The uOne Application

The uOne application agent is built on the Distributed Agent Platform and, as a genuine DAP agent, inherits the benefits of the middleware platform, including scalability, availability, and manageability.

The uOne application is designed to be modular (Figure 4), thereby providing customers the flexibility of bundling services as required to meet market demands. The service can be configured for voice messaging only, or voice messaging combined with any of the other services, such as fax messaging , e-mail, and notification. Please note that from a telephony access perspective, voice messaging is the core service and is always enabled. From a PC access perspective, e-mail is the core service and is always enabled.

Figure 4: Modular Design of uOne

The key services for uOne include voice mail, fax mail, e-mail, outbound calling services, single number reach, and notification services. These services can be accessed from both the telephone and PC, as well as other thin client Internet phones. See "uOne 4.2s Features" for details about features.

Overview of uOne Components

This section briefly describes the components that overlay a standard Internet Messaging Environment and work in conjunction with the VoIP H.323 network infrastructure. Figure 5 and Table 5 show the components that apply to the Telephone Access of the service. Figure 6 and Table 6 show the components that apply to the PC Access of the service. Any of the components that were previously discussed will not be covered again in this section.

Component Description

UM

Handles incoming voice calls from subscribers and non-subscribers. It allows the user to access, send, forward, and reply to messages, make calls, and provision options.

FaxPrint

If fax services are enabled, the FaxPrint application allows subscribers to send fax messages from their mailbox to a fax machine or a fax mailbox.

LogRemover

Periodically purges or moves log files from the Gateserver according to a configurable set of rules.

MWI_OnOff

Receives new message indications from MWI_Notify and acts on subscriber preferences to turn on the Message Waiting Indicators (such as MWI lights on a telephone and stutter dial tone) or send a notification page.

MWI_Notify

Receives new message indications from MWI_PassOff via a TCP connection and sends these indications via LACS to MWI_OnOff .

MWI_PlugIn.so

Generates new message indications for e-mail, voice, and fax messages and sends them to MWI_PassOff via a FIFO.

MWI_PassOff

Receives new message indications for e-mail, voice, and fax messages from the MWI_PlugIn.so library via a FIFO and sends these indications to MWI_Notify via a TCP connection.

SMS_Notify

Sends SMS notification messages to subscriber's cellular telephones. It checks the SMS_Notify mailbox for messages needing notification and contacts a Short Message Service Center via SMTP or SMPP.

notify.so

Adds the SMS_Notify mailbox to the recipient list for each incoming voice, fax or e-mail message.

Deployment Scenarios

The modular design of DAP and the uOne application allows maximum flexibility in distributed deployment scenarios. Depending on the business need, the service can be deployed completely centralized, completely distributed, or a hybrid hub and spoke scenario.

In a decentralized solution, Service Providers can provide local call access. Local call access is the ability to dial into the closest Gateserver to access subscriber services. For example, subscribers who normally work in New York City would dial from their telephones the local 212 access number to get their messages. When they are visiting San Francisco, they would dial the local 415 access number to get their messages. The messages would be pulled across the IP infrastructure, perhaps from a messaging server in New York. This is similar to how PCs access their Internet Service Provider or online services, such as America Online.

Figure 7 illustrates a centralized set of backend servers with distributed VoIP telephony access. GateWays are generally deployed at the points of presence and provide local call access and subsequent conversion to H.323 for access to uOne services over an IP network.
