After 266 comments... There are satellite specific products that may help you. However you may want to consider adding WAN Optimization to your satellite communications. While several providers offer TCP acceleration, the combination of QOS and TCP Accel might help you straighten out your VOIP and reduce the cost (i.e. the amount of data that you are billed for going over the sat link) There are a number of WAN OPT solutions that may be able to help you with your VOIP over satellite. I work for one (natch). My company Expand Networks has had a reasonable amount of success at running VOIP over Satellite in many remote locations. However a lot depends on your Sat Modem, the specific mix of traffic, bandwidth etc. Here are a few links to some whitepapers.

The guy you want to talk to though at Expand is Eric Olson, he is head of the technical team there and would give you a straight answer on what to expect. He has placed over 9000 accelerators for the US Govt worldwide. Hit the Expand website and place a call.
Another issue to be alert to since you mention that you are running VOIP to remote locations is whether the WAN OPT solution is running a diskless solution or a hard drive if you worry about running out to the far reaches of canada to replace a crashed hard drive.
Let me know if I can help.
