The Skinny Call Control Protocol (SCCP, or short Skinny) is a proprietary network terminal control protocol originally developed by Selsius Systems.
The SCCP technology is now owned and defined by Cisco Systems. SCCP is a lightweight protocol for session signaling with Cisco Unified Communications Manager (formerly called CallManager). SCCP is used to communicate between IP devices and Cisco Unified Communications Manager. Examples of SCCP clients include the Cisco 7900 series of IP phones, Cisco IP Communicator softphone and the 802.11b wireless Wireless IP Phone 7920, along with Cisco Unity voicemail server. CallManager acts as a signaling proxy for call events initiated over other common protocols such as H.323, Session Initiation Protocol (SIP), ISDN and/or MGCP.

Famous quotes containing the words skinny, call and/or control:
“In those days, the blag slag, the waste of the coal pits, had only begun to cover the side of our hill. Not enough to mar the countryside nor blacken the beauty of our village. For the colliery had only begun to poke its skinny black fingers between the green.”
—Philip Dunne (1908–1992)
“That which we call sin in others, is experiment for us.”
—Ralph Waldo Emerson (1803–1882)
“For the mother who has opted to stay home, the question remains: Having perfected her role as a caretaker, can she abdicate control to less practiced individuals? Having put all her identity eggs in one basket, can she hand over the basket freely? Having put aside her own ambitions, can she resist imposing them on her children? And having set one example, can she teach another?”
—Melinda M. Marshall (20th century)
