Cisco Unified Communications Manager (formerly named as Cisco Unified
Call Manager) serves as the software-based call-processing component of the
Cisco Unified Communications family of products. A wide range of Cisco Media
Convergence Servers provides high-availability server platforms for Cisco
Unified Communications Manager call processing, services, and applications.
The Cisco Unified Communications Manager system extends enterprise
telephony features and functions to packet telephony network devices such as IP
phones, media processing devices, voice-over-IP (VoIP) gateways, and multimedia
applications. Cisco Unified Communications Manager provides signaling and call
control services to Cisco integrated telephony applications as well as
third-party applications. Cisco Unified Communications Manager performs the
following primary functions:
- Call processing
- Signaling and device
- Dial plan administration
- Phone feature
- Directory services
administration, maintenance, and provisioning (OAM&P)
- Programming interface to
external voice-processing applications such as Cisco IP Communicator, Cisco
Unified Customer Voice Portal (CVP).
The Cisco Unified Communications Manager system includes a suite of
integrated voice applications that perform voice-conferencing and manual
attendant console functions. This suite of voice applications means that no
need exists for special-purpose voice-processing hardware. Supplementary and
enhanced services such as hold, transfer, forward, conference, multiple line
appearances, automatic route selection, speed dial, last-number redial, and
other features extend to IP phones and gateways. Because Cisco Unified
Communications Manager is a software application, enhancing its capabilities in
production environments requires only upgrading software on the server
platform, thereby avoiding expensive hardware upgrade costs.
Distribution of Cisco Unified Communications Manager and all Cisco
Unified IP Phones, gateways, and applications across an IP network provides a
distributed, virtual telephony network. This architecture improves system
availability and scalability. Call admission control ensures that voice quality
of service (QoS) is maintained across constricted WAN link and automatically
diverts calls to alternate public switched telephone network (PSTN) routes when
WAN bandwidth is not available.
A web-browse-able interface to the configuration database provides the
capability for remote device and system configuration. This interface also
provides access to HTML-based online help for users and administrators.
Cisco Unified Communications Manager, designed to work like an
appliance, refers to the following functions:
- Cisco Unified
Communications Manager servers can get pre-installed with software to ease
customer and partner deployment and automatically search for updates and notify
administrators when key security fixes and software upgrades are available for
their system. This process comprises Electronic Software Upgrade Notification.
- You can upgrade Cisco
Unified Communications Manager servers while they continue to process calls, so
upgrades take place with minimal downtime.
- Cisco Unified
Communications Manager supports the Asian and Middle Eastern markets by
providing support for Unicode on higher resolution phone displays.
- Cisco Unified
Communications Manager provides Fault, Configuration, Accounting, Performance,
and Security (FCAPS).
