Unlocking a Cisco 7940
1) Unplug the phone
2) Plug the phone back in while holding the # key
The phone will soon display “Reset key sequence detected”
3) After several lights flash press the following keys in order:
1 2 3 4 5 6 7 8 9 * 0 #
4) The phone will then ask you if you want to save the network configurations:
Save network cfg? 1=yes 2=no
5) The phone will soon display “Factory reset initiated” and will continue
through the boot up process.
If that process fails to work for some reason there
is a second method.
Complete these steps:

The handsets will eventually go bad. If it is every single handset that you have, the problem is with the system. But if the problem is only with a few of your phones, you might consider replacing the handsets. We at IdacomUSA.com have replacement Cisco handsets for sale at only $25. Hope this helps you out :)

Has this just stopped working, or has it never been working?
On the call manager / CME the MWI (Message Waiting Indicator) needs to be configured. This could be undertaken either via the GUI or from the CLI
For instance ...
and also mapped to each phone to enable MWI status
ephone-dn 1 dual-line
call-forward busy 800
call-forward noan 800 timeout 10
