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

the first problem will be to check or replace the cable that you use to connect the phone or check the jack that you use

The phone will soon display “Reset key sequence detected”
3) After several lights flash press the following keys in order:

If that process fails to work for some reason there
is a second method.

Try configuring CCM IP address either trough DHCP parameter, or Network configuration on the phone.

SOURCE: 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.

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.

My cisco ip phone 7960 is stuck in boot up mode after performing the soft reboot. i press 123456789*0#


You can try a couple of things: Unplug the power cable from the phone, hold dows the # key, and then plug the power cable in again. The phone begins its power up cycle. Release the # key after the Speaker button is no longer lit. You should see the following message on the phone: "Reset key sequence detected" Press 123456789*0# within 60 seconds after the Headset, Mute, and Speaker buttons begin to flash. If you enter this key sequence correctly, the phone displays this prompt: Keep network cfg? 1 = yes 2 = no In order to maintain the current network configuration settings for the phone when the phone resets, press 1. In order to reset the network configuration settings when the phone resets, press 2.
Or to perform a full reset: Press **#** to reset the Cisco IP Phone 7960

Phone does not boot , what can be the cause of this ?? I have tried to use different cables on the phones but none seem to work, I have also tried to reset the phone back to its factory state but nothing...


If you are sure your network is setup properly; and the voice vlan is properly setup; it's probably a bad phone. You could try cisco TAC for support. I would double check that the MAC address of this particular phone is correct with the bootup provider.
