Cisco Unified Communications Manager Interaction
Cisco Unified Communications Manager is an open, 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 telephony system, such as 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
-
Certificate Trust List (CTL) and Identity Trust List (ITL) files using the TFTP and HTTP services
-
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 phones described in this chapter, see the documentation for your particular Cisco Unified Communications Manager release.
Note |
If the phone model that you want to configure does not appear in the Phone Type drop-down list in Cisco Unified Communications Manager Administration, install the latest device package for your version of Cisco Unified Communications Manager from Cisco.com. |
