A conference gets considered secure when all participating devices have encrypted signaling and media. The secure conference feature supports SRTP encryption over a secure TLS or IPSec connection. The system provides a security icon for the overall security status of the conference, which is determined by the lowest security level of the participating devices. For example, a secure conference that includes two encrypted connections and one authenticated connection has a conference security status of authenticated. To configure secure ad hoc and meet-me conferences, you configure a secure conference bridge. • If a user initiates a conference call from a phone that is authenticated or encrypted, Unified Communications Manager allocates the secure conference bridge • If a user initiates a call from a phone that is nonsecure, Unified Communications Manager allocates a nonsecure conference bridge.
