I know satellite will have more delay, like dialing an overseas number, but other than that will it work? I don't care if it sounds like a bad cellphone connection, as long as it's understandable.

You know, I bet the latency is so great that it won't work right at all. You might want to talk to vonage and see if it'll work or shall I say work well. I mean, your downstream is satellite and upstream a modem?

I had the opportunity to do this & the results were not very satisfactory but it did work. Might be acceptable if this is your only means of communication with the outside world.

Satellite up and down, for the county mobile emergency command center. They want a system that's as failproof as possible. Currently they're looking at a switch that will have 1 or 2 landlines, 1 or 2 voip lines on satellite, and 3-5 lines using cellphone adapters. In other words, if it hits the fan they want to be able to communicate.

The last time I used a Satellite connect it was on the Sprint bus trying out the VOIP. It worked, actually sounded ok but you could tell it was like hello?...3-4 sec pause Hi!...you get the idea

Vonage said that the delay might be objectionable but it should work. Thanks for the input.
