Manager API, call not answered but enter dialplan anyway?

Asterisk Asterisk Support
1

I’m originating a call from the Asterisk Manager, and using DeadAGI when the call is hung up to update a database with the results of the call.

The result is ‘noack’ if the callee hung up, ‘ack’ if they pressed a number when propted, and ‘timeout’ if they forget to press anything.

This works.

However, I want a fourth result: ‘noans’ for when the call isn’t answered at all.

From what I can see, the dialplan isn’t even started if the phone isn’t answered, so of course it isn’t hungup, and my DeadAGI script isn’t called.

I’d rather not have to deal with this case in the Manager, as I then have database calls and code in seperate places.

Is there a simple solution to this I’ve missed? Or even a more complex answer?

can you use ${DIALSTATUS} handling in the context you start the call in ?

I should post my config.

Manager Actions:

[code]

Context: test
Extension: s

Extensions.conf

[code]
[test]
exten => s,1,SetGlobalVar(STATUS=noack)
exten => s,2,Background(gaAck)
exten => s,3,WaitExten(10)

; press 2 to repeat
exten => 2,1,GoTo(s,1)

; press 3 to acknowledge
exten => 3,1,SetGlobalVar(STATUS=ack)
exten => 3,2,Playback(gaThanks)
exten => 3,3,Hangup

exten => t,1,SetGlobalVar(STATUS=timeout)
exten => t,2,Hangup

exten => i,1,Playback(invalid) ; "That’s not valid, try again"
exten => i,2,GoTo(s,1)

exten => h,1,DeadAGI,ack.php[/code]

baconbuttie: I don’t think the call even enters the context if the phone isn’t answered. If I’m wrong, can you elaborate?

I think I have half a solution.

Using the manager API I originate a call to an extension. That extension is then responsible for calling the desired number.

The problem is now inverted. If the call isn’t answered, all is fine; I get the expected ‘NOANSWER’ in the database.

If the call is answered, I get two entries. What’s happening seems to be that two calls are getting placed, and Asterisk is trying to bridge between them. When each call gets hung up, they both trigger the DeadAGI script.

What’s causing this, and how do I stop it?

(192.168.0.20 is the ip of the machine that’s both originating and recieving the call. The Asterisx box is on 192.168.0.10)

can you add some filtering in your AGI so that it ignores the Local channel leg of the call ?

6

So it isn’t an error that it places the two calls?

I can easily add the filtering if that’s the best way to fix it.
