10 Best Call Blocker For Landline Phone 2025 in the United States

The Panasonic Cordless Phone with Answering Machine (KX-TGD833M) stands out with robust call-blocking features. It can block up to 1,000 numbers with a simple one-touch button on the handset, and it even pre-blocks robocalls. This makes it particularly effective for users frequently dealing with spam calls. Additionally, it has a One-Ring Scam Alert to prevent one-ring scams, adding an extra layer of security.

Ease of use is another strong point, thanks to its illuminated keypad with large characters and a speed dial feature. The handset is lightweight and wall-mountable, making it convenient to keep the phone within reach. The expandable system with three handsets is useful for larger households or offices. Moreover, it offers bilingual Caller ID announcements (in English and Spanish), which is great for multilingual environments. Recording calls with its 2-way recording feature ensures that you won’t miss important information from conversations.

The phone’s reliance on AAA batteries (six required, though included) might be seen as a hassle for some users who prefer built-in rechargeable batteries. Also, while the Caller ID display is high-contrast and easy to read, it requires an additional phone service to function fully. This product is well-suited for individuals or offices needing extensive call-blocking capabilities, ease of use, and multilingual support, but be mindful of the battery requirements.

The AT&T BL102 DECT 6.0 Cordless Phone is designed to enhance communication at home, especially for users looking to reduce unwanted calls. One of its standout features is the smart call blocker that can block robocalls automatically, making it a great choice for those tired of telemarketers and unwanted callers. It also allows for manual blocking of any number, with storage for up to 1,000 entries, ensuring you have control over who can contact you. The caller ID announcer is a handy addition, letting you know who is calling before you pick up the phone.

Ease of use is well catered for with a large 2-inch screen and a lighted keypad, making it particularly user-friendly for those with visual impairments or anyone navigating low-light situations. The digital answering machine, capable of recording 22 minutes of messages, adds to its functionality, allowing users to never miss important calls.

There are some considerations to keep in mind. The device relies on a corded electric power source, which means it has to be plugged in, potentially limiting placement options. While the blocking features are robust, some users might find the initial setup and understanding of all the features to be a bit complex without a more detailed guide. The AT&T BL102 serves well as a call blocker and an everyday cordless phone, particularly for those prioritizing ease of use and effective call management.

The Panasonic KX-TGC362B Expandable Cordless Phone System offers a range of useful features for those looking to manage calls on their landline. It includes two handsets and a digital answering machine that can store up to 17 minutes of messages, making it practical for home or small office use. One standout feature is its call blocking capability, allowing you to block up to 30 numbers. However, this might be limiting for users needing to block more callers.

The phone system is user-friendly with its amber backlit display, which makes it easy to read in various lighting conditions. Additionally, the intelligent eco mode helps reduce handset power consumption, extending battery life to up to 10 hours of talk time and six days on standby. While compatibility with DECT 6.0 ensures good range and sound quality, the system may not support all advanced call-blocking features and filters found in more specialized devices.

The caller ID display and call list management are straightforward but lack more sophisticated whitelist/blacklist features. This product is well-suited for users seeking a modest call-blocking solution with essential cordless phone functionalities.
