- 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.
- IMPORTANT: The V5000 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.
- Powerful Blocking, Made Simple: Preloaded with 5,000 verified scam and nuisance numbers, the V5000 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 1,500 additional numbers at your command.
- Realistic & Reliable Protection: While no device can stop 100% of spam (scammers constantly change numbers), the V5000 gives you the power to shut down repeat offenders quickly and effectively - offering more control than passive filters alone.
- Hassle-Free Design: NO POWER supply needed, NO APP, and NO SUBSCRIPTIONS. The V5000 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.
- 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.
