Flexible User Interface

There are two ways in which users can interact with Cisco Unity Connection by phone:

Phone keypad keys—Users press keys on any touchtone phone to respond to prompts or select menu options.

Voice commands—Users speak into the phone handset, headset, or speakerphone, and Connection responds to their voice commands. Users have the option to press keys on the phone keypad for a primary set of commands rather than say a voice command.

The Connection conversations can be customized both by administrators and by end users to maximize company and individual productivity. Users can configure the system to manage calls and messages in the way that is most comfortable and convenient for them, which makes messaging more efficient for "power users" and occasional voicemail users alike. In addition, for users who are accustomed to third-party voicemail conversations, Connection offers multiple conversation keypad mappings that can be further customized, as well as the option to create a new conversation by using the Custom Keypad Mapping tool.

To maximize the productivity of mobile workers, consider enabling the speech-activated voice command interface. This interface allows users to browse and manage voice messages and to call other Connection users or personal contacts by using simple, natural speech commands.

The phone interface also allows for access to Microsoft Exchange calendars, contacts, and emails, and to Cisco Unified MeetingPlace and Cisco Unified MeetingPlace Express meetings.

Automated Attendant Functionality

Cisco Unity Connection includes a full-featured automated attendant that is customizable to suit the needs of your organization. Connection provides a number of different call management elements that you can combine to customize how your system handles calls and collects input from callers. You can use the default configuration to play a company greeting to callers, allow them to enter user extensions or reach a directory of users, or reach an operator. Or, you can add and customize additional elements to create complex audio-text trees that can ask callers a series of questions and record their responses, offer tiered menus of product information, route calls to a support queue during working hours and to a mailbox after hours, immediately play legal disclaimers or "snow day" recordings to all callers before allowing them to interact with the system, and so on.

For information on call management in Cisco Unity Connection and the various elements that make up the Connection conversation such as call handlers, directory handlers, interview handlers, call routing tables, schedules and holidays, and restriction tables, see the System Administration Guide for Cisco Unity Connection Release 7.x. Also in that guide is information on creating a call management plan, how outside callers and users interact with the Connection conversation, and how administrators and users can customize the Connection conversation. The guide is available at http://www.cisco.com/en/US/docs/voice_ip_comm/connection/7x/administration/guide/7xcucsagx.html.

Dial Plan Flexibility: Partitions and Search Spaces

Dial plan flexibility is supported through the use of partitions and search spaces, with which you can segment the Cisco Unity Connection directory for both dialing and addressing. For example, partitions and search spaces can be configured to allow for overlapping extensions, abbreviated dialing, or multi-tenant configurations.

For more information on using partitions and search spaces, see the "Managing Partitions and Search Spaces" chapter of the System Administration Guide for Cisco Unity Connection Release 7.x.

Languages

When multiple languages are installed, you can configure the language for system prompts that are played to users and callers. Separate greetings can be recorded for users and call handlers in each language that is installed on the system. Routing rules can be configured to set the language for a call based on how the call reached the system.

For a list of supported languages, see the "Available Languages for Cisco Unity Connection Components" section of System Requirements for Cisco Unity Connection Release 7.x at http://www.cisco.com/en/US/docs/voice_ip_comm/connection/7x/requirements/7xcucsysreqs.html.

Access to Calendar, Meeting, and Contact Information

When Cisco Unity Connection is configured for a calendar integration, users can access calendar and meeting information from Cisco Unified MeetingPlace, Cisco Unified MeetingPlace Express, and Microsoft Exchange, and can import Exchange contacts for use by rules created in the Personal Call Transfer Rules web tool and for use by voice commands when placing outgoing calls.

For more information, see the "Creating Calendar Integrations" chapter of the System Administration Guide for Cisco Unity Connection Release 7.x.

Access to Emails in an External Message Store

When Cisco Unity Connection is configured to connect to an external message store (a message store other than Connection), users can hear their emails read to them by the Text to Speech (TTS) feature when they log on to Connection by phone. For more information, see the "Configuring Access to Emails in an External Message Store" chapter of the System Administration Guide for Cisco Unity Connection Release 7.x.

