Stay tuned guys. I own a tech company and I have my guys writing some software for hammering these scammers back (Call Flooding).
The method I am using now, using RingCentral is good, but I spend many hours a day on this (5-10) because I have to monitor when they block me and then change my info in RC. So, it is VERY FUN, but not entirely user-friendly. I can usually do a good 30-minute stretch while taking care of other matters before I have to change phone number and caller ID name.
In all fairness much of the 5-10 hours per day is me watching the mouse move by itself and listening to scammers yell and curse at me (I am a simple man... previous to this I liked watching dust collect on the Window sill).
Anyways, when the program is completed I will let all of you have it. "Project Mayhem" (See YouTube) is also working on something similar for call flooding scammers, but he isn't moving that fast on his project..... but neither are we, for that matter, I guess.
We are trying to avoid call fees, which makes our custom project VERY complex. If you are willing to pay .004 (4 tenths of a penny) per call per minute then we will have also an option for using Twilio.
Much is going on here, and much to relay to you as time goes by.
Suffice it is to say I am a man with many resources at my disposal and I am out for VENGEANCE! And I WILL NOT STOP UNTIL I BRING DOWN ALL REPORTED SCAMMERS. (Granted they just change their number, but with most services that is a difficult task. Only RC has an instant method, as far as I know). Sorry for the long post. There is so much I have to say! haha
