When an extension is programmed with Call Waiting, you hear a tone when you are off-hook and another call arrives. For an inside call, you hear one beep; for an outside call, you hear two beeps. With a 4400-Series or MLX display telephone, you also see Call Waiting on the display. The caller hears a special ringback to indicate that the extension is busy and that the call-waiting tone has been sent.

The Call Waiting feature is supplied by the MERLIN MAGIX Integrated System and is not the same as the Call Waiting supplied by the central office.

A multiline telephone is considered busy when no SA or ICOM buttons are available for incoming calls and, if Coverage is programmed, all coverage points are busy.

When the called party frees an SA or ICOM button and there is a call waiting, the caller hears dequeuing tone, and the waiting call appears on the free SA or ICOM button of the called party.

A single-line telephone is considered busy when a call rings on the telephone or the user lifts the handset and, if Coverage is programmed, all coverage points are busy.

Each extension can be programmed with Call Waiting on or off. The default is Call Waiting off.

The user hears a Call Waiting tone for the following types of calls that ring on an SA or ICOM button:

• An inside call
• A call received on a DID trunk
• A call from a Remote Access user
• A call received on an automatic dial-in tie trunk
• A call transferred to the extension
  
  

You do not hear a call-waiting tone for a call received on a Personal Line unless your business subscribes to a call-waiting service from the local telephone company.

The person receiving the call-waiting tone has these options:

• Ignore the new call and continue with the current call; the caller continues to hear the special ringback.
• Complete the current call, hang up, and answer the waiting call when it rings; the caller hears normal ringback.
• On a multiline telephone, put the current call on hold and answer the new call using an ICOM Originate Only or SA Originate Only button (if one is available) by using Call Waiting pickup. To activate Call Waiting pickup on an ICOM Originate Only or SA Originate Only button, press the Feature button followed by 87, or dial #87.
• On a 4400 telephone, press the Flash button and dial #87 to answer the waiting call.
• On a 4400D telephone, press the Hold button and dial #87 to answer the waiting call.
• On a single-line telephone without positive disconnect, put the current call on hold by pressing and releasing the switchhook or the Flash or Recall button. If the single-line telephone has positive disconnect, park the call by pressing the Flash or Recall button, then dialing your extension number. Dial #87 to answer the waiting call. To pick up a parked call, lift the handset and (while listening to inside dial tone) dial #9 plus your extension number.
