The DPH-120S operates just like any ordinary telephone. All destination numbers must be registered with your Internet Telephony Service Provider or Proxy Server.
The DPH-120S has a built-in Ethernet interface to connect to a DSL or cable modem, or a router supporting DSL or cable modem connection.
The DPH-120S can also be used with LANs with Ethernet and IP protocol support. Voice is transmitted on the same line with data, and telephone charges are eliminated altogether.
The DPH-120S incorporates acoustic echo cancellation, voice activity detection/comfort noise generation (when there is a prolonged silence), and adaptive jitter buffer.
Voice and data travels at the same time on the same network line. The DPH-120S provides an extra RJ-45 connector that connects to your PC's Ethernet interface. This allows you to talk on the IP Telephone while browsing web sites, send email, transfer files and do other network tasks.*
The DPH-120S is a speakerphone. It has a large LCD to display dial-out and call-in numbers. It also has redial, mute, transfer, voice mail, 3-way conference, call waiting, call forwarding and hold functions, plus a menu key and an address book.
* Voice quality may be affected if large file transfer occurs at the same time.
