Spam calling from numbers, most of which are forged is becoming a real issue and so we propose that we start to maintain a shared list of spam callers which can easily be uploaded from and downloaded to our (and any asterisk based) IP Telephone systems. 

Here's an example of currently blacklisted numbers:
