Series of calls incoming from what sounds like an International Fax machine, beeping away .. but first call is usually from a '02' nbr. You hang up, and then it repeats a couple of moments later, usually from a number in another state? (07 for example) and you will get up to a dozen of these, all different numbers, then cycles back to an '02' .. VERY DISRUPTIVE - especially if you have multiple lines, it will sometimes fill up ALL YOUR AVAILABLE LINES!! .. we had this issue back in 2024, and managed to get to the bottom of the telemarketing thing who had our number on a list. (I actually have the name/number saved somewhere, and we had to phone, lodge a complaint & request they remove our number - it seemed to work, but then we had a couple of episodes of this same thing again last year, and start of this year - today we've had 5 incoming of these bastard calls back to back, at one point tying up 3 of our company lines. We ought to be able to SUE for interuption of business operations!