Desktop Message Access

Cisco Unity Connection supports access to voice messages through a wide range of desktop clients, including:

IMAP clients—Third-party IMAP clients such as email clients are supported for accessing voice messages from Connection. Users can read, reply to, and forward messages from these types of clients. For more information, see the "Configuring IMAP Settings" chapter of the System Administration Guide for Cisco Unity Connection Release 7.x.

Cisco Unity Connection ViewMail for Microsoft Outlook plug-in—In addition to basic IMAP access to Cisco Unity Connection voice messages, the Cisco Unity Connection ViewMail for Microsoft Outlook form allows playing and recording messages by using either the phone or workstation speakers and microphones. Users can compose, read, reply to, and forward messages when using ViewMail. For more information on the ViewMail for Outlook client, see the User Guide for Accessing Cisco Unity Connection Voice Messages in an E-Mail Application at http://www.cisco.com/en/US/docs/voice_ip_comm/connection/7x/user/guide/email/7xcucugemailx.html, and the "Configuring Cisco Unity Connection ViewMail for Microsoft Outlook" section in the "Configuring an Email Account to Access Cisco Unity Connection Voice Messages" chapter of the User Workstation Setup Guide for Cisco Unity Connection Release 7.x.

Cisco Unity Inbox—The Cisco Unity Inbox is a web tool available on the Cisco Personal Communications Assistant (PCA) website. Users can compose, read, reply to, and forward messages from the Cisco Unity Inbox. For more information, see the User Guide for the Cisco Unity Connection Inbox Web Tool at http://www.cisco.com/en/US/docs/voice_ip_comm/connection/7x/user/guide/inbox/7xcucuginboxx.html.

Cisco Unified Personal Communicator—Cisco Unified Personal Communicator is a desktop client that allows users to play voice messages. Users can read and delete messages from Cisco Unified Personal Communicator. For more information, see the CUPC product pages at http://www.cisco.com/en/US/products/ps6844/tsd_products_support_series_home.html.

Cisco Unified Messaging with IBM Lotus Sametime—Cisco Unified Messaging with IBM Lotus Sametime integrates Connection voicemail into the IBM Lotus Sametime instant messaging application, allowing users to play their voice messages within Lotus Sametime. A list of all voice messages, including the caller name or number and the date and time, are displayed in a panel on the client window. Users simply click to play their voice messages. They can also sort and delete messages directly from the Lotus Sametime application. For more information, see the Release Notes for Cisco Unified Messaging with IBM Lotus Sametime at http://www.cisco.com/en/US/products/ps6509/prod_release_notes_list.html.

Cisco Phone View—Cisco Unity Connection Phone View allows users to display voice messages on the LCD screen of a Cisco IP phone and to play the voice messages. This feature uses either touchtone keys or voice commands. The criteria that you use to search for messages depends on the conversation version that you are using. For information on setting up Phone View, see the "Setting Up Phone View" chapter of the System Administration Guide for Cisco Unity Connection Release 7.x.

RSS Feeds—As an alternative to checking messages by phone or by using the Cisco Unity Inbox or an IMAP client, users can retrieve voice messages by using an RSS (Really Simple Syndication) reader. When a user marks a message as read, the message is no longer displayed in the RSS reader, but a saved copy is available in the Connection mailbox of the user. For more information on configuring Cisco Unity Connection to supply RSS feeds, see the "Configuring Access to RSS Feeds of Voice Messages" section in the "Messaging" chapter of the System Administration Guide for Cisco Unity Connection Release 7.x.

Mobile Clients

Cisco Unity Connection supports access to voice messages from Windows mobile phones, RIM BlackBerry devices, and Symbian OS phones through Cisco Unified Mobility Advantage and Cisco Unified Mobile Communicator.

For a list of supported mobile clients with Connection Release 7.x with the Cisco Unified Mobile Advantage Release 7.0 and Cisco Unified Mobile Communication Release 3.x and 7.0, see the Compatibility Matrix for Cisco Unified Mobility Advantage and Cisco Unified Mobile Communicator, available at http://www.cisco.com/en/US/products/ps7271/products_device_support_tables_list.html.

Fax Messages

Cisco Unity Connection can integrate with Cisco Fax Server 9.0 or later to support fax messages. Users can send a fax to a fax machine for printing (users can specify the fax number by phone), download a fax from a supported IMAP client, and forward fax messages to other Connection users. For more information, see the "Cisco Fax Server Integration" chapter.

