3CX: sovereignty score and 8 European alternatives

3CX is a software-based business phone system (PBX) built on the SIP standard. It connects calls to the public telephone network or to VoIP providers and includes call recording, IVR, voicemail-to-email and call-centre features, alongside video conferencing and live chat. Users work through a web client, desktop and mobile apps or SIP phones, and a Microsoft Teams integration is available through direct routing. You can run the system yourself on your own infrastructure, have it hosted by 3CX, or have it hosted by a 3CX partner.

3CX is headquartered in Nicosia, Cyprus, which is inside the EU, and is a privately held company. Where your data ends up depends on the model you choose: a self-managed installation stays under your own control, while with hosting by 3CX or a partner that party operates the system. Ask which data centres and regions are used for hosted setups, and record the answer in your data processing agreement.

Why digital sovereignty matters with 3CX

3CX is headquartered in CY and therefore falls under European law: the GDPR, NIS2 and the Data Act. No foreign legislation can compel access to your data.

3CX hosts data in EU, US. Exactly what stays within the EU — and what does not — is defined by the vendor's data processing agreement and sub-processor list, not by a setting you control yourself; check those documents for the precise scope, including backups, logs and support access.

3CX is closed source and hosted by the vendor. The encryption keys and the runtime sit with the vendor and switching requires data migration. Ask about bring-your-own-key, export options and open standards.

What this means for your organisation depends on your whole stack and context. The free assessment weighs 3CX together with your other vendors and gives a total score, a heatmap and the main risk drivers.
