Making a call is not a problem, you can use platformRequest method for that (look into the API Docs for more info). Disconnecting the call from your program could be a problem, since the call itself is not managed by the AMS anymore, so you don't have access to it after your platformRequest method.

I don't know if that is possible, because the application may have to be closed if the system does not have enough capabilities and resources, so it depends on the phone. Read the API docs for the platformRequest method for more info about this.
I would give it a try though and see what happens.
