[cisco-voip] Robo Call DoS

[Matthew Loraditch]

So this is a curiosity question, we had a prospective client call us who is essentially getting robocalled to oblivion. Some scammer has robo dialers setup and is flooding all of their trunks. He got a ransom, stopped and then started again. He was originally using one number and then when the telco blocked that switching to random sources.
Are there are any legitimate defenses to this sort of thing?
