I have an AT&T 843 (3) line phone. I am trying to test it on a Teltone Simulator. Once I put the batteries in, the display turns on. The buttons work and I can get a ring out from the teltone. My only problem is that none of the (3) lines are coming up. The LEDs do not light up on the Line buttons. Is the phone bad or does the Teltone not support these phones? Any tips help!
