If you use Safari instead of Chrome, you can highlight a phone number (you can also triple-click to quickly highlight the entire phone number). Then, macOS will give you a pop-up menu to dial the number. Unfortunately, this doesn’t work in Chrome. Maybe there’s some Chrome extension to make that work.
I think the issue is that Airtable chose not to support the tel: protocol (i.e., tel://999-999-9999) natively in its URL field. There are many different URL protocols and tel: is the one that makes it possible for click-to-dial. This same behaviour should be possible on the mobile devices (not sure - never tested).
Unlike Chrome, Safari chose to support it as well as native entity extraction to make it possible to dial phone numbers even when the tel:// protocol was not applied.
But… there’s an out on Mac that requires no additional effort.
Simply enter your phone number data into a URL field like this:
… and it will work.
