A programming option is available that disables the warning tone when barge-
in is activated. See page 98 for programming from the web application and
Page 164 for programming from the programming Featurephone.
A further option is provided to protect extensions from "Barge-In". See page
104 for programming from the management application and Page 163 for
programming from the programming Featurephone.
If an attempt is made to barge-in on a protected extension the display shows
"Barge-In Prohibited".
If barge-in is unsuccessful for any other reason the display shows "Barge-In
Failed".
Barge-in is not allowed if the extension selected is not on a call, is
transferring a call, is listening to voice mail or is in a three way
Note
conference call.
A maximum of three simultaneous barge-in and conference calls
are allowed in the system.
Note
From a standard analog or cordless telephone, dialing the code 709 followed
by the extension number, activates "Barge-In".
Call Waiting from another extension
If you get a busy tone, when you call an extension, you can alert the busy
extension that you wish to contact provided the extension is not protected
against receiving Call Waiting tones. (See 'Call Waiting Tone Protection' on
page 163). An audible tone will sound on the called extension, and the
message 'Call wait. – Ext xx' will appear on its display. Options to accept the
call are offered on the display.
To present a busy extension with a Call Waiting tone
Select 'Waiting tone' on the display when a busy tone is returned from an
extension.
From a standard telephone, the code is Hookflash 8.
To accept a waiting call
If another extension presents you with Call Waiting, this will be indicated on
your display and you will hear the Call Waiting tone, provided your extension
is not protected against Call Waiting tones.
Select one of the options presented on the display.
If you ignore the Call Waiting tone for a short period the Call
Waiting offer is rejected and the calling telephone is presented
Note
with the message 'Call Waiting Rejected'.
Call Waiting from external calls
If you are on a call and your extension is presented with an external call you
will hear a call waiting tone provided your extension is not protected against
call waiting tones.
