This is a VOIP voice over IP call.
Likely used to find people that answer the phone.
Always ignore all unknown calls, never answer them, never call them back.
I assign all calls not in my contact list a ring tone sound of silence.
They called twice within a few minutes of each other and didnt leave a message. I called back and got a busy signal. Again ???why are we on the do not call list???
I found this on CallerComplaints.com
Spoofed Numbers: Caution, 347-211-3774 is a "spoofed" number, which means that whoever called you "tricked" your caller ID to display an incorrect phone number. Telemarketers do this so you cannot complain, but they failed... you can still file a complaint here to fight back against unethical telemarketers.
I received 3 calls from 347-211-3774 & it came up NY & they left no msg I tried call to call & it was a quick busy signal so they called a 4th time I just put them on speaker phone & they immediatly hung up! Very creepy !
