Summary: This phone system works just fine however, it doesn't last very long. In about two years, all the handsets are failing - but it's really the only one on the market that does what we need it to do. The internal system itself is straight forward enough and easy to use, but the quality of the product is extremely poor.
Summary: I bought this phone for the 2 line function. I have 2 lines and each has call waiting and 3 way calling through use of the flash key. It never occurred to me that the phone wouldn't support 3 way calling. I can call out on line 1. I can hit the flash key and call a 2nd number on that same line. However, there is no way to bring the lines together for a 3 way call. I contacted Panasonic.
