'''SCCP''' is a proprietary terminal control protocol originally developed by Selsius Corporation. It is now owned and defined by [[Cisco Systems, Inc.]] as a messaging set between a skinny client and the Cisco [[CallManager]]. Examples of skinny clients include the Cisco 7900 series of IP phone such as the [[Cisco 7960]], [[Cisco 7940]] and the [[802.11b]] wireless [[Cisco 7920]]. Skinny is a lightweight protocol which allows for efficient communication with Cisco Call Manager. whichCall mayManager actacts as a signalling proxy for signalling of call events withinitiated over other common protocols such as [[H.323]], [[SIP]], [[ISDN]] and/or [[MGCP]].

A skinny client uses [[TCP/IP]] to and from one or more Call Managers in a cluster. RTP/[[User Datagram Protocol|UDP]]/IP is used to and from a similar skinny client or H.323 terminal for the bearer traffic (real-time audio stream). SCCP is a stimulus-based protocol and is designed as a communications protocol for hardware endpoints and other embedded systems, with significant CPU and memory constraints.
