Understanding Interactions with Other Cisco Unified IP Communications Products

Understanding Interactions with Other Cisco

Unified IP Communications Products

To function in the IP telephony network, the Cisco Unified IP Phone must be connected to a networking

device, such as a Cisco Catalyst switch. You must also register the Cisco Unified IP Phone with a

Cisco Unified Communications Manager system before sending and receiving calls.

This section includes the following topics:

•

Understanding How the Cisco Unified IP Phone Interacts with Cisco Unified Communications

Manager, page 2-2

•

Understanding How the Cisco Unified IP Phone Interacts with the VLAN, page 2-3

Understanding How the Cisco Unified IP Phone Interacts with Cisco

Unified Communications Manager

Cisco Unified Communications Manager is an open and industry-standard call processing system. Cisco

Unified Communications Manager software sets up and tears down calls between phones, integrating

traditional PBX functionality with the corporate IP network. Cisco Unified Communications Manager

manages the components of the IP telephony system—the phones, the access gateways, and the resources

necessary for such features as call conferencing and route planning. Cisco Unified Communications

Manager also provides:

•

Firmware for phones

•

Authentication and encryption (if configured for the telephony system)

•

Configuration file and CTL file, via TFTP service

•

Phone registration

•

Call preservation, so that a media session continues if signaling is lost between the primary Cisco

Unified Communications Manager and a phone)

For information about configuring Cisco Unified Communications Manager to work with the IP devices

described in this chapter, refer to

Cisco Unified Communications Manager Administration Guide

Cisco

Unified Communications Manager System Guide

, and to

Cisco Unified Communications Manager

Security Guide.

For an overview of security functionality for the Cisco Unified IP Phone, see the

“Understanding

Security Features for Cisco Unified IP Phones” section on page 1-7

Note

If the Cisco Unified IP Phone model that you want to configure does not appear in the Phone Type

drop-down list in Cisco Unified Communications Manager Administration, go to the following URL and

install the latest support patch for your version of Cisco Unified Communications Manager:
