Outbound call dialplan syntax

I’ve written a few dialplans for outbound calls. I’m unfamiliar with the ‘flow’ of a dialplan because of things like pattern matching and ‘extensions’ which don’t lend themselves to the traditional imperative style of programming that I’m used to.

Here is a dialplan that currently has a problem:

exten => _X.,1,AGI(foobarCallback.php|UpdateCallStatus|${CALLID}|7)
exten => _X.,n,AGI(foobarCallback.php|EnsureFile|${PRODUCTID}|${PRODUCTIDN})
exten => _X.,n,Answer
exten => _X.,n,GotoIf(${RECORD}="1"?rec:start)
exten => _X.,n(rec),Monitor(wav|/var/www/html/uber_sys/${CALLIDN}|m)
exten => _X.,n(start),Wait(1)
exten => _X.,n,AGI(foobarCallback.php|UpdateCallStatus|${CALLID}|11)
exten => _X.,n,Playback(custom/${PRODUCTIDN})
exten => _X.,n,Hangup
exten => h,1,GotoIf(${RECORD}="1"?rec2:end)
exten => h,n(rec2),DeadAGI(foobarCallback.php|UploadCallRecording|${CALLID}|${CALLIDN})
exten => h,n(end),DeadAGI(foobarCallback.php|UpdateCallStatus|${CALLID}|29)
exten => h,n,DeadAGI(fixdollarsign.agi)
exten => h,n,System(/var/lib/asterisk/agi-bin/UploadCallRecording.sh "${CALLID}" "${CALLIDN}" &)
exten => h,n(callstatus),System(/var/lib/asterisk/agi-bin/UpdateCallStatus.sh "${CALLID}" "${DIALSTATUS}" &)
exten => h,n(done),NoOp("Exiting here!")

It currently ‘works’ but has a problem where if the call is unsuccessful (i.e. a call is made to a wrong number) then none of the dialplan is executed, at least as far as I can tell, because our initial call to foobarCallback.php|UpdateCallStatus is never executed.

I did some reading and read about the ‘s’ extension which is used when starting a call, so is this the change I need to make (to the first line)?

exten => s,1,AGI(foobarCallback.php|UpdateCallStatus|${CALLID}|7)

To be honest, I wrote the dialplan by copying and pasting from others already-present on the server and I wasn’t sure of what I was doing, so I’m sure there’s plenty of cargo-cult code in there, such as the ‘_X., n’ stuff, and I’m not sure if I’m using ‘h,n’ correctly either.

Can someone take a look at the dialplan and let me know if my fix is appropriate, and also if it’s sensible to replace the strange ‘_X.,n’ stuff with something more understandable?

Thank you

Take a look on www.asteriskdocs.org in order to understand the basics.

Expressions must be wrapped in $[…]

There is not Dial application call, so how can it be making an outgoing call? It could be in the AGI, but we have no idea what that is doing. As you say even step 1 isn’t run, I suspect this is actually being run from call files. If you want to handle errors on the A leg of these, you have to use local channels.

However, automated outgoing calls are a sensitive topic, so you need to convince people that you aren’t generating phone spam.
