What is Kamailio?

Kamailio's feed shows quiet, migration-free upkeep across two stable branches.

Kamailio is a mature open-source SIP server, and its tracked releases are maintenance drops: v6.1.5 on the current 6.1 stable branch and, earlier, v5.8.7 on 5.8. Both carry fixes only, with no database schema or configuration language changes, and the project strongly recommends upgrading within each branch.

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.

Kamailio vs Red5: editorial side-by-side

K
Kamailio
MEETINGS
2.5

Kamailio's feed shows quiet, migration-free upkeep across two stable branches.

◆ Current state

Kamailio is a mature open-source SIP server, and its tracked releases are maintenance drops: v6.1.5 on the current 6.1 stable branch and, earlier, v5.8.7 on 5.8. Both carry fixes only, with no database schema or configuration language changes, and the project strongly recommends upgrading within each branch.

◆ Where it's heading

The visible pattern is conservative branch upkeep: fixes land on more than one branch at once without forcing operators to touch configs or schemas. The feed does not show feature releases or capability shifts.

◆ Prediction

Expect further 6.1.x point releases on the same no-migration terms; the entries do not show when the next feature branch is due.

R
Red5
MEETINGS
5.0

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.
