Hubby says this equipment (a PCI card that goes in a computer) can work
through the home phone line, thus showing a call was made from home. The cell company's records show call was made from home phone b/c it truly was - just programmed to do so through this computer/card. He would need to then discard this PCI card and whatever computer he used. I was just told that even the kids' (our old) computers we have around here would be able to do the job.
This is the info he just sent me -