Flexible Administration and Serviceability

See the following sections:

Administrative Tools

End User Web Tools

Administrative Tools

Cisco Unity Connection provides a set of tools for administrating, monitoring, and troubleshooting the system. These tools, some of which are also used by Cisco Unified Communications Manager, are designed to offer a consistent experience and to streamline the ongoing management and operation of the system.

Cisco Unified Serviceability—A monitoring and troubleshooting tool for serviceability that is shared with Cisco Unified Communications Manager. This tool allows you generate reports, enable alarms, set trace information, activate or deactivate services that are generic to the platform, and configure simple network management protocol (SNMP) operations.

Cisco Unity Connection Serviceability—A monitoring and troubleshooting tool for serviceability that is used only by Connection. This tool allows you generate reports, enable alarms, set trace information, manage a Connection cluster, and activate or deactivate services that are specific to Connection.

Real-Time Monitoring Tool—A tool that runs as a client-side application. This tool can monitor system performance, view system error messages, and collect trace log files.

Cisco Unified OS Administration—A tool that you can use to change operating system settings (for example, IP address or NTP servers), view hardware and software configuration information (for example, the amount of memory or the Cisco Unified Communications Operating System version), manage SSL certificates, upgrade Connection and the operating system (they are upgraded together), and enable remote access to the Connection server.

Cisco Unity Connection Administration—A tool used for most administrative tasks, including specifying settings for users and implementing a call management plan. Connection Administration provides access to several other tools including the Bulk Administration Tool, Bulk Edit Utility, Custom Keypad Mapping, Task Management, and tools for importing and migrating user accounts.

Disaster Recovery System—A tool that allows you to back up and, if necessary, restore data and voice messages. For more information, see the "Disaster Recovery" chapter.

For more information about all of the administrative tools, see the "Administrative Tools" chapter of the System Administration Guide for Cisco Unity Connection Release 7.x.

Connection also allows administration tasks to be segmented by administrator roles, so that administrators can be given permission to perform a range of operations from doing individual tasks (for example, resetting passwords or unlocking accounts) to doing all Connection administration functions. For more information, see the "Roles" section in the "Preparing to Add User Accounts" chapter of the User Moves, Adds, and Changes Guide for Cisco Unity Connection Release 7.x.

End User Web Tools

When end users are given access to the browser-based Cisco Personal Communications Assistant (PCA), they can also be granted access to the following web tools:

Cisco Unity Assistant—Allows users to quickly and easily change personal settings such as voicemail options, passwords, personal distribution lists, and message-delivery options.

Cisco Unity Personal Call Transfer Rules—Allows users to create call transfer rules that forward and screen incoming calls based on caller, time of day, or calendar status. (Personal Call Transfer Rules are supported only when Cisco Unity Connection is integrated with Cisco Unified Communications Manager phone systems.)

Cisco Unity Inbox—Allows users to send and access voice messages.

To learn more about these tools, see the applicable User Guide for Cisco Unity Connection Release 7.x and the Help for each tool. Cisco Unity Connection user guides are available at http://www.cisco.com/en/US/products/ps6509/products_user_guide_list.html.

Licensing

Cisco Unity Connection uses license files to enable licensed features. To use a licensed feature, the customer must purchase the applicable license file. A valid Connection license file is required to configure a new Connection system and for adding or changing licensed features. Each license file that a customer purchases uses the MAC address for the network interface card (NIC) in the Connection server, so the license file can be installed only on the server with that MAC address. For information on Connection licenses, see the "Managing Licenses" chapter of the System Administration Guide for Cisco Unity Connection Release 7.x.

LDAP Directory Synchronization and Authentication

If you are using a supported LDAP directory for your corporate directory, Cisco Unity Connection gives you the option to synchronize a small subset of user data in the Connection database with user data in the LDAP directory. In addition, if you configure directory synchronization, you can have Connection authenticate user access to Connection web applications against Active Directory credentials. You can also configure Connection to periodically resynchronize Connection user data with user data in the LDAP directory.

Connection LDAP directory support does not require directory schema extensions, and access to the directory is read-only.

Connection also supports standalone users and users imported from Cisco Unified Communications Manager via AXL. Both standalone users and users imported from Cisco Unified CM can be converted to LDAP users at any time.

