Feature Overview
Cisco IP Phones provide traditional telephony functionality, such as call
forwarding and transferring, redialing, speed dialing, conference calling, and
voice messaging system access. Cisco IP phones also provide a variety of other
features. For an overview telephony features the Cisco IP Phone models
7902G/7905G/7912G support, and for tips on configuring them, see the

Like other network devices, you must configure the Cisco IP Phones to prepare
them to access Cisco CallManager and the rest of the IP network. Using DHCP,
you have fewer settings to modify, but you can choose to assign a static IP if your
network requires it. For instructions on configuring the network settings on the
Cisco IP Phones, see Chapter 4, “Configuring Network Settings on the
