USING NETWORK SERVICES
The NIU supports call forwarding, call waiting, three-way calling, voice
mail, and data and fax services. You can use these features if they are
offered by your service provider.
Call forwarding
The NIU is configured to support the following call forwarding features:
• Call Forwarding Unconditional (CFU) allows you to automatically reroute
all incoming calls to a different number.
• Call Forwarding Busy (CFB) allows you to automatically reroute calls to a
different number when you are in the middle of a call.
• Call Forwarding No Answer (CFNA) allows you to automatically reroute
calls to a different number when you do not answer the phone.
NOTE
Call forwarding features are service provider-dependent. Check with your
service provider for more information.
Call waiting
The NIU supports call waiting. Call waiting allows you to receive an
incoming call without terminating a previous call that is still in progress.
➤ To put the first call on hold while answering the second call,
momentarily press the hook switch or the flash key.
➤ To return to the first call, press the hook switch or flash key again.
Repeat this action to continue switching between calls.
NOTE
Pressing the hook switch momentarily (for less than 1.5 seconds) will
activate this feature. Pressing it for more than 1.5 seconds will terminate the
call.
Three-way calling
The NIU supports three-way calling. This feature allows you to initiate a
second call without terminating the one in progress, and to bring both calls
together after the second call is established.
