7.2 ATA Answer a call
Syntax
Command Description
TA causes remote station to go off-hook (e.g. answer call).
Parameter Description
Connection status
<text> output only if ATX parameter setting with value greater 0.
Notes
• Any additional commands on the same command line are ignored.
• The command may be aborted generally by receiving a character during execution. It can't be aborted in
some connection setup states, such as handshaking.
•if
AT+FCLASS setting is 1 or 2, all incoming calls will be answered as fax calls, if ATA is issued on multiplexer
channel 1 resp. ASC0. For calls explicitly signalled as voice or data calls, this procedure will fail with result
code "NO CARRIER", but the call in question will continue to ring.
It is possible to change the setting for
AT+FCLASS to 0 while the call is ringing, and accept the call normally
afterwards with
ATA.
• The ATA command may be used also to accept a network request for a PDP context activation (see
ATA).
