Just for the sake of discussion, this will be part of what I'll be working on
over the next several weeks.  The number of available audio codecs will be
increased to at least 32.  And, to head this off at the pass, unless somebody
outside of Digium wants to contribute an advanced media negotiation framework,
it's unlikely that any other work will get done in this area in the immediate
future.  However, given that we're currently full up on audio codecs, this is
one item that needs to get done, even in the absence of that more advanced
media framework.
