Part 4 – AT Commands for the SocketModem iCell, SocketModem IP, and MultiModem iCell

Chapter 14

#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,
Default:	0	#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
Responses:	\r\n#SMSPHRASE: "VALUE"\r\n
	\r\nOK\r\n
	\r\nERROR\r\n

Command Example(s):

send : AT#SMSPHRASE="password"\r

reply : \r\nOK\r\n

send : AT#SMSPHRASE?\r

reply : \r\n#SMSPHRASE: "password"\r\n

reply : \r\nOK\r\n
