Summary:                    [patch] Unhold fails if first SDP on OK,
particularly Cisco CCM 6
Description: 
Cisco CCM 6 appears never to send SDP on the INVITE, so Asterisk
effectively makes the offer, even when the Cisco is re-inviting because a
CCM hosted phone has gone on hold.  Asterisk sets up its SDP from flags[1]
in the channel private data structure, which means that, if the channel was
on hold, it will offer a=inactive (observed, although a=recvonly also seems
possible).  Even if the CCM intended to unhold, the only possible response
to an a=inactive offer, is a=inactive.  Asterisk should only actually use
saved state if it is making the response.  For an offer, as it looks like
it can never locally hold, it should offer a=sendrecv.

It would probably be worth changing the subject, as this issue forked and
the resulting commits were for a secondary problem.  I'd suggest something
like "Transfers application reports success even when transfer fails or is
rejected".  That covers what the commits actually covered.
