Product details
The new C401 color-screen IP phone is a high-end business desk phone, featuring a smart LCD and DSS key mapping to increase business users’ productivity at a cost-effective price.
DSS key mapping is intelligently designed to support dynamic use as a replacement for expansion modules. Seven DSS keys correspond to the color LCD display to provide dynamic Line/DSS/BLF functions across up to four pages, for a virtual total of 28 DSS keys. Users can configure/customize each DSS key on each page. Each DSS key has a green, red, and yellow LED indicator to reflect the key status. A page shortcut button is also designed to let users switch quickly between pages. The C401 is the most cost-effective choice for SMB offices and business supervisors.
The C401 inherits all the features of business phones, such as HD voice on the handset, headset, and full-duplex speakerphone modes, PoE, Fast/Gigabit Ethernet, QoS, secure transmission, auto-provisioning, and more.
The C401 is an ideal office productivity device for business users. The old DSS key labeling is inconvenient and not environmentally friendly. The C401’s intelligent DSS key mapping gives users the flexibility to change DSS key definitions and display through simple configuration. In addition, its intelligent DSS key design can multiply as expansion modules to save space and cost. The C401 will provide the best user experience for advanced business users.
