Explanation

Cisco VCS (Video Communication Server) is a call control and signaling platform for video collaboration. B is correct because VCS provides SIP-H.323 interworking, allowing endpoints using different protocols to communicate. D is correct because VCS integrates with Cisco Unified Communications Manager (CUCM) via SIP trunks, enabling unified dial plans between video and voice infrastructure. E is correct because VCS supports registration of third-party standards-based H.323 and SIP devices, making it protocol-agnostic and vendor-neutral. A is incorrect because SCCP (Skinny Client Control Protocol) is a Cisco-proprietary protocol for IP phones and is not a native VCS feature. C is incorrect because native scheduling is a function of Cisco TelePresence Management Suite (TMS), not VCS. F is incorrect because reverse proxy is not a core VCS function; traversal and firewall traversal are handled by VCS Expressway, but it is not classified as a reverse proxy.
