About
Siperb pairs a modern WebRTC softphone (Web, Windows, macOS, Linux, Android, iOS) with a hosted WebRTC-to-SIP proxy, so teams on Asterisk or FreeSWITCH get browser and mobile calling without replacing their existing PBX. Features include call recording (audio & video), blind/attended transfer, 3-way conferencing, and end-to-end encrypted media. The client UI is open source (AGPL-3.0); the hosted proxy and mobile apps are proprietary. Free Personal tier; Business (£2/user/month) and Business Pro (£5/user/month) add storage, custom integrations, and upcoming AI features.
