How Does a Phone Call From a Computer Work?
A call from a computer works by converting your voice into small data packets, sending them over the internet to a provider, and having that provider hand the call to the regular phone network so the other person's phone rings. This technology is called VoIP, voice over internet protocol, and it is what powers every option in this guide.
There are three common set-ups. In the first, the computer borrows your phone: the PC or Mac talks to your handset over Bluetooth or Wi-Fi, and the call actually runs through your mobile plan. In the second, an app-to-app service such as WhatsApp carries the call over the internet between two people who both use that app. In the third, a VoIP provider gives you a number and an app or browser dialer; calls to ordinary phones leave the provider's network and complete over the public phone network.
Browser calling is a variation of the third set-up. Modern browsers include a technology called WebRTC that handles audio directly, so a web page can behave like a phone with nothing to install. Chrome, Edge, Firefox and Safari all support it, which is why a cloud phone's web dialer works on a Chromebook as readily as on a Windows desktop. Older "softphone" apps do the same job as installed software.
What Do You Need to Make a Phone Call From a Computer?
The requirements are modest. Most problems people report with computer calling come from one of the items below being missing or misconfigured.
- A microphone and speakers: A built-in laptop microphone works, but a USB or Bluetooth headset keeps your voice clear and prevents echo. A Mac mini or Mac Studio has no built-in microphone.
- A stable internet connection: Voice needs very little bandwidth, roughly 100 kbps in each direction per call, but it needs a steady link. A wired Ethernet connection or a strong Wi-Fi signal is better than a congested café network. If audio keeps breaking up, the guide on how much bandwidth VoIP needs shows what a team of several callers requires.
- A calling app or service: This is the piece that places the call. It could be a free tool that rides on your phone, an app-to-app service or a paid VoIP account.
- A number to call from: When you call a regular phone, the person sees a caller ID. With Phone Link or FaceTime it is your mobile number. With a VoIP provider it is a virtual phone number assigned to your account, which can be local to the area you serve.
- A modern browser or a supported operating system: Phone Link needs Windows with a paired Android or iPhone. Calls on Mac need an iPhone signed into the same Apple Account. Browser dialers need a current version of Chrome, Edge, Firefox or Safari.
How Do You Make a Phone Call From a Windows or Mac Computer?
The steps differ slightly by platform, but all of them follow the same pattern: set up once, then dial like any phone. Use the version that matches how you want your calls to appear.
Windows
On Windows, the quickest route that uses your own number is Microsoft's Phone Link. Windows also supports every VoIP app and browser dialer in this guide.
Step 1: Open Phone Link from the Start menu, or install it from the Microsoft Store if it is missing.
Step 2: Pair your phone. On Android, install the Link to Windows app and scan the QR code shown on the PC. On iPhone, pair over Bluetooth.
Step 3: Allow Phone Link to access your calls and contacts when prompted.
Step 4: Open the Calls tab, type a number or search your contacts, and click the call button.
Mac
A Mac can place calls through an iPhone, which stays on and nearby. Apple lists the main conditions: the Mac and iPhone are signed into the same Apple Account, both are on the same network, and Calls on Other Devices is enabled on the iPhone.
Step 1: On the iPhone, open Settings, go to Phone, choose Calls on Other Devices and allow your Mac.
Step 2: On the Mac, open FaceTime, go to its settings and turn on Calls from iPhone.
Step 3: Click any phone number in Contacts, Calendar, Messages or Safari, or open FaceTime and type the number.
Step 4: Confirm the call prompt and speak through the Mac's microphone and speakers.
Any browser, with no install
If you do not want to pair a phone or install software, a VoIP account gives you a web dialer. This is the same route used on Chromebooks and shared office computers.
Step 1: Sign in to your VoIP provider's web app in Chrome, Edge, Firefox or Safari.
Step 2: When the browser asks for microphone permission, choose Allow. If you blocked it earlier, click the padlock icon in the address bar and re-enable it.
Step 3: Open the dial pad, type the number with the country code (for example +1 for the US and Canada), and check your caller ID.
Step 4: Click call. Use mute and hold from the same screen, and end the call with the hang-up button.
Many providers also offer a Chrome extension that turns phone numbers on web pages into click-to-call links, which saves retyping numbers from a CRM or a website. Providers that include one are covered in the guide to VoIP providers with browser extensions.
How Do the Best Ways to Call From a Computer Compare?
