTTP? Really? Over UDP??), much of which is
then ignored by people who 'just need to get calls working'. The result
is that you might not be able to rely on something as fundamental as
media attributes being parsed in an SDP.
