   Table 3-19  Advanced conference parameters

   Parameter	Description	Setting
   Audio protocol	Specifies the audio protocol the endpoint uses to encode audio.	The default value is Auto.
   Audio channels	Specifies the audio channels. This parameter is available when Audio protocol is set to AAC-LD or HWA-LD.	The default value is Two.
   Video protocol	Specifies the video protocol the 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.264 HP-related 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. When Video protocol is set to Auto, this parameter is not available. Video at a higher frame rate is smoother. Video at a lower frame rate is clearer.	It is recommended that you set this parameter to Auto.
   Prevent little 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 resolution, Presentation mode, Presentation bandwidth setting, Presentation sharing mode, and Presentation plug-and-share only after you set this parameter to Enable.	The default value is Enable.
   Presentation protocol	Specifies the video protocol the endpoint uses to encode presentations.	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: Smooth: Your endpoint uses a high frame rate to ensure smooth video. Sharp: Your endpoint uses a high video resolution to ensure clear video.	The default value is Sharp.
   Presentation mode	Specifies the mode of the presentation you want to share. Presentation: When the video is switched, the presentation remains unchanged. Only one site in the conference can share a presentation one time. Live: The presentation viewed by each site is switched along with the video. All sites in a conference can share presentations simultaneously. NOTE: When connected to an IMS network, the endpoint cannot share a presentation in Live mode.	The default value is Presentation.
   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.
   Presentation sharing mode	Specifies the mode for sharing presentations. Auto: The endpoint automatically shares presentations along with videos. This parameter can be set to Auto only when Presentation mode is set to Live. Manual: You must manually share presentations by using the remote control button or through the web interface. For details about how to share presentations through the web interface, see Sharing a Presentation.	The default value is Manual.
   Presentation plug-and-share	After this function is enabled, once a presentation source is connected to the endpoint in a conference: If a site is sharing a presentation, the endpoint will display a message asking you whether to starting sharing the presentation. If no site is sharing presentations, the endpoint automatically starts sharing the presentation. If the endpoint is not in any conference, once a presentation source is connected, the endpoint automatically starts sharing the presentation.	The default value is Disable.
   Share content in video channel	If the local or remote endpoint does not support presentation sharing or has this function disabled, set Share content in video channel to Enable so that the shared presentation will be transmitted through the video channel.	The default value is Disable.
   Dynamic bandwidth	Specifies whether the endpoint implements the following if the packet loss rate increases 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.
   Conference bandwidth	Specifies the transmission bandwidth for a conference. If your endpoint accesses an E1 network through an IP line, set this parameter to Limited for better video conference quality.	The default value is Normal.
   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.	The default value is Auto.
   Conference line type	Specifies the type of line used during a conference. If you select Auto and your endpoint has registered with a network gatekeeper (GK), your endpoint preferentially uses H.323 to initiate a conference.	The default value is Auto.
   Preferred IP protocol	Specifies the protocol that IP sites preferentially use. When Line type is set to Auto for IP sites, your endpoint uses this protocol to call the IP sites.	The default value is H.323.
   Reserved presentation bandwidth	Disable this parameter if your site is not going to send or receive presentations during a conference and the Received value for Presentation bandwidth [frame rate] is not -. If this parameter is disabled, the Received value for Presentation bandwidth [frame rate] restores to - when you rejoin the conference. NOTE: To view the Presentation bandwidth [frame rate] value, choose Maintenance > System Status > Conference.	The default value is Enable.
   Face detection	Specifies whether to perform HD encoding and decoding to improve face recognition video quality. You can increase the video sharpness by enabling this parameter in low bandwidths.	The default value is Disable.
   Second dial mode	Sets the second dialing method.	The default value is Auto.
   Preferential Display for H.323 ID	Specifies whether to preferentially display the H.323 ID when the endpoint receives a call.	The default value is No.
   LifeSize Networker mode	If this mode is enabled, the endpoint will use the LifeSize ISDN gateway to place calls. In this case, Conference line type must be set to H.323 or AUTO. After the calls are set up, some of the endpoint's functions may be restricted. NOTE: After enabling the LifeSize Networker mode, you must set LifeSize Networker IP address.	The default value is Disable.
   LifeSize Networker IP address	Specifies the IP address of the LifeSize ISDN gateway.	No default value is set for this parameter. Obtain the IP address from the network administrator.
   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.
   SIP keep-alive period (s)	Specifies the interval at which the local endpoint periodically sends SIP link keep-alive packets to the remote endpoint.	The default value is 100.
   BFCP keep-alive period (s)	Specifies the interval at which the local endpoint periodically sends BFCP link keep-alive 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.
   Interworking with Polycom	After this function is enabled, the endpoint: Connects to the Polycom recording server. Supports video interoperability through H.263 in the H.323 environment. Saves layout settings locally.	The default value is Disable.
