I have been haveing a problem with my office system since I moved in here. I have changed out all the cabling and cabinet and cards. When I am on the phone my display of the phone I am talking on starts showing all kind of zero's and collons and starts marking time. I have spent an hour on the phone with tech support and they said it is environmental issues I have changed extions and reprogrammed so many times I lost count. I am out of ideas as for what to look for next. If anyone has ever seen this before I would appreciate any ideas! I would hate to think that I am loosing my mind at such an early age!!!!!!!!!!!!!!!!!!!
