Unfortunately, it seems that many phone spammers and con artists don’t like to hold onto the same numbers too long, because people start to recognize and block those numbers. ![]() But a few months back, I simply started blocking all calls that come from their exchanges in my home state and surrounding states, plus a couple other states that tend to be big originators of spam calls, and that has dramatically cut the number of spam calls that make it through the system. I’m not going to name them because they might take offense to being called out as spam enablers, and they probably have lawyers. While it is understandable that big providers like Verizon or Comcast might continually need new number block assignments as they add customers, it’s a bit more puzzling why some companies you have probably never heard of would need so many new numbers, until you realize exactly how those numbers are often used.Īs least two of the less well known company names on those lists are companies that I recognize as being the originators of better than 90% of the spam calls that come into my PBX. If you go to and pick a recent month to display, it will show you all the new thousands blocks of telephone numbers assigned in that month. Now you may wonder how useful this would be, but consider this. Partial number matching would let you say that if a caller ID number begins with the specified digits it would be blocked.

The two main improvements I would suggest are blocking based on Caller ID name, and partial number matching. It could be a much better tool in the fight against spam callers if it were brought up to date. ![]() As far as I can tell the blacklist module has received virtually no love or attention practically since its inception. ![]()
