OpenSIPS vs Red5: at a glance
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.
What is Red5?
Red5 2.2.0 makes JDK 25 the minimum after a run of thinly documented patches.
Red5 is a Java media server built around RTMP. Red5 Server 2.2.0 made JDK 25 the baseline, cleaned removed JVM flags out of the launch scripts and fixed service setup, after 2.0.49 made the AMF0 and AMF3 codecs spec-compliant. Tags such as 2.0.53 continue alongside it with no notes beyond a changelog link.

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.
Red5
5.0MEETINGS
Red5 2.2.0 makes JDK 25 the minimum after a run of thinly documented patches.
◆ Current state
Red5 is a Java media server built around RTMP. Red5 Server 2.2.0 made JDK 25 the baseline, cleaned removed JVM flags out of the launch scripts and fixed service setup, after 2.0.49 made the AMF0 and AMF3 codecs spec-compliant. Tags such as 2.0.53 continue alongside it with no notes beyond a changelog link.
◆ Where it's heading
After the patch run, Red5 is modernizing its runtime and packaging rather than adding media features. The servlet module is back in the build but not yet shipped, so finishing that packaging is the visible open item.
◆ Prediction
A 2.2.x follow-up that packages the servlet module (restoring RTMPT) and fixes service installs on JDK 25 is likely, since the 2.2.0 notes name both as known issues.
