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.

Cisco IP Phone 7940 and 3com nbx as 3rd party SIP phones


Here are the instructions for configuring these units for 3cx

Since the 3cx softphone worked well, I don't see why you couldn't configure each as for 3cx and make them work as well.

Cisco ip phone 7940 does not ring for incoming calls.


It sounds like you have enabled Do No Disturb accidently. This can be turned on and off by pressing the DND softkey button along the bottom of the LCD display. You might need to press the 'more' softkey to display all options.

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.
