Anywhere there is a phone number in BC should be a hyperlink to dial that number. In the old system, there was a button next to the Customer phone number. Now there is nothing. Click to call is increasingly common, so I'm not sure why a feature like this would be depreciated.

Anytime there is a URL, Email or Phone Number field in business central, it should be a hyperlink...save the button!

If for some reason a tenant didn't want this, you could make this an option in a setup window somewhere to enable / disable "Show Communication Fields as Hyperlinks."

In case this isn't clear, we're talking about URLs, TEL: and EMAIL: protocols.
