The Cisco IP Phones 8800 Series provides voice communication over an Internet Protocol (IP) network. The Cisco IP Phone functions much like any digital business phone, allowing you to make phone calls and to access features such as mute, hold, transfer, and more. In addition, because the phone connects to your data network, it offers enhanced IP telephony features, including access to network information and services, and customizable features and services.
The Cisco IP Phone 8811 has a grayscale LCD screen. The Cisco IP Phones 8841, 8845, 8851, 8851NR, 8861, 8865, and 8865NR have a 24-bit color LCD screen.
When adding features to the phone line keys, you are limited by the number of line keys available. You cannot add more features than the number of line keys on your phone.

For additional information on Video Calls, see Cisco IP Phone 8800 Series User Guide for Cisco Unified Communications Manager and the documentation for your particular Cisco Unified Communications Manager release.
Like other devices, a Cisco IP Phone must be configured and managed. These phones encode and decode the following codecs:
- G.711 a-law
- G.711 mu-law
Using a cell,
mobile, or GSM phone, or two-way radio in close proximity to a Cisco IP Phone
might cause interference. For more information, see the manufacturer’s
documentation of the interfering device.
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.
As with other
network devices, you must configure Cisco 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. If your network requires
it, however, you can manually configure information such as: an IP address,
TFTP server, and subnet information.
Cisco IP Phones can
interact with other services and devices on your IP network to provide enhanced
functionality. For example, you can integrate Cisco Unified Communications
Manager with the corporate Lightweight Directory Access Protocol 3 (LDAP3)
standard directory to enable users to search for coworker 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
Finally, because the Cisco 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. You can also obtain statistics about an active call or firmware versions on the phone.
To function in the
IP telephony network, the Cisco IP Phone must connect to a network device, such
as a Cisco Catalyst switch. You must also register the Cisco IP Phone with a
Cisco Unified Communications Manager system before sending and receiving calls.
