About OpenSIPS

OpenSIPS 4.0 is in release-candidate testing, with two RCs a month apart.

OpenSIPS, the open-source SIP proxy and server, has two tracked entries: 4.0.0-rc1 in May and 4.0.0-rc2 in June 2026. Both release notes are one-line announcements, so the specific 4.0 changes are not visible in the feed.
