Contacts names not showing the names from contact manager on when calling, on my Sangoma P320

I’ve uploaded some contacts into contact manager, it work great, the phone makes the request and reads the contacts, all good here. However when i click on a contact to call it, on the dialing window i only see my number and the number i’m calling. Is there a way to make it use the contact name instead of the number? Someone already asked this a couple of years ago. Has anyone fixed this issue?
