Hack a VOIP Box Into a Telephone Intercom

Step 18 Configure Ring

If it worked, you might want to configure your ringdown for a ring different from your regular telephones. Here is where you set it. Basically, switch another ring cadence with Ring1 Cadence. Be sure to click when done.

That's all there is to it! Enjoy your new telephone intercom/ringdown. Even if you bought your PAP2T new, you likely saved at least 66% off the cost of a basic ringdown module.
