uOne Architecture

This chapter will review the architecture of uOne Corporate Edition 4.1E, including the following topics:

• Architectural Goals

• Primary Components

• Corporate Platform

Architectural Goals

The goal of this release of uOne Corporate Edition 4.1E is to provide:

• A messaging solution running all uOne components on a single NT server, with CallManager residing on a separate server

• An Internet Protocol-based messaging system to supply voice messaging services for IP-based telephony services

• Support for standards and off-the-shelf components

• An application that operates as simply another client/server application, running on the same computers, networks, and e-mail messaging systems you are already purchasing, deploying, and maintaining

• Simplified administration that your team is already positioned to support

• Interoperability with other Cisco Messaging solutions, so that you can mix and match messaging solutions and still share the same set of back end servers and data

Primary Components

The following section describes the primary components of uOne illustrated in Figure 2-1.

Figure 2-1: uOne Components

uTel: Telephony Server

The telephony server communicates with CallManager and handles all voice messaging session traffic on behalf of applications.

uPilot: Application Controller

The application controller manages multiple instances of uOne. Every time a call is made, uTel transfers control to an application instance. After the user hangs up, a new instance is started by uPilot.

uLite: Notification Application

This application is responsible for turning the lights on. Whenever a message is left for a user, this application interacts with uTel to turn on the message waiting light (MWI) for the user. When the user listens to all the messages, uOne turns the MWI light off.

Note uOne turns off the MWI light after the user listens to all messages.

uPower: HTTP Web-Based Administration Tools

There are two web-based HTTP administration tools: the uPower/Admin (previously known as Unified Messaging Systems Administration or UMSA) tool, and the uPower/Personal tool for Personal Message Administration.

uPower/Admin is a web-based tool that simplifies systems administration tasks. It is designed to make the complexities of adding information to the Directory Server and Messaging Server seamless.

uPower/Personal is a web-based tool for users to change their personal settings and modify their profiles in the Directory Server. Whenever new users are created, they are given default values for all the parameters. Any changes must be administered by the users via uPower/Personal or over the telephone through User Services.

uOne: Unified Messaging Application

The Unified Messaging application contains the logic to interact with uTel, directory, and messaging servers.

LDAP Directory Server

The LDAP Directory Server stores the uOne User profile data. uOne uses an extension of the LIPS LDAP Object Class. The current version of uOne supports the Netscape Directory Server.

uData: uOne Schema

The schema files necessary for Directory Server to work with uOne are included in this component.

IMAP Messaging Server

The IMAP Messaging Server stores uOne user messages, recorded greetings, and distribution list names.

CallManager

CallManager is a business telephone PBX that uses IP (Internet Protocol) to transmit sound. The CallManager 3.0 software is installed on a separate Windows 2000 system.

Corporate Platform

With the introduction of uOne Corporate Edition 4.1E, the uOne platform of services is structured on a separate system from CallManager. This dual-box platform also prepares both CallManager and uOne for better performance and preparation for future software enhancements. The following diagram shows the different scenarios for Entry and corporate editions.

The first scenario represents the uOne Entry Edition 4.1E utilizing the single-box platform for voice mail. The uOne Entry platform allows the uOne components to reside on the same system as CallManager. This provides a single-box solution for an IP-based messaging system, allowing four to eight uOne sessions on an NT server, along with CallManager, Directory Server, and Messaging Server. This platform was designed to work with the MCS-7830 system, and is designated as the Entry Edition.

In uOne Corporate Edition 4.1E, the uOne platform is configured to run the uOne components on a separate system from CallManager. This dual-box platform uses a MCS-7835 system for uOne, allowing the number of sessions to increase to 20, and the ability to support up to 500 users.

Because uOne Corporate Edition 4.1E automatically configures the MCS-7835 system to use the maximum of 20 sessions, no additional purchases should be made to upgrade the system for additional sessions. The initial purchase of the uOne Corporate Edition 4.1E product includes 20 sessions of uOne and a license for 100 users. Additional user licenses for the uOne product can be purchased in increments of 10.
