5.3 P2P to MultipointWhen the endpoint is connected to an MCU, you can turn a P2P call into a multipoint call,increasing conference efficiency. Below are different scenarios where this may be necessary.

Local Site Receiving Calls from Other Sites

If two sites are having a P2P call and one of the sites receives another incoming call (ormultiple incoming calls), that site can perform one of the following operations:

l Answer&Merge: Answer calls from other sites and turn the P2P call into a multipointconference.

l Answer&Hold: Answer calls from other sites and place the original P2P call.l Answer&Release: Answer calls from other sites and release the original P2P call.l Ignore: Ignore calls from other sites, close the incoming call notification dialog box, and

continue the original P2P call.l Reject: Reject calls from other sites and continue the original P2P call.



20

Local Site Placing Calls to Other Sites

If two sites are having a P2P call and one of the sites calls another site (or multiple sites), thatsite can perform one of the following operations:

l Hold&Call: Place the original P2P call on hold and place a call to another site or toseveral other sites.

l Merge: Place the original P2P call on hold, and place a call to another site or to severalother sites, and turn the P2P call into a multipoint conference.

l Add: Add sites to the original P2P call to turn it into a multipoint conference.

l Cancel: Cancel calling another site or several other sites and continue the original P2Pcall.

Call Hold

In call hold state, the local and remote sites cannot hear or video each other. They can do thisonly after the call hold operation is canceled.

If two sites are having a P2P call and one of the sites receives another incoming call, that sitecan perform one of the following operations:

l Answer&Hold: Answer the incoming call and place the original P2P call on hold.

l Answer&Release: Answer the incoming call and release the original P2P call.

l Ignore: Ignore the incoming call, close the incoming call notification dialog box, andcontinue the original P2P call.

l Reject: Reject the incoming call and continue the original P2P call.

The site in an active call can be placed on hold or released, and the site on hold can beresumed off hold or released.

5.4 Registering with the SC Using the Same SIP Numberas the Soft Client

When a TE30 registers with an SC through H.323 or SIP, its soft client can register with thesame SC through SIP using the same number. However, once the soft client is registeredsuccessfully, the TE30 will be deregistered.

5.5 Conference Control from the Web Interface

Conference control enables a more flexible and functional conference system. Conferencecontrol can be performed by the chair or by the non-chair site. The chair site can perform adiverse range of practical conference control operations, while the non-chair site can performsome simple conference control operations. For the TE30 that joins a conference initiated bythe Videxio platform, conference control functions are unavailable.

Figure 5-3 shows the conference control operations that the chair site can perform.

5.6 Network Address Book

The network address book stores the information about sites in the videoconferencing system.The administrator can download the address book and update the entries in batches. Networkaddress books can be stored on an FTP or Lightweight Directory Access Protocol (LDAP)server.

l If network address books are stored on an FTP server, the endpoint automaticallydownloads and synchronizes site information from the FTP server when powering on.The administrator can also manually download or update the address book.

l If network address books are stored on an LDAP server, the endpoint searches the LDAPserver for site information, and adds the site information to its local address book. Youcan specify whether to replace the site information in the local address book if the siteinformation on the LDAP server is the same as the information in the local address book.

5.7 Conference Recording

The RSE server can record conferences, including local conferences, conferences initiatedusing the built-in MCU, and conferences initiated using a standalone MCU. Explanations ofconference recording in different scenarios are given below.

l Local conference

The RSE server's IP address is set on the endpoint, and neither the endpoint or the RSEserver needs to be registered with a GK server.

l Multipoint conference hosted by SMC2.0

An SMC2.0 uniformly allocates RSE resources. The SMC2.0 sends RSE siteinformation to the MCU, and the MCU adds the specified RSE to the conference toenable recording. Operations such as starting conference recording and configuring theRSE server can be performed on the SMC2.0. The SMC2.0 also supports automaticconference recording and automatic activation of the conference recording function.



22

l Multipoint conference directly initiated from the endpointThe endpoint and RSE server need to be registered with a GK server. The URL or IPaddress of the RSE server needs to be configured on the endpoint. During a multipointconference, the chair site and the site where the built-in MCU is used can performrecording operations.

l Multipoint conference hosted by a built-in MCUConferences are recorded by the RSE server without the participation of the MCU.Neither the endpoint or RSE server needs to be registered with a GK server. Theendpoint adds the RSE server to the conference by calling the IP address of the RSEserver, after which the RSE server allocates recording resources and completes therecording task. This mode is simple, flexible, and convenient.

