It’s not really oversold bandwidth. It’s just that the turnaround time for a bolus of data is too long for two-way video conferencing to be smooth or reliable. It’s like video conferencing using post cards :)
Except that videoconferencing is just the victim of the problem, and the problem is bursty bandwidth not latency. In fact, the back-and- forth of conversation is actually surprisingly decent for satellite. Not as much "talking over" as I would have suspected. But put the victim application aside, the real data is in the iperf3 results I posted, demonstrating how bursty the throughput is. The problem with that of course is that the "lowest" bandwidth "valleys" becomes the "constant bandwidth" that the codec uses rather than the average -- which of course cannot be used for real-time VC.
