Using Cisco Unified IP Phones with Different Protocols
The Cisco Unified IP Phone can operate with SCCP (Skinny Client Control Protocol) or SIP (Session
Initiation Protocol). You can convert a phone that is using one protocol for use with the other protocol.
This section includes these topics:
• Converting a New Phone from SCCP to SIP, page 2-11
• Converting an In-Use Phone from One Protocol to the Other Protocol, page 2-11
• Deploying a Phone in an SCCP and SIP Environment, page 2-12
