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 features such as call conferencing and route planning. Cisco Unified
Communications Manager also provides:
•
Firmware for phones
•
Configuration file via TFTP service
•
Phone registration
•
Call preservation, so that a media session continues if signaling is lost between the primary
Communications Manager and a phone
For information about configuring Cisco Unified Communications Manager to work with the IP devices
described in this chapter, go to the
Cisco Unified IP Phone Configuration

If a computer is connected to the access port, the computer and the phone share the same physical link
to the switch and share the same port on the switch. This shared physical link has the following
implications for the VLAN configuration on the network:
