You could potentially damage the hub in the worst case. In the best case, it won't work. The dialtones will conflict with each other. Someone else recently had it hooked up that way and it didn't work for them.

Ringing voltage is between 90 and 100 volts but not a lot of current so it still carries a "class C" wiring designation. But the bigger problem is if there is also dialtone or even talk battery on those lines. Then the systems do not play well together. Also, there could be a privacy issue. If the pair that serves your house is not disconnected at your network interface block then your phone line could reach other subscribers (depending on how well the telco's installation crew followed policy). Interferance can also be a problem. But none of this is as severe as backfeeding a generator to your powerline in a blackout. That can fry line crews working on the high voltage side of the line because the same transformer that can bring transmission voltage from 14.4 kilovolts to 120 V for your house can take the 120 V from your generator and turn it into 14.4 kilovolts!

Thanks again guys. On one other final side note about porting. I had ooma email me and say I had to fill out the LOA and email them a scan of my bill. Can I email the LOA as well or does that actually need to be mailed to them? If so what email address, just reply to the one they attached it to me on first?

They both go to

I recommend putting both attachments in the same email so they can't get separated.
