Asterisk vs BigBlueButton
A side-by-side editorial comparison of Asterisk and BigBlueButton — release velocity, themes, recent moves, and the top alternatives to consider.
Asterisk vs BigBlueButton: at a glance
What is Asterisk?
Four parallel branches, one fix set — Asterisk's changelog is a backport ledger, not a feature list.
Asterisk maintains mainline 20, 22 and 23 branches alongside a certified track, and lands each fix set across all of them at once. The June 25 batch was a coordinated security release resolving roughly 20 advisories on every branch simultaneously. The August 7 batch opens the next cycle with release candidates carrying identical commit, author and issue counts across 23.5.0, 22.11.0 and 20.21.0.
What is BigBlueButton?
BigBlueButton's 4.0 beta swaps out its own media stack — LiveKit is now the default, SIP.js is gone.
Two lines run in parallel. The stable 3.0 branch gets maintenance iterations every few weeks — security fixes, breakout-room and screenshare repairs, audio fixes against LiveKit — while 4.0 betas carry the structural work. The latest beta makes LiveKit the default media stack and deletes the legacy SIP.js audio bridge, replaces the shared notes engine with BlockNote, and moves the JVM services to Java 21. The layout system was rebuilt one beta earlier, with the Unified layout promoted to default.

Asterisk
5.0MEETINGS
Four parallel branches, one fix set — Asterisk's changelog is a backport ledger, not a feature list.
◆ Current state
Asterisk maintains mainline 20, 22 and 23 branches alongside a certified track, and lands each fix set across all of them at once. The June 25 batch was a coordinated security release resolving roughly 20 advisories on every branch simultaneously. The August 7 batch opens the next cycle with release candidates carrying identical commit, author and issue counts across 23.5.0, 22.11.0 and 20.21.0.
◆ Where it's heading
The visible output is backport discipline rather than feature development. Release notes carry counts, tags and advisory IDs but no feature text, so the changelog reads as a stability and security ledger for a mature telephony core. The certified track deliberately lags mainline and picks up a smaller subset of each cycle.
◆ Prediction
The three release candidates should promote to final within the project's usual short RC window, with the certified branch taking the same fixes a cycle later. Nothing in these entries points to feature work in flight.
BigBlueButton
3.8MEETINGS
BigBlueButton's 4.0 beta swaps out its own media stack — LiveKit is now the default, SIP.js is gone.
◆ Current state
Two lines run in parallel. The stable 3.0 branch gets maintenance iterations every few weeks — security fixes, breakout-room and screenshare repairs, audio fixes against LiveKit — while 4.0 betas carry the structural work. The latest beta makes LiveKit the default media stack and deletes the legacy SIP.js audio bridge, replaces the shared notes engine with BlockNote, and moves the JVM services to Java 21. The layout system was rebuilt one beta earlier, with the Unified layout promoted to default.
◆ Where it's heading
This is a multi-year replacement of the plumbing under a conferencing platform, done in public and in order: introduce LiveKit alongside the old bridge, fix audio against it across 3.0 point releases, then cut the old path out in a 4.0 beta. The same pattern shows in the client — the Unified layout arrived opt-in in 3.0.19 and became the default in beta.3. Around the core swap, the surface is being tidied: app gallery search and pinning, notification redesign, a request-to-present flow, configurable plugin buttons.
◆ Prediction
With the legacy audio bridge removed and Java 21 in place, expect the remaining 4.0 betas to be stabilization rather than new subsystems, and expect self-hosters to hit LiveKit deployment issues that generate a run of point releases after 4.0 lands.