The eight options below fall into three groups: free tools that borrow your phone or run app to app, personal and small-team numbers, and full business phone systems. Choose by whether you need your own number, how many people will call, and whether you need features such as recording and routing.
| Tool | Type | Works without your phone nearby | Calls regular phone numbers | Starting price (checked Oct 2026) |
|---|---|---|---|---|

How We Compared These Tools
We checked each vendor's own product, support and pricing pages in October 2026, read the steps and requirements as the vendor publishes them, and compared what each tool needs, whether it works away from your phone, who it fits and how it charges. We did not use review-site ratings for these tools, so no star scores are quoted. Plans, promotions and taxes change often, so confirm current prices on each vendor's site before you buy.
Zoom's own pricing page could not be loaded during our check, so its figures come from a third-party summary and are marked as such. Phone Link and WhatsApp support pages were not retrievable either, so their steps are based on the vendors' published set-up flows as described by independent how-to guides and should be confirmed in the apps.
What Are the Best Apps and Tools to Call From a Computer?
Each entry below explains what the tool is, how it places a call and where it stops being a fit, followed by its main features and pricing.
1. Microsoft Phone Link
Phone Link is a Windows app that connects an Android phone or iPhone to a PC so you can see messages, notifications and calls on the larger screen. Calls are not VoIP: the PC acts as a remote control and speaker for the handset, so the call runs through your mobile carrier and shows your own number. That makes it the simplest way to avoid fiddling with a second number.
The trade-off is that the phone has to be close. Phone Link uses Bluetooth for calls, so the handset must stay within roughly 10 meters with Bluetooth switched on, and iPhone pairing involves extra steps and a few feature differences compared with Android. It is a personal convenience, not a team phone system, so there is no call routing, shared inbox or recording.
Key features
- Place and receive calls from the Windows Calls tab with your own mobile number
- Search contacts and view recent calls on the PC
- Send and read text messages and notifications from the same window
- Pairs with Android through the Link to Windows app and with iPhone over Bluetooth
Pricing: No separate charge for the app. Calls use your existing mobile plan, so minutes and roaming charges follow your carrier.
2. FaceTime and iPhone Calls on Mac
Apple lets a Mac place and receive ordinary phone calls through a nearby iPhone, using the same Apple Account on both devices. You can click a phone number in Contacts, Calendar, Messages or Safari, or open FaceTime and dial, and the Mac's speakers and microphone take over while the call runs through the iPhone's carrier connection. On newer macOS releases there is also a Phone app that does the same job.
Apple's requirements are specific: an iPhone running iOS 8.1 or later with an active plan, a Mac on OS X Yosemite 10.10 or later, both signed in to the same Apple Account, both on the same network, and Calls on Other Devices enabled on the iPhone. If the iPhone is off or out of range the call cannot be placed, and it is built for one person rather than a team.
Key features
- Click-to-call from Contacts, Calendar, Messages and Safari
- Uses your own iPhone number as caller ID
- Works with FaceTime audio and video to other Apple users
- Also available on iPad
Pricing: No separate charge from Apple. Standard calls draw on your iPhone plan, and an external microphone is needed on a Mac mini, Mac Studio or Mac Pro.
3. Google Voice
Google Voice gives you a number that rings in a web browser and in a mobile app. Individuals in the US can use it free, with a US number and calls placed from voice.google.com; creating a new number requires a US account and US verification, according to independent guides, and calls to numbers outside the US and Canada cost per-minute fees. Because it runs in the cloud, your computer does not need your phone close by.
For teams, Google Voice sits inside Google Workspace with three paid tiers. Starter supports up to 10 users, while Standard and Premier add unlimited users, ring groups, a multi-level auto-attendant, desk phone support and call recording (ad hoc on Standard, automatic on Premier). Google's page lists calls to the US, Canada and most European countries as included on all plans. Text messaging is built for conversations, not bulk sending, and bulk or link-heavy messages can trigger temporary blocks. If you outgrow it, Google Voice alternatives cover other options.
Key features
- Browser and mobile calling with a US number
- Voicemail transcription, call forwarding and spam filtering
- Workspace tiers with ring groups, auto-attendant and recording
- Calendar and Meet integration on paid plans
Pricing: Personal use is free in the US. Workspace plans on Google's page: Starter $10, Standard $16 (also shown alongside $20) and Premier $24 (also shown alongside $30) per user per month. The page does not state the billing basis for each figure.
4. WhatsApp Desktop
WhatsApp Desktop is an app for Windows and Mac that links to your phone account by scanning a QR code under Linked Devices. From a contact's chat you click the phone or video icon to call. The call goes over the internet to the other person's WhatsApp, which is why it uses data rather than carrier minutes and why international calls between WhatsApp users carry no per-minute fee.
