Our Core Telecom Products
Hotline Telephones
Desktop and wall-mount phones that dial a pre-programmed number the instant the handset is lifted: no keypad, no delay, just pick up and connect. Built for money transmitters, kiosks, courtesy stations, hotel lobbies, and high-traffic public spaces.

Hotline Dialers
Compact, line-powered dialers that trigger a pre-programmed call automatically when the line goes off-hook. Install behind any phone or panic button for instant connection.

Call Controllers
Signal generators and line-management hardware that handle what standard phone lines don't: clean disconnects, hook-flash generation, and priority line switching.
Browse Call Control Devices →
DTMF Modems
Serial-powered modems that give your software direct programmatic control of a phone line: take it on or off hook, detect rings, dial with DTMF, and decode incoming touch-tones.
