A system and method for re-routing a failed video call schedules one or
more reserve video devices for use in the event of failure of the video
devices selected to support a video call. Upon detection of a failure of
a video device, the video network platform re-establishes the video call
by using the reserve video devices to replace the failed video device,
thus avoiding the waste of video network resources and delays in the
completion of a video call. More efficient use of reserve video devices
is obtained by pooling the reserve video devices with a reserve video
network that supports plural primary video networks.
