When a phone requests service from Cisco Unified CME, the registrar confirms the username, i.e. the phone number for the phone. The phone accesses its configuration profile on the TFTP server, typically the Cisco Unified CME router, and processes the information contained in the file, registers itself, and puts the phone number on the phone console display.
Minimally, a configuration profile contains the MAC address, the type, and the number phone number that is permitted by the registrar to handle the Register message for a particular Cisco Unified IP phone.
Any time you create or modify parameters for either an individual phone or a directory number, generate a new phone configuration to properly propagate the parameters.
