When I was thinking about trying one of these boxes I stumbled upon something somewhere that mentioned some recommended spec of the phones that will work properly with one of these wireless boxes. Could have to do with that voltage trigger I mentioned in my other post. When the phone rings, the signal is a 20 hertz AC signal (about 90 volts). When in use it is a modulated DC signal (between 6 and 12 volts). How these boxes handles that could be some of these issues. ??
