Configuring H.239 settings

These settings affect the behavior of the IP VCR with regard to H.239. H.239 is the protocol that allows for an additional video channel (known as the content channel) alongside the main video channel in a video-conferencing call; for example, a user may wish to record a slide presentation from a laptop as part of a recording of themselves describing those slides.

To access these settings, choose Settings > H.239.

Refer to this table for assistance configuring the H.239 settings. After making any configuration changes, click Apply changes.

H.239 status

Controls whether the IP VCR as a whole is permitted to use H.239.

If this setting is Disabled, no new recordings will be able to use H.239, and it will not be possible to view existing recorded content during playing back.

Certain video conferencing endpoints and infrastructure such as gatekeepers may not operate correctly when communicating with equipment (such as the Codian IP VCR) which declares H.239 capability. It may therefore be necessary to set this to Disabled in order to work with legacy devices (this will, of course, also prevent H.239 video streams being used with H.239-aware equipment).

Playback H.239 in main video channel

Whether the IP VCR will render recorded content channel (H.239) video data in endpoints' main video channels when playing back recordings.

The IP VCR may not be able to open a separate H.239 channel to an endpoint when playing back a recording that includes content channel video. For instance, the endpoint may have no H.239 capability, or might be using the SIP protocol (H.239 is only supported for H.323 calls).

In these cases, if this option is set to Enabled, the IP VCR will play back the recorded H.239 video in the main video channel.
