That sounds good.  And the tech even told me he'd leave the parts to do 
that, though at the time I was wondering what he was talking about.

That makes me wonder even more how the thing works though, since that 
seems to require either 2 Comcast/public IPAs or that the CDV doesn't 
actually use IP at all.  I have been assuming that "digital voice" == 
VoIP (like Vonage), but maybe that's a bad assumption?

I can talk my cousin through doing all of that, but what are they going 
to want to know to re-provision the old RCA box?  Just plug it in and 
power it up?  MAC address?  And will they be a PITA about it, or is that 
pretty standard?  This is residential, after all.

Thanks,

software required to protect Windows from its own poorly designed and
implemented self, while the overhead incidentally flattens Moore's Law.
