[opendtv] Re: FCC on VoIP

A bit off the topic here, but I'm with Vonage now at home and I've set it up to 
automatically forward to my cell phone if the service is down for any reason.  
I 
really don't know why they aren't building small battery backup systems into 
VoIP phone adapters.  During the big power outage last year, cable TV continued 
working, so there doesn't seem to be a problem there.
