Cisco Unified IP Phones and Different Protocols

 

The Cisco Unified IP Phones can operate with Skinny Client Control Protocol (SCCP) or Session Initiation Protocol (SIP). You can convert a phone from using one protocol to using the other protocol.

 

Convert New Phone from SCCP to SIP

A new, unused phone is set for SCCP by default. 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 enterprise parameter in Cisco Unified Communications Manager Administration to SIP.
  • To provision the phone by using the Bulk Administration Tool (BAT), choose the appropriate phone model and choose SIP from BAT.
  • To provision the phone manually, make the appropriate changes for SIP on the Phone Configuration window in Cisco Unified Communications Manager Administration.

 

For more information on Cisco Unified Communications Manager configuration, see Cisco Unified Communications Manager Administration Guide. For more information on using BAT, see Cisco Unified Communications Manager Bulk Administration Guide.

 

Step 2

If you are not using DHCP in your network, configure the network parameters for the phone.

 

Step 3

Save the configuration updates, click Apply Config, click OK in the Apply Configuration Information window, and have the user power cycle the phone.

In-Use Phone Protocol to Protocol Conversion

For information on 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” chapter, “Migrate existing phone settings to another phone” section.

 

Deploy Phone in SCCP and SIP Environment

To deploy Cisco Unified IP Phones in an environment that includes SCCP and SIP and in which the Cisco Unified Communications Manager autoregistration parameter specifies SCCP, perform these general steps:

 

Procedure

Step 1

Set the Cisco Unified Communications Manager auto_registration_protocol parameter to SCCP.

 

Step 2

From Cisco Unified Communications Manager, choose System > Enterprise Parameters.

 

Step 3

Install the phones.

 

Step 4

Change the Auto Registration Protocol enterprise parameter to SIP.

 

Step 5

Autoregister the SIP phones.
