Cisco® Collaboration Solutions facilitate rich interactions between distributed and mobile users that enhance team performance, encourage innovation, improve productivity, and accelerate the decision-making process.

Product Overview

Cisco Unity® Connection is a voicemail and unified messaging platform with a comprehensive feature set that is based on the same Linux Unified Communications Operating System as Cisco Unified Communications Manager (Cisco UCM). With Cisco Unity Connection, you can access and manage voice messages in a variety of ways using your email inbox, web browser, Cisco Jabber® messaging integration platform, Cisco Unified IP Phone, smartphone, tablet, and more. Cisco Unity Connection also provides robust speech-recognition features for when you are mobile, so you can manage your voice messages hands and eyes free.

Features and Benefits

Accelerate collaboration: Cisco Unity Connection is a powerful unified messaging system with many advanced capabilities that you can customize to increase your individual and team productivity. Respond quickly to colleagues and partners by using speech-activated tools. Easily prioritize and manage messages, access meetings on your calendar, and connect to colleagues simply by saying their names.

Access voicemail anytime and anywhere: Access your Cisco Unity Connection voice messages the way you prefer, whether from an IP phone, mobile phone, tablet, web browser, email client, or desktop client such as the Cisco Jabber application. You can also use Cisco SpeechView to have your voice messages transcribed and delivered to your email inbox.

Reduce total cost of ownership (TCO): Simplify your deployment efforts with the Cisco Unity Connection solution on a Linux appliance. Enjoy the flexibility to deliver unified messaging, integrated messaging, or simply voicemail. The flexible user interface makes messaging more efficient for power users and occasional voicemail users alike. Cisco Unity Connection works in a variety of messaging environments using standard protocols.

Deploy a reliable solution: With years of successful deployments, Cisco Unity Connection is a tested, reliable solution. Take advantage of redundancy to make sure you never miss a voicemail. 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.

Assure branch-office survivability: Centralization of your voice infrastructure reduces maintenance costs and simplifies management, but if the WAN is disrupted, your branch offices risk losing their voice messaging and Automated-Attendant services. The Cisco Unity Connection Survivable Remote Site Voicemail (SRSV) solution eliminates these concerns by helping assure that branch-office voicemail and Automated-Attendant functions are always available, even when connectivity to your a central data center is lost.

Survivable Remote Site Voicemail complements the Cisco Unified Survivable Remote Site Telephony (SRST) solution by offering an easy-to-deploy, centrally provisioned, voicemail and Automated-Attendant survivable branch-office solution that runs on existing branch-office hardware. Survivable Remote Site Voicemail is a feature of Cisco Unity Connection, meaning no other software products or third-party solutions are required to make it work.

Secure your messages: Security is a concern for most organizations, and mandatory for others. Cisco Unity Connection keeps your messages highly secure so someone outside your organization cannot access or play them.

Offer speech-enabled messaging: To increase 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, natural speech commands.

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, please refer to the data sheet at:

The Cisco SpeechView feature converts voice messages to text and delivers the text version of the voice message to your email inbox, allowing you to read your voice messages and take immediate action. To learn more, please refer to the data sheet at:

Virtualize your environment: Cisco Unity Connection runs on a virtualized server and is deployed on any hardware that meets minimum specifications. Cisco Unity Connection supports virtualization on Fibre Channel, Fibre Channel over Ethernet (FCoE), Small Computer System Interface over IP (iSCSI), and Network File Storage (NFS) SANs. For more information, please refer to
