A few weeks back, one of our client TFN #s got hit by 60,000 calls per hour. The number was not active so none of the calls were answered, but it was just odd... The two ANIs were not in service. We removed the CICs so as not to annoy the carrier and called it a day... only because it wasn't an active number. Not sure what we would've done if it was.

We had a client complain about something similar. They have nothing more than a trunk, so we looked up our CDRs and found nothing no inbound at all. We determined it was something hitting their PBX directly. I'd perform a packet capture when this occurs, baseline whatever is common in these packets, and look for a mechanism to block that. E.g.: if [ all packet contains this - only found in bad packets ] then do something fi -- =+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+ J.
