I oppose the use of non-ringing calls from unsolicited callers. I consider my cell phone a personal communications service, and I am against allowing any individual or porpoartion to access any function of that service or device that I employ on it. It is difficult enough to screen unwanted calls which are displayed, and allowing non-ring access to my voicemail or other part of my service is unacceptable, and provides me with no useful service. I accpet emergency contacts or other public service calls when I am able to distinguish who the originator is. I have enopugh frustration with the rise of call masking, blocking or number aliasing. I am not remotely interested in furthering the financial interests of a technolgoy firm simply because it beleives the technology to be useful. Carl DeFranco Ava, NY
