I can activate email addresses to send an email. But if someone is on their phone and they want to call by touching the phone number on the screen - is there a way to do that or is it something the phone will recognize?
A normal telephone number as an HTML item is recognized by mobile phones as a phone number, so taping it will dial the number.
To link a phone number to a graphic item, select the item, right click, then select hyperlink and select external at the top of the window. From the protocol drop down select “tel:” (at the bottom) and type the phone number you require in the box below.
