All of a sudden incoming calls from cell phones with blocked caller ID are getting "this number isn't accepting calls" message.

I work for a Sheriff's office and all the deputies have their caller IDs blocked on their phones. Starting sometime between Friday and Monday morning this week all of their calls are being blocked. If they turn off the caller ID block the call can go through. I can't find any active rules to block unknown callers, does anyone have any ideas? We're running Version 20.0 Update 6 (Build 724 Release)

Hello randomusername09963,

When you look in to the admin > Reports > Call Logs
Do you 'see' the call come into the 3CX system? any record of the call there?

If NO, then the call is not passed by the provider, check with them.
If YES, then look further in the 3CX, check Admin > Advanced > CID Blacklist
