Superior Voice Quality
The DPH-120SE IP phone incorporates Quality of Service (QoS) to ensure that voice received through the Internet is the same as or even surpasses that received on the ordinary phone. It supports many useful functions such as call transfer, caller ID display, 3-way conference and speed dialing to make it convenient to dial out or answer phone calls.
Surf Internet While Making Internet Phone Calls
The DPH-120SE comes with two Ethernet ports, one to connect to a DSL or cable modem, or to your broadband router. Once connected and logged onto the Internet, you are ready to make and receive calls. In addition, this IP phone provides another Ethernet port for connection to your PC, so you can talk on the IP telephone while browsing web sites, send e-mail, transfer ¬les and do other network tasks on your PC.
Quality of Service And Security
The DPH-120SE supports voice VLAN to isolate your voice communication so it cannot be tapped over the network. It provides priority queues to streamline tra c so web browsing and Internet download will not interfere with voice tra c and degrade Internet phone quality.
