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 phone will now be reset.

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 ...

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

Hi,i wanna use cisco ip phone 7940 as sip ip phone.when i power up the phone ,it can get ip from network,but finally,it shows "TFTP timeout"in display led.All the buttons can not be used.What...


Hi,

the DHCP server should be providing the address of the TFTP Server as DHCP Option 150. The most likely problems are:

Option 150 not defined, or not the correct IP address of the TFTP Server.
Or possibly your TFTP Server is not functioning properly.

If you have not Option 150 defined, the phone will use the default gateway as the TFTP server address.

Cheers, Simmo99.

This happens when you IP phone communicated with the Voice vlan with the IP address of data vlan.

To solve it manually enter the IP address of the TFTP server and option 150 on the DHCP server.
remove the voice vlan from the switch port and reboot the phone
again add the voice vlan and reload the phones

I AM TRYING TO SET UP MY VOICE MAIL, BUT EACH TIME I PRESS THE MESSAGES BUTTON, ALL I GET IS A RECORDING WHICH TELLS ME TO CONTACT THE OPERATOR. SO THEN IT TELLS ME THAT THE OPERATOR IS NOT AVAILABLE.


That is because you need to setup the voice mail in Cisco Unity and also setup the phone in the call manager. Unless you have voice-mail setup it states.....Cisco Unity Messaging system....is the beginning of the message.

Upgrade firmware on a cisco ASA 5500 firewall


This is for the pixes, I haven't upgraded an asa yet...should be close or the same

* find latest version of code, these are usually *.bin files located on http://www.cisco.com/cgi-bin/tablebuild.pl/pix
* confirm the flash and RAM requirements of the PIX OS software versus what the PIX has (”sho ver”)
* make sure you have a backup of the old PIX OS and PDM to the tftp server (or at least confirm the software is there)
Note: You cannot back them up from the PIX, so you will need to download them and put them on the tftp server * put in a change control form
* once change controls confirms date/time do the upgrade:
wri mem*** only if you save your configs via tftp wri net conf t ca save all copy tftp://your tftp server ip/pix635.bin flash:imageskip this if you don't use pdm copy tftp://your tftp server ip/pdm-304.bin flash:pdm *** if this is a failover pair, upgrade the other pair reboot

Phone stuck in Configuring IP


Did you check the TFTP settings on the IP phone? You may need to disable DHCP on the phone and assign the TFTP manualy or make sure the correct TFTP server is assigned.
