Could be. I’ve contacted a few spoof numbers letting them know they’ve been used. Always on a different phone that I don’t care who gets that particular number.
I send that, “I am in a meeting. Please Text Me.” message back to spam callers probably a few times a day.
Only once has someone replied saying who is this?
Full Disclosure, I work in the telephone industry. We know what the spammers are doing, and we want it to stop because it upsets paying customers.
Call Spammers simply use an algorithm that has each call send a unique random Caller ID number to people with the same first 6 digits. They are assuming that you will think it is a neighbor.
