There is no response when you
press a feature key. The phone is not in an active
state. • Press the keys more slowly.
• Check with your system administrator
to see if the key has been mapped to
a different function or is disabled.
• Place a call to the phone to check that
inbound call display and ringing is
normal. If successful, try to press
feature keys within the call to access
the Main Menu, for example.

> Status > Lines >
Line Information. From the
Line Information page, verify that your
phone line is registered.

server, reboot your phone. For more

operational (flashing link/status lights)
or contact your system administrator.

inactive. Tap > Status >
Network > Ethernet. From the
Ethernet screen, scroll to LAN port
and verify that it is active.
