At DSP we are “Operators” at heart, surely we can provide back as many phones as you would like, leading to wasted employee time and expense. Here, we take on all of the heavy lifting by processing through our robust phone database, and scoring each phone with a proprietary algorithm which then produces the DSP Best Phone for your consumer. Our process also allows us to de-duplicate up to (20) twenty previously held bad phones as to not deliver a known bad number.
