+==== Basic config ====
 The7905/7912 series phones from Cisco use a different style of config files when configuring from TFTP. One composes the configuration file and then converts it to a binary format the phone can read. This conversion is done using the cfgfmt utility which you can find in the .zip file of your firmware image.

 If your phone asks for a password, you might want to reset it to the factory defaults. The default password (for the 7912) is 1234.\\
-=== Audio parameters ===
+==== Audio parameters ====
 The default SIP software load results in an odd fault: no receive audio on many calls except if you dial a digit after the call connects. This is due to silence suppression being on by default. This can be changed in the web configuration under Audio Parameters; be sure that AudioMode is set to 0x00000010 rather than 0x00000011.\\
 Note that the bits of the Audio Parameters also set the DTMF method used, as follows:\\

+==== Upgrading the software ====
 Download the firmware package, copy the upgradecode line from the gkdefault.txt file in the package, paste it into your SIP config text file and run the cfgfmt program (cfgfmt.exe for Windows, cfgfmt.linux for Linux and dfgfmt.sun for Sun) to convert it to binary. Upload the firmware .sbin (or .zup with older 7905s) and the new gkdefault.cnf to your tftp server and reboot the phone.\\

 It is also possible to change the logo on these phones, but a different approach is needed than with the 7940/60 series.\\

 If 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.\\

 You may run into a problem where your 79XX phone loads the appropriate GK file or gkdefault.cfg from the TFTP server and just stops there, even though you expected it to download a new logo, firmware, etc. Make sure that your “Profile Encrypt Key” is set to “0”, and not any other value.
