CloudSIP – Open Source WebRTC SIP Phone and Browser Extension for Asterisk

Hello Asterisk Community,

I would like to introduce CloudSIP, an open-source WebRTC SIP client developed for organizations and service providers looking for a modern browser-based telephony experience.

CloudSIP.app enables users to make and receive SIP calls directly from a web browser using WebRTC technology, eliminating the need for traditional desktop softphones while maintaining compatibility with Asterisk deployments.

Key Features

  • WebRTC audio calling
  • SIP over Secure WebSocket (WSS)
  • Incoming and outgoing calls
  • Call history
  • Hold, Mute, Transfer
  • DTMF support
  • Responsive user interface
  • Easy integration with existing platforms
