Damn...that was easy. Scary easy.

Everything worked on a SIPGate trunk until I tried advanced-flood.py. SIPGate only allows you to set incoming caller ID through their API (though you can set the outgoing ID on their web interface). They're a great ITSP in all other respects, but I did end up setting up a free Flowroute account to run the attack successfully. (It took me 5 minutes from signing up to running the script. Like I said, scary easy).
