What is SCCP?

Skinny Client Control Protocol (SCCP) is a Cisco proprietary protocol used for communication between Cisco Unified Communications Manager (CUCM) and IP phones. It facilitates call control signaling, allowing phones to register with CUCM, initiate calls, receive calls, and access telephony features. While SIP is now more prevalent, SCCP was widely used in Cisco environments.
