D-Link has introduced its Wireless G Flip-Style Wi-Fi Mobile Phone: If they worked at it, they might slip a few more words in its name. The DPH-540 uses 802.11g (which is a bit rare for a VoIP phone), handles WPA-PSK (also a bit rare right now), and uses standard SIP (Session Initiation Protocol) which works with many VoIP providers—although getting the SIP gateway details is sometimes problematic.
The phone is 3.74 ounces, color backlit LCD display, and all the expected real phone goodness like speed dial and ring tones. The software is from TelTel, which handles buddy lists, TelTel-to-TelTel (T5?) calling (free) and PSTN calling (fee).
The marketing material notes that you can “Call Anywhere in the World Wherever you Have a Wireless Connection” but doesn’t mention that most hotspots use authentication—not WPA Personal. This is a growing issue that will be addressed in Wi-Fi phones meant for real hotspot roaming, rather than this, which is great around the house or at some free hotspots (those that don’t have a gateway page to confirm use on before access).
The phone will be shown at the VON (Voice Over Network) this week (tomorrow through Friday). It will ship this summer via retailers for $250 (list).
Edith Cowan University plans to replace 200 mobile phones with VoWLAN phones: They expect a savings of AU$200,000 per year, half their mobile bill. The campus-wide Wi-Fi network is already in place—using Nortel mesh gear—and thus their only incremental cost is handsets.
