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


The phone is a OpenStage20 (V1 R4). The 404 response might be the result of a bug in the firmware of the phone, but asterisk should destroy the channel after some time.

If the phone is unplugged the channel will disappear.

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.

Tanks a lot,

now all sip channels come to an end.

If the patch on ASTERISK-12201 fixes the issue, then I will close this as well. Please feel free to re-open if the other patch did not completely fix the issue.
