Extensions

An extension is an endpoint for a call and can have multiple registered devices in which to send that call. Calls can be sent to an extension by a direct dial number, a call transfer, a group or queue, or a flow and are handled as follows:

Ring (all registered devices) → Find Me (ring mobile number) → VoicemailHangup (or return) Hint — Phones will work the same from any internet connection, they don't have to be at the same physical location.
