WebRTC Browser Calling: Make Calls Straight From Your Browser

In short

WebRTC browser calling lets you place real phone calls from a web browser tab, with no app to install and no SIM card. StartACall uses this technology so you can dial from Chrome, Safari, Edge, or Firefox and talk over an end to end encrypted connection, paying per minute as you go.

What WebRTC browser calling actually means

WebRTC is the open standard that lets browsers send and receive audio in real time without a plugin. StartACall builds on it so the call runs inside the same tab you already have open. You grant microphone access once, dial the number, and the audio streams directly through the browser, which means there is nothing to download and nothing to sideload onto your phone.

Because the call lives in the browser, it works the same on a laptop, a Chromebook, or a phone screen. You do not need a phone number of your own to place outbound calls, and you do not need a SIM card, so a borrowed or work computer is enough to get connected.

Browser support and what you need

StartACall works in current versions of Chrome, Safari, Edge, and Firefox, the four browsers that carry mature WebRTC support. All you really need is a stable internet connection, a microphone, and permission for the site to use it. There is no install step and no account tied to a physical device.

Pricing and receiving calls

Outbound calling is pay as you go, billed per minute, with no monthly plan and no number required. This keeps it practical for occasional international calls or short bursts of business calling without a contract.

If you want people to call you back, you can add a dedicated US or Canada digital number for a monthly fee between $2.14 and $5. That number rings inside the same browser session, so inbound and outbound both stay in one place, and every call is end to end encrypted.

Frequently asked questions

Do I need to download an app to use WebRTC browser calling?+

No. The call runs entirely inside your web browser. You only grant microphone access once, then dial. There is no app, no extension, and no SIM card needed.

Which browsers can I make WebRTC calls in?+

StartACall works in current versions of Chrome, Safari, Edge, and Firefox. Any of these with a working microphone and an internet connection is enough to place a call.

Are browser calls encrypted?+

Yes. Calls use end to end encryption, which makes browser calling a strong fit for private conversations, international calls, and business use.

Can I receive calls in the browser too?+

Yes, but you need to add a digital phone number first. A US or Canada number costs as little as $2.14 and at most about $5 per month and lets inbound calls ring in the same browser session. Outbound calls need no number at all.
