Angel "Moreno" probably a dude fwiw.
Angel, Sacha, Tima, and Skyler can be male names too. In fact, I think Sacha with a 'c' usually is male, and Sasha being the female spelling of it.
True also she could be one of the several paypigs who only had initials or fake names on their profile. I think the best course would be to clip her voice out and compare it to the prank calls. Because there really isn't another way. Below is a sample of her voice. I haven't heard a match between the prank calls posted in secureserver.tv and her voice yet, but I am one person I am sure I missed something.
