3CX vs Eventzilla
A side-by-side editorial comparison of 3CX and Eventzilla — release velocity, themes, recent moves, and the top alternatives to consider.
3CX vs Eventzilla: at a glance
What is 3CX?
3CX is folding AI transcription and assistants into the PBX, and teaching customers to prompt them.
3CX has shipped V20 Update 9 as final, pairing a redesigned web client with AI features — Grok-based transcription, AI assistants, and improved queue management. The company is simultaneously running a customer-education push (a two-part prompt-engineering series) to get admins configuring those AI agents, and refreshing its mobile and softphone clients through a V5.6 beta wave. A parallel security thread is active, with recent CVE mitigations for self-hosted deployments.
What is Eventzilla?
One real theme release amid stale event-planning content
Eventzilla's feed pairs a single product update — five new event-landing-page themes — with a backlog of evergreen event-planning strategy posts. The entries run from mid-2024 to March 2025, so the crawled feed is stale by more than a year.

◆ Current state
3CX has shipped V20 Update 9 as final, pairing a redesigned web client with AI features — Grok-based transcription, AI assistants, and improved queue management. The company is simultaneously running a customer-education push (a two-part prompt-engineering series) to get admins configuring those AI agents, and refreshing its mobile and softphone clients through a V5.6 beta wave. A parallel security thread is active, with recent CVE mitigations for self-hosted deployments.
◆ Where it's heading
The phone system is being repositioned as an AI-assisted communications platform: transcription and assistants move from add-ons toward default expectations, and the prompt-engineering content signals 3CX wants configuration of AI agents to become a normal admin task. Expect the AI surface to deepen while the client apps converge on the redesigned UI. Security hardening is running as a constant background obligation given the self-hosted footprint.
◆ Prediction
The next updates likely promote the V5.6 client betas to stable and extend the AI feature set — more transcription languages or assistant actions — building on the Update 9 foundation.

One real theme release amid stale event-planning content
◆ Current state
Eventzilla's feed pairs a single product update — five new event-landing-page themes — with a backlog of evergreen event-planning strategy posts. The entries run from mid-2024 to March 2025, so the crawled feed is stale by more than a year.
◆ Where it's heading
The lone product move is cosmetic (landing-page themes), and everything newer is absent, so the trajectory is not observable — the blog appears to have stopped updating or the crawler is on an archived feed.
◆ Prediction
Without recent entries, no confident prediction; the feed source likely needs re-pointing to confirm whether product work continues.
