Hi Henry, Bandwidth isn't your only (or even primary) concern with satellite systems. You have to look at the latency. You could have high and variable latency in one or both directions depending on the type of service you're using. I spoke with a satellite provider several months ago and they advised me that they reduce header overhead by bunching packets up and sending them in big bursts. That's really going to affect the quality of your voice and I don't think there's much that a codec change will do.
I'd run a ping for a few minutes and see what happens. Also consider that this will give you round-trip time and the latency may be very different if upstream is terrestrial (land line or whatever) and downstream is satellite. I'm not saying 'give up', just 'watch out'. Also, I remember seeing a thread along these lines a few months ago. I think there were a number of pretty intelligent responses. You might want to check the archives to get the benefit of other people's knowledge/experience. I'd be interested in knowing how you make out with it. Good Luck.
