Basic Call Features

code to the server when a certain action takes place. For example, if you set the Always
Forward on code to be *71 (may vary on different servers), and the target number to be
1234. When you activate Always Forward on the IP phone, the IP phone sends *711234 to
the server, and then the server will activate Always Forward feature on the server side,
hence being able to get the right status of the extension.
