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 19). 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).
