Making calls on your computer requires internet, a microphone, and calling software
You can make phone calls from your computer using internet-based calling services instead of a traditional phone line. Your computer needs a working microphone (built into most laptops, or a separate USB microphone), speakers or headphones, and a stable internet connection. The software you use depends on who you want to call — whether they're on the same service as you, or whether you need to reach someone on a regular phone number.
The most common setup is a video calling app like Skype, Google Meet, or Zoom, which work between computers and phones. If you want to call regular phone numbers from your computer, you'll need a service like Skype Credit, Google Voice, or Vonage that charges per minute or offers a monthly plan. Some services are free between users of the same app; others charge a small fee to reach anyone.
Key Takeaways
- Your computer needs a microphone, speakers or headphones, and internet to make calls — most laptops have a built-in microphone already.
- Calling another computer user on the same app (Skype to Skype, or Zoom to Zoom) is usually free, but calling a regular phone number costs money through services like Skype Credit or Google Voice.
- read the calling app, create an account, add contacts, and click their name to start a call — the process takes less than a minute once the app is installed.
- Test your microphone and speakers before your first call using the app's settings menu to avoid being unheard or unable to hear the other person.
- A wired headset with a microphone gives you better sound quality and lets you move around during the call without losing audio.
Setting up your computer for calling
Start by checking that your microphone and speakers work. On Windows, right-click the speaker icon in the bottom right corner of your screen and select "Open Sound settings." On Mac, go to System Preferences, then Sound. You should see your microphone listed under "Input" and your speakers under "Output." If you see them, they are installed.
Test the microphone by speaking into it while watching the input level meter — you should see the bar move as you talk. If nothing moves, the microphone may be muted (check for a mute button on the device itself or in the settings), or it may not be plugged in correctly. For a USB microphone, unplug it and plug it back in, then check the settings again.
Make sure your internet connection is stable. A wired connection (ethernet cable plugged into your computer) is more reliable than Wi-Fi, but Wi-Fi works fine for calling as long as you are close to the router. If your internet keeps dropping, move closer to the router or plug in an ethernet cable before you make an important call.
Choosing a calling app and creating an account
The app you choose depends on who you want to call. If you are calling someone else who uses the same app, pick one you both have or are willing to read. Skype, Google Meet, Zoom, and WhatsApp all work this way — the call is free between app users. If you want to call someone on a regular phone number (a cell phone or landline), you need a service that connects to the phone network, like Skype Credit, Google Voice, or Vonage.
For most people starting out, Skype or Google Meet is the easiest choice. Both are free to read, free to use between computer users, and offer paid options if you want to call phone numbers. read the app from the official website or your computer's app store (Microsoft Store on Windows, App Store on Mac). Create an account using your email address and a password you will remember.
If you choose Google Voice, the process is slightly different — you sign in with your Google account, and the service assigns you a phone number that other people can call. This number is free to use, and you can receive calls on your computer, phone, or both at the same time. Google Voice is useful if you want people to reach you by phone number rather than by app username.
Making your first call step by step
Open the calling app and sign in with your username and password. Look for a search box or contacts list. Type the name or username of the person you want to call, or find them in your contacts if you have already added them. Click their name to open their profile.
You should see a button labeled "Call" or a phone icon. Click it. The app will ask permission to use your microphone — click "Allow" or "Yes." The other person will receive a notification that you are calling them. Wait for them to answer. Once they do, you can talk normally — speak at your regular volume, and listen through your speakers or headphones.
To end the call, look for a red phone icon or a button labeled "End Call" and click it. Both of you will be disconnected. If the other person does not answer within a minute or two, the call will time out and you can try again later.
Calling a regular phone number from your computer
If you want to call a cell phone or landline from your computer, you need a service that charges money. Skype Credit is one option — you buy credit in advance (usually in amounts like $5 or $10) and it deducts the cost per minute as you call. Rates vary by country, but calling a US phone number typically costs a few cents per minute.
To use Skype Credit, open Skype, go to the "Calls" tab, and look for "Call phones." Type the phone number you want to call (including the area code and country code if calling outside the US). Click the green call button. The call will connect if you have credit available. The cost appears on your screen as you talk.
Google Voice works differently — you get a free phone number, and people can call that number to reach you on your computer or phone. You can also call out from Google Voice to any US or Canada number for free, and to other countries at low rates. Sign in to Google Voice on the web, click the phone icon, type the number, and click the call button.
Troubleshooting common calling problems
If the other person cannot hear you, your microphone may be muted. Look for a microphone icon in the call window — if it has a line through it, click it to unmute. If you still cannot be heard, go to the app's settings, find the audio or microphone section, and make sure the correct microphone is selected. If you have multiple microphones (a built-in one and a USB one, for example), try switching to the other one.
If you cannot hear the other person, check that your speakers are not muted. Look for a speaker icon in the call window or on your keyboard — if it has a line through it, click it to unmute. Make sure the volume is turned up. If you are using headphones, check that they are plugged in and that the volume on the headphones themselves is turned up.
If the call keeps dropping or the audio cuts out, your internet connection may be too slow or unstable. Move closer to your Wi-Fi router, or plug in an ethernet cable if you have one. Close other programs that use the internet (like video streaming or large file downloads) while you are on the call. If the problem continues, restart your computer and try again.
If the app crashes or will not open, restart your computer. If that does not work, uninstall the app (right-click it and select "Uninstall" on Windows, or drag it to the Trash on Mac) and read it again from the official website. Make sure you are downloading from the real app store or the official website, not a third-party site.
Using a headset for better call quality
A headset with a built-in microphone gives you much better sound than your computer's built-in microphone. The microphone sits closer to your mouth, so the other person hears you more clearly. Headsets also let you move around during the call without losing audio, and they block out background noise better than a computer speaker.
Wired USB headsets plug directly into your computer and work when ready — no setup needed. Wireless headsets connect via Bluetooth and need to be paired with your computer first. To pair a Bluetooth headset on Windows, go to Settings, then Devices, then Bluetooth, and click "Add device." On Mac, go to System Preferences, then Bluetooth, and click "Set Up New Device." Follow the headset's instructions to put it in pairing mode, then select it from the list on your computer.
Once your headset is connected, open your calling app's settings and make sure the headset is selected as both the microphone and speaker. Test it by making a short call or using the app's audio test feature. You should hear yourself clearly and the other person should hear you without background noise.
Frequently Asked Questions
Do I need to pay to call someone on the same app?
No. Calling another person who uses the same app (Skype to Skype, Zoom to Zoom, WhatsApp to WhatsApp) is free as long as you both have internet. You only pay if you want to call a regular phone number or if you use a paid plan for extra features like recording or group calling.
Can someone call me on my computer if I don't give them my username?
It depends on the app. With Skype or Google Meet, they need your username or email to find you. With Google Voice, they can call your assigned phone number just like a regular phone. Check your app's settings to see if you can make your profile private or public.
What if my internet goes out during a call?
The call will drop when ready. You will need to reconnect to the internet and call them back. This is why a wired connection is better for important calls — Wi-Fi can drop more easily than an ethernet cable.
Can I record a call I make from my computer?
Most apps allow recording, but you may need to pay for a premium account or use a separate recording tool. Check your app's settings for a "Record" button during the call. Some services require the other person to agree to recording before you start.
Is calling from my computer cheaper than a cell phone plan?
For calling other computer users, yes — it is free. For calling phone numbers, it depends on your plan. Skype Credit or Google Voice rates are usually cheaper than international cell phone rates, but a regular cell phone plan may be cheaper for local calls if you make many of them.
