I switched to Comcast telephone service a few years ago and my rotary phones worked just fine with their modem--until they didn't one day last May. Some damn software upgrade came through and that was it, no more rotary. I finally got a refurbished Panasonic PBX to restore the old phones' functionality. It has the added benefits of A) making all the phones double as intercoms and B) greatly increasing the potential number of phones that can be in service at once. As if I need to expand another collection....
