Frequently Asked Questions
Are you really the best AI phone assistant?
Will the data be stored in the EU?
Our servers are located in , Germany Our company headquarters are located in Austria.
Where and how is fonio being developed?
We are one of the few providers of AI telephone assistants in Europe that are developing our own orchestration layer. This allows us to ensure that all data remains with us. This makes fonio special, as most other providers usually whitelabel US services.
Can the phone assistant only accept incoming calls or can it also make outgoing calls?
For outgoing calls, API key can be created on fonio. As soon as a phone number is transmitted to this API, our system initiates a call in real time. In addition to the phone number, variables such as... can also be used. The name will be given out in order to personalize the conversation.
How quickly can I have the telephone assistant ready to use?
The implementation time depends on the integration effort required into your existing systems. The AI can be set from within a few minutes and is then ready for use.
What if the AI makes mistakes?
Our AI makes decisions based on existing data, which virtually eliminates errors. Should the AI still be unable to proceed in a given situation, it can arrange a callback or forward the call to a human employee if desired.
