WebRTC Calling API

Enable in-browser voice calling with our WebRTC Calling API backed by the SVB network.

Build an integrated experience with
in-browser calling

SVB’s WebRTC Calling API (Web Real-Time Communication) enables you to quickly add voice calling to your web-based applications without the need for any telecom infrastructure.

Seamless in-browser calling and PSTN connectivity

To truly power voice calling in your web application, you need flexible SDKs that deliver SIP and PSTN connectivity. Our WebRTC Calling API allows you to integrate both, eliminating the need for complex, expensive telecom server components.
