rtpengine vs Whereby: at a glance
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.
What is Whereby?
Whereby ships monthly digests aimed squarely at the embedding developer, not the meeting host.
The feed is a run of monthly SDK and product round-ups, consistently framed around developer experience rather than end-user features. The specifics that do surface are embedding-side: session ratings for call quality feedback, session insights, stronger authentication options, and a native iOS SDK that left beta earlier in the year.

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.
Whereby
2.5MEETINGSCOLLAB
Whereby ships monthly digests aimed squarely at the embedding developer, not the meeting host.
◆ Current state
The feed is a run of monthly SDK and product round-ups, consistently framed around developer experience rather than end-user features. The specifics that do surface are embedding-side: session ratings for call quality feedback, session insights, stronger authentication options, and a native iOS SDK that left beta earlier in the year.
◆ Where it's heading
Whereby is a video product sold to developers who embed it, and the cadence reflects that: incremental SDK work, quality telemetry and authentication rather than the in-meeting AI features that dominate the conferencing category. The digest format itself is the notable pattern, since it bundles a month of changes behind a generic headline and makes individual releases hard to assess from the feed alone.
◆ Prediction
Expect continued monthly SDK round-ups with quality and telemetry themes; the entries carry too little detail to predict a specific capability with confidence.
