DPH-300SEOL EOS
Description
INTERNET OR TRADITIONAL PSTN PHONE FROM THE SAME CORDLESS HANDSET
The DPH-300S is a dual-mode IP phone that provides IP telephony and traditional phone connection in a single handset. It allows you to take advantage of your DSL/cable modem connection to make inexpensive Internet phone calls. This cordless phone operates in two modes: it is a normal DECT cordless phone when you connect it to an ordinary PSTN connection, and it is an IP phone when you connect it to the Internet through broadband. Because the DPH-300S has embedded VoIP functionality, you don’t need to use your computer and microphone to make IP calls - unlike PC-based softphones such as Skype.
RELIABLE CONNECTION & CLEAR VOICE
The DPH-300S delivers superior call quality with features that include voice activity detection (VAD), comfort noise generation (CNG), silence suppression, echo cancellation, adaptive jitter buffer, and lost packet recovery. It combines the industry’s latest Voice over the IP network technology with advanced communication features, and is compatible with industry-wise phone service.
SURF INTERNET WHILE MAKING INTERNET PHONE CALLS
The DPH-300S provides an Ethernet WAN port to connect to a DSL modem, cable modem, or to your broadband router. Once connected and logged on to the Internet, you are ready to make and receive calls. In addition, it provides an extra LAN port for connection to your PC’s Ethernet interface. This allows you to talk on the IP Telephone while browsing web sites, send e-mail, transfer files and do other network tasks.
QUALITY OF SERVICE AND SECURITY
The DPH-300S supports voice VLAN to isolate your voice communication so it cannot be tapped over the network. It provides priority queues to streamline traffic so web browsing and Internet download will not interfere with voice traffic and degrade Internet phone quality.
