Feature Overview

Cisco Unified IP Phones provide traditional telephony functionality, such as call

forwarding and transferring, redialing, speed dialing, conference calling, and

voice messaging system access. Cisco Unified IP phones also provide a variety of

other features. For an overview of the telephony features that the

Cisco Unified IP Phone supports, see the

“Telephony Features Available for the

Phone” section on page 5-2

As with other network devices, you must configure Cisco Unified IP Phones to

prepare them to access Cisco Unified Communications Manager and the rest of

the IP network. By using DHCP, you have fewer settings to configure on a phone,

but if your network requires it, you can manually configure an IP address, TFTP

server, and subnet mask. For instructions on configuring the network settings on

the Cisco Unified IP Phones, see

Chapter 4, “Configuring Settings on the Cisco

Unified IP Phone.”

The Cisco Unified IP Phone can interact with other services and devices on your

IP network to provide enhanced functionality. For example, you can integrate the

Cisco Unified IP Phones with the corporate Lightweight Directory Access

Protocol 3 (LDAP3) standard directory to enable users to search for co-workers

contact information directly from their IP phones. You can also use XML to

enable users to access information such as weather, stocks, quote of the day, and

other web-based information. For information about configuring such services,

see the

“Configuring Corporate Directories” section on page 5-24

and the

“Setting Up Services” section on page 5-27

Finally, because the Cisco Unified IP Phone is a network device, you can obtain

detailed status information from it directly. This information can assist you with

troubleshooting any problems users might encounter when using their IP phones.

See

Chapter 7, “Viewing Model Information, Status, and Statistics on the Cisco

Unified IP Phone,”

for more information.
