Hi All, I am investigating the deployment of VoIP/* in Eastern European areas where there is no PSTN infrastructure. As you can understand DSL/Cable connections are a dream. The only option is satellite. Does anyone know of any satellite providers that have low enough/acceptable delays

We looked at this earlier this year and, after evaluating several companies, could not get it to work well enough. The problem didn't seem to be latency, but rather lost packets in the upstream direction. Most of the time, we couldn't even get the phone to register, but even when we could, there

Well there are several problems in your description of Satellite services. For one you are grouping several differing technilogies together as one. What it seemed like you were testing was a shared bandwidth solution typically used by providers to reduce cost. It isn't uncommon to experience

The altitude of a geostationary satellite is about 37500 km for a round trip distance of aboyt 75000 km. Light travels at 300,000 km/second, so you have a latency of about 250 ms per hop. That is just for the transit time to and from the bird. Since you have a two way conversation, a caller asking

The delay in the air is minor. Radio travels very fast through the air. Almost at the speed of light. It may travel very fast but its also a very long way, 22,000 miles up, then 22,000 miles down, then the same all over again. The latency for satellite is about 500ms round trip,
