It combines traditional telephone usability with the advanced capabilities of Voice over IP, offering high-quality voice communication over your existing broadband Internet connection.

Product Features

Superior Voice Quality
Equipped with advanced acoustic echo cancellation (G.167), comfort noise generation, and voice activity detection (VAD), the DPH-120SE delivers crystal-clear audio on every call. Quality of Service (QoS) prioritization ensures stable voice clarity, even during simultaneous data transfers on your network.

Dual Ethernet Ports for Simultaneous Use
The integrated dual 10/100BASE-TX Ethernet ports allow one port to connect to a broadband modem or router and another to connect to a PC. This enables you to make or receive VoIP calls while simultaneously using the Internet for browsing, emailing, or file sharing without compromising call quality.

Advanced SIP Compatibility and Features
Built to meet SIP RFC 3261 and related standards, the DPH-120SE supports essential call features such as call transfer, caller ID display, 3-way conferencing, redial, call history (missed, received, dialed), and a local phonebook with support for up to 500 contacts. It also offers XML phonebook support and click-to-dial from the web interface for improved convenience.

Robust Security and Network Integration
Voice VLAN support enhances security by isolating voice traffic, while NAT traversal protocols such as STUN and port mapping ensure reliable connectivity across various network configurations. The phone supports auto provisioning via TFTP, FTP, or HTTP for simplified deployment and centralized configuration in office setups.

User-Friendly Interface and Controls
The DPH-120SE offers a familiar desktop telephone layout with a user-friendly interface that includes a backlit display, soft keys, customizable ringtones, call indicators, and configurable speed-dial options. It also features a password-protected settings menu for administrative control and device security.
