Anyway to make separate headers for different pages? Libero theme

Question in title. I know that this involves making a new header file and that I must associate the header file with that individual page. But I don’t know what I must change in the header file to get this working. Also some of the elements in my header are controlled by widgets associated with the header position in WordPress.

How do I workaround this? All I’m doing is trying to change the site’s main phone number to appear as a different phone number on certain pages.
