Protected Devices Secure Tones You can configure only supported Cisco Unified IP Phones and MGCP E1 PRI gateways as protected devices in Unified Communications Manager. Unified Communications Manager can also direct an MGCP IOS gateway to play secure and non secure indication tones when the system determines the protected status of a call. You can make the following types of calls that use secure and non secure indication tones: • Intracluster IP-to-IP calls • Intercluster calls that the system determines are protected • IP-to-Time-Division-Multiplexing (TDM) calls through a protected MGCP E1 PRI gateway For video calls, the system plays secure and nonsecure indication tones on protected devices. The protected devices provide the following functions: • You can configure phones that are running SCCP or SIP as protected devices. • Protected devices can call non protected devices that are either encrypted or non-encrypted. In such cases, the call specifies non protected and the system plays non secure indication tone to the phones on the call. • When a protected phone calls another protected phone, and the media is not encrypted, the system plays a nonsecure indication tone to the phones on the call. To set a phone to protected state, check the Protected Device check box in the Phone Configuration window of the Cisco Unified CM Administration page.
