content: We bought the Siemens 2402 with two receivers and then a another 2.4 GHz Siemens two-line with two receivers. Both systems exhibit the same really bad quality. Conversations are cut off, as though every other word is transmitted. It seems not to be a range problem, because the problem occurs whether we are five feet from the base, or 100 feet. I finally concluded it was just a lousy quality phone system, especially since the same problem occurs in both systems. Siemens has been totally unresponsive, sending me standard, unhelpful responses to my inquiries.
