adding Clickable LINKS in Custompress fields

Field block used to allow users to easily add
PHONE NUMBERS..(ie each post has more than one phone number)

These need to be functioning links -
users are not web savvy and simply need to enter web and phone number
which will then display as clickable links..
ie web to site and phone to standard tap to call..

How to add this functionality using Custompress fields?
or is there a better option?
