A, Answer Incoming Call

This command answers an incoming VOICE/DATA/FAX call after a RING/+CRING indication
is sent to the terminal.
If the incoming call is answered (connected), the G24-L sends a CONNECT notification to the
terminal.
If the MT call fails, the possible notifications are:
•
NO CARRIER - Connection Failure
•
ERROR - General Failure

Indication
This command controls whether or not to present the extended format of an incoming call
indication. The RING/+CRING indication is sent from the G24-L to the terminal when the G24-L
is alerted by an incoming call from the network. Once this indication is sent, information is
available on the calling line via +CLIP. When +CRC is disabled, the indication is RING, and
when +CRC is enabled, the indication is +CRING.
April 15, 2008
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 using the ATA command, which will put the active call on
hold and will connect the waiting call, making it the active call. This ATA action is the
same action as AT+CHLD=2.
//VOICE call connected - G24-L is in Command mode
//Connecting (dots are not displayed)
//DATA call connected - G24-L is in Online Data mode
In a CSD call, call release is not valid during the phase of call negotiation (from OK until
connect call).
