Making phone # "clickable" go straight to phone app on mobile

Greetings!

I was wondering if there is a way to make a phone number in mobile versions a website clickable (tapable) so that once tapped, the number is called right away.

I see this pretty commonly so I was wondering if this is something pretty easy to implement or if Upfront has that capability.

Thanks!
