Summary:                    SIP Protocol Violation when REFER rejected in
sip_transfer (Cisco CCM, post answer), and Transfer application misclaims
success.
Description: 
A call from Cisco CCM was answered and then transferred back to a different
extension on the Cisco.

Asterisk first reported a successful TRANSFERSTATUS, then tried to use a
REFER method.  This was rejected as unsupported.  Asterisk responded with
BYE, which the Cisco accepted.  However it continued to try to send REFERs,
which the Cisco, of course, rejected, because the session reference had
been deleted by the BYE!

Add better support for relaying success or failure of the ast_transfer()
API call.

This API call now waits for a special frame from the underlying channel
driver to
indicate success or failure. This allows the return value to truly convey
whether
the transfer worked or not. In the case of the Transfer() dialplan
application this
means the value of the TRANSFERSTATUS dialplan variable is actually true.
