Resetting to factory defaultsRead the next section before doing this!
Step 1 Press the Menu button.
Step 2 Use the Navigation button to select Settings, and then press the Select softkey.
Step 3 Use the Navigation button to select Network Configuration, and then press the Select softkey.
Step 4 Perform either of these procedures:
* Press **2. The phone displays “Do you want to reset all system settings to default values?”
* Press the Yes softkey.
* Press **#. If your phone displays “Enter Admin Password,” enter your password and then press the Enter softkey. Make sure that an unlocked padlock icon appears in the upper-right corner of your LCD.
* Scroll to Erase Configuration.
* Press the Yes softkey and then press the Save softkey.
The phone cycles through normal startup procedures.
Problems if no default password setIf you do set your phone back to factory defaults, it may have a blank admin password (the ‘UIPassword’), in which case you can no longer change the phone’s settings from the Web interface! The only way to re-setup the UIPassword is via TFTP, which means you need to have a tftp server running on your network. A very useful, free, Windows-based TFTP server can be found here: TFTPD32
In order to re-setup the UIPassword, your TFTP server must present the file gkdefault.cfg (7912) or lddefault.cfg (7905) to the phone as it boots (in fact, the parameters placed in these files are picked up by ANY 7912/7905 as they boot.) The contents of the .cfg file start out as a text file containing something similar to the following:
1. Set the GUI/Web config password to 1234; the password must NOT be 0
2. (disabled) if configuring via the phone’s web interface is desired.
Unfortunately, the actual .cfg file is made by using a Cisco software tool to compile the text file into the desired .cfg file – and this tool is only available to users with support contracts. If you do obtain the official software kit then there is a sample .cfg containing the required text that can just be copied to your TFTP root folder.
If you do not have the ability to re-setup your UIPassword, you may want to carefully consider whether resetting your phone completely is a good idea!
Footnote: All of this hassle seems to be Cisco’s way of “punishing” those who dare to use SIP on these phones!
Rebooting the phoneThe phone can be reset through the keypad by scrolling into Settings, then pressing **#** and answering “yes” to the prompt “do you wish to reboot the phone?”
