Netgear has unveiled the first Skype handset that enables users to place phone calls without a computer. 

Skype handsets using USB cables or a Wi-Fi connection have been available from a range of vendors including Taiwanese firms Wistron and Accton. But they all require software running on a computer.

The Netgear model is the first to allow users to place phone calls without the need for a PC by connecting directly to a router.

"This is the first time that it is possible to use Skype on a cellular phone without a PC," said Skype chief executive Niklas Zennström, who dropped in to a press conference at the Consumer Electronics Show in Las Vegas to demonstrate the new phone.

Netgear chief executive Patrick Lo said at the event that the phone will be shipping worldwide before April this year. He did not provide pricing information.

The phone requires a free access point, but Lo speculated that future versions might include support for commercial Wi-Fi services like those offered by T-Mobile.

The collaboration between Skype and Netgear will also allow Netgear to enable its routers to prioritise the delivery of Skype VoIP traffic.
