How do we block spam calls?

Ok, we've run the *77 and got the message that the anonymous call rejection is now active, so we'll see how that side goes. As far as numbers, the hackers are rotating their Caller ID numbers so we don't have any that are consistently calling. If we find some that are recurring numbers, do we specifically need to submit those to Support or is there a function in our account on the site where we can enter those blocks ourselves?

Unfortunately, the numbers are nearly constantly changing - the only time the same number is used is if a repeat callback to us is made within a minute, and we've already gotten more than 12 distinct numbers of these calls this morning. Here is the list with time stamps from our last 60 that show in the call logs, if this helps with any tracking from your side:

@ssearles Thank you for reaching back out. We do ask that you not post phone numbers publicly. I see that we had provided a link to the instructions on how to set up rules to block certain calls. Were you able to set those rules up?
