Setting the Conference Parameters

Answer mode

Specifies how your endpoint handles incoming calls.

• Manual: You need to manually answer incoming calls.

• Auto: The endpoint automatically answers incoming calls.

Mute local audio for answered calls

Specifies whether the endpoint turns off all sounds generated at your site when the endpoint joins a conference. If you enable this function, no remote participants can hear you.

This parameter is available only when Answer mode is set to Auto.

Enable do not disturb

Specifies whether the Do Not Disturb (DND) function can be enabled from the user interface.

Default call bandwidth

Specifies the default bandwidth at which the endpoint initiates calls.

Maximum incoming call bandwidth

Specifies the maximum bandwidth for incoming calls.

Call settings

Specifies whether call parameters can be set for calls initiated using the remote control.

• Enable: You can set call parameters, such as the call type and call bandwidth, when you place a call using the remote control.
• Disable: You cannot set call parameters when using the remote control to initiate a call.

Wi-Fi network preferred

Specifies whether the endpoint places calls using its IP address on the Wi-Fi network or LAN.

• Enable: When Wi-Fi and other networks are available at the same time, use an IP address on the Wi-Fi network with priority to place a call.
• Disable: When Wi-Fi and other networks are available at the same time, the network port IP address is used to place a call.

Allows IP calls

Specifies whether the endpoint can call a remote site by IP address.

Allow H.323 incoming calls

Specifies whether the endpoint allows remote sites to call its H.323 number. After this function is disabled, a remote site is notified that the called endpoint is busy when failing to call the endpoint's H.323 number.

Unified access number

Specifies the prefix that will be uniformly added to each number dialed by the endpoint. For example, 0755 is specified as the Unified access number. If the number to dial is 07556999, you only need to enter 6999. Then 0755 will be automatically prefixed to 6999.

Recording server address

Specifies the IP address or URL of the Recording & Streaming Engine (RSE).

Background image

Specifies whether to enable the function of allowing you to join a conference by scanning a QR code from the WeLink client and the function of prompting you that the endpoint is not in any conferences (namely, in idle state).

• QR code - cloud platform: Select this option if your endpoint is located on a Huawei cloud. After the endpoint stays in idle state for 15s, the screen connected to the endpoint automatically displays the UI where you can join a conference by scanning a QR code through WeLink or CloudLink SoftClient. Alternatively, you can press the Back button until this UI appears.

  This UI consists of a background image and a QR code. The QR code is generated based on the value of Scanning device address and the SIP or H.323 number registered for the endpoint.

• QR code - intranet: This function is available only when Scanning device address is specified for the endpoint and the E.164 number is configured for the endpoint when it registers with the GK. After the endpoint stays in idle state for 15s, the screen connected to the endpoint automatically displays the UI where you can join a conference by scanning a QR code. Alternatively, you can press the Back button until this UI appears.‏

  This UI consists of a background image and a QR code. The QR code is generated based on the value of Scanning device address and the E.164 number mentioned above.

• Idle state: After the endpoint stays in idle state for 15s, the screen connected to the endpoint automatically displays the UI that prompts you the endpoint is idle state. Alternatively, you can press the Back button until this UI appears.
• Disable: Both functions described above are disabled.

The background image on the UI where you can join a conference by scanning a QR code and the image on the UI that prompts you the endpoint is idle state are shared, which can be replaced using the upgrade tool.

Scanning device address

This parameter is available when Background image is set to QR code - intranet or QR code - cloud platform.

• When Background image is set to QR code - intranet, set this parameter to the IP address of the WeLink server.
• When Background image is set to QR code - cloud platform, this parameter value is automatically provisioned by the eSight server.

Create Conference

Specifies whether to provide the Create Conference function on the Conference Schedules screen on the endpoint's user interface.

Q.931 keepalive

Specifies whether to enable the Q931 keep-alive function to keep alive links between the Huawei endpoint and devices of other vendors. If this function is disabled, calls between the Huawei endpoint and devices of other vendors may be released abnormally.

Audio protocol

Specifies the protocol that the endpoint uses to encode and decode audio.

Video protocol

Specifies the protocol that the endpoint uses to encode and decode video. In a single-streaming conference, the video protocol of the endpoint is used.

Video resolution

Specifies the video format. The available options vary depending on your settings of Video protocol.

When Video protocol is set to Auto, set this parameter to either of the following:

• Sharp: The endpoint uses a high video resolution to ensure clear video.
• Smooth: The endpoint uses a high frame rate to ensure smooth video.

