Intercom call settings effect when other co-workers call you from phone to phone. You can either have your phones ring or be hands free when a co-worker calls you. 

Steps for changing intercom call settings: Ring Mode
  • To set your phone to ringing operation dial 723, you will hear conformation tones and see “signaling” in your display.
  • Press the speaker phone button to hang up.
  • Now when a co-worker calls you, your phone will ring, you will know which co-worker is calling and you and you can lift the handset to speak with them.

Steps for changing intercom call settings: Hands-Free Mode
  • To set your phone to hands-free operation, dial 721, you will hear confirmation tones and see “voice call” in your display.
  • Press the speaker phone button to hang up.
  • Now when a co-worker calls you, your phone will beep and will automatically enable your speaker phone so you can simply speak back to them hands-free.

To go back to a ringing mode, dial 723, you will hear a conformation tone and see “signaling” in the display.  Press the speaker key to hang up and now you are back to normal ring mode.
