Marketing company from Hialeah. There is trend to use software that temporary uses a designated number to make a call, then the number changes to another one, in order to avoid being block by users..This company uses this type of software, very difficult to track, but like the golden rule says "Don't pick it up, if it is not on your contact list"...unless you are in sales o marketing your self, there are not many strange numbers that call you... common people like most of us, are better without answering the calls of weird or unknown numbers.

7864500077...automatic morphing call maker that checks for the existance of numbers assigned to people. if you answer, the telemarketer will know the number is real and that it is assigned to someone, then they place you a a list of viable number to be called.
