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.

Could be a bad hook switch on the phone if you plug a different phone in does it work as it should?

This process should work for you http://www.cisco.com/en/US/products/hw/phones/ps379/products_tech_note09186a0080094584.shtmlCisco Telephone Power Brick

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 ;-)

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.

The assumption is you are using Unity connections.

Complete these steps in order to change the speed:

1. In Cisco Unity Connection Administration, find the user account or template that you want to edit. On the Edit menu, click Playback Message Settings. Set the Message Speed to Normal.
   
2. If the users make any changes while they listen to voicemail, they are saved. In order to disable this, you can go to Advanced > Conversation > Save message playback Volume and Speed. Uncheck this to ensure that the changes made by users are not saved permanently.
   

If you are not an administrator, you can press 4 or 6 during the message to speed up and slow down.
