Possible Cause & Solution
•
The service for your telephone is turned off in the connected
PBX.
→
If the sub-display on the Calls screen or the Feature
Key screen (in Call List mode) is blank, the service status
for your telephone is turned off in the PBX. Consult your
administrator to change the service status.
•
The phone number was entered incorrectly.
→
Confirm that you have entered the phone number of the
other party correctly.
→
Consult your administrator.
•
The screen was changed during a programming operation.
Under some conditions, changing the screen without exiting
programming mode can cause the KX-NT400 to not be able
to make and receive calls. This problem can occur when
programming the telephone via the Calls screen, the Feature
Key screen (in Call List mode), or the Programming screen.
→
Wait a while for programming mode to exit automatically.
•
The number you are trying to redial is too long.
→
If the dialed number contains more than 32 digits for an
internal call, it cannot be redialed correctly.
•
Your telephone service does not allow you to make long
distance calls.
→
Make sure that you have subscribed to your telephone
company's long distance service.
•
If the KX-NT400 is connected to a PBX, your extension may
not be configured to make long distance phone calls.
→
Contact your administrator.
•
The ringer is turned off.
→
Press (UP) while a call is being received, or change the
ringer volume setting.
