Description
If weak or distorted ring signals are causing missed calls at your doorboxes or analog terminals, the Viking RG-4 is the straightforward fix that gets every phone ringing reliably again.
The RG-4 is a ring shaper and booster that takes troublesome ringing signals — including distorted square wave output from ISDN terminal adapter ports or underpowered PABX/KSU stations — and converts them into a clean true sine wave ring signal at a full 4 REN of ring power. That means more phones ringing per line, fewer missed calls, and no more hunting down the source of an unreliable ring. It works seamlessly with Caller ID and distinctive ringing services, and it won't interfere with normal line operation once installed.
Whether you're extending ring coverage from a Viking doorbox to multiple phones or solving chronic weak-ring problems on an aging analog station, the RG-4 drops right into your existing setup with easy installation and no special tools or programming required.
Our Expert Take: The RG-4 is especially useful when pairing Viking doorboxes with older analog systems or ISDN terminal adapters that simply don't push enough ring current to drive multiple phones. Rather than replacing hardware, this compact booster solves the problem at the source. Just keep in mind that the RG-4 is not compatible with pulse dialing, so confirm your system uses tone dialing before installing.
