Description
Worried about unauthorized long-distance calls or employees tying up phone lines for hours? The Viking TR-1 gives you precise, programmable control over outgoing calls — all without any external power supply or complicated wiring.
The TR-1 installs discreetly inside a standard RJ11C jack, so it stays completely out of sight while it monitors and manages every call placed from that line. A built-in call timer automatically disconnects calls anywhere from 0.5 to 49.5 minutes, and you can program an allow or restrict table with up to forty 12-digit phone numbers, prefixes, or area codes. Need to block a whole area code but still allow 1-800 numbers and emergency calls? No problem — the TR-1 handles that logic right out of the box. A 6-digit bypass code gives trusted users a one-time override without changing any settings.
This unit works equally well in offices, hotel rooms, breakrooms, or any location with a standard analog phone line. Compatible with both Touch Tone and rotary phones, and backed by non-volatile E2 memory that retains all programming through power interruptions, the TR-1 is a low-maintenance solution that keeps working quietly in the background.
Our Expert Take: The TR-1's concealed form factor is a genuine advantage in shared or public spaces — because it's hidden inside the jack itself, users can't tamper with or bypass it simply by unplugging a visible device. The programmable ignore table is especially useful for blocking feature codes like *67 or *69 that you don't want staff using, while the separate bypass code keeps management in control without disrupting legitimate calls. If you need to manage multiple lines, deploying one TR-1 per jack is a clean, scalable approach that requires zero rack space and no power runs.
