[asterisk-app-dev] Handling Inbound Calls with ARI

Thank you very much for your quick reply.

Since the channel is then always in Stasis they can do what they need to connect it to the right place. It also makes it easier to implement different strategies and business logic.

I have read about this solutions before and I am very interested in it. Just to ensure I understand this properly.

If I want to write my own Queue application, I would do as follows:

1. I send all incoming calls to stasis by using Stasis(appname) in my dialplan

2. I have a websocket connection always listening for event and connected to this application, since the "Stasis()" command fails if the application is not registered on asterisk.

3. I would write my own business logic to handle incoming calls and manipulate them however i want.

I assume that I can move a channel from one stasis application to another, is that correct?

Thank you very much.

No, the channel has to be in Stasis to control it. The ability to move a channel into Stasis arbitrarily is on the feature wish-list[1].

Generally instead of doing that people have been replacing the Queue application with their own ARI application instead. Since the channel is then always in Stasis they can do what they need to connect it to the right place. It also makes it easier to implement different strategies and business logic.
