Voice Privacy Service Tutorial

This tutorial describes how to use the voice privacy service in CDMA networks.

The Voice Privacy service encodes the transmitted signal to help prevent eavesdropping on the call. The Voice Privacy service is CDMA-specific. The calls set up during CDMA mode can request privacy to be on or off and this request may or may not be granted depending on network support. In GSM mode, privacy is requested by default but it may not be possible to provide if the network operator does not support it or a country does not allow it.

Use RMobileCall::SetPrivacy() to set the voice privacy on or off.
Use RMobileCall::NotifyPrivacyConfirmation() to get the notification of any changes in the voice privacy service.
