Skinny Station Protocol

Skinny Station Protocol
Skinny Station Protocol (SSP) is a Cisco communications protocol based on the
industry standard Simple Gateway Control Protocol (SGCP) protocol. SSP was
first introduced as a method of communication between first generation IP telephone
handsets/Gateways (DT-24+/DE-30+) and CallManager servers, and is
still widely used today for that same purpose. Products that support SSP include
the DT-24 and DE-30 gateways, the Catalyst 6000 8-Port T1/E1 voice service
modules, as well as the Catalyst 6000 24 port FXS module. SSP relies on the
CallManager server to relay configuration and control information. It is built on
TCP/IP and utilizes TCP ports 2000–2002.