Video frame rate

Select a frame rate based on the specified video resolution.

Prevent little packet loss

This function is designed for the conference environment that has few packet losses and sound network conditions. This function is disabled by default.

If artifacts occur in a conference, you can enable this function to improve the video quality.

Generally, disable this function.

Presentation

Specifies whether you can share presentations during conferences.

Presentation protocol

Specifies the protocol that the endpoint uses to encode and decode presentations.

The available options vary depending on your settings of Video protocol.

Presentation resolution

Select a resolution based on the presentation protocol.

If Presentation protocol is set to Auto, Presentation resolution has only one option, that is, Sharp.

Presentation bandwidth setting

Specifies the mode for setting the presentation bandwidth. The options are as follows:

• Auto: Your endpoint automatically sets the presentation bandwidth based on the bandwidth available.
• Manual: You must manually set Presentation bandwidth.

Presentation bandwidth (%)

Specifies the call bandwidth percentage occupied by the presentation. This parameter is available only after Presentation bandwidth setting is set to Manual.

The default value is 50.

Video interconnection mode

Specifies the mode in which the local endpoint exchanges video streams with the remote endpoint through H.264 BP.

• Auto: The local endpoint automatically identifies the model of the remote endpoint and sets the interconnection mode.
• Compatible: The local endpoint fails to automatically identify the remote endpoint so its video is unavailable on the remote endpoint. Select this option if the peer endpoint is a Huawei's ViewPoint 9039, ViewPoint 9039M, ViewPoint 9035, or ViewPoint 9036, Cisco's CTS500 or Vidyo, or Polycom's QDX 6000, VSX 7000, or VVX 1500.

SiteCall networking mode

Specifies the networking mode used when an endpoint initiates a multipoint call.

• SMC: Use the on-premises network for a SiteCall.
• MediaX: Use the MediaX network for a SiteCall.
• Auto: Preferentially use the on-premises network for a SiteCall. If the SiteCall fails, use the MediaX network for a SiteCall.

Conference line type

Specifies the protocol used by the endpoint to initiate multipoint conferences in the SMC-based networking scheme.

This parameter is available only when SiteCall networking mode is set to SMC.

Preferred IP protocol

Specifies the protocol that IP sites preferentially use. The options are as follows:

• H.323: The H.323 protocol is preferentially used to place IP calls.
• SIP: The SIP protocol is preferentially used to place IP calls.

H.323 URI call mode

Specifies the mode in which the endpoint places calls by domain name. The options are as follows:

• H.323 URI prefix call: Calls are placed using the domain name prefix. Select this option if the endpoint is not registered with the GK and wants to join an ongoing conference on the MCU.
• H.323 URI call: Calls are placed using the full domain name.

Reserved presentation bandwidth

Specifies whether the endpoint reserves bandwidth for presentation sharing when no presentation is being shared. The options are as follows:

• Enable: The endpoint reserves certain bandwidth for presentation sharing even though no presentation is being shared.
• Disable: The endpoint does not reserve bandwidth for presentation sharing and uses all the bandwidth for video and audio.

Dynamic bandwidth

Specifies whether the endpoint implements the following if audio and video quality decreases (such as increasing packet loss rate and network latency) arepredictable due to insufficient network bandwidth: automatically decreases the conference bandwidth until packet loss does not occur constantly or the conference bandwidth is decreased to 64 kbit/s. If constant packet loss is detected, the endpoint can dynamically adjust bandwidth to recover stable conference quality within 1 minute.

• When the network is running within normal parameters, select Disable.
• When the network is not running within normal parameters, select Enable.

Resolution reduction at low bandwidth

This parameter is available only after Dynamic bandwidth is set to Enable.

After Resolution reduction at low bandwidth is set to Enable, if the video protocol used by the endpoint is H.264 HP and the call bandwidth is 384 kbit/s, the endpoint uses 720p 30 fps for video encoding. If the same video protocol is used, but the call bandwidth increases to 512 kbit/s, video is encoded at 1080p 30 fps.

SIP keep-alive period (s)

Specifies the interval at which the local endpoint periodically sends SIP link keepalive packets to the remote endpoint.

BFCP keep-alive period (s)

Specifies the interval at which the local endpoint periodically sends BFCP link keepalive packets to the remote endpoint.

AES256 encryption

Specifies whether to use the AES-256 encryption algorithm for encryption when the endpoint initiates an encrypted conference.

Interworking with Polycom

After this function is enabled, the endpoint:

• Connects to the Polycom recording server.
• Saves layout settings locally.
