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

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.
