callers with withheld caller id unable to connect

[oakley]

If a caller with a withheld caller id call the 3cx system they get what appears to be a recording saying the number is unavailable. Is this something in the 3cx setup or could it be my SIP provider doing this?

Check the 3CX Activity Log right after one of these call. Does the call show in the log? If not, then it is blocked outside, somewhere. It is odd that the caller receives a recording saying the number is unavailable. In most cases, a recording asking the person to unblock their number, and call back, is reached.

Hello @oakley

Unless you have a CID rule that blocks Anonymous callers then the 3CX PBX should not have an issue receiving anonymous calls. Check with your provider in case they are not allowing these calls.
