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!

The transfer application in the dialplan is totally broken. There's no way
for the SIP channel to come back and say "I failed". This needs to be
seriously redesigned.
