Universal IP AT Commands Reference Guide (Document S000457K) 75
#ANSWERMODE – Set Answering Mode
Description: The TCP/IP stack can handle incoming calls. This parameter defines how the TCP/IP stack will
behave when receiving an incoming call.
Syntax: AT#ANSWERMODE=<value>
AT#ANSWERMODE? Read or display the current setting (or AT#VPHY, AT#VALL).
Values: 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.
4 - Automatic Connection Using SMS. The TCP/IP stack matches the message from an
incoming SMS message to the #SMSPHRASE parameter. If a match occurs,
#CONNECTIONSTART is issued. (The RINGCOUNT parameter must be 0).
Default: 0
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.
Note: A wake-up SMS message will NOT work if the device is busy.
#SMSPHRASE – Set Incoming SMS Phrase
Description: When receiving an incoming SMS and #ANSWERMODE=4, the SMS message allows the
TCP/IP stack to identify a specific message from the sender. This information is helpful in
preventing unauthorized SMS to trigger actions on the TCP/IP stack.
Notes: A setting of 0 (zero) disables all remote SMS messages.
This command is for all devices except the SocketWireless Wi-Fi (MT810SWM-IP)
Syntax: AT#SMSPHRASE="<parameter1>"
AT#SMSPHRASE? Read or display the current setting.
Values: parameter 1
value = 160 character alphanumeric string
