Level3 will notify us... about 24-48 hours after we've already discovered it ourselves and taken appropriate action. ANPI is about at 4 hours or so. Again, usually after we've already detected it. So while it's nice that upstream carriers notify, it's usually well after a significant bill has been racked up. It's best to be proactive on your own as much as possible. I'm actively looking for more and better ways to be proactive ourselves also. There are still some that get through the cracks now and then. --- Brandon P.

The attack seems to be for financial gain in that the most frequent destination is a conference call service in Poland, that possibly keeps calls open waiting for a PIN to be entered. Is there any basis for expecting that the upstream carrier should have some protections that would limit our liability? Thanks, -mark P.S. For those people who feel compelled to point out that we should have (better) protection on our end: Yes, Thank you, message received! _______________________________________________ VoiceOps mailing list VoiceOps at voiceops.org https://puck.nether.net/mailman/listinfo/voiceops _______________________________________________ VoiceOps mailing list VoiceOps at voiceops.org https://puck.nether.net/mailman/listinfo/voiceops
