BFCP Screen Share
Applies to Cisco Jabber desktop clients, Cisco Jabber for mobile clients can only receive BFCP screen shares.
Binary Floor Control Protocol (BFCP) screen share is controlled by Cisco Unified Communications Manager. Cisco Unified Communications Manager handles the BFCP packets that users transmit when using video desktop sharing capabilities. When on a call selectto start a BFCP screen share.
Remote screen control is not supported with this feature.
Video desktop sharing using BFCP is not supported if Trusted Relay Point or Media Termination Point are enabled on the software phone device.
In Jabber for Windows, the Screen Share button starts a BFCP screen share by default. If BFCP-based sharing is unavailable, the button starts an IM-only screen share if possible.
IM Only Screen Share
Applies to Cisco Jabber for Windows.
IM-only screen share is a one-to-one screen share that uses RDP. The EnableP2PDesktopShare parameter controls whether IM-only screen shares are available. The PreferP2PDesktopShare parameter controls whether Jabber prefers video sharing or IM-only screen shares.
If your deployment allows IM-only screen share, selectin the chat window to start a screen share.
By default, RDP requires port 3389 be open. Jabber has a default port range of 49152–65535 for IM-only screen share. You can use the SharePortRangeStart and SharePortRangeSize parameters to restrict the port range.
Escalate to a Meeting and Share
