You need to ensure that each port that has a phone plugged into it is configured with power over ethernet configured switched on.

SOURCE: Converting Cisco 7940 IP Phone to SIP

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.

You are very close to fixing your problem. You will need the correct firmware and files; these are proprietary but you should be able to acquire them from your certified reseller. Alternatively, here at IdacomUSA, we have the proper firmware on hand, and can flash the phone for you to get it back to life. Call us at 1-800-903-9190 or visit us at http://idacomusa.com

Cisco 7942 factory reset


When performing the factory reset procedure we are about to describe, it is important to keep in mind that the IP phone will lose all configuration files and phone applications. This means that it is necessary to have CallManager or CallManager Express setup so that the IP phone will be able to receive the new information (phone application and configuration) after the reset procedure is complete, otherwise it is most likely that the IP phone will not be usable until this information is loaded on to it.
This preparation also happens to be the procedure for upgrading a Cisco IP phone firmware.



Follow the steps below to successfully factory reset your Cisco 7942, 7962 IP phone:
  1. Unplug the power cable from the phone and then plug it back in. The phone begins its power up cycle.
  2. While the phone is powering up, and before the Speaker button flashes on and off, press and hold #. Continue to hold # until each line button flashes on and off in sequence in amber.
  3. Release # and press 123456789*0#.
You can press a key twice in a row, but if you press the keys out of sequence, the factory reset will not take place.
After you press these keys, the line buttons on the phone flash red and the phone goes through the factory reset process.
Do not power down the phone until it completes the factory reset process and the main screen appears.

My Cisco IP Phone 7945G keeps rebooting after I did a factory reset. Is there a way to fix this?


According to Cisco, when initiating a factory reset procedure certain information from the IP phone is erased while other information is reset to the factory default value, as shown in the list below:


Information Erased:
  • CTL File (Certificate Trust List)
  • LSC File (Locally Significant Certificate)
  • IP Phone Call History (Calls Received, Placed, Missed etc)
  • Phone application
Information Reset to Default:
  • User configuration settings (ring tone, screen brightness, sound levels etc)
  • Network configuration settings

t is highly advisable to follow the firmware upgrade procedure in a non-working environment to ensure other phones are not affected (in case of an accidental reboot), and to avoid the freshly factory reset ip phones obtaining the working environment's settings.

We are experiencing some NW problems with our Cisco 7940 hardphones. We have several installed and for some time now it seems that these hardphones just lose their default gateway configuration and stop...


I would check the firmware on the phones. Also, check that your switches are properly configured. Duplex settings do matter. If your using cisco switches; do a "show interface" and check for CRC errors etc.

I would verify what the firrmware is of the phone. It is possible that the phones need to be upgraded.

My client has Cisco 7940 IP phones and wants assistance with feature programming


This phone can be access through a menu/ setting buttons.

Useful link on how to navigate through the phone:
http://www.cisco.com/warp/public/779/largeent/avvid/products/7940/7940_topic3.htm
I think the main problem is to determine the intergrated router or Call manager configuration
You can also connect on switch and type:show cpd neighbor This will show the physical port connections
