Converting an In-Use Phone from One Protocol to the Other Protocol
If Cisco Unified IP phones presently connected to Cisco Unified CM are using the SCCP protocol to
receive and place calls and you now want some or all of these phones to use the SIP protocol, the phone
firmware for each phone type must be upgraded from SCCP to the recommended SIP version before the
phones can register. If Cisco Unified IP phones to be connected to Cisco Unified CM are brand new,
out-of-the-box, the SCCP phone firmware preloaded at the factory must be upgraded to the
recommended SIP version before your SIP phones can complete registration.
For information about how to convert an in-use phone from one protocol to the other, see the Cisco
Unified Communications Manager Administration Guide, Cisco Unified IP Phone Configuration,
section Migration Existing Phone Configuration to a Different Phone.
