Kamailio vs rtpengine: at a glance
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 rtpengine?
rtpengine opens the mr26.3 branch with a rollback message and leaner call state.
Sipwise's rtpengine media proxy opened a new mr26.3 branch on October 19. Its first build, mr26.3.1.1, carries everything from mr26.2.1.5 plus a rollback NG control message, relaxed loop detection for duplicate packets arriving over a second apart or from endpoints no longer local, ICE agent teardown when a peer drops ICE, inject-audio mixing fixes, and a long run of "lightweight string" refactors across call IDs, tags, SDP and recording fields. Three days earlier, a hardening batch went to four branches, followed by compile-fix releases.

Kamailio
2.5MEETINGS
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.
rtpengine
5.0MEETINGS
rtpengine opens the mr26.3 branch with a rollback message and leaner call state.
◆ Current state
Sipwise's rtpengine media proxy opened a new mr26.3 branch on October 19. Its first build, mr26.3.1.1, carries everything from mr26.2.1.5 plus a rollback NG control message, relaxed loop detection for duplicate packets arriving over a second apart or from endpoints no longer local, ICE agent teardown when a peer drops ICE, inject-audio mixing fixes, and a long run of "lightweight string" refactors across call IDs, tags, SDP and recording fields. Three days earlier, a hardening batch went to four branches, followed by compile-fix releases.
◆ Where it's heading
Development continues on two levels: correctness fixes backported across every supported branch, and newer work, such as the rollback message and memory-lighter call state, landing on the newest line. Opening mr26.3 adds a fifth maintained branch, so the backport load grows.
◆ Prediction
Expect mr26.3.1.x point builds and continued synchronized backports to mr12.5 through mr26.2. The entries don't show when older branches stop receiving fixes.
