What is VoIP?

Voice over Internet Protocol is the ability to make and receive voice phone calls over an IP based network. This includes a Local Area Network and a public IP network such as the Internet. The technology has been around for many years but mostly at big business level who used their large network capacity to also carry voice phone calls.

With this Internet telephone, expensive long-distance and international phone calls over the ordinary telephone can be avoided altogether. You make and receive voice calls over the same line that you use to connect to the Internet, and pay the same Internet connection charge, plus a service charge to your Service Provider.

The DPH-120S operates just like any ordinary telephone. All destination numbers must be registered with your Internet Telephony Service Provider or Proxy Server. It 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 telephone 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.

Note: You must choose an Internet (VoIP) Phone Service Plan and sign up for service. VoIP phone plans, rates and features may vary depending on VoIP Phone Service Provider(s).
