How Do I Choose the Best Call Blocker?

The weekend will start in a few hours, and you’re swiveling your office chair while mentally mapping out how you will spend your night. Most of it will be invested in annihilating your friend’s freshly built castle in the new MMORPG franchise you just downloaded. Picturing yourself leaning back, legs outstretched, on your gaming chair in front of the 4K TV and reeking virtual havoc gives you goosebumps.

Whether you’re in the middle of a online battle, the final scene in the new Hollywood blockbuster or a family meal with your loved ones, it’s always irritating when the phone rings at an inconvenient moment. Upon answering the telephone, you realize it’s just an automated voice message. Seething with anger, you hang up. What a sour taste to end a great meal.

Your sleep wouldn’t have been interrupted if you had a call blocker to prevent unsolicited calls from reaching your phone. Call blockers allow you to save phone numbers on a blacklist so they are intercepted without your disturbance.

The best call blockers stop unwanted calls automatically and have a high capacity for numbers you can blacklist. They have bright, easy-to-read screens so you can see incoming calls and then decide to allow or block them. Most call blockers are compatible with several line providers and even Voice Over Internet Protocol. Read further to learn all you need to select the best call blocker to meet your needs.
The amount of technology and capabilities packed into a call blocker is the primary determinant of its pricing. You’d love to have the coolest call blocker with all the bells and whistles, although you might not need all of them. Even if you can afford it, you should probably think twice about spending your hard-earned money on it.

The most expensive call blockers can reach up to $200, while a less-expensive option that could suit your needs only costs around $40. Watch out for the cheapest call blockers; they can cause more harm than good. You certainly don’t want to spend your money on a call blocker that will allow unsolicited calls and block calls from your loved ones.
If you are tired of pestering, unsolicited calls, a call blocker can help. Here are some features to consider when deciding which one to purchase:
  • Type
  • Capacity
  • Size
  • Display
  • Compatibility
  • Extras
As you read on, you will have a better understanding of how these features affect the performance of a call blocker.
Construction and Design
Call blockers can help you reclaim the rest of your day by keeping unwanted calls at bay. There are two ways they do this: either automatically by identifying calls you have previously blacklisted or by you hitting the ‘call block’ button. The automatic types usually rely on memory to store your blacklisted numbers and use your call provider’s Caller ID service to block unwanted calls. If any unwanted calls still get through, you have the option of rejecting and blacklisting the call with the single press of a button.

There are probably also certain people you know who you just don’t want to talk to on the phone, coupled with the long list of unsolicited calls. This list can sometimes run high, but don’t worry. Some call blockers have the capacity to blacklist thousands of numbers. There is even one brand that has a 6500-number capacity. With that, you could block everyone you know if you wanted to.

Call blockers are often small devices, but ‘small’ is quite relative. They come in different sizes, but are rarely as big as the phone you’re using it with and weigh less than a pound.
Performance and Ease of Use
Call blockers often have displays that let you see incoming numbers so you can block or allow them if you want. Some displays are as large as 3 inches and are backlit for better visibility. Some screens will also show the time, date, and even battery level if the call blocker is battery powered.

Call blockers often work with your telephone service providers and their level of compatibility affects their performance. It is generally ideal to go for a call blocker with extensive compatibility such as DSL, FIOS, PSTN, or VOIP to improve its versatility, but it’s ultimately your decision and depends on what you need the call blocker for.

Some call blockers have extra features like multiple modes, pre-stored known unwanted numbers, automatic deletion of old unwanted numbers and more. Some call blockers even block incoming calls that do not have identifiers, such as those listed as ‘Unavailable’, ‘Name Not Provided’, or ‘Private’.
