Query: Panasonic 2 line 5.8 GHz phone

I purchased this phone and used it for 2 weeks, finally returning it as there were too many missing features.Pro: Good voice quality, ability to share one or all directory entries among headsets. Worked well with normal POTs line and VOIP line.Con: Callerid doesn't display number if name is unknown, and would often not display anything even when other phone showed name and number. Since I screen my calls, this was unacceptable. Call log only stores unanswered calls. Had trouble reading display when awakened by phone ringing (before my eyes had a chance to adjust).
