Summary:                    SIP channel never gets destroyed - Tx: BYE -
response 404
Description: 
Two calls are made from one SIP Phone and SIP REFER is used to connect the
callees. Works fine so far.

The problem is, that asterisk fails to destroy one of the sip channels.
The history shows theese 4 lines again and again:

37. AutoDestroy     38070dc46ab0085d
38. TxReqRel        BYE / 104 BYE - -UNKNOWN-
39. SchedDestroy    32000 ms
40. Rx              SIP/2.0 / 104 BYE / 404 Not Found

Did the phone already clear the call after the REFER succeeded ?
I had a (possibly) similar problem with blind transfers ; it is described
in issue 12865 <http://bugs.digium.com/view.php?id=12865> and I proposed a
patch that is in trunk but not yet in 1.4(.21.2). Maybe you can give it a
try.
