How can I encode a telephone number which, when chosen, starts a call?

How can I encode a telephone number such that when a person chooses it, it starts a phone call.  This would be analogous to a hypertext marker with the command "GO to URL" or "Message Client."

Thanks!

It would appear that one would use URI Scheme "tel":
message URL tel:+1-201-555-0123
per RFC3966

But as Jeff's StackOverflow thread reference indicates, whether or not it works may be client-dependent. If it doesn't, and you control the client (device, browser), then provisional URI Scheme callto: might be worth a test.

A further question arises as to whether the URI is delivered to the client via HTML/XML, or inside a PDF.

I've never needed to try any of it.

The reply from Bob Niland (Error 7103) is correct.

    NOTE

    FrameMaker changed the plus sign ( + ) to an exclamation point ( ! ).

In the hypertext marker, I used the command Go to URL with the content message URL tel:!1-260-745-2907.

On my Samsung Galaxy J7 with Android ver 8.1.0 with the tel nbr encoded in a PDF file, when I choose the "hot" nbr, it ran the default app for phone.  To call the nbr, I had to choose the green tel handset icon.  This intermediate step provides a convenient opportunity to either stop the process or to continue it.

Thanks!
