    I am having an issue with my blacklist for bogus caller is not working correclty. I performed a SIP trace from 3CX and this is what I see. It seems like it bypasses the blacklist check altogether?

    I did insert my number and it blocks it fine. But with Anonymous, 888-xxx-xxxx (or any toll numbers) it always seems to let them through. I have attached a trace form an 888 number that should have been blocked the number is 8888606650.

    Any ideas would be grealty appreciated. I have part of the list of my blacklist below to show how I am trying to block 888 numbers from coming in.

    What about a CID filter for 888 numbers to just drop the call?

    Hello @mark koskey

    If i understood well what you are trying to do, is to blacklist any incoming calls starting with 888 using wildcards. Using the * wildcard after a prefix like in your case 888 can be done by entering the prefix and then a single * only, like this: 888* . This tells the PBX to drop any incoming calls that start with 888 no matter what are the rest of the digits. The * start wildcard is used ones and it means that it will catch any digits from that point and beyond.
    I will be waiting for your feedback.

    Thank you
