Asterisk vs rtpengine
A side-by-side editorial comparison of Asterisk and rtpengine — release velocity, themes, recent moves, and the top alternatives to consider.
Asterisk vs rtpengine: at a glance
What is Asterisk?
The three-branch cycle closes: 20, 22 and 23 all promote to final with the same 28-issue set.
The release round that opened on August 7 has finished. Asterisk 20.21.0, 22.11.0 and 23.5.0 all tagged within a minute of each other, each carrying 39 commits from 16 authors, 28 resolved issues and zero security advisories. The counts are identical across all three branches, which is the same backport-in-lockstep pattern the certified track and the June security round both followed.
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.

Asterisk
5.0MEETINGS
The three-branch cycle closes: 20, 22 and 23 all promote to final with the same 28-issue set.
◆ Current state
The release round that opened on August 7 has finished. Asterisk 20.21.0, 22.11.0 and 23.5.0 all tagged within a minute of each other, each carrying 39 commits from 16 authors, 28 resolved issues and zero security advisories. The counts are identical across all three branches, which is the same backport-in-lockstep pattern the certified track and the June security round both followed.
◆ Where it's heading
Nothing about the shape has changed: three mainline branches plus a certified track, one fix set, promoted together. The rc1-to-rc2-to-final progression narrowed from 27 issues to a single websocket segfault fix and then closed, which is a cycle converging on schedule. Release bodies still publish counts and links rather than user-facing notes, so the feed measures release discipline rather than product direction.
◆ Prediction
Expect the certified track to pick up this same fix set in its next cert release, following the lag it showed after the June round. The next mainline round should open with rc1 tags on all three branches again.
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.
