For Fone API Clients - Starting a phone call allows the browser to create a request to FONE API  telling you how to route the call to other browsers, devices, or other carrier networks.

The call logic is based on a number of foneAPIML verbs such as to voice out to the caller and to take dialpad input from the user. The browser connects to FONE API via WebRTC then out to the carrier network.