The limit is that both people need WhatsApp, so it cannot dial a landline or a customer who is not on the app, and the number shown is your personal one. It suits friends, family and informal contacts abroad rather than business use, where customers expect a proper caller ID, voicemail and records.
Key features
- Voice and video calls between WhatsApp users
- Linked-device sign-in with a QR code
- Calls use internet data, not carrier minutes
- Messages and files in the same window
Pricing: No charge between WhatsApp users, aside from your own internet or mobile data costs.
5. Dialpad
Dialpad is a cloud communications platform with a desktop app, mobile apps and a browser version. To call, you open the app or sign in on the web, click the phone icon, type a number or search a name, and press dial; you can also start a call from inside a chat. Its Connect line is the general business phone product, while the Sell and Support lines are aimed at sales and contact center teams.
Dialpad's help material describes a local number included in paid plans, optional texting, video calls, call recording and real-time transcription, with local numbers offered in more than 50 countries. Some features, such as advanced analytics and AI tools, sit on higher tiers, so check which plan holds the feature you want.
Key features
- Desktop, mobile and browser calling
- Search by name, email, company or number, or call from a chat
- Optional SMS/MMS, call recording and live transcription
- Sales and support products with dialing and routing tools
Pricing: Connect Standard $15 and Connect Pro $25 per user per month on Dialpad's pricing page (the page has a monthly and annual toggle but shows a single figure, and notes annual plans include a discount). Sell Essentials is $39 and Support Essentials $89. Enterprise is by quote.
6. Zoom Phone
Zoom Phone adds a business phone line to the Zoom app that many teams already use. After a Zoom Phone license is enabled for your account, you open Zoom on desktop or mobile, check your connection and audio settings, open the Phone tab, enter a number or pick a contact and click the call icon. It shares one app with meetings, chat and voicemail.
It fits organizations already standardized on Zoom, because users, meetings and phone sit together. Calling plans come in metered and unlimited versions for US and Canada, with bundles that add video and AI features, and extras such as international calling and additional numbers are priced separately.
Key features
- Calls from the Zoom desktop or mobile app
- Voicemail, call recording, call history and CRM integration
- Unified with Zoom meetings and team chat
- Metered or unlimited regional calling plans
Pricing: We could not load Zoom's own pricing page. Third-party summaries, updated in July 2026, report US and Canada Metered at about $10.50 and Unlimited at $16 per user per month billed annually, with higher bundles above that. Treat these figures as unconfirmed and check Zoom directly.
7. Vonage Business Communications
Vonage Business Communications, often shortened to VBC, is a cloud phone system with a desktop app for Windows and Mac, a mobile app and a web version. To call, you open the app, choose New Call, pick someone from your directory or open the keypad and type a number. Afterwards you can review call history and follow up by message.
Plans are tiered. Mobile covers apps, unlimited domestic calling, SMS and MMS and voicemail. Premium adds VoIP desk phone support, video meetings for up to 200 participants, team messaging, an app marketplace with more than 20 integrations and single sign-on. Advanced adds 15 hours per month of on-demand call recording, visual voicemail with transcription and call groups. Annual plans require a one-year contract for new accounts.
Key features
- Desktop, mobile and browser apps
- Unlimited domestic calling on all three plans
- Integrations with CRM tools, Microsoft Teams and Slack
- Virtual receptionist, extensions and call groups
Pricing: Per user per month, monthly billing: Mobile $14.99 to $19.99, Premium $24.99 to $29.99, Advanced $34.99 to $39.99. With the annual 30% promotion listed through December 31, 2026: $10.49 to $13.99, $17.49 to $20.99 and $24.49 to $27.99. Prices fall as team size grows, and taxes and fees are extra.
8. Calilio
Calilio is a cloud business phone system for VoIP calls, SMS and virtual numbers. You can call from its web phone in a browser, use it with the Chrome extension for click-to-call, and work from the same shared workspace as the rest of your team. Calls leave from a Calilio virtual number, so customers see a business caller ID rather than a personal mobile.
Beyond the dialer, Calilio includes call forwarding, IVR menus, business hours, ring groups with simultaneous, sequential and round-robin ringing, a call queue, call recording, voicemail transcription, notes and tags, and a power dialer for outbound campaigns. It connects with Pipedrive, HubSpot, Zoho CRM, Salesforce and Pabbly Connect, and supports number porting for teams that want to keep an existing number.
