The following sections describe your call security options:
Call Security Overview
When a Cisco TelePresence call is in progress, the phone displays the phone number of the called endpoint, or the common phone number if it is a multi-room call. Each Cisco TelePresence endpoint is configured in Cisco Unified Communications Manager, including the maximum security level available for the room. The security level for a specific Cisco TelePresence call is determined by the least secure device joining the call. For example, audio-only calls added to a conference call only support authentication level security.
See Cisco TelePresence System On-Screen Icons and Messages for information about main display screen icons that indicate the level of call security on your system.

Audio-Only Call Security
When an audio-only call is in progress, the phone displays the phone number of the called party. During Cisco TelePresence conference calls, audio-only calls are unsecured. The open lock, as shown in Figure 9-6, indicates that the audio call is not authenticated. See also Figure 9-5.
