Operations for Outgoing Calls
Monitoring Your Internal Calls and
Subsequent Services
When you establish an internal call, your extension displays your
party’s status as one of the following:
FREE • The party you are calling is free.
RING • The party you are calling is already being rung by a third party.
WAIT • The party you are calling is busy, but your call may be placed on
camp-on (multi-line extension).
BUSY • The party you are calling is busy, and it is not possible to place
your call on camp-on (single-line extension).
CONGESTED • The line you are calling is congested, therefore it is not possible
to place your call on camp-on.
If your party is free, his/her extension will be rung, while you hear
the ringback tone.
If your party is busy, your call may be automatically camped-on for
the dialled extension, and you will hear the automatic camp-on tone.
You may then simply wait for your party to answer.
To proceed with your call, in terms of the requested internal party’s
status, you may also:
• Activate the automatic call-back feature for the called extension
that is busy, or not answering.
• Broadcast a voice message on the free extension, if it is equipped
with a loudspeaker.
• End your call by sending a mini-message to the called extension,
if it is compatible with this service. See the “Message Services”
section.
Depending on the rights assigned to your extension, you may also
carry out an intrusion upon the current call on the requested exten-
sion, or override their Do not disturb status. These last services are,
however, usually reserved for your system’s attendants. See the
“Attendant-Based Services” section.
