Cisco Unity Connection

Cisco Unity Connection 8.0 Data Sheet

Cisco® Unified Communications Solutions unify voice, video, data, and mobile applications on fixed and mobile networks, enabling easy collaboration every time from any workspace.

Product Overview

Cisco Unity® Connection is a feature-rich voice messaging platform based on the same Linux Unified Communications Operating System as Cisco Unified Communications Manager. With Cisco Unity Connection, you can access voice messages using Cisco Unified Personal Communicator, or use the display on your Cisco Unified IP Phone to view, search, sort, and play messages. Cisco Unity Connection also provides robust Automated-Attendant functions that include intelligent call routing and easily customizable call-screen and message-notification options.

Features and Benefits

Powerful Voice Messaging

At its core, Cisco Unity Connection is a powerful voice messaging system with many advanced capabilities that you can customize to maximize your individual and team productivity. You can personalize communications options and interact with the system to manage calls and messages in the way that is most comfortable and convenient for you. The flexible user interface makes messaging more efficient for "power users" and occasional voicemail users alike. For example, you can even customize your telephone user interface (TUI) and touchtone mappings to make migration from traditional voicemail systems much easier.

Speech-Enabled Messaging and Automated Attendant

To maximize the productivity of mobile workers, Cisco Unity Connection offers a natural and robust speech-activated user interface that allows you to browse and manage your voice messages using simple, naturual speech commands.

In addtion, the Speech Connect for Cisco Unity Connection feature is a built-in speech-enabled Automated Attendant that enables you to call other Cisco Unity Connection users or personal contacts by simply using your voice. To learn more about Speech Connect for Cisco Unity Connection, please refer to the data sheet:

Powerful Desktop Message Access

Manage your voice messages from a variety of devices and locations, whichever best suits the way you work.

   Cisco Unified Personal Communicator voicemail integration

     You can access your voice messages directly from the Cisco Unified Personal Communicator client.

     You can use the integrated media player to play and delete messages.

     You can easily access presence and availability information about the person you are calling in the Cisco Unified Personal Communicator client; then click to call the person back and escalate to web chat, video, or other multimedia session.

   Cisco Unity Connection Inbox web browser interface to voice messages

     You can view, sort, play, compose, forward, and reply to voice messages.

     You can use the digital video recorder (DVR)-style interface to play, rewind, pause, or fast forward messages.

     You can easily address messages to multiple recipients and distribution lists.

     Voice messages in the Cisco Unity Connection Inbox are synchronized with the message-waiting indicator (MWI) on your telephone.

     Web browser-based tools are supported on Internet Explorer, Firefox, and Safari.

   Internet Message Access Protocol (IMAP)-based email client to access voice messages

     You can access email and voicemail messages and play and delete voice messages from within the same desktop email client using the built-in ViewMail for Outlook or ViewMail for Notes player.

     Voice messages in your email inbox are synchronized with the MWI on your telephone.

     Various standards-based desktop email clients are supported, including Microsoft Outlook, Lotus Notes, and Entourage for Mac.

     You can compose, reply to, and forward messages by using IMAP clients.

   Visual voicemail on your Cisco Unified IP Phone

     You can view, sort, play, compose, forward, and reply to voice messages from the screen on your IP phone without having to dial in to the system.

Personal Web Administration

Cisco Unity Connection allows you to customize your personal settings from a web browser using the Cisco Unity Connection Assistant, a dynamic interface in the browser-based Cisco Personal Communications Assistant (PCA). You can quickly and easily establish or change personal settings such as your voicemail options, security codes, personal distribution lists, and message-delivery options. You can also use the web administration interface to define and manage personal call-transfer rules to customize the delivery of incoming calls based on caller, time of day, or calendar status.

Simplified Installation, Configuration, and Maintenance

Running on the Cisco Linux-based appliance platform, Cisco Unity Connection uses a common set of management and serviceability tools designed to provide a consistent experience and to streamline the ongoing management and operation of a Cisco Unified Communications System.

Cisco Unity Connection 8.0 can be networked with Cisco Unity 8.0, allowing both solutions to work transparently together as a single system. Administrators have a single view of Cisco Unity Connection and Cisco Unity voicemail boxes regardless of which server the voicemail box resides on. Distribution lists, locations, and search spaces may all be shared, and cross-box features such as logins and transfers are also supported between the two systems.

A centralized Cisco Unity Connection 8.0 application combined with the Cisco Unified Messaging Gateway 8.0 and a Cisco Unity Express 8.0 messaging solution at a branch-office location allows you to enable Cisco Unified Survivable Remote Site Voicemail. This solution uses Cisco Unity Express at the branch office to manage voice messages if the WAN to the centralized Cisco Unity Connection solution is down. Then, Cisco Unified Survivable Remote Site Voicemail restores voice messages to the central server when WAN service returns. For more information about Cisco Unified Survivable Remote Site Voicemail, please refer to the data sheet at:
