We have / have had phone in the master bedroom, two kids bedrooms, bonus room, family room, kitchen, computer desk, etc. Some being two line phones one being a 4-line phone. All working quite well using our old fashioned approach with VOIPo supplied ATAs. So, I'd need a 2 line DECT base station with multiple handsets (say half a dozen) using your approach. Right? Do you have such a setup? If so curious what kind of money we're talking about.
