This document summarizes the boot up process and configuration of Cisco IP phones. It describes how the phones use DHCP to obtain an IP address and download configuration files from a TFTP server. It then explains how the phones register with the Cisco CallManager to make and receive calls using SIP or SCCP signaling protocols.

4. Process bootovania telefónu The IP phone powers on The phone performs a Power on Self Test (POST) Through CDP the IP phone learns what the auxiliary VLAN is The phone initializes the IP stack The phone boots up

5. Získanie IP konfigurácie (+TFTP) IP phone send DHCP Discover broadcast requesting an IP address DHCP server selects a free IP address from the pool and sends along with the other scope parameters as a DHCP Offer The IP phone initializes applies the IP configuration to the IP stack The IP phone requests it configuration file from the TFTP server

7. Stiahnutie konfigurácie Step 1 - Phone applies addressing information obtained through DHCP to the IP stack Step 2 - Using the address of the TFTP server learned from the DHCPOffer the phone looks for and downloads the file named SEPAAAABBBBCCCC.cnf.xml (where AAAABBBBCCCC is the MAC address), if the file is found the phone will register Cisco CM is the TFTP Server SEP000F2470AA32.cnf.xml file TFTP request for the SEP000F2470AA32.cnf.xml file MAC 000F.2470.AA32 If no SEP XML file is found go to Step 5 XML SEP

8. Nový Firmware Step 3 - If the firmware version currently on the phone is different than the version specified in the SEPAAAABBBBCCCC.cnf.xml file then the firmware is downloaded from the TFTP server TFTP request for firmware if needed Step 4 - IP phone will reboot if the firmware was updated MAC 000F.2470.AA32 Firmware file 7960 Firmware

9. Neznámy telefón Step 6.1 - The phone will not register to Call Manager Step 5 - If no SEP XML file was found then download from the TFTP server the XMLDefault.cnf.xml file CallManager operates the TFTP Server XMLDefault.cnf.xml file TFTP request for the XMLDefault.cnf.xml file Unknown IP address with MAC 000F.2470.AA32 Step 6.2 - If auto assign is enabled or the phone has been configured then the new IP phone will register to the CallManager and given an extension number (+SEP file is created) or XML Default
