Solution Highlights
Huawei EC is user-centric, meaning that it prioritizes user experience. It helps enterprise
customers build an efficient, easy-to-use, and easy-to-manage converged communications
system that features high reliability and mobility, convenient collaboration, strong security,
and easy integration.
2.1 Converged Collaboration Creates More Efficient Office
Converged Omnimedia, Easy to Use

Full-service integration for efficient communication
Huawei EC integrates capabilities including voice, video, IM, presence, group, corporate
directory, web collaboration, and conferencing, allowing users to enjoy these services at
their own convenience, no matter where they are (in the conference room, hotel, office,
or at home).

Clients with intuitive user interfaces and comprehensive functions
Users can easily access Huawei Enterprise Communications applications and switch
between multiple communication modes (messaging, voice calling, video calling, and
multimedia conferencing) using the PC client (Desktop Client) or mobile phone soft
client (Mobile Client). These function-rich terminals deliver consistent user experience
and can help users improve their communication experience and work efficiency.

Portable information for uninterrupted communication
The same account can be used to log in to Desktop Client and Mobile Client at the same
time. Historical messages and contact information are automatically synchronized
between the two, and online messages and offline messages are actively pushed. This
ensures consistent information and uninterrupted communication.

Figure 2-1 Multimedia Convergence for More Efficient In-Conference Collaboration
Integration of HD Voice, Video, and Data for Efficient Collaboration

HD videoconferencing provides a premium communication experience.
Different types of endpoints, including PCs, mobile phones, IP phones, video phones,
and HD video endpoints, can join the same convergent conference, where content can be
easily shared. Enterprise employees in different locations can have face-to-face
communication with each other through convergent conference, which helps enterprises
reduce travel and communication expenses.

Content convergence increases team cooperation.
Sharing documents, PC desktops, whiteboards, or media files in a conference allows
participants to easily obtain key information. Asynchronous document browsing allows
participants to freelyturn pages of a document that the presenter shares. Webbased
collaboration extends team cooperation beyond just one enterprise, enabling its partners
or customers to collaborate and grow with the enterprise.

technologies. These technologies enable the system to dynamically adjust transmission
bandwidth based on the network quality. Even when the packet loss rate reaches 20%,
users can enjoy high-quality voice communication.

48 kHz full-band voice codec, which provides crystal-clear audio performance.

Huawei's full-HD Video Phone 8950, which supports video conferences held on the
server. The IP phone can interact with Desktop Client and Mobile Client, allowing for
efficient video conferences.
Figure 2-3 Huawei's full-HD video phone 8950
2.2 Added Flexibility for Mobile Work Styles
Mobile Client enables users on the move to access office communications applications
conveniently and securely, without compromising information security thanks to data
encryption. With Mobile Client, users can:

Place or answer calls and initiate conferences, saving on call fees and reducing mobile
office costs.

Search the corporate directory for desired contacts and view detailed information and
current status of these contacts.

Share rich media information, including audio clips, video clips, pictures, and doodles.

Join a conference remotely and view content shared on Desktop Client, ensuring that
they do not miss any important conferences.

Description
Call
Admission
Control
If the number of incoming and outgoing VoIP calls is too large, the
network may be congested, therefore affecting voice quality. The system
allows you to limit the number of concurrent incoming and outgoing calls
that are made through SIP trunks to ensure proper use of bandwidth
resources and better voice quality. Then, when the number of concurrent
calls reach the preset upper limit, new incoming and outgoing VoIP calls
will be rejected or routed to other trunks.
Deactivation
of All Services
This feature allows a user to deactivate all the activated supplementary
services. However, the user's service rights are not affected.
Voice Service
Password
Change
The voice service password is used in the outgoing call barring, passwordbased call barring, ONLY, deactivation of all services, and voice mailbox.
It is recommended that the voice service password be changed
periodically to improve the security of voice services.
Busy
Lamp
Field (BLF)
The Busy Lamp Field (BLF) feature allows users to subscribe to the status
(idle, call in progress, ringing, or offline) of others using the
programmable buttons on the IP phone. Before making a call, the calling
party can know the status of the called party. If the called party is not idle,
the calling party waits until the called party becomes idle. This helps
improve the call success rate.
Extension
Mobility
The extension mobility feature allows a user to use the same IP phone
settings in a visited area as in the home area provided that the two areas
belong to the same unified gateway. Since the user logs in to the IP phone
in the visited area using the account of the home area's IP phone, the
account on the IP phone of the home area is logged out.
Service Level
The service level feature enables management of service rights and basic
call rights by service level.
Trunk
Preemption by
User Rights
Level
This feature allows a higher-level user to preempt the trunk of a lowerlevel user to make an outgoing call when the system trunk resources are
insufficient. This ensures the voice service requirements of high-level
users.
Call
Rights
Control
This feature allows the system to determine whether to set up a call
according to the call rights of the calling number and the call type of the
called prefix when a user initiates a voice call. Therefore, call rights can
be flexibly controlled based on actual needs.
Blacklist and
Whitelist Call
Barring
With the blacklist and whitelist call barring feature, calls are accepted or
rejected based on call barring relationships configured in the blacklist and
whitelist.
Passwordbased
Call
Barring
With the password-based call barring feature, users must enter a password
when dialing specific phone numbers, such as a toll call number. The
password-based call barring feature is classified into password-based,
simple-card-number-based, and PIN-Code-based call barring.
Anonymous
Call Rejection
When the system cannot obtain the phone number of a calling party, the
call will be rejected and the called party's phone does not ring.

