2.10.4.2 Call Waiting Tone
Description
When an extension user attempts to call a busy extension (ringing or having a conversation), the Call Waiting
tone can be sent to the called extension to let him know another call is waiting.
Conditions
• This feature only works if the called extension has activated Call Waiting. If it is activated, the calling
extension will hear a ringback tone.
• Call Waiting tone can be selected (Tone 1 or Tone 2) through personal programming (Call Waiting Tone
Type Selection).
• When the headset mode is on, you can choose whether the call waiting tone is heard from the speaker
phone of the telephone or the earpiece of the headset. However, this setting is only available for terminals
that support call waiting tone path switching (KX-DT521, KX-DT543, KX-DT546, KX-NT553, and
KX-NT556).
