[asterisk-users] Problem with parking

Hi,
I'm having problem with call parking.
When I park call, either via transfer to xten or park digit sequence from
features.conf, I hear the parking lot number read to me and the user gets
transferred.
However, MOH stops for the caller the moment user is transferred.
The user can be retrieved by dialing the parked extension and voice resumes.
If the parked user hangs up, the channel state does not update (nor the
hint) and call seems to be live still.
If the timeout for the park is reached, the user is not transferred back
(nothing happens actually -- he is just able to stay parked forever).
Even after the user hangs up, the parking lot extension exists and is
callable, but when that is done (the parking extension is called), it
answers and promptly hangs up and then is available for parking again.
Yesterday I had everything working like a charm, and I don't think I have
changed anything, although that seems increasingly unlikely since things
don't usually break on their own. I've restarted asterisk numerous times and
tried changing things I think are relevant, but with no avail.
It does not matter whether the caller is coming in from a SIP trunk or a SIP
peer.
The SIP messages look normal. When the caller hangs up while parked he sends
a BYE to the asterisk to the callee's number, and the asterisk replies with
ACK.
Any help would be appreciated.

==== Call sequence ====
2556 calls 2552. [a calls b]
2552 answers call [b answers]
2552 presses # (blind xfer) [b starts transfer]
2556 hears MOH [a hears MOH]
2552 presses 10 (to transfer to parking lot) [b enters 10]
2556 stops hearing MOH [a stops hearing MOH]
2552 hears asterisk read 11 aloud (parking lot number) and subsequently
hangs up [a hears parking lot number and hangs up]
2556 is in parking lot, total silence on phone [b is in lot with no MOH, or
a hissing noise if he was transferred at a certain time in MOH]
2556 hangs up [b hangs up]
2552 calls 11 (which is parking lot slot) [a calls 11]
11 answers and hangs up

11 at parkedcallsstill shows InUse.

##### It is also worth noting that even if call reaches 45 seconds in length
after transfer, it does not transfer back to 2552. It just stays in the
parking lot indefinitely.
