VIKING ELECTRONICS K-1900-5 Touch Tone Hot-Line Dialer Landline Telephone Accessory

works as described

Product purchased to replace expensive elevator "ringdown" circuit with an ordinary business line, at less than half the monthly rate. The principal instructions are printed on the face of the device and it took well under a minute to program it! Includes pretty good protection against an elevator occupant from using the phone in the elevator to make a toll call, but does not prohibit touch-tones from being sent to the intended call recipient. A great, economical product!

works well

This is exactly what I needed and works perfectly. My wife has suffered a stroke and has a hard time dialing a phone. I wanted to be sure she could reach me if I was not in the house so I programed the dialer to call my cell phone. Works perfectly every time!

Doesn't work like it is supposed to. I bought to connect to a C-2000B to dial a huntgroup external since we will be dropping our in-house phone system but it doesn't work even after following the configuration. Waste of money and time.
