Configuring H.323 endpoints

The name of the endpoint.

The IP address, host name, or an E.164 address (phone number).

You can configure this endpoint as needing to be reached via an H.323 gateway without that gateway being already configured on the MCU. To do this, set this field to be <gateway address>!<E.164>.

The gateway through which the endpoint connects.

Whether this endpoint is permitted to contribute the conference content channel using H.239.

This setting takes precedence over the per-conference H.239 contribution setting for conferences that the endpoint is invited into.

Whether this endpoint is allowed to receive a separate H.239 video stream when in a conference.

These fields are used to identify incoming calls as being from the endpoint.

The endpoint is recognized if all filled-in fields in this section are matched. Fields left blank are not considered in the match.

The name that will be displayed in a conference as a label for this endpoint.

The name you enter here will override any default name configured on the endpoint. It will also override any other default name that might appear for an endpoint. For example, an endpoint's default name can be the name of the gateway through which the call was placed, or if the endpoint is called-in via a gatekeeper, its E.164 number.

Note that once an endpoint has connected, you cannot change the display name.

Choose whether to use the unit-wide setting for motion/sharpness trade off, or configure an individual setting for use with this endpoint. Choose from:

• Use box-wide setting: this is the default value. In this case, the connection to the endpoint will use the motion / sharpness tradeoff setting from the Settings > Conferences page.
• Favor motion: the MCU will try and use a high frame rate. That is, the MCU will strongly favor a resolution of at least 25 frames per second
• Favor sharpness: the MCU will use the highest resolution that is appropriate for what is being viewed
• Balanced: the MCU will select settings that balance resolution and frame rate (where the frame rate will not be less than 12 frames per second)

The settings for motion (frames per second) and sharpness (frame size or resolution) are negotiated between the endpoint and the MCU. This setting controls how the MCU will negotiate the settings to be used with this endpoint.

Choose the setting for transmitted video resolutions from the MCU to this endpoint. This setting overrides the unit-wide setting on the Settings > Conferences page

Retain the default setting (use box-wide setting) unless you are experiencing problems with the display of certain resolutions by this endpoint.

Endpoints advertise the resolutions that they are able to display. The MCU then chooses from those advertised resolutions, the resolution that it will use to transmit video. However, some endpoints do not display widescreen resolutions optimally. Therefore, you might want to use this setting to restrict the resolutions available to the MCU for transmissions to this endpoint.

Choose a border size for this endpoint's transmitted video.

This sets a border thickness to display around the video image. This is useful where the image is displaying off the edges of the participant's screen; use a border to force the image to display properly.

Applying a border size here means that this border size will always be used for this endpoint's transmitted video. Note that you can also apply a border to a participant in a conference from the Conference list > Conference > Participant's display page.

Sets the layout family to be used when calling out to this endpoint.

If this is set to Use box-wide setting then the default view family that has been configured via the Conference settings page will be used.

The network capacity (measured in bits per second) used by the media channels established by the MCU to a single participant.

These settings take priority over the Default bandwidth from MCU setting configured in the global Conference settings (see Conference settings).

The maximum combined media bandwidth advertised by the MCU to endpoints.

These settings take priority over the Default bandwidth to MCU setting configured in the global Conference settings (see Conference settings).

Whether this endpoint is able to change their view layout via Far-End Camera Controls or DTMF tones.

This setting takes precedence over the per-conference layout control setting for conferences that the endpoint is invited into.

Set the initial audio status of an endpoint to be either active or muted.

If set to muted, when the endpoint joins a conference, it will not be able to contribute audio to the conference. For example, you can mute audio from an endpoint if somebody wants to be seen in the conference, but does not want to contribute verbally. You can mute both audio and video if required. This can be altered during the course of the conference by going to Conferences and clicking on the name of a conference and altering this participant's settings.

Set the initial video status of an endpoint to be either active or muted.

If set to muted, when the endpoint joins a conference, it will not be able to contribute video to the conference. For example, you can mute video from an endpoint if somebody wants to see the conference, but not be seen themselves. You can mute both audio and video if required. This can be altered during the course of the conference by going to Conferences and clicking on the name of a conference and altering this participant's settings.

When a participant disconnects from a conference and only endpoints set to Automatic disconnection are left, all those participants are disconnected.

Set to enabled if you want this endpoint to be automatically disconnected from conferences when only endpoints set to Automatic disconnection remain in a conference when any other participant has disconnected.

Note that this setting is useful where you have configured a Codian IP VCR as an endpoint so that the IP VCR can be automatically called into a conference to record the session. In this case, the IP VCR will stop recording when the conference ends (that is, when everyone has left the conference). For more information about using the IP VCR in this way, refer to the IP VCR online help.

Can be used to ensure only specific codecs are permitted on calls to (and received from) this endpoint.

If Enabled, you can choose which codecs are allowed to be used when communicating with this endpoint. When enabled this setting overrides the unit-wide codec selection on the Settings > Conference page.
