A customer of mine has various ships around the world with VPN over satellite links. They run our (asterisk based) PBX product.
Last week I was in a conference call with three people one of which was on a ship in the Pacific (my location is Amsterdam). This ship has an 128Kbit satellite link (without QoS), and used SNOM190 phones on board. The sound quality was perfectly adequate. We ran some tests, and when he started loading the link with traffic, sound quality dropped of course, but they were *very* satisfied. If you contact me offlist I can tell you more about their setup.

We have built an Asterisk network using an MPLS-based IP VPN. We haveone location in New Brunswick Canada that consistently gives us major quality problems, whereas the others are flawless. Quality problems take the form of static, poor voice tonality, popping & clicking, drops, sporadic echo, you name it. The latency of a QoS prioritized packet between the Canada site and our hub in Atlanta is 85ms (ping). I have been searching for an alternative network provider, but I'm told that they would all take the same route from the US into Canada, as there is simply no major backbone running into NB east of Toronto. So now I'm thinking about satellite. I have no idea if a) this would even be economically feasible, and b) if the latency would be any better. If anyone out there has had any such satellite network experience with VoIP, I like to hear from you.