For more information on Connection support for LDAP synchronization and authentication, see the "LDAP Directory Integration with Cisco Unity Connection" chapter.

Security

Cisco Unity Connection supports security in a number of areas of the product:

Platform—Connection is based on the Linux-based Cisco Unified Communications Operating System. The operating system is locked down, and no root access is allowed. For more information on the Cisco Unified Communications Operating System, see the Cisco Unified Communications Operating System Administration Guide for Cisco Unity Connection Release 7.x at http://www.cisco.com/en/US/docs/voice_ip_comm/connection/7x/os_administration/guide/7xcucosagx.html.

Call signaling and media stream—Connection allows for authentication and encryption of call signaling and media with both SCCP and SIP trunk integrations with Cisco Unified Communications Manager. For more information, see the "Integrating Cisco Unity Connection with the Phone System" chapter.

Unauthorized access—In order to help prevent unauthorized access, Connection allows for authentication polices (for both phone and web access) that can control the number of attempted logons, account lockout policies, minimum password lengths, and password expiration. For more information, see the "Specifying Password, Logon, and Lockout Policies" chapter of the System Administration Guide for Cisco Unity Connection Release 7.x.

Unauthorized transfers and dial outs—Connection restriction tables control which numbers are allowed for transfers and dialouts, thus locking down unauthorized use of the system by users and helping prevent toll fraud. For more information, see the "Managing Restriction Tables" chapter of the System Administration Guide for Cisco Unity Connection Release 7.x.

Secure messages—Connection supports secure messaging. For more information, see the following "Secure Messages" section.

Communications between Cisco Unity Connection and clients—For more information on securing the communications between Connection and clients, see the "Securing Communications Between Cisco Unity Connection and Clients" section.

Secure Messages

Messages that are marked secure are stored only on the Cisco Unity Connection server, thereby disallowing secure messages from leaving an organization. Users cannot make local copies of secure messages. Message aging policies allow administrators to control how long secure messages are retained before they are archived or permanently deleted.

Secure messages can be played only by using the following interfaces:

Phone

Cisco Unity Inbox

Cisco Unity Connection ViewMail for Microsoft Outlook

Cisco Unified Personal Communicator (CUPC)

Secure messages are streamed securely to these interfaces and do not leave the Connection server. When Connection servers are digital networked to communicate with each other, users on one system can send secure messages to users on another. In that situation, secure messages are encrypted with SMIME while they are in transit between servers.

The following interfaces do not support playback of secure messages:

Third-party IMAP email clients other than Cisco Unity Connection ViewMail for Microsoft Outlook

IBM Lotus Sametime Plug-in

RSS Readers

For more information on secure messages, see the "Securing User Messages: Controlling Access and Distribution" chapter of the System Administration Guide for Cisco Unity Connection Release 7.x.

Securing Communications Between Cisco Unity Connection and Clients

Cisco Personal Communications Assistant—For information on securing the Cisco Personal Communications Assistant (PCA) and Cisco Unity Connection web tools client access to Connection, see the "Securing Cisco PCA and IMAP Email Client Access to Cisco Unity Connection" chapter of the System Administration Guide for Cisco Unity Connection Release 7.x.

IMAP clients—For information on securing IMAP email client access to Connection, see the "Securing Cisco PCA and IMAP Email Client Access to Cisco Unity Connection" chapter of the System Administration Guide for Cisco Unity Connection Release 7.x and the "Configuring an Email Account to Access Cisco Unity Connection Voice Messages" chapter of the User Workstation Setup Guide for Cisco Unity Connection Release 7.x.

Mobile clients—For information on securing communication between mobile clients and Cisco Unity Connection, see the Cisco Unified Mobile Communicator and Cisco Unified Mobility Advantage documentation, available at http://www.cisco.com/en/US/products/ps7271/tsd_products_support_series_home.html.

RSS clients—For information on securing communication between RSS clients and Cisco Unity Connection, see the "Configuring Access to RSS Feeds of Voice Messages" section in the "Messaging" chapter of the System Administration Guide for Cisco Unity Connection Release 7.x.

