interactive voice over satellite is problematic due to the inherent
latency of the signal travelling 40,000km distance to the satellite
and another 40,000km back. this adds 125ms of latency in each
direction (to/from the bird), give or take. if you remeber using
satellite for long distance

I can only comment about voice over VSAT. The propagation delay which could
be anything from 600ms to 1200ms (depending on the VSAT configuration) makes
the voice calls sound like long-distance international calls. So the users
have to be aware of the you-talk-then-i-talk phenomenon.

If anyone has any experience in getting voice and multimedia working over
VSAT links, I would be interested in hearing about your experience and learn
from your mistakes. We are doing a distance learning solution for a
government client and here is 1 remote site setup.

Hello Pieter,
As you know delay is one of the problems with VSAT. You can do nothing about
hops to the satellite and back. What you need is some prioritization/QoS in
your network for the voice traffic. There are various ways to do this.
I don't have personal experience with AutoQoS but it's a
