Set Voice Privacy Level +WPRV
Description: This command requests the CDMA voice privacy level. CDMA voice privacy is an optional feature of CDMA
networks. Therefore, voice privacy will only become enabled during a voice call if the base station supports
voice privacy; otherwise this feature is unavailable on your CDMA carrier. Thus, this command enables a
request from the modem to the base station for voice privacy. If voice privacy is activated by the base
station, the unsolicited command +WPRV:1 will appear indicating the long code PN mask for the traffic
channel has been scrambled by the base station (also see Chapter 18). This command may be issued
before or during a voice call.
Note: When voice privacy is enabled, an audible alert will be generated if the state of voice privacy changes (loss
or establishment).
Values: <voice privacy level>
0 Normal (default)
1 Private
Syntax: Command syntax: AT+WPRV=<voice privacy level>
Command Possible Responses
