Summary:                    [patch] SIP Protocol Violation when REFER rejected
in sip_transfer (Cisco CCM, post answer), and Transfer application misclaims 
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!
