asterisk users - Apr 2019 - [asterisk-app-dev] ARI application execution feature survey

Hi Asterisk users,

I'm one of Asterisk ARI users, and trying to designing the new ARI for 
application execution in Stasis().

This will be made possible for executing the applications in the 
Stasis() application.

But, before going further, I would like to know which application needs 
to be considered.

Because this feature will introduce new Stasis behavior, I would like to 
test the applications as many as possible before submitting the code.
However, I can't test all of them, so I would like to make a priority 
and list.

If you want to use your favorite application with this feature, please 
reply this.
I will add to the list. :)

Btw, I'm considering the app_amd, app_queue for myself. :)

For more detail of this feature, you can see it here.

Thank you.

Kind regards,
Sungtae

Can you explain why app_queue would be executed from ARI? What value does ARI
bring in that regard?

Um... Because... I can?
Tbh, no reason... app_queue is just my favorite module. :P

Yes, there are certain applications which are logically building blocks to
bigger applications. AMD is one of those which would be best if it were its own
functionality within ARI, but allowing execution of the application is a good
enough option. I don't think applications such as Queue, Dial, ConfBridge,
Playback, Record or some others really make sense.

Assuming the TALK_DETECTION function isn't sufficient, it's worth noting
that the information that AMD uses to make its decisions are available to
the parts of Asterisk that make up ARI. I wonder if it would be better to
simply wrap up the existing talk detection events under some other HTTP
resource  rather than open up this entire concept.

While I'm pretty far removed from the guts of Asterisk these days, the
notion of having dialplan applications be executed from within ARI just
fills me with some fear. You can certainly open up some nightmare scenarios
where people invoke Stasis from within Stasis recursively, or invoke GoTo
or other dialplan context affecting applications.

For that matter, many of the monolithic dialplan applications have specific
options that place channels into dialplan contexts that execute after their
execution. I'm not even sure I can begin to wrap my head around what that
will do to a channel in ARI.
