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.
Ring tones, a green flashing call appearance button, and the flashing red light in the top right corner of your phone indicate an incoming call. If the information is available, the caller's name and number appear in an incoming call window on your display.
To answer a call, you can use the handset, the speakerphone, or a headset. Depending on how you set your automatic off-hook preference, you can also answer a call through your speakerphone or headset using either of the following methods:
- Press the blinking green call appearance button.
- If the incoming call is shown in the focus window on your phone's display, press the Answer soft key.
