5.1.5 A, Answer Incoming Call

This command answers an incoming VOICE call after a RING/+CRING indication is sent to the terminal.
If the incoming call is answered (connected), the Module sends a CONNECT notification to the terminal.
If the MT call fails, the possible notifications are:
NO CARRIER - Connection Failure

 ERROR - General Failure
Note: A waiting call (an incoming call while a call is in progress) is announced by +CCWA rather than
RING. A waiting call can be answered only if it is a voice call. The waiting voice call should be answered
