You’ve installed your landline call blocker, and the scam calls have nearly disappeared. But after a few months, you might wonder — should I update or refresh my blocked list?
The short answer: it depends on your device model and how frequently you receive new unwanted calls. Let’s explore how often you should update, why it matters, and how to keep your call blocker performing at its best.
Why Updating Your Blocked List Matters
Scammers and telemarketers constantly switch numbers to dodge detection. Even the best pre-programmed call blockers, like the CPR Call Blocker V100K, rely on regularly updated scam databases to stay ahead.
Refreshing your blocked list ensures:
- New scam numbers are caught.
- Old or inactive numbers can be removed.
- You maintain enough storage space for new entries.
Summary: Updating your blocked list helps your call blocker adapt to new scam tactics and maintain top performance.
How Often Should You Refresh the Blocked List?
Most users only need to refresh their device every few months, depending on call volume.
Here’s a simple guide:
- Light users (few unwanted calls): Refresh every 6–12 months.
- Moderate users: Refresh every 3–6 months.
- Heavy users or carers of elderly relatives: Check monthly to ensure protection remains strong.
If your device’s memory is full (usually 2,000–5,000 numbers), newer numbers will automatically replace older entries, so regular checks keep it running efficiently.
Summary: Refresh your blocked list every few months or sooner if you receive frequent nuisance calls.
How to Refresh or Manage Your Blocked List
Most CPR Call Blocker models make managing your list simple. You can:
- Manually review blocked numbers via the display screen.
- Unblock legitimate numbers accidentally added.
- Add new scam numbers manually.
- Factory reset to start fresh if the list becomes cluttered.
After a reset, your pre-programmed scam database remains intact — only manually added numbers are cleared.
Summary: Review, unblock, and refresh manually or perform a full reset if your list becomes full or outdated.
When Should You Update Your Device’s Scam Database?
Pre-programmed models like the V100K come loaded with tens of thousands of known scam numbers. While these lists are comprehensive, new scams appear constantly.
We recommend upgrading or updating every 12–18 months if:
- You notice more nuisance calls slipping through.
- You’ve had your device for several years.
- Your provider (BT, Sky, or Virgin) changes network settings.
Newer CPR Call Blocker models are designed to handle current scam trends, including international and spoofed numbers.
Summary: Update your device annually or when new scam patterns emerge to ensure ongoing protection.
How to Know It’s Time for a Refresh
Look out for these signs:
- You’re suddenly receiving more scam or withheld calls.
- The same nuisance number keeps reappearing.
- The device’s memory is nearly full.
- Your call log shows missed opportunities to block new patterns.
A quick review and refresh can fix most of these issues in minutes.
Summary: Rising scam activity or repeated unwanted calls indicate it’s time to refresh your blocker.
Extra Tips for Ongoing Protection
- Enable Caller ID to ensure accurate blocking.
- Register your number with the Telephone Preference Service (TPS).
- Report suspicious calls to Action Fraud.
- Use whitelist mode for essential contacts.
- Combine with provider tools like BT Call Protect for layered defence.
Summary: Combine regular list updates with TPS registration and Caller ID for maximum protection.
Conclusion
Updating your landline call blocker’s blocked list only takes a few minutes but provides long-term peace of mind. By refreshing your list every few months and upgrading when needed, you’ll ensure your device continues protecting your home from the latest scams and nuisance calls.
