@thecreativeone91 im using 2n gateway and voipswitch.com. we found a solution by filtering these number in voipswitch so they dont pass. the thing i want to know why most of the voip companies do this sending fake calls
How would they determine a real or a fake call? They are all the same.
Think of it like you have a phone at home. Sometimes you make calls to your cousin to see about going out for dinner tomorrow. Then your kid makes a prank call to a restaurant and asks for a patron with a silly name. There is no way, looking at the voice traffic, to know which calls are real and which are prank. When you hear the call it is pretty easy to determine, but humans can determine these things in ways that computers cannot. And even humans often fail - or else prank calls wouldn't be funny. And even if they could make the judgement call, the voice trunk provider doesn't have the right to block calls, nor the responsibility, nor any incentive.
