Hi Kevin,

Thank you for replying.

Yes, I agree with how the ARI was designed. Btw, because of that, I can see some improvement point.

While the channel is out from the Stasis to executing the other application as you said(Yes, I'm doing that now), the ARI losing the control of the channel. Which is not possible to doing anything(including hangup).

Because of this, I wanted to add this feature.

And.. yes, it's possible. I've already submitted some draft code for that(not finished it yet), but you can see how this is working at here.
With some simple test, it was working what I expected.

And you can see some detail test results here

Thank you.

Kind regards,
Sungtae

Just throwing an idea out there (I have no idea if this is possible or how feasible it would be to do this).

ARI is built to interface with applications. A given application controls, and manipulates channels, bridges, etc... within its context. There are already mechanism in place that allow a channel to exit an application, and hand control off to something else. For instance, using 'continue' a channel is passed to the dialplan, and 'move' a channel is passed to another application.

With this in mind would it make sense to have the relevant dialplan applications register themselves as an ARI application? Then you could simply reuse existing definitions (e.g. move) to "transfer" channel ownership to another application. From an ARI perspective it doesn't care where or how an "app" is implemented it just has to conform to the interface.

Obviously, this would mean modifying each chosen dialplan application in some way so that it could register as an ARI application. It then uses the same call to 'move' or 'continue' when it is done with a channel.

Again I have no idea if this is possible given the current state of things, or if would simply be adding a few new API calls that make it easy for a dialplan app to become an ARI application. But it might be worth some time to look into?

    Hi Asterisk team,

    I want to talk about some feature for the ARI.

    Currently, ARI doesn't allow executing the Asterisk application.

    But this makes ARI users giving up and tired to use the ARI.
    Because to use the Application, it has to be exit from the Stasis and
    jump to the dialplan to executing the application. And have to
    execute
    the Stasis() again to back to Stasis.

    Since it makes the channel needs to be exit from the Stasis, ARI
    can not
    control the call while it's not in the Stasis. This makes also
    hard to
    control the call.

    So, I was thinking how about make the stasis/ARI possible to
    execute the
    applications? And I've created ticket for adding this feature to ARI
    which is enabling the ARI to executing the application.
    https://issues.asterisk.org/jira/browse/ASTERISK-28365

    Btw, In terms of 'Application' things in Asterisk, I know it's bit
    weird
    sound.

    Because it's executing the application in the application. If the
    Application executed in the Asterisk, all the dialplan's info was
    changed, but this feature will not change it.

    It wasn't done in the Asterisk before. But if we think of the
    Stasis()
    application's specialty, I think this would be OK to having this
    feature.

    I've committed some codes regarding this, but put it into WIP status.
    Because I want to get more discussion about this before going further.

    Thank you.

    Best regards,
    Sungtae
