Step 1: Telephone to Network

The telephone is appropriately installed and powered. After a short initialization process, the telephone identifies the LAN speed. If applicable to your network and telephone model, 802.1X Supplicant authentication occurs at this time, where an 802.1X ID and password have to be submitted to proceed. Then the telephone sends a DHCP message out into the network, identifying itself and requesting further information. Depending on your network structure, the message goes directly to the DHCP server or a network router receives the message and relays it to the appropriate DHCP server.