5.8 Wi-Fi Connectivity

The endpoint has a built-in Wi-Fi module and is able to function as a Wi-Fi client, a Wi-Fiserver, or both simultaneously. The maximum bandwidth is 54 Mbit/s and the frequency is 2.4GHz.

If the endpoint has the Wi-Fi client function enabled, it automatically detects and connects toWi-Fi servers. You can set the endpoint IP address in DHCP or static mode. If a wirednetwork deployment is not suitable, the endpoint can connect to the Internet through awireless router. Therefore, the Wi-Fi client can be enabled when wired networks areunavailable and the endpoint needs to access networks through wireless routers.

If the endpoint has the Wi-Fi server function enabled, it can connect to a VPM220W(Huawei's wireless microphone array) through Wi-Fi, eliminating the need for physicalconnections.

If a user also purchases a wireless microphone or touch panel, the user can connect it to anendpoint through Wi-Fi to control the product.

Figure 5-4 shows the Wi-Fi network.

Network Layer SecurityFigure 5-9 shows the endpoint security networking.



29

Figure 5-9 Security networking

On this network, the endpoint is connected to the Multipoint Control Unit (MCU) through theprivate network. The MCU connects to different networks through different ports. Theendpoint on the private or public network can join conferences even if the H.323 protocol orthe firewall settings (such as enabled ports) are not changed.

Firewall Technology (NAT)The firewall protects your IP network by separating the internal and external networkcommunication data. Using Network Address Translation (NAT) technology and exchangingsignaling between public network protocols and private network protocols, the firewallenables sites on local area networks (LANs) in different places to enjoy the convenience ofcommunication through video conferences. With NAT, a device on an LAN is allocated adedicated internal IP address that uniquely identifies the device on the LAN, and the deviceuses an external IP address to communicate with external devices. Through NAT mapping,



30

multiple internal IP addresses are mapped to one external IP address. NAT mapping not onlyreduces the number of IP addresses that are needed for users on a private network to accessthe Internet, but also enhances the security of the private network.

Network Diagnostics

Network diagnostic tools are provided to ensure correct network settings and proper networkperformance indicators, such as routing information, port filtering policies on the firewall,network delay, packet loss rate, ratio of incorrectly sequenced packets, jitter, types of NATdevices, and modification of H.323 and SIP messages by the application level gateway(ALG). Network diagnostic tools provide users with easy-to-use professional networkdiagnostic services, helping them rectify network faults quickly.

When a web-based diagnostic tool is used to connect to the endpoint, the user must enter theuser name and password, which are encrypted and then transmitted to the endpoint.

Web Request Authenticationl When a user requests access to a specified web page or submits a servlet request, the

endpoint checks whether the user's session identifier is valid and whether the user isauthorized to perform the operation.

l The server implements the final authentication on the user.

l Before transmitting user-generated data to clients, the server verifies the data andencodes it using HyperText Markup Language (HTML) to prevent malicious code andcross-site scripting attacks.

l Web security software is used to scan the web server and applications to ensure that thereare no high-risk vulnerabilities.

Protocol Anti-Attack Measuresl The communication port matrix is provided in the product documentation. Services and

ports not mentioned in the communication port matrix must not be enabled.

The communication port matrix contains the following information: open ports, transportlayer protocols used by the ports, network elements (NEs) that use the ports tocommunicate with peer NEs, application layer protocols used by the ports anddescription of the services at the application layer, whether services at the applicationlayer can be disabled, authentication modes adopted by the ports, and port functions(such as data traffic control).

l The Real-time Transport Protocol (RTP) and Transport Layer Security (TLS) are used toencrypt media streams and signaling of voice services respectively, ensuring securecommunication between users.

l For network management, the endpoint supports the Simple Network ManagementProtocol v3 (SNMP v3), which features higher adaptability and security. User names areneeded to connect the network management system to the endpoint.

l Robustness testing tools are used to scan protocols to ensure that there are no high-riskvulnerabilities.

l By default, the File Transfer Protocol over SSL (FTPS) and LDAP over SSL (LDAPS)are used to encrypt the address book, ensuring data integrity and preventing data frombeing stolen.



31

Protection of Sensitive Datal To prevent sensitive data from being disclosed, the endpoint checks the complexity of

the default password and user-defined passwords. A password is displayed as "." or "*"when entered in the password input box, and the entered password cannot be copied.

l No proprietary encryption algorithms are used.

System Management and Maintenance Securityl Software packages (including patches) are released only after they are scanned by at

least one type of mainstream antivirus software and no alarm is generated. Explanationsare provided for alarms under special circumstances.

l All user operations and system abnormalities are recorded into logs.
