The DPH-400S/SE Broadband Internet IP Phone allows you to take advantage of your DSL/cable modem connection to make inexpensive Internet phone calls. It combines the industry’s latest Voice over IP network (VoIP) technology with advanced communication features, and is compatible with industry-wide phone services. D-Link combines the qualities of a traditional desktop phone with all the advantages of VoIP technology to create a modern designed phone ideal for the home or office.

The DPH-400S/SE incorporates Quality of Service (QoS) to ensure that the voice received through the Internet is the same as – or even surpasses – that received on an ordinary phone. Functions such as Voice Activity Detection (VAD), Silence Suppression, Packet Loss Concealment (PLC), and other features enhance the quality of voice communication, providing quality in sound and performance.
