Your browser is the phone now. Build voice into it.
Vobiz WebRTC turns any browser or mobile app into a voice endpoint. No softphone, no hardware, no friction for your end users. Built for AI voice interfaces, contact center agent desks, and voice-enabled SaaS products.
Capabilities
Every voice capability your browser or app needs.
Browser-native calling, AI-ready audio, and full call control — backed by managed WebRTC infrastructure.
No STUN/TURN setup, no codec negotiation, no signaling servers to run yourself.
Browser Calling
Make and receive calls directly from a browser tab or app. Vobiz bridges the browser session to the PSTN across 190+ countries — for both outbound and inbound. Inbound calls to WebRTC endpoints can be queued via API for managed routing to available agents.
AI-Native Audio
High-definition 24kHz audio with barge-in detection built into the media layer. Your AI agent hears clearly and responds at the right moment — even in noisy environments.
Real-Time Audio Streaming
Stream live call audio from a browser session over secure WebSockets at ~80ms end-to-end. Low-latency audio delivery for any real-time processing pipeline connected to the call.
Full Call Control
Mute, hold, transfer, or bridge any WebRTC call from your server using the same call control primitives as the Vobiz Voice API. Control is not limited to the browser client.
Managed Infrastructure
Get browser-native voice without building or maintaining the infrastructure behind it. Vobiz handles STUN/TURN servers, NAT traversal, codec negotiation, and signaling.
Call Recording
Record any WebRTC call on demand. Agent and caller audio stored separately by default, encrypted, and retrievable via the Recordings API — for compliance, quality review, or training.
Call Insights
Access real-time and historical call data for every WebRTC session. Track call duration, completion rates, and performance metrics directly from the Vobiz dashboard.
Why Vobiz
Why teams build browser voice on Vobiz.
Unified Stack
One stack for browser, mobile, and PSTN.
Vobiz WebRTC connects to the same number provisioning, SIP trunking, and Voice API infrastructure. Teams get a unified platform — not separate products to integrate and maintain. Browser, mobile, and PSTN all run on the same stack from day one.
In-Product
Voice that stays inside your product.
A support widget, an onboarding flow, a checkout confirmation, a product demo — these are moments where taking users to a phone call breaks the experience. Vobiz WebRTC keeps voice inside the product, at every touchpoint where leaving would cost you the interaction.
How It Works
Browser to live call in minutes.
Integrate the SDK.
Add the Vobiz WebRTC SDK to your web or mobile app. Configure your credentials and initialise the client.
Register your endpoint.
Make and receive calls.
WebRTC infrastructure included. The Vobiz WebRTC SDK connects your browser or mobile app to Vobiz's voice infrastructure. Vobiz handles STUN/TURN servers, codec translation between Opus and G.711, and PSTN bridging.
Use Cases
What teams build with Vobiz WebRTC.
Contact center agent desktop
Agents make and receive calls directly in a browser tab. No SIP softphone, no hardware phone, no desktop app installation required. Works from any device with a browser and an internet connection.
Embedded click-to-call
Add a call button anywhere in your SaaS product. Users connect to a human agent or AI agent without leaving the application. One click, live call.
