IP580, a fully featured IP phone with 15 programmable buttons, offers multi-tasking users the most convenient, cost-effective, flexible and user-friendly communication desktop which supports Power-over-Ethernet via the IEEE802.3af standard. The easy-to-use interface includes the backlit LCD and 9 function keys such as message, auto-answer, DND, mute, redial, and speaker that allow users to directly execute the function they need to use.

The LCD clearly displays the extension number, name, present time, caller ID and call status. Besides, it also indicates the internal or external missed calls status like caller's name, extension number, and calling time. When the users see the steady "missed call" indication on the LCD, they can simply press the menu button for calling back or accessing into the missed call status.

Also, it is very easy to both of users and administrators to be proficient in customizing specific features on the 15 programmable buttons or editing the personal station configurations like as Button Mapping, Speed Dial, Message Option, Answer Option, Password and Phone Book through the Web-Based Administration.
