I too would also be curious to see what Cisco pointed you to if anything.

Having just sold a couple of AVVID's, I am interested, though in toll fraud and how it is pulled off. I know that in the PBX world there are or were certain timeout settings that generally had to be adjusted down to zero so that a hacker couldn't to an effective DoS and get dial tone. ( IIRC, hackers would use a "blue box" and just keep pounding a PBX until it gave up and offered dial tone. There were specific timeout settings that had to be zero to prevent this, IIRC ) Chris, without revealing the specifics of your situation, were there / are there specific Call Manager configurations you were able to change to prevent this going forward? Did Cisco point you to any specific links to read up on?
