Understanding Unwanted Landline Calls and Why They're a Problem

Unwanted landline calls have become one of the most common complaints received by the Federal Communications Commission (FCC). According to the FCC's 2023 Robocall Complaint Dashboard, consumers filed over 200 million complaints about unwanted calls and texts in a single year. These calls range from telemarketers and scammers to debt collectors and political campaigns. For many households, unwanted calls interrupt meals, work, sleep, and family time multiple times per day.

The types of unwanted calls vary widely. Robocalls—automated calls that use recorded messages—account for a significant portion of these complaints. Scam calls attempt to trick people into sharing personal information or sending money. Telemarketing calls promote products or services, while some calls involve silent or dead air followed by a sales pitch. Debt collection calls may occur even when someone doesn't owe money, or when the debt has already been paid.

Landlines remain particularly vulnerable to unwanted calls because they're often listed in public directories and have been around for years, meaning numbers accumulate on calling lists. Unlike mobile phones, which people may replace every few years, landline numbers can stay the same for decades. This makes them attractive targets for people running calling campaigns.

The impact on daily life is real. Studies show that unwanted calls increase stress and anxiety, particularly among older adults who may be more vulnerable to scams. Many people now hesitate to answer their phones because they fear the call is unwanted. This creates a barrier to legitimate communications from doctors' offices, schools, and family members.

Takeaway: Understanding that unwanted landline calls are a widespread problem—not a personal issue—is the first step toward addressing them. Knowing the types of calls you might receive helps you recognize them when they happen.

How Call Blocking Technology Works on Landlines

Call blocking for landlines operates differently than it does for mobile phones, because landline systems were built on older technology. Most modern landline call blocking works through one of three main approaches: network-level filtering, device-level blocking, or third-party apps and services.

Network-level filtering happens at your telephone company's central office. Your phone service provider can implement filters that catch known robocalls and scams before they reach your line. The FCC has required telephone companies to offer customers the option to use call-blocking services at no extra cost. Many providers now offer this automatically or allow customers to turn it on through their account settings. This type of blocking doesn't require any equipment changes on your end—it works invisibly in the background.

Device-level blocking occurs through equipment you control. If you have a modern landline phone or a phone adapter for internet-based phone service, you may be able to program the device itself to block certain numbers or types of calls. Some devices allow you to create a "whitelist" of numbers you want to accept and reject everything else. Others let you block numbers that match certain patterns, such as calls from numbers that differ from yours by only one digit—a common scam tactic.

Third-party services and apps represent another option. Some companies offer standalone call-blocking boxes that sit between your phone line and your phone. These devices analyze incoming calls and use databases of known spam numbers to determine whether to allow the call through. Services like this typically require a one-time purchase or monthly subscription fee. Some internet-based phone services include call-blocking features built into their apps or web portals.

Effective call blocking typically combines multiple layers. A call might be filtered at the network level first, then at the device level if it passes through. This layered approach catches more unwanted calls than any single method alone.

Takeaway: Most landline call blocking happens silently through your phone company's network, but you often need to turn this feature on. Check with your provider about what options they offer and how to enable them.

Steps to Block Calls Through Your Phone Company

The easiest way to start blocking unwanted landline calls is to contact your telephone service provider directly. Whether you use a traditional wireline company, cable-based phone service, or an internet-based phone service, the provider has tools available to reduce unwanted calls. The specific steps vary by company, but the process generally follows a similar pattern.

First, call your phone company's customer service number—it's on your monthly bill. Explain that you want to turn on call-blocking or call-filtering features. Most major providers now offer this at no additional cost. Common programs include AT&T Call Protect, Verizon Call Filter, CenturyLink Call Guard, and Windstream SafeCall. Your provider may automatically enroll you in basic blocking, which stops known spam calls without you having to do anything. Some providers offer enhanced versions with additional features that may have a small monthly fee.

Once you've selected a call-blocking service through your provider, ask how to manage it. Many services have a web portal or smartphone app where you can view blocked calls, mark numbers as spam, or add numbers to a block list. Some allow you to create a list of numbers you always want to accept—your whitelist. Keep this list updated with family, friends, and important contacts like your doctor's office.

Your phone company representative can walk you through the settings. Ask them to explain what happens to blocked calls—do they go to voicemail, or do they not ring through at all? Different services work differently. Some reduce the number of rings before sending a call to voicemail, which signals to scammers that your line might not be active, potentially removing you from their lists.

If you're not satisfied with your current provider's call-blocking options, ask about alternative plans or services they offer. If they don't provide adequate options, you might research switching to a provider with better tools in your area.

Takeaway: Contact your phone company first—they likely offer free or low-cost call-blocking tools you can turn on today. This is often the most effective single step you can take.

Additional Blocking Options Beyond Your Phone Company

Beyond your phone company's built-in services, several other tools and devices can help block unwanted landline calls. These options work alongside network-level filtering to provide additional layers of protection, particularly for calls that slip through the first layer of defense.

Standalone call-blocking devices are physical boxes that connect between your phone line and your telephone. These devices contain databases of known spam numbers and analyze each incoming call before it reaches your phone. Products like CPF Devices, TrueCaller for landlines, and others retail for between $40 and $200, with no ongoing fees. Some newer models also let you whitelist important numbers and set different rules for different time periods—for example, blocking all calls during night hours except those from family members.

If you have a modern phone system or internet-based phone service, your provider may offer a dedicated app or web dashboard for managing calls. These platforms let you see real-time caller information, block numbers instantly, and report spam to help protect other users. Some services use artificial intelligence to recognize patterns in incoming calls and predict which ones are likely scams, even if they haven't been previously reported.

Phone-answering services and virtual assistants represent another approach. Some households use services where calls go to an automated system that asks callers to state their name and purpose. The system then alerts you to the incoming call and you can choose whether to accept it. This adds a human-verification step that many scammers avoid because they don't want to state their true purpose.

For households with multiple phones or complex needs, some people combine several approaches. They might use their phone company's network filtering plus a standalone device plus a whitelist system on their phone itself. This redundancy means fewer unwanted calls reach you.

Takeaway: Investigate standalone blocking devices or apps if your phone company's free service doesn't reduce unwanted calls enough. Many cost under $100 and work for years without recurring fees.

Understanding Your Legal Rights and Protections

Several federal laws protect landline users from unwanted calls and give you rights regarding how these calls are handled. Understanding these laws helps you know what kind of calls are illegal and what steps you can take to stop them.

The Telephone Consumer Protection Act (TCPA) of 1991 is the primary federal law governing unwanted calls. It prohibits telemarketers from calling before 8 a.m. or after 9 p.m. in your
