Google Voice: sovereignty score and 8 European alternatives

Google Voice is a cloud phone service from Google for individuals and organisations, part of Google Workspace. It offers a business phone number that works across devices, calling from and to Gmail, voicemail with transcription, ring groups and automatic call menus. SIP Link connects existing numbers from another carrier, and higher plans add call recording and eDiscovery. It is managed through the Voice admin console.

Google LLC is a subsidiary of Alphabet and is based in the United States. For Workspace services Google acts as a processor under its data processing addendum. Workspace's data-regions policy (US or Europe) lists a set of core services, and Google Voice is not among them, so a European storage guarantee is not documented for this service. Availability differs by country. For a European organisation this means telephony and call data sit with a US company and can fall under the CLOUD Act. It is not open source.

Why digital sovereignty matters with Google Voice

Google Voice 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.

Google Voice 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.

Google Voice 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 Google Voice together with your other vendors and gives a total score, a heatmap and the main risk drivers.
