I suppose you might say that this one is legit. IDNA, no msg. I used my spoof number to c/b. A pleasant man with an Indian, or there about, accent answered. He didn't talk so fast that you couldn't understand him. A nice change, I'm from Texas, I listen slow. They are cold calling about mortgage refinancing. I declined and he didn't come unglued. So your mileage may vary. Good luck on this mission.
"I suppose you might say that this one is legit." They are calling from an unidentified number but you claim they are "legit" even though you don't know the real company name? "A pleasant man with an Indian," So it could have been anyone you talked to, but they are "legit" because he was "pleasant"? "They are cold calling about mortgage refinancing." So they are violating the DNC by cold calling? Doesn't sound too "legit" to me.
Now the even bigger question is why you are here. People look up things because they want to know more, but yet we have you who seems to know everything there is about this number. So why did you look it up?
