140 Nortel IP Phone 1220

If power to the phone is interrupted after you install and configure an IP

phone, you are not required to reenter the IP Parameters, Node Numbers,

or Terminal Number (TN). There is also no need to again acquire the

firmware.

Description

The IP Phone 1220 uses the customer IP data network to communicate

with the Communication Server 1000 (CS 1000). The IP Phone 1220

translates voice into data packets for transport using Internet Protocol.

Use a Dynamic Host Configuration Protocol (DHCP) server to provide

information that you can use for the IP Phone 1220 network and CS 1000

connections.
