To obtain the full benefit of secure conference features, Cisco recommends upgrading Cisco Unified IP Phones to release 8.3 or later, which supports the encryption features in this release. Encrypted phones that run earlier releases do not fully support these new features. These phones can only participate in secure conference as authenticated or nonsecure participants. Cisco Unified IP Phones that are running release 8.3 with an previous release of Cisco Unified Communications Manager will display their connection security status, not the conference security status, during a conference call, and do not support secure conference features like conference list. Warning See topics related to Unified Communications Manager secure conference restrictions for more restrictions that apply to Cisco Unified IP Phones. For additional information about secure conference calls and security icons, refer to the Cisco IP Phone Administration Guide and Cisco IP Phone User Guide for your phone. Secure Conference CTI Support Unified Communications Manager supports secure conference over licensed CTI devices. Refer to the Unified Communications Manager JTAPI Developers Guide and Unified Communications Manager TAPI Developers Guide for this release for more information. Secure Conference Over Trunks and Gateways Unified Communications Manager supports secure conference over intracluster trunks (ICTs), H.323 trunks/gateways, and MGCP gateways; however, encrypted phones that are running release 8.2 or earlier will revert to RTP for ICT and H.323 calls, and the media does not get encrypted. If a conference involves a SIP trunk, the secure conference status is nonsecure. In addition, SIP trunk signaling does not support secure conference notifications to off-cluster participants.
