We're off the grid (sort-of)
Yesterday night I installed our Internet-based telephone system. Basically, there's a box (the ATA-186) that plugs into the router, and then the phone plugs into the box. The phone works the same as it did plugged into the phone jack. There are several providers of this service - we went with Vonage, as it offers area code 845 phone numbers. Here's a diagram (from Vonage) of how it works:

There several advantages:
Cost: $26 a month for a "phone line" with all the usual features, free local and regional calls, and 500 free long distance minutes a month.
Portability: The phone number is associated with the ATA-186 - if I take the box (and my phone) anywhere in the world and plug it into an internet connection, when someone calls my home phone, the phone will ring! If we move across town or to another state, we can keep our old phone number
The primary disadvantage is reliability: If the cable modem connection fails, bye-bye phone service. Fortunately, we can call the cable company using the cell phone. Power failure is also a problem, but we have a 450VA UPS which should power the cable modem, router, and ATA-186 for quite some time.
...So, I called verizon and cancelled our service with them. Its pretty amazing that phone calls can be thrown around on the internet in real-time - being attached to the phone company with thousands of feet of copper wire suddenly seems so passé. Of course, we're still attached to the cable company, but one utility is better than two.
