Pager field being populated in AD but not showing in 365 tools

[DCurzio]

We have the contact phone number of PAGER in AD that we use for internal extensions.  We are a hybrid environment and we do sync that field up to 365.  The problem is that websites like SharePoint, Delve, and even the Bing work search won't show that field in the contact information.  How can we get this to show up as a standard contact field that always shows up?

Thanks for replying.  I added the pager field in the user properties, but unfortunately still not showing in Delve.  It isn't in the phone number format, but that is because it is a 5 digit extension.
