  1. Choose System Settings > Conference and click the Advanced Settings tab.
  2. Set the advanced conference parameters listed in Table 1-20.

    Table 1-20  Advanced conference parameters

    Parameter

    Description

    Setting

    Audio protocol

    Specifies the audio and video protocols supported by the endpoint. Using the audio or video protocol that you select, your endpoint negotiates the audio or video capability with a remote endpoint to set up a call.

    Select a value from the drop-down list box, where only the audio protocols selected for Audio and Video Protocols beforehand are available. If Auto is selected, the endpoint will automatically select an audio protocol to ensure clear and smooth audio.

    The default value is Auto.

    The default value is recommended.

    Audio channels

    Specifies the audio channels.

    This parameter is available when Audio protocol is set to AAC-LD.

    The default value is Two.

    Video protocol

    Specifies the video protocol your endpoint uses to encode video.

    During a non-multi-stream conference, the video protocol is the video protocol the endpoint uses at your site.

    The default value is Auto.

    To initiate an HD video conference, select an H.265 video protocol.

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

    The default value is Sharp.

    Video frame rate

    Specifies the frame rate used during video encoding.

    Video at a higher frame rate is smoother. Video at a lower frame rate is clearer.

    When Video protocol is set to Auto, this parameter is not available.

    The default value is Auto.

    It is recommended that you set this parameter to Auto.

    Prevent small packet loss

    Specifies whether to prevent sporadic packet loss to avoid artifacts.

    The default value is Disable.

    Select this parameter if all endpoints are on the same private network and sporadic packet loss occurs.

    Presentation

    Specifies whether you can share presentations during conferences.

    NOTE:

    You can set Presentation protocol, Presentation policy, Presentation resolution, Presentation bandwidth setting, and Presentation plug-and-share only after you set this parameter to Enable.

    The default value is Enable.

    Presentation protocol

    Specifies the video protocol your endpoint uses to encode presentations.

    The default value is Auto.

    Presentation policy

    Specifies the endpoint's wired projection and browser sharing policy when the endpoint joins a data conference.
    • Auto: When the endpoint supports collaboration, data sharing is used. If the endpoint does not support collaboration, presentation sharing is used.
    • Presentation source prioritized: Presentation sharing is prioritized. If the endpoint does not have the presentation capability, data sharing is used.
    • Data prioritized: Data sharing is prioritized. If the endpoint does not support collaboration, presentation sharing is used.

    The default value is Auto.

    Presentation resolution

    Specifies the presentation format. The available options vary depending on your settings of Presentation protocol.

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

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

    The default value is Sharp.

    Presentation bandwidth setting

    Specifies the mode for setting the presentation video bandwidth.

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

    The default value is Auto.

    Presentation bandwidth (%)

    Specifies the percentage of the call bandwidth presentations can occupy.

    NOTE:

    This parameter is available only when Presentation is set to Enable and 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: Your endpoint automatically identifies the model of the peer endpoint and sets the mode for interconnecting with the peer endpoint.
    • Compatible: The local endpoint fails to automatically identify the peer endpoint so its video is unavailable on the peer 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.

    The default value is Auto.

    Networking mode

    Specifies the type of the NE that interacts with the endpoint.
    • SMC: Select this option for the on-premises network.
    • uPortal: Select this option for the non-on-premises network where data conferencing is required.
    • MediaX: Select this option for the non-on-premises network where data conferencing is not required.

    Contact the network administrator.

    The default value is SMC.

    SMC address for data conferencing

    Specifies the SMC server address. In the SMC network, the endpoint does not activate the cloud platform SMC. When the endpoint needs to use a standalone SC and supports data conferences, you need to set the SMC server address.

    This parameter is available only when Networking mode is set to SMC.

    No default value is set for this parameter.

    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 Networking mode is set to SMC or uPortal.

    The default value is Auto.

    Preferred IP protocol

    Specifies the protocol that IP sites preferentially use.

    NOTE:

    When Line type is set to Auto for IP sites, your endpoint uses this protocol to call the IP sites. When you choose Conference > Call and start a conference on the call page, you can set Line type of IP sites.

    The default value is SIP.

    H.323 URI call mode

    Specifies the mode in which the endpoint places calls by domain name.
    • 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.

    The default value is H.323 URI call.

    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 videos and audio.

    The default value is Enable.

    Secondary dial mode

    Specifies the secondary dial node.

    The default value is Auto.

    Presentation plug-and-share

    Specifies whether your site automatically shares presentations with remote sites once presentation input is detected.

    The default value is Disable.

    Dynamic bandwidth

    Specifies whether the endpoint implements the following if audio and video quality decreases (such as increasing packet loss rate and network latency) are predictable 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.

    The default value is Disable.

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

    Low-bandwidth video

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

    After Low-bandwidth video 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.

    The default value is Enable.

    SIP keep-alive period (s)

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

    The default value is 30.

    BFCP keep-alive period (s)

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

    The default value is 10.

    AES256 encryption

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

    The default value is Disable.
