Query: Unreliable...

When this phone works, it's fabulous. It allows me to store dozens of phone numbers, any of which it can call with a simple press of the jog dial. It looks good, and provides caller identification. Unfortunately, this phone doesn't work about 30% of the time. All too often, when I pick up the handset to make a call, the screen reads ' CONNECTING' and the phone is dead. Also, sometimes the names and telephone numbers will become go from being represented on the screen by letters and digits to unreadable symbols. All very strange. Thank goodness I have 2 other telphones in my apartment.
