asterisk users - Aug 2013 - Dedicated hangup extension h

Hello,

We have a Kamailio SIP Proxy in front of our Asterisk cluster for incoming calls
from our carrier.

The sip.conf looks like this:

[kamailio1]
type=friend
host=10.0.0.1
context=incoming
disallow=all
allow=alaw

All calls hit the incoming extension. In the extensions.conf we have multiple
extensions configured, but now I have to add one which uses the special h
extension to perform a CURL action whenever the user hangs up. The problem is
that once I've registered a h extension, it is executed for all extensions
in the incoming context.

exten => _X.,1,Playback(invalid)
exten => _X.,n,Hangup

exten => 1000,1,Playback(welcome)
exten => 1000,n,Read(dtmfinput,,,,,15)
exten => 1000,n,Hangup

exten =>
h,1,Set(response=${CURL(http://sample.company.local/PostHandler.ashx,var1=${dtmfinput}&var2=1000)}<http://sample.company.local/PostHandler.ashx,var1=$%7bdtmfinput%7d&var2=1000)%7d>)

Is it possible to give each extension its own h extension? If not, is there
another way to do this?

Hi Grant!

I do not know of a way to have multiple 'h' extensions in the same
context.


But you can easily make an appropriate context for your custom need!


exten => _X.,1,Playback(invalid)
exten => _X.,n,Hangup

exten => 1000,1,Noop(Go to CURL Hangup)
exten => 1000,n,Goto(CURL_Hangup,${EXTEN},1)

; ..... your context goes on ....


; Added Custom Context

[CURL_Hangup]

exten => _X.,1,Playback(welcome)
exten =>_X.,n,Read(dtmfinput,,,,,15)
exten =>_X.,n,Hangup

exten =>
h,1,Set(response=${CURL(http://sample.company.local/PostHandler.ashx,var1=${dtmfinput}&var2=1000)})

I would set a "no-use" flag in all extensions that you do not want to
use
the h, and then test for it in the h extension itself - if it is set you
could just run the Hangup application.

The magic you're looking for exists in Asterisk 11:
https://wiki.asterisk.org/wiki/display/AST/Hangup+Handlers

Basically, instead of h extensions, that fire based on what context the call
ended in (and fire for all extensions in that context), you attach a handler to
the call at some point (such as, when it enters a specific extension).  At the
end of the call, each hangup handler fires as a Gosub, in reverse order of how
they were added (the last one added fires first).  Life gets a little
entertaining if you're trying to remove hangup handlers and don't
remember what order they went on in (your removal choices are either the last
one added or all of them), but for what you're describing as what you need,
hangup handlers should work fairly well.

Thank you,
