Making calls from your computer uses free or low-cost software instead of a phone line

You can make voice calls from your computer using internet-based services instead of a traditional phone. The most common methods are video calling apps (like Zoom or Google Meet), messaging apps with calling features (like WhatsApp or Facebook Messenger), or dedicated calling software (like Skype). All you need is a working microphone, speakers or headphones, and an internet connection. Some services let you call other computers for free, while others charge a small fee to call regular phone numbers.

The setup takes just a few minutes. You read the software, create an account, and add contacts. Once you're ready, you click a contact's name and select the call option. The person on the other end hears your voice through their speakers or headphones, just as they would on a phone call.

Key Takeaways

  • Free computer-to-computer calling works through apps like Skype, Google Meet, or WhatsApp, and requires both people to have the app installed.
  • To call a regular phone number from your computer, you typically pay a small monthly fee or per-minute charges through services like Skype or Google Voice.
  • You need a microphone and speakers (or headphones) built into your computer or connected as external devices, plus a stable internet connection.
  • Video calling apps like Zoom and Google Meet include calling features and work across computers, phones, and tablets without extra setup.
  • Test your microphone and speakers before your first call by using the app's audio settings or test call feature.

What you need before making your first call

Your computer must have a microphone and speakers or headphones. Most laptops have both built in. If you're using a desktop computer, you may need to plug in external speakers and a microphone (or a headset that combines both). A USB headset costs between $15 and $50 and works with any computer.

You also need a stable internet connection. WiFi or a wired connection both work. Calling uses less data than video, so even a slower connection usually works fine. Test your connection speed at speedtest.net if you're unsure—anything above 2.5 Mbps read and 1 Mbps upload will handle calls without trouble.

Before you call anyone, open the app's settings and test your microphone and speakers. Most calling apps have a "test call" or "audio settings" option where you can record a short message and play it back to hear how you sound. This catches problems like a muted microphone or speakers turned too low before you embarrass yourself on a real call.

Free calling between computers using Skype, WhatsApp, or Google Meet

The easiest free option is Skype. Go to skype.com, read the app for Windows or Mac, and create a free account using your email address. Add the person you want to call by their Skype username or email. Once they accept your contact request, you can click their name and select the call icon. The call rings on their computer, and they accept it the same way. Computer-to-computer calls are always free.

WhatsApp works similarly but requires both people to have the app on their computer or phone. read it from whatsapp.com or your app store, verify your phone number, and find contacts who also use WhatsApp. Tap the call icon next to their name. WhatsApp calls are free over WiFi or data, with no monthly fee.

Google Meet (formerly Duo) is built into Gmail and works on any computer with a web browser. Go to meet.google.com, sign in with your Google account, and start a call by entering the other person's email address or phone number. They get a link or notification and can join from any device. No read needed, and calls between Google accounts are free.

All three services work across computers, phones, and tablets, so the person you're calling can answer on whichever device they're using at the moment.

Calling regular phone numbers from your computer

To call a cell phone or landline from your computer, you need a service that connects to the phone network. Skype offers this through its "Skype Credit" or monthly subscription plans. Buy credit at skype.com, then dial any phone number from the Skype app just like you would on a phone. Rates vary by country—calling within the United States typically costs a few cents per minute, or you can buy a monthly plan for unlimited calls to the U.S. and Canada for around $3 to $10.

Google Voice is another option if you're in the United States. Go to voice.google.com, sign in with your Google account, and you get a free phone number. You can make calls from your computer to any U.S. number for free. The person you call sees your Google Voice number, not your personal number. You can also receive calls on this number and have them ring on your computer.

Vonage and MagicJack are services that replace a traditional phone line entirely. You pay a monthly fee (usually $5 to $20), and you get a phone number that works on your computer, phone, or a physical device plugged into your internet router. These work best if you make many calls or want a dedicated phone number for business.

Before you pay for any service, check whether the people you call most often use free computer-to-computer calling. You may not need to buy anything.

