One time when I was using the phone the display of who was calling went away. I also don't have 3-way calling anymore - all out of the blue. I still see the date and time when I lift the handset but otherwise it's blank. I use this phone for my home business and I need all these features back. Did I do something? Did something break? Please get back to me ASAP!!! Barb Perrella 218-728-5905 Barb@BarbsHomeBiz.com
