1 System Overview

1.1 Typical Network

Huawei eSpace UMS is developed to communicate with the softswitch using the Session

Initiation Protocol (SIP) to implement voice and fax mailbox functions. In this respect, the

UMS is also called voice and fax mailbox system.

Figure 1-1 shows the typical UMS network, on which the IP private branch exchange (PBX)

and UMS server are two core devices connected through a SIP trunk. The mail server, web

server, and UMS server can ping each other.

The major devices on the UMS network are described as follows:

IP PBX

The IP PBX is a core device of the UMS. As a small-sized next generation network

(NGN) system, the IP PBX provides high-efficiency and high-quality voice services for

enterprise and industrial networks. IP PBX models include eSpace U1910, U1930,

U1960, U1980, U2980, and U2990.

If multiple sub-PBXs are deployed under an IP PBX to use UMS services, you must configure

a unique message leaving prefix and message retrieving prefix for each sub-PBX.

UMS server

The UMS server is the core device for providing the voice and fax mailbox functions. All

voice and fax messages are stored on the UMS server. It notifies users of new voice or

fax messages by sending them message waiting indicator (MWI) notifications, voice

notifications, or emails. Users can then retrieve the voice or fax messages using phones

or fax machines, the UMS web system, or emails.

Mail server

The mail server runs the email service and generally uses the Simple Mail Transfer

Protocol (SMTP) and Post Office Protocol (POP).

Web server

The web server provides the UMS web system that functions as a system management

platform for administrators and a self-service platform for users.

Integrated Access Device (IAD)

As the media access gateway using the Voice over IP (VoIP) technology, the IAD

provides the edge access function based on the IP network. The IAD communicates with

the IP PBX using SIP and implements conversion between SIP and Time Division

Multiplex (TDM) signaling messages, enabling plain old telephone service (POTS)

phones to use VoIP services.

Terminals

Terminals that can use UMS services include SIP terminals (mainly IP phones), fax

machines, and POTS phones.

1.2 Features

eSpace UMS V200R002C00 is a new release with its architecture redesigned based on user

requirements. Compared with earlier versions, eSpace UMS V200R002C00 provides more

comprehensive and stable functions and is more advantageous when it is deployed together

with Huawei IP PBX.

1.2.1 Enhanced Personalization

All users of the UMS can personalize their greetings. Personalized greetings are classified

into three dimensions and three levels. Each user can customize a maximum of 12 types of

personalized greetings. For details, see Configuring Personalized Greetings.




3

1.2.2 Message Classification

Users can set the property of a voice or fax message to urgent, private, or urgent and private.

The UMS processes messages in different ways depending on the message property. Urgent

messages are played preferentially and have the highest priority when being transferred in

emails. Private messages can be listened to or read only by recipients and cannot be

forwarded to prevent leakage.

1.2.3 Automatic Backup and Deletion

Messages of users are automatically backed up to a remote server as scheduled based on

system settings to improve security. The maximum duration and space for storing messages

for each user on the server are limited. The system automatically deletes outdated messages

and the earliest historical messages when the storage space allocated to a user is full,

improving usage efficiency of system resources.

1.2.4 Multi-language Support

The UMS supports interactive voice response (IVR) voice file loading and real-time IVR

language configuration. After voice files are loaded, an administrator or a user can use the

UMS web system to configure the IVR language to be used for the user. In V200R002C00,

the UMS supports the following built-in IVR languages: Chinese, English, Portuguese, and

Spanish. Based on settings of administrators, users can select the default IVR language and

switch between the Chinese and English UI styles for the UMS web system. For details, see

section 2.5 "IVR Language Configuration."

eSpace UMS V200R002C00SPC100 Product Description 2 Service Functions



4

2 Service Functions

The UMS provides voice and fax mailboxes for users to leave, retrieve, and forward messages

in various ways, and uses multiple methods to promptly notify users of new messages.

2.1 Voice Message

Leaving a Voice Message

This function is mainly used to configure the call transfer to voice mailbox unconditional

(CTVMU), call transfer to voice mailbox on no reply (CTVMNR), and call transfer to voice

mailbox on busy (CTVMB) services.

If a user configures the CTVMU service, calls to the user are transferred to the UMS

unconditionally.

If a user configures the CTVMNR service, calls to the user are transferred to the UMS

when the user does not answer calls within a specified period.

If a user configures the CTVMB service, calls to the user are transferred to the UMS

when the user is busy.

In all preceding cases, an announcement is played to prompt calling parties to leave voice

messages.

Users can also customize greetings for the CTVMU, CTVMNR, and CTVMB services. The

UMS first plays the user-defined greetings to calling parties when service conditions are met.

Leaving a Message in an Email

A user can use the mailbox configured for the user's UMS account to leave a voice or fax

message by sending an email to a public mailbox. In the email, the user enters recipients'

UMS accounts, separated with semicolons (;), in the subject field and attaches a WAV or MP3

voice file or an Office/PDF fax file. Then the recipients will receive the attachment in the

email.

Forwarding a Message Using a Phone

This function enables users to forward messages using a phone. When retrieving a non-private

message, a user can forward the message to other UMS users as prompted.




5

Forwarding a Message Using the UMS Web System

When retrieving a message using the UMS web system, a user can forward the message to

other UMS users. The voice and fax messages support the group forwarding function.

Setting the Property of a Voice Message

A voice message can be set to urgent or private. When a user retrieves voice messages, urgent

messages are played preferentially. If multiple urgent voice messages are received, the latest

one is played first. A private voice message cannot be forwarded in any ways.

Configuring Personalized Greetings

In addition to the default IVR greetings, users can customize personalized greetings to be

played to calling parties transferred to the UMS. Personalized greetings are classified based

on the following dimensions:

Operation rights and application scope: personal, organization, and system greetings

Application scenario: temporary, holiday, and status-specific greetings

Call source: internal and external greetings

The UMS automatically plays the greeting with the highest priority.

Leaving a Message in Group Mode

This function enables users to leave a voice or fax message, such as a notice or congratulation,

for multiple users in a batch.
