Handset to Handset Intercoms

A handset-to-handset intercom is like it sounds in that it uses phone-like handsets to make calls between each other. The Two-Way Ringdown Circuit device below can be used to connect standard analog phones together to create a self-contained intercom system where other phones ring when one is picked up. The Hot Line Analog Intercom units can be programmed with a phone number that they call when the button is pressed. Likewise, the Hot Line SIP Intercom can be used on VoIP telephone systems.
