You are the one doing the PST, just e-mail them the excel file, have them save it on their desktop and provide instructions File Import/Export > Import > Excel and select Contacts.
There are no ways to do it without their interaction unless you have access to all their accounts.
Or you could make a website with the contact information and the user could highlight the phone number to call it.
