Cisco Unified IP Phone and Telephony Networks
Cisco Unified IP Phones and 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 to use the other protocol.
Convert New Phone from SCCP to SIP
A new, unused phone uses SCCP. To convert this phone to SIP, perform these steps:
Procedure
Step 1
Take one of these actions:
• To autoregister the phone, set the Auto Registration Phone Protocol parameter in Cisco Unified
• To provision the phone using the Bulk Administration Tool (BAT), choose the appropriate phone model
• To provision the phone manually, make the appropriate changes for SIP on the Phone configuration
Step 2
If you are not using DHCP in your network, configure the network parameters for the phone. See
Settings.
Step 3
To save the configuration updates,
a) Click Apply Config.
b) When the Apply Configuration Information window displays, click OK.
c) Tell the user to power cycle the phone.
In-Use Phone Protocol to Protocol Conversion
Phones using SCCP can be upgraded to use SIP. To change from SCCP to SIP, the phone firmware must be
updated to the recommended SIP version before the phones can register. New Cisco Unified IP Phones ship
from the factory with SCCP phone firmware. These new phones must be upgraded to the recommended SIP
version before they 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, chapter "Cisco Unified IP Phone Configuration", section
"Migration Existing Phone Configuration to a Different Phone".
