U.S. Robocall Data (robocallindex.com)

Thanks, I found it there! I never thought to look in the settings of the dialer app, but that makes a lot of sense now that I think about it.

I also ignore most of those calls now. It saves a lot of my time. I sometimes just Google those numbers and block them in the end without even talking to them. I have also read a nice article regarding this topic at https://www.lemberglaw.com/what-are-robocalls/.

Yeah, but that would require a person use a different phone number, right? Or are you saying the customer just forwards all of their calls to Twilio which... somehow forwards it back without the call getting forwarded?
