I second that suggestion.  I had a spare SPA3000 that I configured at 
the neighbor's house.  Calls to my number and certain international 
destinations are routed through VOIP transparently.  If you deploy this 
in a residential setting, I suggest picking out ONLY 9+ calls for VOIP 
and leaving 7 and 11-digit dialing alone.  And BE VERY SURE that 911 
calls will go through PSTN and promptly.  And 9911 too, while you're at it.
