Unlocking a Cisco 7940

Method 1:
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.

Method 2

Complete these steps:

1. Press Settings.
2. The Network Configuration lock symbol must be unlocked. If not, exit to the main window and press ** # again.
3. Press 3 on the keypad (or scroll down) for Network Configuration.
4. Press 33 on the keypad (or scroll down) to Erase Configuration.
5. Press the Yes softkey.
6. Press the Save softkey.

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 :)

Hi,

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 ...

ephone-dn 30
number 8000...
mwi on
!
!
ephone-dn 31
number 8001...
mwi off

and also mapped to each phone to enable MWI status

ephone-dn 1 dual-line
number 111
label Chris
name fred
call-forward busy 800
call-forward noan 800 timeout 10
huntstop channel
mwi-type visual

Complete config details are at:http://www.ciscosystems.com/en/US/docs/voice_ip_comm/cucme/command/reference/cme_m1ht.html#wp1018439

If this helps pls leave feedback
