Thanks for the information. Over the years I have tried tons of "software" based free internet phone call services, like dialpad. I even paid fees to phones like net2phone, with required you to use headphones on your computer.
Because the Cisco ATA 186 is a stand alone unit, using your internet connection rather than PC, in the future it may be an easy target for hackers that want to tap your phone calls.
Right now, just having a phone service in another city/state/country, which allows something to make and receive calls is a big bost for the adult industry.
I will keep my eyes open for additional information regarding VoIP call privacy.
Thanks
