Hi,
I am having some trouble with parked calls timing out.
In features.conf:
[general]
parkext => 800 ; What extension to dial to park
parkpos => 801-820 ; What extensions to park calls on
context=parkedcalls
parkingtime=120
After the Park timesout it calls the phone that the call was parked
from. If the phone is BUSY the call just get dropped. (Call waiting is
off for other reason)
What I would like is control over the call if it does not get answered
from the redial.
I have added a [park-dial] context in extentions.conf
I am not sure how to gain control over the call however. After the call
back to the phone that parked it, it reaches the hangup extension.
I can take control of it with the _. match however I don't think that is
the correct way. Is it?
Also if I do take control this way. Asterisk crashes in some cases. It
crashes when the channel has a <ZOMBIE> at the end of it.
I am not sure what this is. I take it that the parked person got sick of
waiting and hung up????
[park-dial]
; The parked call rings the person that parked the call first! Then
comes here
;exten => _.,1,NoOp(Park Timeout - ${CALLERID(num)})
;exten => _.,n,Set(CALLERID(name)=Park Timeout)
;exten => _.,n,SIPAddHeader(Alert-Info: Classic-2)
;exten => _.,n,Dial(SIP/500,30)
;exten => _.,n,Dial(SIP/518,30)
;exten => _.,n,Dial(SIP/504,30)
;exten => _.,n,Queue(queue-reception)
exten => _SIP/5XX,101,NoOp(101)
exten => _SIP/5XX,201,NoOp(201)
exten => _SIP/5XX,n,Dial(SIP/550,30))
exten => t,1,NoOp(Park Timeout - ${CALLERID(num)})
exten => h,1,NoOp(Park Hangup - ${CALLERID(num)})
exten => h,n,Hangup
Here is a CLI dump of what happens with the above.

***CRASH***
Can someone point me in the right direction?
How should parked calls be implemented if this is wrong?
