Make all your phone jacks work with VOIP
So I just took the plunge and got a VOIP service (ITP) for my house. The only issue is that they say you can't hook it into your existing telephone wiring, so you have to use cordless phones and have the base-station plugged into your VOIP box.
This is because the voltage from the phone system will damage the box. Which is quite true.
Most residential phone systems are a star topology, which means every jack connects to every other jack.
So if you go outside to your Telephone Interface Box (if you have one) you can open it up. There's a "Customer access" section, that's just a screw to open. Open it up, and unplug all the connectors, and you've solved the issue of power. That disconnects your houses phone lines from the phone company.
The phone system should now be 100% isolated. Now you can go and plug your VOIP box into any phone jack in the house... and all of your other phone jacks will now work!! (there is a limit to the number of phones you can have hooked into the system at once. I'm not sure what that is though. 3 or less should be fine)
So now I pay $9.99 a month for local/long distance to the US and Canada, and I can still use all the phone jacks. Instead of the $39.99 a month, plus $50 of install fee's Comcast wanted from me.
