We have built an Asterisk network using an MPLS-based IP VPN. We have one 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.

We have a few satellite trunks for VoIP in Africa and have some experience.

Adam, I personally think that replacing hard-wired network and going with Sats is a mistake. Judging from pure round-trip delay you measured the packet round trip seems sufficient to have a good conversation, but pinging is not enough to trouble shoot the network problems. You will need to do a lot more work to identify the problem with this location. If both locations are under your control, then I would put network probes in both places to identify exactly when and how the quality problems appear. Network probes would identify the type and the amount of traffic both sides are sending and receiving. There are network probes that can even do Voice Quality Analysis and determine how well your network is performing. As a side step, I would also look at internal location in New Brunswick, because that is the only location you are having problems with. I would check to see if there are simple network problems like bad network port, network card, packet collision on the network, network card on routers, etc. I am sure you have already considered simple things like that, however you need to methodically go thru each one to see where the problems are. Replacing the network would be my last alternative. If you are at that point, well.... then just ignore this email. Otherwise, there are plenty of things you can do before taking such a drastic measure.

I have no experience in the matter whatsoever ;) But, I can say that long distance phone calls (non-voip) are sometimes carried over sattelite when fiber is not available. It must be possible for voip, but the latency and jitter would be tremendous and although I am not an expert on the matter, I would suggest that you would only be replacing one set of problems with a new set of problems.

Sattellite links aren't cheap, and, the worst of all, you have in a "idel" condition, 1.4 seconds latency. Hope this help...

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.
