4.15 Voice calls
To make the Antares SB

To answer voice calls:
If no voice call is being held, the unit can answer incoming calls as long
as the remote party number is registered on any Phone number-type

nation and the Destination is authorized to receive phone calls. If number
identification service is not provided by the network operator, the autho-
rization process can not take place and the incoming call is rejected. The
unit rejects a call by hanging up immediately after answering.

by the carrier in order for the unit to answer phone calls.
