The TCP/IP stack can handle incoming calls. This parameter defines how the TCP/IP stack will
behave when receiving an incoming call.
Set Value: AT#ANSWERMODE=<value>
Get Value: AT#ANSWERMODE? or AT#VPHY, AT#VALL
0 Ignore. Ignores the incoming call. In this case, it is the responsibility of the host to accept/not
accept the incoming call by issuing the AT#ACCEPT command.
1 Automatic Answer. The TCP/IP stack goes off hook and accepts the incoming call. As
described below, the calling number must match the one specified in the CALLSCREENNUM
parameter. (The RINGCOUNT parameter must be > 0).
2 Static Callback. The TCP/IP stack ignores the incoming call and then automatically dials
(DIALN1 or DIALN2 determined by the DIALSELECT parameter) by issuing an
AT#CONNECTIONSTART command. The calling number must match the one specified in
the CALLSCREENNUM parameter. The RINGCOUNT parameter must be > 0.
3 Dynamic Callback. The TCP/IP stack ignores the incoming call and then automatically dials
the calling number by issuing an AT#CONNECTIONSTART command. For this feature, the
Caller ID service is mandatory. As described below, the calling number must match the one
specified in the CALLSCREENNUM parameter.

Note: If #ANSWERMODE is set to a value other than 0, the user must enable caller ID. To
enable caller ID, use the command AT+CLIP=1.
This parameter defines the number of seconds the TCP/IP stack will wait before an automatic
call-back operation occurs after receiving an incoming call. It applies only when the
ANSWERMODE parameter is set to an automatic call-back mode (value>1). This timer starts at
the end of the ringing signal.
Set Value: AT#CALLBACKTIMER=<value>
Get Value: AT#CALLBACKTIMER? or AT#VPHY, AT#VALL
Integer between 2 and 255 inclusive. This timer is set in seconds.

When receiving an incoming call, the caller identification (Caller ID) service allows the TCP/IP
stack to identify the phone number of the remote caller. This information is helpful in preventing
unauthorized callers to trigger actions on the TCP/IP stack.
This parameter allows the user to filter the incoming calls when the ANSWERMODE parameter is
set to an automatic mode (value>0). This filtering doesn't apply when the ANSWERMODE
parameter is set to 0. In this case, it is the host's responsibility to accept or reject the incoming
call. If an incoming phone number is not authorized, the TCP/IP stack will ignore it.
Set Value: AT#CALLSCREENNUM=<value>
Get Value: AT#CALLSCREENNUM? or AT#VPHY, AT#VALL
0 Zero. Remote caller not authorized.
* All. No filtering is applied on incoming calls. All remote phone numbers are authorized. This
value must be set to receive incoming calls when Caller ID service is not available.
Not valid for Analog Devices.
Decimal Phone Number. Only the phone number configured here is authorized for incoming
calls. Alphanumeric ASCII text string up to 64 characters.
