MD Evolution – Dialog 4422 IP Office 30
Monitoring Your Internal Calls and
Subsequent Services
When you establish an internal call, your party’s status is displayed
on your extension, and is also signalled by one of the following audible
tones:
FREE • The party you are calling is free. His/her phone is ringing, while
you hear the ringback tone.
RING • The party you are calling is already being rung by a third party.
You also hear the ringback tone.
WAIT • The party you are calling is busy, but your call may be placed on
camp-on (multi-line extension). You hear the camp-on tone.
See also the “ Operations for Incoming Calls ” section.
BUSY • The party you are calling is busy, and it is not possible to place
your call on camp-on (single-line extension). You hear the busy
tone.
CONGESTED • The line you are calling is congested, therefore it is not possible
to place your call on camp-on. You also hear the busy 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.
• Activate the automatic call-back feature for the called extension
that is free, but is not answering.
WAIT
