I have no experience in the matter whatsoever ;)

But, I can say that long distance phone calls (non-voip) are sometimes 
carried over sattelite when fiber is not available. 

It must be possible for voip, but the latency and jitter would be 
tremendous and although I am not an expert on the matter, I would 
suggest that you would only be replacing one set of problems with a new 
set of problems.
