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.
Call 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.
