Outbound Endpoint - no ARI events

Asterisk Asterisk APIs
1

I have an ARI client application and originate calls through an external provider. I defined an endpoint in pjsip.conf and an extension in the dialplan for that.

The call is initiated and the phone rings but I don’t receive any ARI Events in my event handler …

Worked in my local testing environment when I called a soft phone directly.

I guess it has something to do with the created bridges?

exten => My-Outbound,1,Verbose(2,Outbound call by caller ${CALLERID(name)} to callee ${CALLEE})
same => n,Verbose(EXTEN = ${EXTEN})
same => n,Dial(PJSIP/${CALLEE}@My-Outbound)

Note that with ARI, you have to specify which Stasis “applications”† are associated with the events you are listening for. You specify this with the Stasis() application‡ in the dialplan.

Alternatively, your ARI event listener can specify the “subscribe-all” option, to listen for all events.

†Bad choice of term, don’t you think so, considering that those commands you use in dialplans are also called “applications”.
‡See what I mean.

I can see Asterisk is sending ARI events to my app, but they never arrive …

Was an application internal problem … a databinding dependency.
