restart the phone.
The phone will also display this message if you have configured it for DHCP but the DHCP server
is incorrectly configured. This is an unusual situation, because administrators take great care to
ensure that the DHCP servers are correctly configured.
4.2.5.6 Prohibition on Making a Call
When there is one or more of the problems listed above, the phone flashes the LEDs orange on
the Call buttons. It flashes the first button for 250 ms, then the second for 250 ms, and so on, to
give the appearance of a “walking” pattern. The LEDs on the call buttons remain in this state, the
call buttons are inoperative, the phone does not provide dial tone, and you cannot make any calls
until you have resolved the problem.
