Digital Voice is what consumers have as an option while bundling their provider's offerings primarily for a home landline. While bundled with cell and cable..... I have found that the age of digital landline, digital voice is just another entry level for intruders to worm their way into your network. I have Guarded ID at home and Mobile Trust on my cell but these points of entry(Digital Voice) are a concern for all as the ability of an unscrupulous individual becomes more complex. I know this article leans toward cell usage but digital landlines may provide an area needing attention as well. At&T needs to get their act together as well as the other providers or the liability they are creating is going to have them in court.....often. JMHO
