[Asterisk-Users] IAX2->SIP->meetme = ZOMBIE

[Ryan Courtnage]

Hi all,

I'm experiencing a problem with SIP channels going ZOmBIE after the
following sequence of events:

- IAX2 client calls SIP client
- SIP client consultive transfers (using sip REFER) the call to a MeetMe
extension, and hangs up.

At this point, the IAX2 client will indeed be in the meetme room, but a
'show channels' at the * CLI reveals that the SIP channels that were
involved in the consultive transfer are still bridged and one is ZOMBIE.
This will persist until issuing a 'soft hangup' to them.

Oddly, I can only duplicate this problem when it's an IAX2 call being
transfered (by a SIP client) to a meetme room.  The phone's method of
transfer (REFER) also seems to be a variable, as server side (#)
transfers don't exhibit the problem.  

I've tested with both the Sayson 480i and the Uniden uip200.  
I'm using Asterisk v1.0.2 (CVS-v1-0-11/01/04)

What could possibly be causing this, and can anyone reproduce it?

Thanks
Ryan
