Even TDM trunks require media descriptors, if for no other reason than to
indicate Mode and medium.  Annex C shows a pile of other properties which
may be specified.  I view Annex C as an agenda for us to augment SDP to
match, as we have discussed in other threads.

In any event, TDM to TDM operation is nothing special in Megaco/H.248 -- you
just place two TDM terminations in the same context.
