Unique from Orange to rival Fusion from BT

It's not quite Unique as Orange are copying BT, but their service will work on WiFi not Bluetooth (like BT's corporate Fusion service).

Orange's service will use dual-mode WiFi/GSM handsets and work over an Orange broadband connection, but it should work over existing ADSL connections.

Up to 6 handsets may be registered with the service and pricing will start at £50 pm.

Services like this reduce the reliance on a land line number, however ADSL is provisioned over a BT line, so they don't get rid of them. If Orange announce sensible pricing so calls cost significantly less than mobile when on the WiFi network there could be a large take-up.
