Description
Tired of someone picking up an extension and killing your fax transmission, credit card transaction, or important call mid-conversation? The Viking PJ-14 puts a stop to that immediately with proven Teleguard privacy protection.
This compact wall-mountable device gives the first phone or device that answers full control of the line. Every extension still rings normally, but once someone picks up, all other Teleguard-equipped extensions are locked out until the call ends. No more dropped modem sessions, interrupted point-of-sale terminals, or frustrated customers getting cut off. It handles up to two analog lines through a single RJ-14 jack, draws power directly from the phone line, and installs in seconds with no tools and no configuration required.
The PJ-14 fits naturally into small businesses, retail counters, medical offices, and home offices where phones, fax machines, or credit card terminals share the same analog line and accidental interruptions are a real daily problem.
Our Expert Take: The PJ-14 is one of those simple solutions that solves a genuinely annoying problem once and for all. The key thing to know is that Teleguard protection works between devices that also have Teleguard built in or attached — so for full coverage across all your extensions, you'll want a PJ-14 at each phone or terminal location on the shared line. For a busy retail counter where a credit card machine and a desk phone share the same line, this is exactly the kind of set-it-and-forget-it fix that pays for itself the first time it prevents a failed transaction.
