I have seen this as well, though with more malicious results such as 911 hangups with the customers callerID.
I would love to hear any suggestions on tracing the malicious calls as well, since I know there are a lot of ITSP's that allow customers so send whatever callerID they want so this might be an exercise in futility.
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?
If this is coming in SS7 you should have the JIP in the IAM as well as a charge number. You can use that to track down the originating carrier and give them a yell. -Paul