6.3 Two-Node Cluster and Multi-Node Cluster
EC solution supports two-node clusters for core gateways, some service servers, and some
databases. When the active node in a two-node cluster fails due to a hardware or network
fault, the standby node automatically takes over services. In addition, EC solution supports
clustering of eServers, MAAs, Meeting MSs, UMServers, and recording servers.

The same process is deployed on the active and standby servers to
implement active/standby service processes.
Service
recovery
mechanism
Two servers are deployed in active/standby mode. When one server is
faulty, the other server automatically becomes the active server after
taking over services. When the faulty server recovers, the server
functions as the standby server.
Impact on
services
The active/standby switchover time is less than 5s. The voice calls or
conferences are not interrupted during the switchover.
The active or standby server is not specified. The server that first starts
is the active server. In normal conditions, the active server provides
services. When the active server is faulty, the internal arbitration
process automatically starts the other server to take over the services.
The active and standby servers share the same database and provide
the same signaling IP address for external systems. In this case,
configured or registered services are not impacted.


Two unified gateways are deployed at the headquarters as the
active and standby nodes. The active and standby nodes use a
heartbeat mechanism to constantly check each other's status.
NOTE
The active and standby nodes must use the same unified gateway model.

When the active and standby nodes are running correctly, all users
register with the active node. The active node processes all user
requests and synchronizes user registration and configuration data
to the standby node in real time.

When the active node fails, the standby node takes over all services
from the active node and processes all user requests.

If the trunk gateway is not deployed, the active and standby nodes
both connect to the PSTN. When the active node fails,
configurations are required on the PSTN to set up trunk channels
with the standby node, and the standby node then routes calls to the
PSTN through trunks.

All service servers support active/standby switchover of the
gateways. This means these service servers automatically connect
to the standby node for service processing after a switching from
the active node to the standby node.

mechanism
After switching from the active node to the standby node due to an
active node failure, the standby node processes all services. When
detecting that the active node recovers, the standby node automatically
switches services to the active node.


The switchover lasts about 2 minutes. During the switching, new
calls cannot be initiated. Considering that terminal registration
updates to the standby node, the maximum service interruption
time is 2 minutes plus the duration of terminal registration updates.
The calls that have been set up are not affected.
NOTE
The standby node is allowed to take over services for a maximum of 30 days.
To avoid service unavailability, repair or replace the faulty node promptly.

Issue 01 (2016-06-30)
When the standby node takes over the services, data is not
synchronized to the active node. After services are switched back
to the active node, the active node synchronizes data to the standby
node, and the data on the standby node will be overwritten. Before
manual switchover, export data from the standby node and import
the exported data to the active node so that the data that is
generated on the standby node during the fault period will not be
lost.

On the A-S network, one of the two sites is the primary site and the
other is the backup site.
To register a number, you need to specify the primary and backup
servers (that is, USMs) with which the number will be registered.
On the A-S network, all numbers are registered with one USM. On
the A-A network, two USMs are available for number registration.

Among the three sites (named sites 1, 2, and 3) on the A-A-A
network, each site works as the backup site of another site. Site 2
works as the backup site of site 1, site 3 works as the backup site of
site 2, and site 1 works as the backup site of site 3.
The A-A-S network comprises three sites. Two of them are primary
sites that work in load balancing mode. Another site serves as the
backup site. When either of the primary sites does not work, its
services are automatically switched to the backup site.
To register a number, you need to specify the primary and backup
servers (that is, USMs) with which the number will be registered.
On the A-A-A network, numbers are evenly registered with three
USMs. On the A-A-S network, only two USMs are available for
number registration.
Service Recovery Mechanism for the USM
In the USM disaster recovery scenario, if the active node is faulty, services are automatically
switched to the standby node. When the active node recovers, terminals are re-registered with
the active node after being restarted or arriving at the registration period. In this case, the
active node takes over the services.

