[asterisk-dev] Adding new ARI for application execute

[Kevin Harwell]

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?
