3CX vs BigBlueButton: at a glance
What is 3CX?
3CX keeps its VoIP platform current while nudging an AI phone agent forward.
3CX's feed mixes maintenance and marketing — handset firmware, app version bumps, awards, and discount promos — with occasional product substance. The notable thread is the AI Agent: guidance on Markdown knowledge sources points to continued investment in an in-platform answer bot for calls.
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.
3CX vs BigBlueButton: editorial side-by-side
3CX
5.0MEETINGS
3CX keeps its VoIP platform current while nudging an AI phone agent forward.
◆ Current state
3CX's feed mixes maintenance and marketing — handset firmware, app version bumps, awards, and discount promos — with occasional product substance. The notable thread is the AI Agent: guidance on Markdown knowledge sources points to continued investment in an in-platform answer bot for calls.
◆ Where it's heading
The core telephony product sits in steady maintenance (SBC betas, Debian 13 support, softphone releases), while the differentiator being pushed is the AI Agent layered onto the phone system.
◆ Prediction
Expect more AI Agent tuning — knowledge formats and answer accuracy — plus routine platform and firmware upkeep; no directional break is visible in this window.
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.
