Chapter 2 Preparing to Install the Cisco Unified IP Phone on Your Network

Understanding the Phone Startup Process

A phone accesses a default configuration file named XmlDefault.cnf.xml from the TFTP server when these conditions exist:

•You have enabled auto-registration in Cisco Unified Communications Manager

•The phone has not been added to the Cisco Unified Communications Manager Database

•The phone is registering for the first time

If auto registration is not enabled and the phone has not been added to the Cisco

Unified Communications Manager database, the phone registration request will be rejected. In this case, the phone resets and attempts to register repeatedly.

If the phone has registered before, the phone accesses the configuration file named

SEPmac_address.cnf.xml, where mac_address is the MAC address of the phone.

For SIP phones, the TFTP server generates these SIP configuration files:

•SIP IP Phone:

–For unsigned and unencrypted files—SEP<mac>.cnf.xml

–For signed files—SEP<mac>.cnf.xml.sgn

–For signed and encrypted files—SEP<mac>.cnf.xml.enc.sgn

•Dial Plan—<dialplan>.xml

•Softkey Template—<softkey_template>.xml

The filenames are derived from the MAC Address and Description fields in the Phone Configuration window of Cisco Unified Communications Manager Administration. The MAC address uniquely identifies the phone. For more information refer to Cisco Unified Communications Manager Administration Guide.

For more information about how the phone interacts with the TFTP server, refer to Cisco Unified Communications Manager System Guide, “Cisco TFTP” chapter.

Understanding the Phone Startup Process

When connecting to the VoIP network, the Cisco Unified IP Phone goes through a standard startup process, as described in Table 2-4. Depending on your specific network configuration, not all of these process steps may occur on your Cisco Unified IP Phone.
