Anyone looking for "the best AI phone assistant" is looking the wrong way. Don't compare brands, compare criteria.

## 1. Data Protection & Hosting
Servers in the EU, a data processing agreement, a deletion concept. A foundation, not a detail.

## 2. German Language Quality
Natural voice, low latency, recognition of colloquial speech and dialects. Best tested yourself.

## 3. Use-Case Fit
Inbound, outbound, or both? Pure relief or genuine dialogue handling?

## 4. Integration
Connection to your phone system and workflows – and notes where the team can see them.

## 5. Billing
Transparent, billed by the second, without long-term commitment.

## 6. Industry
Healthcare, finance, and the public sector often require special documentation.

## How to Proceed
Define the use case, shortlist 2–4 providers, and test with real calls. webRichtung phone is the EU/GDPR-compliant option with billing by the second and a start within 24 hours.
