Call Handling Basics
Dialing Telephone Numbers
You can dial an internal extension number or the number of a
telephone outside the system. Either the Source or Destination
areas must be clear.
To call an extension
1. Dial the extension number from the console keypad.
Information about the extension appears in the Destination
area. If information about an answered call is currently in the
Destination area, that information moves to the Source area
as soon as you start dialing.
2. Press Release
to release the call. If the extension is busy, the transferred
call will automatically camp on to the line to wait until it
becomes free. You can also handle the call in one of the
following ways:
If the extension is busy
• Press [Source]
and ask what the Source party would like to do. This leaves
the Destination information displayed so that you can easily
take a message and set Message Waiting on the destination
extension, if required. (See Message Waiting on page 37.)
Or
• Press Cancel
to cancel the call. The caller remains in the Source area, but
the information in the Destination area is lost, which makes
setting Message Waiting more difficult.
Or
• Press [Override]
to intrude into the Destination party’s call if permitted by
your and the extension’s Class of Service (see Override on
page 38).
To call an outside number
1. Dial the External Line Access Code ( ______ ) * .
2. Dial the telephone number.
Information about the outside call appears in the
Destination area.
Leaving a Callback
You can request a Callback after reaching a busy line (extension
or trunk). The system monitors the line and rings the console
when the line becomes free. Note that Callbacks on outside lines
are used when all system trunks are busy, not when the called
party is busy.
To leave a Callback after reaching a busy line
• Press [Callback].
Placing an outside call for an extension
Extension users can usually place their own calls. However, they
could ask you to place a call for them. Before dialing, you may want
to note the extension’s COR number (see Class of Restriction on
page 62). Check with your communications department for specific
instructions on how to handle such requests.
To place an outside call for an extension
1. Answer the call from the extension.
2. Dial the External Line Access Code ( ______ ) * .
3. Dial the telephone number.
4. Press Release
to release the call from the console and connect the extension
to the outside line.
* Use this space to record the digits you dial to access
an outside line.
