## Description

This is the interface to a call. It has a id, name and a state. Only the state changes after creation. If the state is CALLS_CALL_STATE_INCOMING, the call can be answered with calls_call_answer. The call can also be hung up at any time with calls_call_hang_up.

DTMF tones can be played to the call using calls_call_send_dtmf_tone Valid characters for the key are 0-9, '*', '#', 'A', 'B', 'C' and 'D'.
