FAQ
Why does the app connect to the EDNT servers?
The app downloads the images and data of the supported providers from the EDNT servers at https://nrm.ednt.de. This content is not permanently integrated into the app so that our partners have the opportunity to make changes to the data.
macOS only: Why can problems occur under macOS if other telephony programs are installed?
If several telephony programs are installed under macOS, it can happen that they access the same audio input and output devices at the same time. Under certain circumstances, this can lead to unexpected behavior during audio transmission.
To ensure optimum use, it is advisable not to leave the input and output devices at the default values, but to select them specifically for the respective application.
