Cisco 7942G Phone Guide

An Overview of Your Phone
Cisco Unified IP Phone 7962G and 7942G Phone Guide for Cisco Unified Communications Manager 6.1(3) (SCCP and SIP)
Understanding SIP vs. SCCP
Your phone can be configured to work with one of two signaling protocols: SIP (Session Initiation
Protocol) or SCCP (Skinny Call Control Protocol). Your system administrator determines this
configuration.
Phone features can vary depending on the protocol. This Phone Guide indicates which features are
protocol-specific. To learn which protocol your phone is using, you can ask your system administrator
or you can choose > Model Information > Call Control Protocol on your phone.