Either the two-node cluster in active/standby mode or remote DR can be used for reliability networking
of the unified gateway.
Disaster Recovery Mechanism for the Unified Gateway

Two central nodes are deployed in two places, and each central node has two unified
gateways deployed. The central unified gateways in two central nodes work in
active/standby mode, known as an active node and a standby node (the active and
standby nodes must use the same gateway model). The active and standby nodes use a
heartbeat mechanism to constantly check each other's status. The service servers are
deployed at the central node where the active unified gateway resides.

When the active and standby nodes are running correctly, all users register with the
active node. The active node processes all user requests and synchronizes data to the
standby node in real time. At least 1 Mbit/s bandwidth must be reserved for data
synchronization, and the round trip time (RTT) must be shorter than 80 ms.

When the active node fails, the standby node takes over all services from the active node
and processes all user requests.

A trunk gateway can be deployed for connecting to the PSTN. If the trunk gateway is not
deployed, the active and standby nodes both connect to the PSTN. When the active and

standby nodes are running correctly, the active node routes calls to the PSTN through
trunks. When the active node fails, the standby node routes calls to the PSTN through
trunks.
Service Recovery Mechanism for the Unified Gateway
After switching from the active node to the standby node due to an active node failure, the
standby node processes all services. When the active node recovers, the following two
situations may exist:

Periodic check
By default, the standby node checks the status of the active node at any time. When
detecting that the active node recovers, the standby node automatically switches services
to the active node. In addition, the automatic switching duration (maximum: 255
minutes) can be configured when necessary. If the automatic switching duration is
configured and if the active node recovers after the preset automatic switching duration
expires, the system does not automatically switch services back to the active node.

Daily check
The standby node checks whether the active node recovers at a specific time (default:
02:30:00) every day. When detecting that the active node recovers, the standby node
automatically switches services to the active node.
You can also manually switch services back to the active node when confirming that the
active node recovers.
When the standby node takes over the services, data is not synchronized to the active node.
After services are switched back to the active node, the active node synchronizes data to the
standby node, and the data on the standby node will be overwritten.
Service Impact Due to Unified Gateway Disaster Recovery
The switching lasts about 2 minutes. During the switching, new calls cannot be initiated.
Services are interrupted for at most 4.5 minutes considering the terminals' registration update
interval. Services are still available if the service servers are functional, and the service
servers interact with the standby node.
The switching has the following impacts:

New services cannot be started for ongoing calls, for example, call hold.

Ongoing voice conferences are interrupted.

CDRs cannot be generated for ongoing calls or conferences.

Ongoing message services are interrupted.

Queues in the console system become invalid.

SoftConsole disconnects from the ConsoleServer.
Remote disaster recovery does not support redundancy backup of VMS message data,
recording files, or voice files.

6.5 Local Regeneration
As part of EC solution, the branch nodes (U1911/U1960/U1980/U1981 ) provide local
regeneration functionality to ensure service continuity.
In a network shown in Figure 6-1, all users at the headquarters and branches are registered
with the U1900 series at the central node. The U1900 series at the central node can be
deployed in two-node cluster or remote disaster recovery mode.
If the U1900 series at the central node and the disaster recovery site are both faulty or the
network connectivity is lost between the headquarters and branches, branch users cannot
register with the U1900 series. At that time, the branch nodes can use the local regeneration
function to provide basic telephony services for local IP and analog phone users.
Users' dialing rules remain unchanged, but inter-branch calling using short numbers is
unavailable. To call an internal user at another branch, others can dial the PSTN number of
this user for connecting to this user through the PSTN.

Overview
6 Reliability
When an enterprise branch user (for example, an IP phone user) initiates a call to another
branch user or an external PSTN user, the call request is routed to the branch node. The
branch node then handles the call request and connects the call successfully. The same is true
when an external PSTN user calls an enterprise branch user.
In the local regeneration scenario, CDRs are generated at branch nodes. The CDRServer can
obtain the CDRs from the branch nodes if they are connected.
If an enterprise branch has its own automatic switchboard number, the branch's automatic
switchboard service is available in the local regeneration scenario. If an enterprise has only
one automatic switchboard number, the automatic switchboard service is available only at the
node to which the automatic switchboard number belongs.

