Browser-based calling, explained

Phone numbers are friction on the web

A phone number on a website forces a context switch: the visitor leaves your page, dials on another device, waits in a queue, and repeats everything the page already told you. International visitors pay long-distance rates or don't call at all. And on the business side you're paying per-minute telecom fees for what is, in 2026, just audio data.

The call happens where the customer already is: the browser

WebCallHub uses WebRTC — the real-time audio technology built into Chrome, Safari, Firefox, and Edge — to connect the visitor's browser to your agent's browser through an encrypted media server. Click, allow microphone, talk. Typical connection time is under 10 seconds from click to conversation.

Nothing to install, ever

Visitors need zero downloads and zero accounts. Agents answer from a browser dashboard or an optional Windows/macOS desktop app.

Works worldwide at flat cost

A visitor in Tokyo calling your team in Helsinki costs the same as one next door: nothing per minute. No international tariffs, no phone bill.

Encrypted by default

DTLS-SRTP encryption in transit on every call — stronger than a standard PSTN phone call, which is not encrypted at all.

More than a call

The same widget carries live chat, booking pages, QR-code calling, IVR routing, recording, and AI transcription — one platform instead of five tools.

Where browser calling replaces the phone

• Customer support — visitors call from the page where the problem happened
• Sales — pricing-page visitors reach a human while intent is highest
• Telehealth — patients join consultations without installing anything
• International businesses — one call button serves every country at no per-minute cost
• Privacy-conscious teams — agents take calls without exposing personal phone numbers

Frequently asked questions

What is browser-based calling?

Browser-based calling is a voice conversation carried entirely by web browsers using WebRTC, the real-time communication standard built into Chrome, Safari, Firefox, and Edge. Instead of dialing a phone number, a visitor clicks a call button on a website and speaks through their device's microphone; the other party answers in a browser dashboard. No phone line, SIM, or app is involved.

Do calls use my phone line or minutes?

No. Audio travels over the internet as encrypted data, like a video meeting. There is no PSTN involvement, so there are no per-minute charges, no phone bill, and no phone number required on either side.

What do I need to add it to my website?

One JavaScript snippet. Paste it into any site — WordPress, Shopify, Webflow, Wix, Squarespace, or custom code — and the call widget appears. Your team answers at webcallhub.com/app/support. Setup takes about 5 minutes.

What does browser-based calling cost?

WebCallHub's Free plan is $0 forever: 1 agent, 1 website, 200 call minutes/month. Paid plans start at $19/month (Starter) and add agents, websites, unlimited calls, AI features, and analytics up to Business at $149/month.

Is call quality as good as a phone call?

Usually better. WebRTC uses the Opus codec, which carries roughly double the audio frequency range of a traditional phone line, with echo cancellation and noise suppression built in. Quality depends on the internet connection; the platform adapts bitrate automatically.

What happens if no agent is available?

You choose: route to an AI voice agent that answers, qualifies, and takes a message; show a booking page so the visitor schedules a callback; or display offline hours. Missed calls become follow-ups instead of lost leads.
