Olympia's DualPhone appears to be a single handset, does anyone make a similar device that supports multiple cordless handsets? As in, one base station with it's USB interface and multiple cordless handsets that speak through it?
Ideally it'd also support multiple lines but I could live with just one at the present.
Otherwise, whose adapters would be best suited for interfacing skype and voip into a multi-line cordless phone that supported more than one handset? Preferrably not on the 2.4gHz frequency range.
