Skinny Station Protocol

Skinny Station Protocol SSP is a Cisco proprietary communications protocol based on the industry standard Simple Gateway Control Protocol. Skinny Station Protocol enables communication between first generation IP telephone handsets/Gateways and CallManager servers. Products that support Skinny Station Protocol include the DT-24 and DE-30 gateways, the Catalyst 6000 8-Port T-1/E-1 voice service modules, as well as the Catalyst 6000 24 port FXS module. Skinny Station Protocol relies on the CallManager server to relay configuration and control information. It is built on TCP/IP and utilizes TCP ports 2000-2002.
