Cisco IP phones downloads these configuration files from the TFTP server. IP Phones get the IP address of the TFTP server through DHCP.NTP: Use to synchronize time across multiple network devices.

Cisco IP Phone Registration Process1. The 802.3af PoE switch sends a small DC voltage on the Ethernet cable, detects an unpowered 802.3af device, and supplies power to the line.2. The switch delivers voice VLAN information to the Cisco IP Phone using Cisco Discovery Protocol (CDP).3. The IP Phone sends a Dynamic Host Configuration Protocol (DHCP) request on its voice VLAN. The DHCP server replies with IP addressing information, including DHCP Option 150, which directs the IP phone to the TFTP server.4. The IP phone contacts the TFTP server and downloads its configuration file and firmware.5. Based on the IP address listed in the configuration file, the IP phone contacts the call processing server (the CME RYD-GW, in this case), which supports VoIP functions.

Power over EthernetCisco IP Phones support the following options for power:Power over Ethernet: Switches provide power to the IP Phones through the twisted pair cables. There are two standards Cisco Inline Power (pre-standard) and IEEE 802.3af (Industry standard)Midspan Power Injection: Used when the switches are not supporting PoE. Midspan Power Injector sits between the switch and the IP phone and inject the power.Wall power: Wall power needs a DC converter for connecting the Cisco IP Phone to a wall outlet.Configuring and Verifying PoESwitch(config)# interface FastEthernet 0/1Switch(config-if)#power inline {auto | never}

Used for features like call waiting, consultative transfer, and conference.OctoLine: Eight calls at the same time.Ephone and Ephone-dnConfiguring Ephone-dnDual Line Ephone-dn
