[Asterisk-Dev] ParkAndAnnounce() - trying to add var to indicate parked exten

[Steve Blair]

I may have missed the point but this description sounds so much like what I
encountered I had to reply.

I use Asterisk for voicemail only. SER does the call routing and 
registration.
I wanted to add call park to the Asterisk machine but once the called
IP phone blind transfered the call to the parking lot number there was 
no way
for the annouce piece of ParkAndAnnouce to call back.

Well it turns out there is. In my case I needed the Referred-By user. I 
got it
this way:


;
; Call Park
exten => _700,1,Answer
exten => _700,2,Wait(1)
exten => _700,3,SIPGetHeader(REFBY=Referred-By)
exten => 
_700,6,ParkAndAnnounce(parkedcall16:PARKED|7200|SIP/${REFBY:5:5}@12.1.6.3:5060|default|${EXTEN}|3)


Hope this helps,
_Steve
