Browser Phone review
A capable free browser softphone for teams running their own SIP infrastructure.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Browser Phone is a self-hosted WebRTC SIP softphone for organizations and developers operating their own PBX infrastructure. It runs in a web browser and connects with Asterisk, FreeSWITCH, or another SIP-based PBX. The feature set covers SIP audio and video calling, blind and attended transfers, three-party conferences, call recording, call detail records, messaging, contact management, and screen sharing. It is a focused option for browser-based deployments rather than a multi-platform communications suite.
The published offering is free and open source, with a self-hosted web application and an AGPL-3.0 licensed repository. Docker deployment is supported, which gives teams a defined path for running the application as a standalone web service. There are no paid tiers to compare, so the main consideration is operational ownership: teams need to provide and maintain the hosting environment and connect Browser Phone to their SIP infrastructure. That model suits organizations with technical resources and an existing PBX, while teams seeking a hosted service may prefer a different type of softphone product.
Browser Phone’s strongest fit is its browser-centered calling depth. Alongside audio and video calls, it includes transfers, conferencing, recording, call detail records, SIP and XMPP messaging, buddy and contact management, and in-call screen sharing. Its ecosystem fit is similarly clear: Asterisk, FreeSWITCH, and SIP-based PBXs are named integration targets. The trade-off is platform breadth. With web access only and no mobile or desktop application, it is less suitable for users who need native applications or calling outside a browser. Pick it for a free, self-hosted browser softphone tied to an existing SIP environment; look elsewhere for broader client coverage or hosted operations.
