Well I just cant get the darn thing to work in the Loud Ringer Adapter application. Installed in bottom of a 12 button keyset and see a constant 25VDC sitting on the T&R. No reaction to ringing current at the keyset. Have followed mannual instructions for configuring the LRA. Has anyone out there made this thing work. Maybe there is sometyhing else faulty or should be turned on, but i really dont know how to troubleshoot it. Any help would be appreciated. THANX
