Re: A few at fault here
2) I've seen plenty of small businesses supplied with the terrible Home Hub 3 (even worse, the type A).
TBH, the VOIP fraud attempt volume is quite staggering. I've recently been playing about with Asterisk, and wanted to test by connecting to it externally, it was flooded with attempted call attempts (lucky that I'm not so new in telephony that I had unrestricted outbound permitted!).
It truly was a staggering volume... It didn't gradually ramp it, it was just there! attempts to dial 9nnnnnnn, 00nnnnnn etc etc... As I said, I didn't have any outbound routing configured, so they didn't go anywhere... But I did decide to have some fun with them by sending back 60 seconds of recorded ring tone... (I know, probably did nothing, but if it held up one if their spider threads for 30 seconds, it's a start!).
