Inbound Caller ID - Skype for Business Cloud PBX

Running a VVX 600 phone ( on Skype for Business Cloud PBX.  I can't seem to get incoming caller ID working.  Incoming calls just show the number, but don't translate the name.  I confirm that I have them in my contacts, that the phone can search for them in the GAL.  In Skype for Business on the PC, I can right click on the person and choose "Call", then see all their numbers (Mobile, Work, etc). However, if they call I don't get Caller ID.


The only Caller ID I get is when someone makes a Skype call to the phone - but PSTN doesn't seem to work.


Has anyone else been able to get Caller ID working?

You need to add the contact locally on the phone in order to display the name instead of the number.
