Hack a VOIP Box Into a Telephone Intercom

Step 17 Plug in and Test

We're done configuring, so be sure to click "Save Settings" in the PAP2T web interface. You only have to do it at the end, it is not necessary to do it between tabs. Let the box do its reboot. Now, plug in your phones and try it.

Here's a shot of the back of the PAP2T and the switch. Plug a phone into each line and the ethernet jack into your switch or hub. If you're connecting to the existing house wiring, be sure the line has no connection to any other VOIP adapter or the phone company.
