FreeSWITCH: sovereignty score and 8 European alternatives

FreeSWITCH is an open-source framework for real-time voice and video. It is intended for building voice and video services on servers operated by the user. The software is published under the Mozilla Public Licence (MPL), and the vendor offers an open-source edition that organisations run themselves. Downloads require a SignalWire account.

SignalWire develops and maintains FreeSWITCH, employs the original FreeSWITCH authors and is headquartered in Palo Alto, California. As a US company it can be subject to US legal access rules, including the CLOUD Act, for data it holds. The software itself can run on servers in the EU, so a European organisation that operates its own installation keeps control over call and media data. Organisations that use a SignalWire cloud service should check its data-processing terms and where that service stores data.

Why digital sovereignty matters with FreeSWITCH

FreeSWITCH is headquartered in the United States. US vendors fall under the CLOUD Act and FISA 702: US authorities can compel access to data, even when that data sits in a European data centre. That is the core of the jurisdictional exposure in our model.

FreeSWITCH hosts data outside the EU (US). Personal data therefore leaves the EU, which requires a transfer mechanism under the GDPR and pulls the data residency score down.

FreeSWITCH is open source. You can audit the source code, self-host the software and keep the encryption keys under your own control. Switching is easier because data and software are not tied to a single party.

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