AI phone assistants are becoming increasingly popular – but many companies wonder: Is this even GDPR compliant? Can an AI conduct and record phone calls? The good news: Yes, it's possible – if you follow some important rules.

Note

This article does not replace legal advice. For specific questions, please consult your data protection officer or a specialized lawyer.

01

Why is GDPR so important for AI phone assistants?

Phone calls contain personal data: names, phone numbers, sometimes sensitive information like health data (for medical practices) or financial details. GDPR regulates how this data may be processed.

01Fines up to 20 million euros or 4% of annual global turnover
02Reputational damage from data breaches
03Loss of trust from customers and business partners
04Warnings from competitors or consumer protection associations

The 5 Pillars of GDPR Compliance in AI Telephony

1. Server Location: EU vs. USA

The most important point: Where is the data processed? After the Schrems II ruling, transferring personal data to the USA is problematic. Many AI providers use US servers (OpenAI, Google, Amazon).

Recommendation

Choose a provider with servers in Germany or the EU. bhomy hosts all data in Frankfurt am Main – 100% GDPR compliant.

2. Data Processing Agreement (DPA)

A DPA is mandatory under Art. 28 GDPR when an external service provider processes personal data on your behalf. The provider must offer and sign a DPA.

01Subject and duration of processing
02Type and purpose of processing
03Type of personal data
04Categories of data subjects
05Obligations and rights of the controller
06Technical and organizational measures (TOMs)

3. Transparency & Information

Callers must know that they are speaking with an AI. This follows from the GDPR's transparency requirement and the upcoming AI Act. A clear announcement at the beginning of the conversation is recommended.

Example Announcement

"Hello, you are speaking with the virtual assistant of [Company Name]. This conversation is processed for quality assurance. How can I help you?"

4. Legal Basis for Processing

For processing personal data, you need a legal basis under Art. 6 GDPR. For business calls, "legitimate interest" (Art. 6(1)(f)) or contract fulfillment (Art. 6(1)(b)) usually applies.

01Contract fulfillment: Customer calls to book appointment or place order
02Legitimate interest: Company has legitimate interest in efficient customer service
03Consent: For marketing calls or recording for training purposes

5. Data Storage & Deletion Concept

Data may only be stored as long as necessary for the purpose. Define clear deletion deadlines and document them.

01Call transcripts: max. 3-6 months, then automatic deletion
02Contact data: Depending on the business relationship
03Statistics: Anonymized data can be stored longer
