Calling out from the IP VCR

As well as using your video endpoint to call into the IP VCR in order to make and watch recordings, you can also perform both of these functions using the IP VCR to call out to your endpoint. The sections below explain how to call out from the IP VCR to make and watch recordings:

Calling out to watch a recording

To call a video endpoint from the IP VCR in order to play a stored recording:

  1. Go to Recordings.
  2. Use the Recording list to select the recording that you want to watch.
  3. Click the recording name. The Recording information page is displayed (see Viewing and updating recording details).
  4. Click Call out and play session. The Playback parameters page is displayed.
  5. Refer to the table below for details of the fields displayed.
  6. Click Call endpoint or Call selected endpoint. The IP VCR will attempt to call the specified endpoint.
  7. Answer the call on your video endpoint to commence playback.
  8. Watch the recording as if you had called into the IP VCR. Similarly, you can control progress using the Far-End Camera Controls of your video endpoint (see Using a video endpoint to watch recording).

Calling out to make a recording

To call a video endpoint from the IP VCR in order to make a new recording, follow these steps:

  1. Go to Recordings.
  2. Browse to the folder in which you want to place the new recording.
  3. Click Call out and record. The Recording parameters page is displayed.
  4. Refer to the table below for details of the fields displayed.
  5. Click Call endpoint or Call selected endpoint. The IP VCR will attempt to call the specified endpoint.
  6. Answer the call on your video endpoint. Recording will either start immediately (see Non-interactive recording) or the recording console is displayed (see Using the recording console).
  7. Continue to make your recording as if you had called into the IP VCR.

Understanding the playback and recording parameters pages

Whether calling out to play back or to record, you must specify which endpoint you want to call. The Playback parameters and Recording parameters pages are very similar. Refer to the table below for details:

Field Field description Usage tips
Playback parameters
 

There are no playback-specific parameters.

 

Recording parameters
Name of recording to create

Specify a name for the new recording.

The name you choose will be displayed in the Recordings list (see Understanding the recordings list), and in the auto attendant menu.

You cannot choose a name that is already used by another recording.

Use recording console display

Select to call the endpoint using the Recording console to make the recording. Leave it clear to make a non-interactive recording.

See Using the recording console and Non-interactive recording for more information on the implications of this option

New endpoint
Host name or IP address

Specify the host name or IP address of the endpoint you want to call out to.

Alternatively you can specify an E.164 number if you also select an H.323 gateway.

To make a call out via a H.323 gateway that has not been specifically configured on the IP VCR, you can enter an address here of the form <gateway address>!<E.164>.

Call protocol

If the endpoint is an H.323 endpoint, select H.323. If it is a SIP endpoint, select SIP.

 

H.323 gateway

If you want to call the endpoint using an E.164 number via a previously-configured H.323 gateway, you can select an H.323 gateway from the list of configured gateways.

If you are calling by host name or IP address, you need not specify a gateway.

Use SIP registrar

If the endpoint is a SIP endpoint, and you want it to use a SIP registrar, select this option.

 

Motion / sharpness trade off

Choose whether to use the box-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 this 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.

Transmitted video resolutions

Choose the setting for transmitted video resolutions from the IP VCR to this endpoint. This setting overrides the unit-wide/blade-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.

Preferred bandwidth from IP VCR

Use these fields to specify the preferred call bandwidth from the IP VCR to the endpoint and from the endpoint to the IP VCR, respectively.

If you choose use default value, the preferred bandwidth is chosen to be the same as that set in the global connection settings.

Preferred bandwidth to IP VCR
Custom codec selection

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.

Configured endpoints
<Pre-configured endpoints>

Select one of the endpoints that has been configured on the IP VCR to call by selecting it in the list and clicking Call selected endpoint.
