It means that the caller has blocked, or "restricted" their number from your caller ID, so you will not know who is calling until you answer. You can:
Calls that are forwarded to my Galaxy S7 through our company phone system are all marked "restricted" regardless of who is calling. This did not happen on my old Galaxy S4, which simply passed along the regular Caller ID information (either the incoming phone number or the contact name from my phone. Our company phone system settings have not been changed. Is there a setting on my S7 that can fix this?
It was also reported Galaxy S7 and S10 are having the 'restricted' call issue through Cisco Call Manager where it did not happen on their Galaxy S4 and no settings were changed on Call Manager. I would suspect some setting on S7 or S10? This is definitely interesting.

We understand you're experiencing a strange problem where your saved contacts are showing up as a restricted caller. This is certainly odd. Do you know if they have settings which hide their Caller ID? Is this happening with all calls or just some?
