$locations array contains your locations (page titles), telephones and emails. You can expand it as far as you need.

Below are two fucntions defining shortcodes on your pages: [telephone] and [email]. They are similar. Each fucntion get the title of current page (get_the_title) and looks for it in $locations array, then returns corresponding telephone or email.

Your page can be like that:

telephone = [telephone]

email = [email]

Code is tested, you can see result here.
