Check with your System Manager to be sure your voice
terminal is administered correctly.
Make sure that the handset and line cords at your voice
terminal are securely connected at both ends.
Find a working voice terminal of the same type as your
own. Unplug this voice terminal from its modular wall
jack. Plug your voice terminal into that jack and check if
it gets dial tone.
If your voice terminal still does not work, plug the
working voice terminal (of the same type) into your
modular wall jack. If the working voice terminal has
dial tone, your own voice terminal is faulty. See your
System Manager.
Set the ringer volume to a higher level.
Place a test call from another extension to
your extension.
Check the line cord to make certain that it is securely
connected at both ends.
If there is still a problem, see your System Manager.
