Product Overview

The D-Link DPH-128MS IP Phone is part of the VoiceCenter system, designed for small to medium-sized businesses. It offers IP-based telephony with features like voice-activated dialing, voicemail-to-email forwarding, and 3-way conferencing. The phone is easy to install and manage, with two Ethernet ports for network connectivity and daisy-chaining a PC.

Installation

Installation involves connecting the IP phone to an Ethernet switch, either via a standard connection or Power over Ethernet (PoE). The phone can then be configured using the Microsoft Response Point Administrator software, where users and phone names are assigned.

Setup through MENU/Keypad

Users can also configure settings directly through the phone's menu system, including system settings, network configuration, and VoIP/SIP settings. Administrator mode requires a password (default '123'), while user mode has limited access.

Troubleshooting and error codes

Problem	Solution
There is no DIAL tone.	Check for any loose connections.
Why can't I dial my friend’s SIP number?	Check Registrar Server Domain Name/IP address and Outbound Proxy Domain Name/IP Address (under SIP Settings in Configuration Menu). Check the LCD display for name/number. Use web browser to check configuration menu. Check register status under SIP Account Settings. Contact SIP service provider if unregistered.
I accidentally set DSL to enable and now the phone does not boot up?	Unplug the power cord, wait 2 seconds, plug it back in. Press and hold MENU key. Bypass boot up and go to phone setup menu. Modify setting and save.
Why do I get “Can't Upgrade Now” screen when I click Submit in the configuration menu?	Make sure you exit setting mode (phone book, menu, speed dial...) before you click Submit in the configuration menu.
