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.

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."

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.
