You'll need to buy a another power supply unless you have power over Ethernet. The power supply for 7940G/7960G is CP-PWR-CUBE and for 7941G/7945G you'll need a CP-PWR-CUBE-3. Yes, I know, I just got one of those and it's a pain to configure it, but I got it working... ;-)

P.S. If you haven't notice, you will be dealing with a whole different thing, the configuration/settings will ALL (except for the dialplan file) different from the 7940G... Good Luck ;-)

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.


Please use the link below and follow the instruction http://www.firewall.cx/downloads/cisco-tools-a-applications/cisco-ip-phone-a-ata-firmware-downloads.html

Cisco 7945G keeps rebooting after factory reset


If you used the traditional keypress sequence where you hold down the * key, reboot the phone, and then press the keys in sequence, you may be stuck in a boot loop. You might need to connect your phone to a network if your phone is trying to reach a TFTP server to fetch a firmware or config file update. If you need a power supply, you might try CiscoPowerCube.com they sell a cross compatible version of the CP-PWR-CUBE3 which includes the cord.

7940 cisco ip phone being powered by a power brick seems to loose power when connected to the ethernet. When ethernet is disconnected, power comes back. Ethernet works fine when phone is not connected. No...


Change out your cable from the wall drop to the phone. A Cisco phone is capable of receiving inline power (Power Over Ethernet) via the blue and brown pairs of the cable. It sounds like you may have a cable with a short in either the brown or blue, or both pairs, shorting out the power when it is connected via ethernet.

If you can, have your IT Tech check the cable, and the line through the wall to the switch.

Cannot program Speed Dial


Try adding Cisco 7914 (time two) for additional (other) phone lines, or define caller group so phone call rings around.
