@momurda said in Blocking phone numbers:
rally i have found the numbers are sold or used in blocks of a few contiguous numbers like 123-1230 123-1231 123-1232 etc if the operation is serious about their fraud.
The portal for our voip provider makes this incredibly easy to do.
I do block some numbers and anonymous calls, but as stated above if they want to keep coming, it will come with the same 201-xxx phone number and they just randomize it. (That's my case).
