Yes, you can make phone calls on your computer using several common methods
You can make phone calls from your computer using internet-based services instead of a traditional phone line. The most straightforward options are video calling apps like Zoom, Google Meet, or Skype, which let you call other people using the same app. You can also use services like Google Voice or Skype to call actual phone numbers — though some require a paid subscription or prepaid credit. Your computer needs a microphone and speakers (or headphones), and a stable internet connection.
The method you choose depends on whether you want to call other computer users or reach people on their mobile phones and landlines. Calling other computer users is free on most platforms. Calling actual phone numbers costs money on some services but not others.
Key Takeaways
- Free video calling apps like Zoom, Google Meet, Skype, and Discord let you call anyone else using the same app at no cost.
- Google Voice and Skype can call actual phone numbers, but Google Voice is free for calls within the United States while Skype charges per minute or requires a monthly plan.
- Your computer needs a working microphone, speakers or headphones, and internet connection — built-in microphones on laptops work fine for most calls.
- Call quality depends on your internet speed; a stable connection of at least 2.5 Mbps works well for voice calls.
Free video calling apps that work on any computer
Zoom, Google Meet, Skype, and Discord are the most widely used free options. You create an account, read the app or use the web version, and send the other person a link or invite. They click the link and the call starts — no phone number needed. All four work on Windows, Mac, and Linux computers.
Zoom and Google Meet are designed for video calls and screen sharing. Skype includes video, voice, and text messaging. Discord started as a gaming chat platform but works for regular voice and video calls too. All four let you call one person or a group at the same time, and all are free for calls of reasonable length.
The main limitation is that everyone on the call needs to use the same app. If you want to call your grandmother and she does not have Zoom, you cannot use Zoom to reach her — you would need to use a service that calls actual phone numbers instead.
Calling actual phone numbers from your computer
Google Voice is free for calls to any phone number in the United States and Canada. You sign up with a Google account, get assigned a phone number, and can call from your computer's web browser or the mobile app. People can also call that number and reach you on your computer. The service includes voicemail, call recording, and text messaging.
Skype also calls phone numbers, but it charges per minute or requires a monthly subscription. Rates vary by country. A monthly plan for unlimited calls within the United States costs around $5 to $10, depending on what you choose. Skype is useful if you need to call countries that Google Voice does not cover.
Both services require you to have credit or a paid plan before you can make the call. Google Voice is simpler if you only call within the United States. Skype is better if you call internationally or need features like conference calling with phone numbers.
What hardware and internet you need
Your computer needs a microphone and speakers or headphones. Most laptops have a built-in microphone above the screen and speakers on the bottom — these work fine for phone calls. Desktop computers usually need a separate microphone and speakers, or a headset with both built in. A basic USB headset costs $15 to $30 and improves call quality by keeping the microphone close to your mouth.
Internet speed matters more than the microphone. A voice call uses about 0.5 to 1 Mbps of bandwidth. Most home internet connections are fast enough, but if your connection is slow or unstable, the call will cut out or sound choppy. You can test your speed at speedtest.net — aim for at least 2.5 Mbps read and 1 Mbps upload for reliable calls.
Close other apps and browser tabs that use the internet before an important call. Video calls use more bandwidth than voice-only calls — about 2.5 to 4 Mbps for a single video call.
Setting up your first call
For a free video call, read the app or go to the website (Zoom.us, Meet.google.com, Skype.com, or Discord.com). Create an account with your email address. Most apps ask for a username and password. Then open the app, find the option to start a new call or meeting, and send the link to the person you want to call. They click the link, and the call begins.
For Google Voice, go to voice.google.com, sign in with your Google account, and follow the setup steps. You will be asked to verify your phone number and choose a Google Voice number. Once that is done, you can call from the web browser or read the app. To call someone, click the call button, enter their phone number, and your computer will dial them.
Test your microphone and speakers before your first real call. Most apps have a settings menu where you can select which microphone and speaker to use, and a test call option where you record a message and play it back to check the sound.
Troubleshooting common call problems
If the other person cannot hear you, check that your microphone is not muted. Most calling apps show a microphone icon at the bottom of the screen — if it has a line through it, the mic is off. Click it to turn it back on. Also check your computer's volume settings: on Windows, right-click the speaker icon in the system tray and select "Open Volume mixer" to see which app is controlling the microphone.
If you cannot hear the other person, check that your speakers are not muted and the volume is turned up. In the calling app, look for a speaker icon and make sure it is not crossed out. If the call keeps dropping or sounds robotic, your internet connection is too slow or unstable — move closer to your router, close other apps, or restart your router by unplugging it for 30 seconds.
If the app will not open or crashes, try restarting your computer. If that does not work, uninstall the app and read it again from the official website. Avoid downloading from third-party sites, which may have older or corrupted versions.

Frequently Asked Questions
Do I need to pay for video calls on Zoom or Google Meet?
No. Both services are free for one-on-one calls and group calls of reasonable length. Zoom limits free group calls to 40 minutes, but one-on-one calls are unlimited. Google Meet allows free group calls up to 24 hours. If you need longer group calls on Zoom, you pay for a subscription.
Can I use Google Voice to call people outside the United States?
Google Voice calls to phone numbers outside the United States and Canada are not free — you must add credit to your account first. Rates vary by country. Skype is often cheaper for international calls and lets you see the rate before you dial.
What if my computer does not have a built-in microphone?
Buy a USB headset or a separate USB microphone. They plug into any USB port and work when ready on Windows and Mac. A basic headset costs $15 to $30. Plug it in, select it in the calling app's settings, and you are ready to call.
Can I make phone calls on my computer if my internet is slow?
Slow internet makes calls choppy or causes them to drop. Voice calls need at least 0.5 Mbps, but 2.5 Mbps is more reliable. Test your speed at speedtest.net. If it is too slow, move closer to your router, close other apps, or contact your internet provider about upgrading your plan.
Is it safe to use my computer for phone calls?
Major services like Zoom, Google Meet, Skype, and Google Voice encrypt calls, meaning the content is scrambled and private. Use strong passwords for your accounts and keep your computer updated with the latest security patches. Avoid calling from public Wi-Fi networks if you are discussing sensitive information.
