Call Waiting

Call Waiting (#316) 4
Use this feature to activate Call Waiting. When you are on a call and a second intercom, transferred, or outside call comes in, you hear two beeps to indicate you have a second call waiting to be answered. Press the switchhook (or Recall or Flash button, if available) to put the current call on hold and retrieve the second call. To return to the first call, press the switchhook again.
