The integration uses standard 3CX features available on the Standard and Professional editions of 3CX v18 and v20. Specifically, it reads the call-event webhook and the recording URL. No exotic edition is required, no custom build.
Connect Zero for 3CX works on these editions. Older editions (3CX v16 and earlier) are not supported because they lack the call-event webhook API we depend on.
Hosted on 3CX cloud or self-managed. Full feature support.
Full feature support including call queues, IVR routing context, and the Pro reporting hooks.
v20 is the current supported release. New deployments should start here.
Two 3CX features power the whole integration. The call-event webhook fires on every completed call. The recording URL points at the audio file. Connect Zero reads both via standard 3CX APIs; no custom plugin is installed inside 3CX.
Standard 3CX feature on all supported editions. Configurable in the 3CX admin console.
3CX call recordings stored per your retention policy. Connect Zero reads the URL and forwards to the CRM without re-hosting the audio.
Nothing installed inside the 3CX tenant. Everything runs from Connect Zero infrastructure via standard APIs.
If you are unsure about your edition, ask your 3CX partner or check the 3CX admin console version banner. Then install from the marketplace; the trial runs for 14 days.
