Until now, if you were looking for a clamshell-style WiFi VoIP phone, you were out of luck. But D-Link changes all that with its DPH-540, a phone that lets you make free calls anywhere you can find a WiFi hotspot. This one has a soft phone on board from global Internet telephone provider TelTel, whose calls are routed over the public SIP telephone network. The unit has features you'll find on most cellphones, with multiple ring tones and a color LCD display, and you can also access your e-mail from it. Available this summer, the phone will retail for under $300.
