The Panasonic digital hybrid systems support a local cell system that work with their wireless telephones. You install the cell packs throughout the property, and the phones roam transparently between them. They are available in DECT to avoid WiFi collisions, and the coverage is pretty good. I have deployed them in a 32K sq. ft. estate with no dead spots; we even put one out at the gate (300' from the house) so the housekeeper doesn't lose coverage when she checks for packages left at the gate. I imagine a plaster/lathe construction would inhibit reception somewhat, but you can set up a site survey in advance to see if it's feasible.
