WebRTC for Business: No Phone System Needed
Technology · 2026-03-31 · 5 min read
What is WebRTC?
WebRTC (Web Real-Time Communication) is an open-source technology built into every modern browser — Chrome, Firefox, Safari, Edge. It enables real-time audio, video, and data communication directly between browsers, without plugins or downloads. Google Meet, Discord, and Facebook Messenger all use WebRTC. It is not experimental technology — it handles billions of minutes of communication every day.
Why businesses still use phone systems
Most businesses use phone systems out of inertia, not necessity. Traditional PBX systems were the only option for decades. Cloud VoIP (Aircall, RingCentral, Twilio) modernized the delivery but kept the same model: phone numbers, per-minute charges, IVR menus, and hardware headsets. For businesses whose customers primarily interact through their website, this model is expensive overkill.
The browser-to-browser alternative
WebRTC enables a fundamentally different approach: browser-to-browser calling. A visitor on your website clicks a button and connects to your team's browser dashboard. No phone number is dialed. No PSTN (public telephone network) is involved. The audio travels over the internet, encrypted end-to-end, at zero per-minute cost. Your team answers from Chrome, Firefox, or Safari — no desk phone, no softphone app, no VoIP provider.
Security: enterprise-grade by default
WebRTC mandates encryption. Every call uses DTLS-SRTP, meaning audio is encrypted in transit with no option to disable it. This is actually more secure than many traditional phone systems, where calls traverse the PSTN unencrypted. For businesses handling sensitive information (healthcare, legal, financial services), WebRTC's mandatory encryption is a significant advantage.
Cost comparison
Traditional phone system: $30-50/user/month + per-minute charges + hardware. Cloud VoIP: $20-40/user/month + per-minute charges for outbound. WebRTC-based (WebCallHub): Starter plan first month free, then $19/month for 2 agents with 300 min/month. Growth plan from $49/month for up to 5 agents and 2,500 min/month. Business plan $149/month for up to 15 agents and 5,000 min/month. All prices in USD. For a team handling 1,000 inbound minutes per month, the cost difference versus cloud telephony can be dramatic.
Limitations of WebRTC for business
WebRTC is not a replacement for all phone use cases. You still need a traditional phone system for: outbound cold calling, receiving calls from people who dial a phone number, regulatory requirements for a published business phone number. WebRTC is ideal for: inbound website calls, customer support, sales conversations with website visitors, and any scenario where the customer journey starts on your website.
