[Asterisk-biz] VoIP over satellite

[Eric Hall]

That 1 second each direction you talk about. Is that to start that call?
I would say 1 second delay is not usable for most.

The latency problem won't go away regardless of what equipment you have
on either end.  It is a simple time/distance equation and you can
generally figure on about 1 second each direction.  These geosyncronous
satellites are about 26K miles out and it just takes time to send the
signals.
