Hi, Keith:

The root cause of phone spam is because Caller-ID service was first deteriorated by a marketing gimmick that enabled the spoofing of the Caller-ID. Combined with eMail spam techniques, VoIP operations have now become out of hand. Below is an overview of these annoyances. This is a topic that I am not sure whether NANOG is the proper forum to deal with. Although, certain parameters and considerations are closely related to the Internet issues.

With AT&T and perhaps others, you can forward the message to 7726

This is, of course, the root of the problem.  The recipient of the spam does not know either the originating phone 
number or the originating e-mail address.  All they know is the Advertizing ID -- and that is useless for everything 
except what it was designed for -- advertizing.

If one knew the originating phone number then one would know who to hunt down and which throat to slit from ear to ear, and 
there would be no need to involve AT&T at all... This, and the fact that the Telco's get bloody rich from providing 
termination for all the crap they have enabled is exactly the reason they did it in the first place!
