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 IP VCR. 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 a content channel using H.239 when making a new recording.

Whether this endpoint is allowed to receive a separate H.239 video stream when playing back a stored recording.

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

• Name: This must be the name that the endpoint sends to the IP VCR
• IP address: The IP address of the endpoint
• E.164: The E.164 number with which the endpoint is registered with the gatekeeper

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

When you configure Call-in match parameters, an endpoint will be recognized as this pre-configured endpoint and the Connection parameters will be applied to a call from this endpoint.

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 > Connections page.
• Favor motion: the IP VCR will try and use a high frame rate. That is, the IP VCR will strongly favor a resolution of at least 25 frames per second
• Favor sharpness: the IP VCR will use the highest resolution that is appropriate for what is being viewed
• Balanced: the IP VCR 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 IP VCR. This setting controls how the IP VCR will negotiate the settings to be used with this endpoint.

Choose the setting for transmitted video resolutions from the IP VCR to this endpoint. This setting overrides the unit-wide setting on the Settings > Connections 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 IP VCR 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 IP VCR for transmissions to this endpoint.

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

These settings take priority over the Default bandwidth from IP VCR setting configured in the global Connection settings (see Connection settings).

The maximum combined media bandwidth advertised by the IP VCR to endpoints.

These settings take priority over the Default bandwidth to IP VCR setting configured in the global Connection settings (see Connection settings).

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 > Connections page.
