Cisco Systems 6921 manual Deploying a Phone in an Sccp and SIP Environment, Procedure

Chapter

Using Cisco Unified IP Phones with Different Protocols

Procedure

Step 1 Take one of these actions:

•To auto-register the phone, set the Auto Registration Phone Protocol parameter in Cisco Unified Communications Manager Administration to SIP.

•To provision the phone using the Bulk Administration Tool (BAT), choose the appropriate phone model and choose SIP from the BAT.

•To provision the phone manually, make the appropriate changes for SIP on the Phone configuration window in Cisco Unified Communications Manager Administration.

Refer to Cisco Unified Communications Manager Administration Guide for detailed information about Cisco Unified Communications Manager configuration.

Refer to Cisco Unified Communications Manager Bulk Administration Guide for detailed information about using the BAT.

Step 2 If you are not using DHCP in your network, configure the network parameters for the phone. See Configuring Startup Network Settings, page 3-15.

Step 3 Save the configuration updates, click Apply Config, click OK when the Apply Configuration Information dialog displays, then have the user power cycle the phone.

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.

Deploying a Phone in an 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 Auto-Registration parameter is SCCP, perform these general steps:

Procedure

Step 1 Set the Cisco Unified Communications Manager auto_registration_protocol parameter to SCCP.

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

Step 2 Install the phones.

Step 3 Change the Auto Registration Protocol enterprise parameter to SIP. Step 4 Auto-register the SIP phones.
