3com 3101 Manuel D’Utilisation

When your telephone is in Do Not Disturb mode:

■

Your telephone does not ring when it receives an incoming call.

If you use an NBX Business Telephone or an NBX Attendant Console, the 
associated status light does flash when a call arrives.

■

You can use the telephone to dial outgoing calls.

■

You can use the telephone to dial internal and external pages.

■

An NBX Business Telephone does not broadcast incoming paging 
messages over the speaker.

■

If your telephone is part of a call pickup group, no other telephone in 
the pickup group can retrieve a call that comes directly in to your 
telephone. The incoming call goes immediately to the call coverage 
point (voice mail, auto attendant, or other extension).

■

If your telephone is part of a hunt group, incoming calls to the hunt 
group ring on your telephone. Calls coming in directly to your 
telephone (not directed to the hunt group) do not ring on your 
telephone. To prevent every call from ringing, you must enable Do Not 
Disturb and also log out of the hunt group.

To enable and disable Do Not Disturb using the feature code:

1 Pick up the handset and press Feature + 446.

2 Hang up. Your telephone is now in Do Not Disturb mode. The display 

panel on an NBX Telephone shows DO NOT DISTURB.

3 To disable Do Not Disturb mode, repeat steps 1 and 2. The DO NOT 

DISTURB message disappears from the display panel.

To prevent others from dialing long-distance or other unauthorized calls 
from your telephone permanently, ask your administrator to adjust the 
call permissions schedule for your extension, or you can adjust it 
temporarily with the Telephone Locking feature.
