Picked up this at HN in City West - ordered online but I think you might get it in store too:
The Telstra 9750BT twin handset cordless phone operates in a dedicated DECT frequency band and will not interfere with other Wi-Fi products. It also features Bluetooth call connectivity to make and receive mobile calls.
DECT and Wi-Fi Friendly
The Telstra 9750BT twin handset cordless phone features Wi-Fi friendly DECT technology easily integrating into homes with Wi-Fi and internet services because the frequency is exclusive to DECT, making it interference free for cordless communications.
Bluetooth
With built in Bluetooth connectivity, the Telstra Long Range 9750BT allows you to connect up to 4 mobile phones to make and receive mobile calls. This allows calls to be made using either your home line or mobile network from any Telstra Long Range 9750BT handset.
Digital Answering Machine
Select the messages and important calls to keep. Enjoy cleaner-sounding messages and 100 minutes recording time.
Hardly normal Price on the box was $219 but you can get them online much cheaper. Good deal!
Wasn't this the same one on sale last time at TGG for $48?
