I think eventually this is going to result in some sort of "know your 
customer" legislation like the banking industry now has.  If all 
carriers would make logical decisions based on the customer, this would 
not be an issue.  We allow our larger and known customers to set CID, 
but if we take a telemarketing/call center customer we force their CID 
and ANI on our side.  Sure, some rogue admin inside any company could 
play games, but it's a lot less likely.

Have you checked to see if ANI is available and the same as the 
presented CID?