Key features
- Web phone and Chrome extension with click-to-call
- Shared numbers, call transfer, call flip and forward chat
- IVR, business hours, call queue and multiple ring strategies
- Call recording, AI call reports and sentiment analysis, live listen, whisper and barge
- Calilio Hub prepaid calling, SMS and combo packs for specific countries, in a range of sizes and validity periods
Pricing: Standard is $15 per user per month, or $12 billed annually, and Premium is $35, or $28 billed annually. Every plan includes a free local number in the US, Canada or UK and a monthly bundle of free minutes and SMS that applies to US and Canada calls and texts. After the allowance, usage is billed from a wallet. See the Calilio pricing page.
How Do You Choose the Right Way to Call From a Computer?
Start with who the caller is and what the other person should see. The right tool for ringing a relative is not the right tool for a customer-facing line.
- Personal calls with your own number: Phone Link on Windows or iPhone calls on Mac keep your normal caller ID and cost nothing extra, as long as your phone is close.
- Calls to friends abroad: WhatsApp Desktop is the lowest-friction choice when both people already use it, and international calling from the USA to everyone else is worth pricing per minute first.
- A separate line for work: Google Voice suits individuals and tiny teams, while a business VoIP service fits when several people share numbers and need routing, recording and CRM links.
- Security and compliance: Business calls should use encrypted voice and two-factor sign-in, as outlined in the overview of VoIP security and encryption. Recording laws differ by state and country, so get consent where required; this is general information, not legal advice.
How Do You Fix Poor Audio When Calling From a Computer?
Most call problems come from a few causes, and each has a quick fix. Work through them in order before blaming the app.
- Choppy or robotic voice: This is usually a weak connection. Move closer to the router, use Ethernet and pause large downloads. One-way delay under about 150 ms and packet loss under 1 percent keep calls natural, as explained in the guide to VoIP call quality.
- Echo or feedback: Use a headset or lower the speaker volume, because echo is usually the other person's voice leaking from your speakers back into your microphone.
- No sound or a blocked microphone: Check browser and operating system permissions, then confirm the right input and output device in the app's audio settings.
- Firewall or VPN problems: Some firewalls and VPNs block the ports voice uses, so ask your IT team to allow VoIP and WebRTC traffic. You can also run Calilio's VoIP test to check your connection before an important call.
Next step
Ready to Get Started?
Calling from a computer comes down to how much you need beyond a dial pad. If you only want to use your own number, Phone Link on Windows or iPhone calls on Mac do the job. If you need a separate number, a team or business features, a VoIP service with a web phone is the better route, and the plan comparison above shows how the main options charge.
Calilio is a cloud business phone system with a web phone, Chrome extension, call routing and recording; every plan includes a free local number in the US, Canada or UK and a monthly bundle of free minutes and SMS.
Frequently Asked Questions
Can I make a phone call from my computer for free?
Yes, in limited ways. Phone Link and iPhone calls on Mac cost nothing extra but use your mobile plan, Google Voice offers free personal calling to US and Canadian numbers from a US account, and WhatsApp is free between WhatsApp users. Calling an ordinary phone number from a VoIP business service normally needs a paid plan or prepaid credit.
Do I need to download anything to call from my browser?
No. A VoIP provider's web phone runs in Chrome, Edge, Firefox or Safari using WebRTC, so you only sign in and allow the microphone. A downloaded desktop app is optional and sometimes adds headset controls or notifications.
Can I call a landline or mobile number from my computer?
Yes. Phone Link, iPhone calls on Mac, Google Voice and business VoIP apps can all call regular landline and mobile numbers. WhatsApp cannot, because it only connects people who both use WhatsApp.
Do I need a headset or microphone?
You need some microphone and speaker. A built-in laptop microphone works for casual use, but a headset gives clearer audio and prevents echo, and a Mac mini, Mac Studio or Mac Pro needs an external microphone.
How does a computer call differ from a normal phone call?
A normal call travels over a carrier's circuit, while a computer call is sent as internet data and handed to the phone network at the end. To the person you call it looks the same, but the caller ID shows either your own mobile number or the virtual number your provider assigned.
Can I make international calls from a computer?
Yes. App-to-app tools like WhatsApp carry calls free between users, and VoIP services call international numbers at per-minute rates that are usually lower than mobile carrier rates. Prepaid packs for specific countries, such as those in Calilio Hub, can lower rates further for frequent destinations.
How much internet speed do I need to call from a computer?
About 100 kbps in each direction per call, so almost any broadband or good mobile connection is enough. Stability matters more than speed: aim for low delay, under 1 percent packet loss and little jitter.
Is calling from a browser safe?
It can be, provided the provider encrypts voice traffic and protects logins. Use a trusted VoIP service, enable two-factor sign-in where offered, keep the browser updated and avoid sensitive calls on open public networks.