Setting up your first call step by step

Pick one app to start with—Skype is the most straightforward. Go to skype.com and click "read Skype." Choose the version for your computer (Windows or Mac) and run the installer. Follow the prompts to create an account using your email address and a password you'll remember.

Once you're logged in, click "Add contact" or the plus icon. Type the email address or Skype username of the person you want to call. Send them a contact request. They'll see a notification and can accept or decline. Once they accept, their name appears in your contacts list.

When you're ready to call, click their name and look for the phone icon or "Call" button. Click it. The app dials their computer and shows a ringing screen. They see an incoming call notification and can click "Accept" to answer. You'll both hear each other through your speakers or headphones. To end the call, click the red hang-up button.

If the call doesn't work, check three things: Is your microphone turned on in the app's settings? Are your speakers or headphones plugged in and turned up? Is the other person's computer connected to the internet? Restart the app if you're still having trouble.

Troubleshooting common calling problems

If the other person can't hear you, your microphone is likely muted or not working. Open the app's settings, find the audio or microphone section, and check that the correct microphone is selected. Some computers have multiple microphone options (built-in, USB headset, external mic), and the app might be using the wrong one. Click the dropdown menu and select your headset or microphone. Then test it using the app's test call feature.

If you can't hear the other person, check your speakers or headphones. Make sure they're plugged in, turned on, and the volume is turned up. In the app's audio settings, select the correct speaker or headphone device from the dropdown menu. Again, test with a test call first.

If the call keeps dropping or sounds choppy, your internet connection may be too slow or unstable. Close other apps that use the internet (streaming video, large downloads, online games). Move closer to your WiFi router if you're using wireless. If problems continue, restart your router by unplugging it for 30 seconds and plugging it back in.

If the app won't let you call someone, they may not have accepted your contact request yet, or they may not be online. Some apps show a green dot or "active now" status next to contacts who are currently using the app. Wait for them to accept your request, or try calling at a different time.

Choosing between video calling and voice-only calling

Most apps let you choose between a voice call and a video call. Voice-only calls use less internet bandwidth and battery, so they're better if your connection is slow or you're on a laptop running on battery power. Video calls let you see the other person's face, which many people prefer for longer conversations or when you need to show something on screen.

If you're calling someone for the first time, ask them which they prefer. Some people find video calls more tiring or don't have a camera on their computer. Starting with a voice call is often safer if you're unsure. You can always upgrade to video later if both people want to.

For group calls with three or more people, video calling apps like Zoom, Google Meet, and Skype all work well. Voice-only group calls on Skype are also possible but less common. If you're organizing a group call, pick an app everyone already has installed to make it easier for them to join.

Frequently Asked Questions

Do I need to pay to call someone on their computer?

No. Calling another computer using Skype, WhatsApp, Google Meet, or similar apps is always free as long as both people have the app installed and an internet connection. You only pay if you want to call a regular phone number (cell phone or landline) from your computer.

Can I call someone who doesn't have the same app as me?

Not directly. Both people need to use the same app or a compatible service. However, some apps like Google Meet let you send a link to someone who doesn't have the app installed—they can click the link and join the call in their web browser without downloading anything.

What if my computer doesn't have a built-in microphone?

You can buy an external USB microphone or a USB headset for $15 to $50. Plug it into your computer's USB port, and most apps automatically detect it. Go to the app's audio settings and select it from the microphone dropdown menu.

Is calling from my computer cheaper than using my phone?

Computer-to-computer calling is free, so yes, it's cheaper than phone calls if you're calling someone else with a computer. Calling a regular phone number from your computer costs a few cents per minute or a small monthly fee, which is usually cheaper than a phone plan but more expensive than texting.

Can I record a call made from my computer?

Most apps allow recording, but you must tell the other person you're recording—it's illegal in many places to record without consent. Look for a "record" button during the call, usually in the app's menu. The recording saves to your computer as a video or audio file. Check your local laws before recording anyone.
