The SIP-based 400 series IP phones are available in two models, IP480g, and IP485g, ranging from a basic phone to a more advanced backlit color display phone. The 400 series phones have superior sound quality on the handset and speakerphone, multiple line appearances, an ergonomic design, easy to read display, and convenient access to features including voice mail, directories and conferencing.


Phone Display

The display screen on your IP phone shows your name and extension, availability state, call appearance buttons, workgroup agent status, programmed buttons, and other information.

Call Appearance Buttons and Programmable Buttons

Eight custom buttons with tri-color LED indicators show active, incoming, and on-hold calls. They can also be configured as monitored extensions, speed dial keys, or other functions.

Soft Keys

Your phone includes five soft keys whose function changes depending on the state of your phone. For example, if your phone is idle, the soft keys let you modify settings such as your availability state or phone options. If you have an active call, you can use the soft keys to do such things as hang up, park the call, or merge the call with another call to create a conference call. When the label on a soft key is underlined with a dotted line, you can press the selector button on the navigation key pad to perform the function identified on that soft key.

Audio Control Keys

Volume button controls handset, headset, speaker, and ring volume. Headset, Mute, and Speaker buttons are illuminated when functions are active.

The navigation key pad and selector button allows you to navigate and select different options within the display interface.  The Function Keys perform core telephony functions such as:

  • Voicemail
  • Directory
  • History
  • Transfer
  • Conference
  • Hold