Intranet Access Security

IP phones are authenticated using 802.1x.

UC soft terminals (Desktop client and mobile client) comply with the intranet access

Extranet Access Security
An enterprise network is divided into two parts: demilitarized zone (DMZ) and enterprise
intranet. These two parts belong to different network segments, between which an intranet
firewall is deployed to isolate the two parts using network address translation (NAT). An
extranet firewall is deployed at the edge of the enterprise network, and all terminals can
access the DMZ only through this firewall. The session border controller (SBC) bridges the
enterprise extranet and DMZ. It implements NAT traversal with the assistance of the extranet
firewall. The communications data is encrypted before being transmitted over the public
network. Encrypted transmission ensures data security.
The EC supports access of desktop client, mobile client, web conference clients, and
telepresence terminals from an extranet. For details about the access network, see 4

7.2 Communication Service Security
In EC solution, service data, including voice, message, and video, is transmitted over a
relatively open IP network. To avoid security issues, EC solution provides multiple service
security management mechanisms.
End-to-End Signaling and Media Encryption

EC solution supports TLS-based encryption of signaling streams exchanged between
terminal and servers, between terminals and call management device, between servers,
and between servers and call management device.

EC solution supports SRTP-based encryption of media streams to ensure the
transmission security of voice and data.

The signaling and media streams of the Meeting MS use the AES256 encryption
algorithm, the key exchange algorithm uses the RSA 2048 or a later version, and the
digest algorithm uses the SHA256 or a later version.

The password for an desktop client and mobile client logging in to the eServer must be
stored via the SHA256 irreversible encryption algorithm.

Data such as the directory and personal information is encrypted via AES256 before
storage.
Service Interface Authentication
EC solution provides comprehensive management interface security policies. The security
management protocols based on strong authentication and encryption ensure confidentiality
and integrity of management channels. EC solution also provides insecure protocols for
customers to use in trusted networks, ensuring the flexibility of security mechanisms.
Passwords are required before users invoke some interfaces between terminals and servers,
between servers, or for accessing the BMU and USM web through web browsers.
The USM provides the whitelist function. If the IP address of a server is not in the IP address
whitelist of the USM, the server cannot access the USM. This ensures access security of core
servers.
Encrypted Storage and Transmission of Sensitive Data

The access passwords used between terminals and servers and between servers are
encrypted for storage.

The passwords used for authentication between terminals and servers and between
servers are encrypted for storage.

The passwords used for joining data conferences are encrypted for storage.

The access passwords used between terminals and servers and between servers are


Interfaces between the BMU or USM and web browsers and between the BMU and
conference clients support HTTPS.

Interfaces between the BMU and AD server support LDAPS.

are allowed to access the database or configuration file.
Digital Certificate Security

Strong passwords are used for encrypting and decrypting private key files of the digital
certificate. The passwords are encrypted for storage.

EC solution supports replacement of digital certificates. Enterprises can customize their
passwords, apply for certificates from certificate authorities, and replace the default
system certificates.
The following interfaces use digital certificates for authentication:

Web interface for a web browser to access the BMU and USM

Interface for a conference client to access the Meeting MS

Interface for a SoftConsole to access the ConsoleServer
Service Rights Control
EC solution can control call service rights on a per-user basis. Users' call rights can be
configured based on their business scopes to avoid issues such as toll fraud and protect
enterprise benefits.
Toll Fraud Prevention
Toll fraud is a severe communication security issue facing enterprises. The following toll
fraud scenarios may exist:

Someone may illegally obtain the administrator's account and password, and modify the
service configuration and disable the CDR using the administrator's account and
password obtained. Then, he or she can place toll calls.

Someone can connect to a toll call number through the enterprise's automatic
switchboard.

An international toll call can be connected by routing the call from the enterprise's local
gateway to the enterprise's international gateway.

Someone who is not an enterprise's employee may illegally obtain an employee account
and register with the enterprise's internal voice gateway to place toll calls.
EC solution provides comprehensive security mechanisms to effectively prevent toll fraud in
the preceding scenarios.

The core gateways and servers are deployed on the enterprise intranet and isolated from
the public network.

The core gateways and servers are hardened, and unused ports and accounts are disabled.
The two measures combine to mitigate the risks of system attacks.

