This MF is just fooling around and I guess he is try to get me in some kind of scam, they have called like 8 times.my kid answered and he or she didn´t say anything. Last time he calle I said hello and he did not answered and I ask to stop calling to my number.
I never answered the phone since I did not recognize the number (214-748-3647) but I did use a land line and blocked my number using *67 and I dialed this phone number and no one answered "hello" but there was an automated "goodbye" on the line and then it clicked off. I looked it up online and this number belongs to several companies in several cities in different states.
But, here's something of geekish signficance: 2147483647 happens to be the largest positive integer that can be respresented by today's 32-bit computer operating systems. I almost want to speculate that something in your caller ID software is producing this value. Either that, or the spammers who are making these calls are just using that as a fake value.
214-748-3647 is a very common bogus number used by spammers. It's a fake caller ID number generated by their spamming software (yes, it's easy to fake a caller ID). It's a 32-bit number with all bits (except the last) set to 1. For those of you who understand hexadecimal notation, that's the value 0x7FFFFFFF.
In case you're wondering, 214 is the Dallas, TX, area code. But there is no "748" exchange in Dallas. This number is fake.
