CDP (Cisco Discovery Protocol) allows IP phones to receive and/or transmit
device-related information from/to directly connected devices on the network that are
also using the protocol, and store the information about other devices.
When CDP feature is enabled on IP phones, the IP phones periodically advertise their
own information to the directly connected CDP-enabled switch. The IP phones can also
receive CDP packets from the connected switch. When the VLAN configurations on the IP
phones are different from the ones sent by the switch, the IP phones perform an update
and reboot. This allows the IP phones to be plugged into any switch, obtain their VLAN
IDs, and then start communications with the call control.
