Open Source Browser Extension & WebRTC SIP Phone for FreePBX

Hello everyone,

I’d like to share an open-source project I’ve been working on that may be useful for FreePBX, Asterisk, and SIP users.

CloudSIP.app is a WebRTC SIP Phone available both as a standalone web application and as a browser extension. It is designed to work with FreePBX, Asterisk, and other SIP-compatible platforms supporting WebRTC/WSS.

Features

  • SIP over WebSocket (WSS)
  • WebRTC audio calling
  • Browser Extension for Chrome/Edge
  • Standalone Web Phone
  • Call history
  • Mute, Hold, Transfer
  • DTMF support
  • Presence and registration status
  • Lightweight and easy deployment
  • Self-hosted or cloud-hosted

Browser Extension Repository

GitHub:

The extension allows users to make and receive calls directly from their browser without requiring a separate desktop softphone.

Web Phone Repository

GitHub:

The web version can be integrated into existing portals, CRMs, PBX systems, and customer platforms.

Typical Use Cases

  • FreePBX deployments
  • Asterisk-based PBX systems
  • Call centers
  • CRM click-to-call integrations
  • Remote and hybrid teams
  • Multi-tenant VoIP providers

Feedback Welcome

The project is actively being developed and I’d appreciate any feedback, testing results, feature requests, or contributions from the community.