Complex passwords are supported. It is recommended that strong passwords be used for
the administrator accounts and other key accounts, and such passwords be changed
periodically to reduce the risks of obtaining accounts and passwords in an unauthorized
manner.


Multiple rights control approaches are used to reduce the toll fraud risks. The approaches
include controlling outgoing calls from the automatic switchboard, controlling outgoing
calls routed through trunks, controlling user service rights, and limiting the duration and
concurrence of toll calls.

Users can be authenticated by IP address, password, IP address+password, or IP address
segment to prevent unauthorized user registration.

Whitelists and blacklists for management IP addresses can be configured. If the IP
address of a maintenance terminal is not whitelisted, users cannot log in to
U1911/U1960/U1980/U1981 through this maintenance terminal.

The CDR server is provided for recording CDRs in real time. The recorded CDRs ensure
traceable information in case of toll fraud.
Directory Access Rights Control
The administrator can classify employees into different levels and configure directory access
policies for users of different levels.
Sensitive Word Filter
EC solution supports filtering of sensitive words. If an IM carries sensitive words defined in
the system, the sensitive words are displayed as asterisks (*) at the Rx end. The administrator
can set the sensitive words.
IM and File Transfer Security

The maximum characters that an IM contains can be limited.
The text to send can contain a maximum of 1000 characters (including emoticons, each
of which takes up 3 characters). The content (including pictures) to send in each IM
cannot exceed 2.5 MB.

EC solution supports an independent management plane, which separates management
data from service data.
−
The management data and service data generated during interaction between the
BMU and terminals are transmitted through different ports.
−
U1911/U1960/U1980/U1981 support separation of management network ports from
service data network ports.

Maintenance terminals access the servers or U1911/U1960/U1980/U1981 through SSH.

Comprehensive management protocols are used.
−
The BIN channel between the BMU and the USM, BMU and the
U1911/U1960/U1980/U1981 is encrypted using TLS for transmission.
−
HTTPS is used for web management.
−
FTPS is used for file upload and download.
−
eSight uses SNMPv3 for managing service NEs and uses TR069 over SSL for
managing IP phones. The management channel between eSight and
U1911/U1960/U1980/U1981 runs SSH.

EC solution supports authentication based on strong passwords, and the default
passwords are strong passwords, too. This approach effectively prevents brute-force
attacks.

can be deployed in the existing network management zone of the enterprise. Refer to the
Communication Matrix document to configure firewall policies. Ensure that on the firewalls
deployed at the egress of the server zone, only necessary service ports are opened to UC
terminals and only necessary management ports are opened to O&M terminals. Ensure that
ports used for interactions between servers (for example ports used by UC applications to
access databases) are disabled on firewalls.

Management and Maintenance
The EC solution provides eSight, Business Management Unit (BMU), and Local Maintenance
Terminal (LMT) to help users perform O&M tasks efficiently.
9.1 Centralized NE Monitoring
eSight centrally monitors NEs by managing their performance and alarms.
Topology Management
eSight provides a network topology to present NEs and their connections. With the help of the
network topology, users can understand the hierarchical structure and running status of all
NEs across the network. When a new NE is created, eSight automatically discovers and adds
it to the network topology. Alternatively, users can manually search for new NEs and add
them to the network topology.
Resource Management
eSight manages NEs by subnet. According to the physical locations of the devices, the
administrators can put the devices into different subnets for management.
Performance Management
eSight collects the performance data of managed NEs and displays it in charts. By reading
these charts, users can understand potential network risks and take preventative measures
accordingly.
eSight displays monitoring results in bar charts or line charts to clearly show the performance
trends. The administrators can eliminate potential risks by taking active measures before a
performance counter reaches its threshold.
Alarm Management
eSight monitors network alarms in topology views, alarm panels, and alarm bar charts. It
monitors network exceptions in real time so that the administrators can take measures against
the detected network exceptions in a timely manner to restore network operation. The
administrators can set remote notification rules, masking rules, and tones for alarms based on
the site requirements, which optimizes network management.
Issue 01 (2016-06-30)
95
Overview
Once eSight detects an alarm, the administrators can review alarm details, acknowledge the
alarm, locate the alarm, and then clear the alarm.
Configuration Management
eSight allows the administrators to remotely configure specific devices.
Device Panel Management
eSight provides an intuitive device simulation GUI (also known as device panel) for
U1911/U1960/U1980/U1981, where the administrators can view board and indicator status.
Maintenance Management
eSight supports batch upgrade of IADs and IP phones, which is useful when a large number of
devices need to be upgraded.
