#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 
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
