Configuring Supplementary Services

Supplementary Services controls a number of features that are listed in the User
window that you can enable or disable. To display the Supplementary Services
features, choose the Voice tab and click the User menu. Choose yes to enable or
no to disable a feature. When the modifications are complete, click Submit All
Changes. Your phone reboots.
You can also enable or disable these features from your phone.
The Supplementary Services are described in the following sections.

Call Waiting (CW Setting)

Use call waiting to alert you by displaying a status message and ringing your
phone while you are on a call to indicate that another call is incoming. If you turn
call waiting off, incoming calls do not ring your phone while you are on another call,
and the caller hears a busy signal or message.

Block Caller ID (Block CID Setting)

Use this feature to prevent the caller ID information from being sent by your phone;
your phone number and information does not appear to the person you call.

Block Anonymous Calls (Block ANC Setting)

Blocking anonymous calls prevents calls with unknown Caller ID from ringing your
phone. For example, if a caller set his phone to not display Caller ID, the call is
considered anonymous and your phone will not accept the call. These callers
receive a busy signal or message.

Do Not Disturb (DND Setting)

Use the Do Not Disturb to prevent incoming calls from ringing your phone. If you
have voice mail configured, incoming callers are sent to voice mail. If voice mail is
not configured, callers hear a busy signal or a message.
Display Text Messages on Receiving Phone (Display Text Message on
Recv Setting)
Use the Display Text Messages on Receiving to enable or prevent text messages
from displaying on your phone.
