I have been doing VoIP over sat to northern Canada and Latin America for
more than five years now, using Cisco routers with analog and digital voice
ports, and also IP phones. Other than the inevitable lag due to 500+ ms RTT,
the voice quality with the G.729 codec has been good. I have lost count of
the number of mining operations in northern Canada that rely in VoIP over
sat for communication with the civilized world. Some of the bigger
operations have in excess of 500+ Cisco IP phones.

Alaska has a lot connections doing VoIP over Sat also. Most of the state is served by Sat connections, being the largest state in the U.S.
