About this app
FreeSBC is an open-source SIP and WebRTC edge proxy designed with simplicity in mind, featuring a single static binary and YAML configuration file. It provides zero external dependencies, acting as a secure boundary between public networks and private switches like Asterisk or FreeSWITCH. It handles trunk B2BUA, edge proxy, RTP/SRTP relay, WebRTC gateway, and built-in SIP security with an embedded WebUI, REST API, and Prometheus metrics.
