4. Overview
The D-Link DPH-80 is a low cost, simple to use and extremely versatile IP phone with
the look and feel of a normal PSTN phone.
The D-Link IP Phone can operate under any of the three main Internet telephony
protocols: Media Gateway Control Protocol (MGCP); Session Initiation Protocol (SIP);
and the H.323 protocol. These protocols are used for signaling, maintaining, and tearing
down voice calls. The D-Link IP phone allows voice data to be carried over the same
path used by your computer for the Internet or Local Area Network (LAN).
The D-Link DPH-80 phone is easy to install and supports plug and play features of the
IP network. Out of the box, your IP phone will work in any of the above-mentioned
three protocol infrastructures with minimal configuration. Advanced, customized
configuration is easily achieved through a web-browser configuration utility.
D-Link IP phones support remote maintenance, allowing software to be upgraded
remotely for new features and any bug fixes. The DPH-80 supports a unique remote
diagnostic feature to monitor phone functions and performance.
