Phone call links in Power BI
Due to recently changed restrictions for custom visuals, phone call hyperlinks currently don't work anymore the way they used to.
The good news is, that we have a workaround in development that looks very promising. We currently don't know if this workaround will ever be integrated into the visual or be a stand-alone solution. Technically, we have developed an Azure function which creates dynamic redirects for different protocols other than https.
If you are interested in using these kind of links (again), please reach out to our support.
