The D-Link DPH-540 is a Wi-Fi flip-style handset that comes preloaded with TelTel VoIP software, a free application that relays SIP calls across a managed peer-to-peer Internet telephony backbone. The DPH-540 uses SIP (Session Initiation Protocol), so it’s a non-Skype phone.

D-Link DPH-540 features and specifications:

* 900mAh battery
* 802.11b/g-class radio
* 12MB SRAM and 16MB Flash ROM
* 40-voice polyphonic ringtone engine

From the news release:

D-Link, the leading end-to-end networking solutions provider for consumers and business, today introduced the industry’s first flip-style mobile Wi-Fi phone that will ship with a full-featured softphone from TelTel, provider of SIP-based global Internet telephony services, allowing users to make free calls anywhere in the world where there is open Wi-Fi access.

Update: D-Link DPH-540 and DPH-541 now shipping

D-Link has announced that it has begun shipping its WiFi flip phones, the DPH-540 and the DPH-541. From the news release:

D-Link, the end-to-end networking solutions provider for consumers and business, today began shipping its flip-style Wi-Fi Phone that combines the cost-savings of Voice over Internet Protocol (VoIP) technology with 802.11 wireless connectivity in a compact Session Initiation Protocol (SIP)-based package. The sleek portable D-Link Wi-Fi Phone, together with an Internet VoIP phone service, provides both consumers and businesses a stylish way to dramatically reduce local and long distance telephone charges compared to standard telephone service. VoIP phone calls can be made where there is a Wi-Fi network or open hot spot to the Internet — without the use of a PC.

“We are pleased to announce immediate availability of the D-Link Wi-Fi Phone to the thousands of consumers and business customers that have been anxiously awaiting the product since we demonstrated a prototype at the VON show this past spring,” said Steven Joe, president and CEO of D-Link Systems, Inc. “Our phone is truly a first of its kind in both design and functionality, and the potential cost savings to be realized from this type of device are astounding. This product will act as a flagship for D-Link in this key emerging market, complimenting our popular wireless networking and VoIP telephony solutions.”

Weighing only 3.74 ounces in a compact clamshell design, the phones feature large, bright color displays for easy viewing of numbers as they are dialed, storage of up to 100 address book entries, caller ID and polyphonic ring tones with seven-step volume control, as well as support for redial, mute, hold and text messaging. Users can expect about three hours of talk time and 70 hours of standby time on a single charge of the Li-Ion, 900mAh battery. An external power adapter and mini-USB cable are included.

The D-Link Wi-Fi Phone has the same look and feel of a flip-style cell phone, but is based on 802.11 wireless and VoIP technology. To make and receive calls, users need only an 802.11b, g or n wireless network with high-speed Internet access.

In addition, the phone, which uses a Broadcom chipset for low-power consumption and a small footprint, offers echo cancellation, packet delay compensation and lost packet recovery, resulting in similar or improved voice quality over traditional phones. The D-Link Wi-Fi Phone uses the popular SIP technology and is ready to be used with many VoIP service plans.

For accessing secure wireless networks, the Wi-Fi Phone supports WEP, WPA and WPA2 encryption.

D-Link’s new Wi-Fi Phone is compliant with Public SIP Telephone Network (PsipTN), the telephony technology expected to be available in the third quarter this year. Users will be able to make and receive free calls within the network via a firmware upgrade and a one-year subscription. PsipTN also allows users to receive calls from regular phones for free.

To take full advantage of the convenience and money-saving features of D-Link’s new Wi-Fi Phone and make calls to standard landline or cellular phones, users must select an Internet (VoIP) Phone Service Plan and sign up for service; rates and features may vary depending on the service provider.
