I've heard more than once of people getting irate calls from strangers accusing them of calling them with scams. Unfortunately what has happened is the randomly generated number some scammer used happens to be the actual phone number of some poor sap who has no knowledge of their number being used for this.

I don't know, just passing along information. :-//

Another Robocaller False Alarm!

I watched the video. I see no valuable new information. The links in the OP give the story in a much cleaner fashion. As has already been noted, it is a dynamic situation.

The approach of screaming; it is just a FALSE ALARM, it won't work and, they could fix it if they wanted to ....is not valuable information to me - it is simple venting. Did I miss the grand proposal revealed in that video? You know, the one that would fix the problem?

Happens also over here. Despite local regulations enforce correct caller IDs for call centers, telcos don't check the IDs of calls originated in other countries. A while ago some Indian call enter tried to scam me and they have set their caller ID to a different German number each time they called. AFAIK, it would easy for telcos to overwrite the fake caller ID with the correct line number as they receive also the line number from the originating telco for billing reasons. For a legitimate custom caller ID, like a local toll-free number for a call center outside the country, they could implement some registration process to allow the custom ID.

If it's a real caller, just put the phone up to the smoke alarm and press the button. Or better yet, perhaps someone can figure out what bit sequence decodes to the loudest possible sound and write an app to blast the scammers?

When I took their first call I cursed them in Hindi. ;D   hint: search for "bad words in Hindi"

The idea with the loud sound might work also. But I would implement it in my VoIP PBX.
