I have a strange problem with phones behavour in a specific department called "Borgerservice" in my "Cisco Unified CM Administration System version 18.104.22.16800-2" installation.
If the users in this department call to another user in this department, they can both see the name and number of the person in the other end.
But if a user in this department calls me in the IT-department, I can only see her number on my display, not her name and number as I normally can then other users from other departments calls me.
I have checked her end-user profile and her telephone number, but both have the exact same settings and configuraiton as my phone and end-user profile, so I can not see where this behaviour comes from.
I have attached the end-user configuration and phone-number configuration on both me (not having this issue, no mather where I call) and one of the users having the problem (but only when she is calling outside her own department.
Can you see why this strange problem exists?
Maybe you should check the line configuration of the phone, there is Display (Internal Caller ID). I think that you should set the caller id in this field.
