Element Call vs OpenSIPS
A side-by-side editorial comparison of Element Call and OpenSIPS — release velocity, themes, recent moves, and the top alternatives to consider.
Element Call vs OpenSIPS: at a glance
What is Element Call?
Element Call starts moving to new LiveKit transports and falls back to remote SFUs when needed.
Element Call ships a release candidate roughly every two to three weeks. v0.28.1-rc.1 adds a breaking change that falls back to publishing media on a remote SFU when possible, supports migrating to new LiveKit transport types and endpoints, and fixes room v12 power-level compatibility. It also brings in a MatrixRTC SDK and patches several dependency security advisories. The previous rc added a quick audio menu and redacted analytics IDs from rageshakes.
What is 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.

Element Call
5.0MEETINGS
Element Call starts moving to new LiveKit transports and falls back to remote SFUs when needed.
◆ Current state
Element Call ships a release candidate roughly every two to three weeks. v0.28.1-rc.1 adds a breaking change that falls back to publishing media on a remote SFU when possible, supports migrating to new LiveKit transport types and endpoints, and fixes room v12 power-level compatibility. It also brings in a MatrixRTC SDK and patches several dependency security advisories. The previous rc added a quick audio menu and redacted analytics IDs from rageshakes.
◆ Where it's heading
With the MatrixRTC protocol cutover finished in August, the team is now working on the media transport layer itself: how calls find and publish to SFUs and how LiveKit endpoints change underneath them. Packaging the RTC logic as an SDK suggests it is meant to be reused beyond the Element Call app.
◆ Prediction
Expect a 0.28.1 final and follow-ups to the LiveKit transport migration; whether the MatrixRTC SDK gets its own release isn't clear from the entries.
OpenSIPS
0.0MEETINGS
OpenSIPS 4.0 is in release-candidate testing, with two RCs a month apart.
◆ Current state
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.
◆ Where it's heading
The product is moving toward a 4.0 major release through a standard RC cycle. A second RC a month after the first suggests stabilization work rather than new scope, but the entries do not say what 4.0 changes.
◆ Prediction
A 4.0.0 general release is the next expected step; what it contains cannot be read from these announcements.
