3CX vs Red5
A side-by-side editorial comparison of 3CX and Red5 — release velocity, themes, recent moves, and the top alternatives to consider.
3CX vs Red5: at a glance
What is 3CX?
3CX put MCP and a dedicated AI server into the PBX itself, in an alpha.
Two weeks of releases, and the AI agent stack is where the work is. V20 Update 10 entered alpha with native Model Context Protocol support for connecting external AI assistants plus a dedicated AI Server for self-hosted inference and more granular admin control. Update 9 added emailed call details, summaries and transcripts from AI agents. Markdown knowledge sources were added to improve AI agent answers. Alongside that, the Windows Softphone hit V5.7 with one-click extension and account migration to the desktop app, and Yealink and Fanvil phones got firmware updates.
What is Red5?
Red5 ships constantly and explains almost none of it.
Red5 is a Java media server built around RTMP ingest and delivery. Releases come every few days — nine tags between early May and early July — but most publish nothing beyond an auto-generated link to the commit range. Two version schemes run side by side, with v2.0.16.46 appearing in July while the v2.0.3x series was still incrementing through June, so the tag number alone does not tell you which line a build belongs to.

◆ Current state
Two weeks of releases, and the AI agent stack is where the work is. V20 Update 10 entered alpha with native Model Context Protocol support for connecting external AI assistants plus a dedicated AI Server for self-hosted inference and more granular admin control. Update 9 added emailed call details, summaries and transcripts from AI agents. Markdown knowledge sources were added to improve AI agent answers. Alongside that, the Windows Softphone hit V5.7 with one-click extension and account migration to the desktop app, and Yealink and Fanvil phones got firmware updates.
◆ Where it's heading
3CX is turning the phone system into an AI agent host rather than a system that calls out to one. Native MCP means external assistants reach the PBX's data directly; a dedicated AI server means customers who cannot send call content to a hosted model can still run agents. Taken with Markdown knowledge sources and emailed transcripts, the shape is a self-hostable voice agent with its own grounding and its own output channel — consistent with 3CX's on-premises and privacy-sensitive base.
◆ Prediction
Expect Update 10 to move from alpha toward general availability with the AI Server and MCP surface intact, and further knowledge-source formats to follow Markdown.
Red5
2.5MEETINGS
Red5 ships constantly and explains almost none of it.
◆ Current state
Red5 is a Java media server built around RTMP ingest and delivery. Releases come every few days — nine tags between early May and early July — but most publish nothing beyond an auto-generated link to the commit range. Two version schemes run side by side, with v2.0.16.46 appearing in July while the v2.0.3x series was still incrementing through June, so the tag number alone does not tell you which line a build belongs to.
◆ Where it's heading
Where changelogs do exist, the work is concentrated in the RTMP hot path: cutting CPU waste and allocation churn on ingest, then addressing thread oversubscription three releases later. The one capability addition visible in this window is AV1 support. Everything else that is described is dependency maintenance — Spring, Bouncy Castle — and build plumbing like on-demand Docker image pushes. The pattern is a small maintainer group optimising a mature server rather than repositioning it.
◆ Prediction
Expect the RTMP performance thread to continue and AV1 handling to be refined in follow-up releases. The undocumented releases make anything beyond that guesswork — the changelogs would need to carry content before a direction could be read from them.
