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.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 websites, send e-mail, transfer les and do other network tasks on your PC.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.
