Summary:                    Channel re-invited on destination ringing not
re-invited back if ringing abandoned.
Description: 
An incoming SIP call is answered by an agent and then AMI transferred to a
PSTN line on Cisco CCM.  The Cisco provides SDP on the Ringing response and
Asterisk re-invites the incoming call immediately it gets that response.

The Dial command times out and cancels the outgoing call, but at no time
does the re-invite get undone, even when the dialplan eventually
successfully returns the call to the agent.  The result is a silent call.

The un-re-invite can be forced by parking the call and then unparking it
(in this case with an AMI Originate which queues it back to an agent).

This is a big problem for us as it is important for our application that
as many calls as possible have their speech path removed from the Asterisk
system.

I am also concerned that specifying multiple destinations in the Dial
command, may not inhibit the re-invite, leading to conflicting re-invites,
in the order of the Ringing events.  However, I haven't confirmed that this
is the case.

After further examination of the log files I believe my directrtpsetup
change fixed this. While this option may have been disabled it was still
being done on part of the leg, causing things to go weird. The change I
made now ensures directrtpsetup is indeed disabled if configured as such.
