Most businesses already have a phone system. Siperb connects it to the modern web — so your team can make and take calls from a browser, desktop, or mobile, without replacing a thing. The short video below explains how, in about three minutes.
Our Vision
We believe the phone system a business already owns shouldn’t hold it back. Our vision is a world where any company — from a two-person team to a global enterprise — can bring its existing telephony into the browser age without tearing anything out or starting again. Modern communication should be something you switch on, not something you rebuild.
Our Mission
SIPERB’s mission is to:
- Make hard things simple: WebRTC is complex underneath. Our job is to hide that complexity so connecting a softphone takes minutes, not a specialist.
- Keep every call private: Calls are end-to-end encrypted by default, and credentials never sit in the browser. Security isn’t a feature you switch on — it’s the starting point.
- Build in the open: Siperb grew out of open-source roots, and we keep contributing to the community that made it possible.
- Actually support people: Every business, from one user to thousands, gets the tools and the help to make the switch stick.
Our Company
Siperb is a UK-registered company, built on more than fifteen years of voice-over-IP experience and the last several focused squarely on WebRTC. We’ve spent that time solving one problem properly: getting modern, browser-based calling to work with the phone systems businesses already run.
A Word from Our Founder
