The S4G network phone is an enterprise-grade color-screen network phone featuring intelligent side screen keys. It supports 4 SIP accounts, comes with a 2.8-inch true-color LCD display, 4 programmable soft keys, and built-in POE. Equipped with HD voice, a headset, and a full-duplex speaker with high-performance echo cancellation, it offers users an immersive auditory experience. Meanwhile, the flip-style paperless programmable keys enable users to achieve efficient office work more easily, providing convenient and quick communication experience for business office staff and managers with heavy call loads.

The new DSS key design combined with a dynamic intelligent display can replace the function of traditional expansion boards. The S4G phone is equipped with 7 DSS keys, each corresponding to the color LCD display, so as to provide up to four pages of dynamic line/DSS/BLF functions at a total of 28 virtualized DSS keys. Users can configure/customize each DSS key on every page. Each DSS key is equipped with an LED indicator that can turn green, red, and yellow to reflect the status of the DSS key. Page shortcut buttons are also designed to allow users to switch between pages quickly. It is an economical choice for SMB office and enterprise managers.