For a list of servers that are qualified for use with Cisco Unity Connection, including detailed hardware specifications, the maximum number of ports, the maximum number of users, the total number of minutes of message storage, and so on, see the Cisco Unity Connection Supported Platforms List at http://www.cisco.com/en/US/products/ps6509/products_data_sheets_list.html.

Note that when a customer configures a Cisco Unity Connection cluster (active/active high availability), two Connection servers are required:

The publisher server, which publishes the database and message store.

The subscriber server, which subscribes to the database and message store on the publisher server.


Note Both servers can service call traffic and client/administration traffic.


Voice Recognition is also supported on the Connection servers. For capacity planning for voice recognition, see the Cisco Unity Connection Supported Platforms List.

Supported Phone Systems

Revised May 2009

Cisco Unity Connection natively integrates with Cisco Unified Communications Manager and with Cisco Unified Communications Manager Express through Skinny Client Control Protocol (SCCP) or through a SIP trunk.

If the customer integrates Connection with a circuit-switched phone system, additional hardware is needed:

Many integrations with circuit-switched phone systems use PIMG or TIMG units for analog, digital, or T1 interfaces. Serial integrations (SMDI, MCI, and MD-110) with analog interfaces also require special cables. For more information about PIMG/TIMG integrations, see the applicable integration guide at http://www.cisco.com/en/US/products/ps6509/products_installation_and_configuration_guides_list.html.

If the customer integrates Cisco Unity Connection with a QSIG-enabled phone system, an ISR voice gateway is required. For more information, see the applicable integration guide at http://www.cisco.com/en/US/products/ps6509/products_installation_and_configuration_guides_list.html.

Connection can also be integrated with multiple phone systems. For more information, see the Multiple Phone System Integrations Guide for Cisco Unity Connection 7.x at http://www.cisco.com/en/US/docs/voice_ip_comm/connection/7x/integration/misc/guide/cuc7xintmultiple.html.

For the requirements of the phone system integration, see the System Requirements for Cisco Unity Connection Release 7.x at http://www.cisco.com/en/US/docs/voice_ip_comm/connection/7x/requirements/7xcucsysreqs.html.

For more information on phone system integrations, see the "Integrating Cisco Unity Connection with the Phone System" chapter.

For supported deployment models, see the "Cisco Voice Messaging" chapter of the Cisco Unified Communications SRND Based on Cisco Unified Communications Manager 7.x at http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/srnd/7x/vmessage.html.

Cisco Unity Connection Clusters (Active/Active High Availability and Redundancy)

Cisco Unity Connection supports a two-server active/active cluster within a site (LAN) to provide high availability and redundancy. Both servers in the Connection cluster run Connection, and both accept calls, HTTP requests, and IMAP requests. If one server in the Connection cluster becomes inactive, the other server continues to provide the end-user functionality including voice calls, HTTP requests, and IMAP requests. In this situation, a lower port capacity will be available for taking voice calls. For more information, see the "Cisco Unity Connection Clusters (Active/Active High Availability)" chapter.

Digital Networking

Revised July 9, 2009

If you have more users than a single Cisco Unity Connection server or cluster pair allows, you can use Digital Networking to internetwork the systems. With Connection 7.0, you can use Digital Networking to connect up to five Connection servers and/or clusters with a combined total of 50,000 users and/or contacts of all types (system contacts with or without an associated VPIM location and personal contacts). With Connection 7.1 and later, you can connect up to ten servers and/or clusters with a combined total of 50,000 users and contacts of all types.

When Digital Networking is used to network together multiple Connection servers or clusters, users can send, reply to, and forward messages or place calls to any user on any Connection server in the Digital Network. A Digital Network can be configured to allow all users to call the same number from outside the organization to log on regardless of which Connection server they are homed on. The system that answers calls to this number transfers users to the applicable home Connection server to log on.

For more information on Digital Networking design, see the "Networking" chapter.

Third-Party Voicemail Interoperability

Cisco Unity Connection supports Voice Profile for Internet Mail (VPIM) version 2, which allows the exchange of voice and text messages with other messaging systems. You can use VPIM Networking to network Connection with up to ten voice messaging systems, including Cisco Unity, Cisco Unity Connection, Cisco Unity Express, or any third-party voice messaging system that supports the VPIM version 2 protocol.

For more information on VPIM Networking design, see the "Networking" chapter.
