This feature lets users share a presentation within ongoing audio or video conversation. The following example describes how presentation sharing works using BFCP: • An ongoing video conversation exists between two video phones. User A decides to share content with User B during the conversation. User A has the option to share the entire screen or share the specific application. • The BFCP stream allows User B to view User A's shared content. An audio-video call with content share requires at least four channels: audio, main video, the second video, and BFCP control channel, to achieve video conferencing and sharing presentations in the second video channel. If the call parties are capable of Far-End Camera Control (FECC), a fifth channel must be established. Presentation Sharing with BFCP From release 12.5(1)SU3 onwards, for Unified Communications Manager registered SIP endpoints, the BFCP work when: • Two video-capable endpoints that start the conversation in audio-only mode share content during the call using BFCP support. • TRP is allocated during the call. BFCP Architecture Presentation sharing using BFCP is supported only on BFCP enabled SIP networks. The entire network, including the endpoint devices and trunks, must be SIP.
