5 Ways that ACTUALLY Work


Nobody wants unsolicited calls. To start, you can register your number on the U.S. Do Not Call Registry via their website or by calling 1-888-382-1222 (TTY: 1-866-290-4236).

Unfortunately, while it’s a good first step, it won’t stop spam calls.

The Do Not Call Registry only stops unsolicited calls made by legitimate businesses. Scammers rarely operate legit businesses, and spam calls are a tool of their trade. Here are some ways to stop the spam.

How to Stop Spam Calls With Your Phone

Block unwanted calls with your phone’s built-in features

Most smartphones on the market today include a feature to block unknown numbers. This is a pretty good way to keep scammers from getting through, but it comes at a cost.

If you turn on this feature to block unknown numbers, you may miss out on legitimate calls, too. Delivery drivers, a doctor’s office, or an acquaintance calling from a new number are all people who may be blocked when this setting is active.

But if the comfort of eliminating spam calls, including the super-annoying ghost calls, outweighs an occasional missed call you did want to get, here’s how to set the feature up on your phone.

Block calls on iPhone

Step 1. Open the Settings app.

Step 2. Choose Phone > Silence Unknown Callers.

Step 3. Toggle the Silence Unknown Callers button to ON.

This will send unknown numbers straight to voicemail without notifying you of the incoming call. You will, however, still find the number in your Recents list.

With this setting active, only numbers in your Contacts list and numbers you’ve recently called will ring through to your phone.

Block calls on Android

Step 1. Open your Phone app and tap on More info (three dots) in the upper-right corner.

Step 2. Select Settings > Spam and Call Screen.

Step 3. Toggle Caller ID & Spam Protection to ON.

Step 4. Select Block numbers.

Step 5. Toggle the Block spam and scam calls to ON.

With these settings active, the only calls that will get through are from numbers in your Call History or Voicemail.

Block calls manually

This is the way to block one-off calls as they come in. But since scammers usually have a bank of different numbers they use to blast out spam calls, this isn’t going to fully solve the issue. It will, however, keep a specific number out of your phone–and life–forever.

Block individual calls on iPhone

This is how to block a call after you receive it.

Step 1. Open your Phone app.

Step 2. Select the Favorites, Recents, or Voicemail option.

Step 3. Select the “i” icon next to the number you want to block.

Step 4. Select Block this Caller.

Step 5. Select Block Contact on the popup confirmation screen.

Have a number you want to block before you get a call from it? You can do that, too.

Step 1. Open your Contacts list and create a new contact for the unwanted number. Don’t worry, this is just temporary. you’ll delete it later.

Step 2. Open your Settings app.

Step 3. Go to Phone > Blocked Contacts.

Step 4. Tap Add New… at the bottom of the screen.

Step 5. Your phone Contacts list appears, find the contact and select it. The contact will now appear on your Blocked Contacts list.

Step 6. Go back to your Contacts list and delete the contact.

Block individual calls on Android

Android phones vary slightly depending on the manufacturer and the operating system. But these are the general steps for blocking a call you already received.

Step 1. Open the Phone app.

Step 2. Go to Recent Calls or Call History.

Step 3. Choose the number you want to block.

Step 4. Tap the More info (three dots) in the upper right corner of the screen, then choose Block.

Step 5. Select Block/report spam.

Step 6. On the popup screen, tick the box for Report call as spam and then choose Block.

If you have a number you want to block before the call comes in, you can do that, too.

Step 1. Open your Phone app.

Step 2. Tap the More info (three dots) in the upper right corner of the screen, then choose Settings.

Step 3. Choose Block numbers.

Step 4. Type in the number you want to block, then tap the + icon.

Block individual calls on a landline

If you have a landline, your service provider may offer call blocking as an optional service. Sometimes this service is free, other times there is a small fee. But it usually only permits you to block one number at a time and caps out the total amount of numbers you can block.

For example, AT&T offers a Call Block/Call Screening feature that lets you block up to 10 unwanted numbers from your local calling area, but the service incurs a small monthly fee.

The process to block individual calls varies by provider, so you should contact yours and ask about options and fees to block unwanted calls. Generally, it involves activating the feature by dialing *60 on your phone.

How to Stop Spam Calls With Call-Blocking Devices

If you want to block spam callers on your landline, a call-blocking device may be your best bet. There are two ways to do this. You can buy a handset that has the technology built in or add an external device to the phone line.

Here is our top choice for each.

Handset with built-in spam blocking technology – AT&T DL72210

This cordless phone has three built-in features that make it a good option for managing spam calls on your landline.

There is a large Call Block button front and center on the handset that lets you ignore and block any call when it comes through. It just takes one click to rid yourself of an unwanted number forever.

The phone also includes a smart blocking feature that works by comparing numbers in your saved phonebook to every incoming number. If there’s a match, the call comes through. If the incoming number isn’t recognized or the caller can’t be identified via caller ID, additional screening takes place.

There are two modes you can set.

Screen Robot mode requires the caller to press # before the call rings through. If they don’t, the call is automatically rejected.

Screen Profile mode ups the ante and requires the caller to record their name, then press # to get their call through. If they do, you’ll hear the recorded message when you answer and can choose to answer the call and add the number to your phonebook, send the call to voicemail, or block the number.

The AT&T DL72210 costs $59.99 for two handsets from Best Buy.

External spam call blocking device – CPR V5000

This is a call blocker device you plug in to your landline. It relies on a database of 5,000 pre-programmed known spam and nuisance numbers to identify and automatically block unwanted calls. You can block an additional 1,500 numbers.

Blocking a call is easy to do with the giant red Block Now button located in the middle of the device face. When an unwanted call comes in, you press the button and the call is declined and blocked. If you miss or accidentally answer a spam call, you can use the Call List button to scroll through the last 20 received calls and block the number, too.

You must have Caller ID service enabled on your landline for devices like this to work. The CPR V5000 costs $89.99 on Amazon.

How to Stop Spam Calls With VoIP

Many people have given up traditional landline service in favor of VoIP for their residential calling needs. If you’re using VoIP for your home phone service, you’ll likely have spam call management features built-in. The key is knowing where to find these options and how to activate them.

If your VoIP service is through your internet service provider, visit the provider’s website to see if spam call blocking is available and how to enable the feature. Here’s how to manage spam calls on some of the top independent VoIP residential service providers.

Google Voice

Google Voice offers a few different ways to identify and block spam calls. If Google thinks an incoming call is spam, it will mark the call with a warning message.

To block that number, go to your call history and choose the call that is suspected spam. The warning banner will appear in the call details. Select Confirm spam. Going forward, any calls or messages from this number will be sent directly to your spam folder.

You can also block all known spam numbers. Open your Voice app. Tap Menu (three lines) > Settings. Look for the Filter spam option under Security and toggle it ON. This will automatically block any number Google has previously confirmed as spam and send it straight to your Spam folder.

To block any individual number, open your Voice app, then go to Messages, Calls, or Voicemail. Open the item you want to block, then select More options (three dots) > Block number > Block.


You must have an Ooma Premier subscription to use these features. Log into your Ooma account and go to Preferences > Call Blocking. There you will find all the different options you have for dealing with spam calls. You can set parameters for all of the following services:

  • Custom call blocking
  • Suspected spammer call blocking
  • Known spammer call blocking

  • Block all incoming SPAM? calls

To set up preferences for all of these options, sign into your Vonage account, navigate to the Summary tab, and go to the Features & Settings section. On the Calling Features tab in that section, find the Features & Settings area and click the Edit link on the Spam Call Block line. From there you can select how you want spam calls to be handled.
