Call Privacy Indication Unsolicited Response +WPRV
Multi-Tech Systems, Inc. CDMA C1 AT Commands Reference Guide (PN S000478C)
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.
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 response +WPRV: 1 will appear indicating
the long code PN mask for the traffic channel has been scrambled by the base station. This
command may be issued before or during a voice call.
Note:
privacy changes (loss or establishment).
Command Syntax: AT+WPRV=<voice privacy level>
<voice privacy level>
This response confirms that the call privacy level has changed during a call.
