SMelissa...no disrespect, but there's always going to be LE and crazy people out there...whether it's incall or outcall. To lower the risk...all you have to do is implement a stricter screening policy. And, invest in a background/reverse phone search...I do and it's been very effective.
How well does Intellius work with all the new VOIP calling ability? Besides the ones from the major telecoms, like Skype, Yahoo etc, does it register in Intellius?
They detect the number as being as such...and when I come across hobbyists who cover their "real" phone number...I simply ask why and for them to submit the correct number. If they don't have anything to hide...they will offer their "real" number.
