Explanation

Cisco Expressway (and its predecessor, Cisco TelePresence VCS) is a video and voice collaboration gateway that natively supports two call-control and signaling protocols for its zones: SIP (Session Initiation Protocol) and H.323. These are the industry-standard VoIP and video conferencing protocols that Expressway uses to establish, manage, and route calls. The other protocols listed - H.248 (MEGACO), MGCP (Media Gateway Control Protocol), and SCCP (Skinny Client Control Protocol) - are endpoint/gateway control protocols used by Cisco UCM for managing IP phones and gateways. They are not supported as zone protocols on Expressway.
