Main highlights
- Realistic & Reliable Protection: While no device can stop 100% of spam (scammers constantly change numbers), the V100K gives you the power to shut down repeat offenders quickly and effectively - offering more control than passive filters alone.
- Powerful Blocking, Made Simple: Preloaded with 100,000 verified scam and nuisance numbers, the V100K starts protecting you right out of the box. And if a new or spoofed number gets through, the large “BLOCK NOW” button makes it easy to instantly block it - up to 10,000 additional numbers at your command.
- Peace of Mind Guaranteed: Every unit includes a 3-year manufacturer warranty and lifetime customer support. Our friendly team is just a message away - contact details are included in the box for personalized assistance whenever you need it.
- IMPORTANT: The V100K CPR Call Blocker requires Caller ID service and an analog telephone line. Without Caller ID, incoming numbers cannot be identified or blocked. No mains power required - just plug it into your phone line and use.
- Hassle-Free Design: No power supply needed, no app, and no subscriptions. The V100K is easy to install, with a clear screen and loud button click for extra confidence. Designed with seniors in mind, it’s ready to use and simple to maintain. For even stronger protection, you can pair it with your phone provider’s spam filtering service.
- COMPATIBILITY: For traditional analog landline phones and services from providers such as AT&T, Verizon, Frontier Communications, CenturyLink, and Brightspeed. NOT COMPATIBLE with internet-based or digital phone services (VoIP), including Vonage, Ooma, Xfinity Voice, and Quantum Fiber.
