Here is for the 7912:
. Download the SCCP Software Package Zip file.
2. Create the bitmap of the image to load to the phone
-The bitmap must be 88x27 pixels in size
-The bitmap must be black and white
-The bitmap must be saved as a monochrome image type
3. Convert the bitmap into a logo image using bmp2logo.exe
-bmp2logo x input_file output.logo
where x is an arbitrary number
-example: bmp2logo 10 cisco.bmp cisco.logo
4. Create a text file that will be used to build the ld or gk cfg file
-The file can be any name
-Must contain the upgradelogo key
-The SampleLogo.txt can be used as a template.
NOTE: the image number defined in step 3 must be used in this text file
5. Create the cfg file, use the cfgfmt.exe
-cfgfmt SampleLogo.txt lddefault.cfg
NOTE: if the same image is desired on all 7905's and 7912, use the lddefault.cfg and gkdefault.cfg files.
6. Move the .logo file into the TFTPPATH directory
7. Move the lddefault.cfg or gkdefault.cfg) (attached) into the COUNTRY specific folder.
-The ld or gk cfg files will need to be in at least \TFTPPATH\United_States
NOTE: The cfg file will need to be copied to each COUNTRY directory supported by the CM.
8. Reboot the 7905 or 7912 for the new image to display
I have some problem with the change of LCD logo. I have a Cisco IP Phone 7912G. I created a bmp file monochrome 88X27 pixels and with bmp2logo.exe covert to milogo.logo
bmp2logo 0 milogo.bmp milogo.logo
I modify gkdefault.txt file with the following line:
Then copy the files (cfg and logo) to TFTP server. Then when I reloaded the IP Phone only the Cisco Logo appears.
Can you know what's wrong?
This link is for the 7940/7960:
The first link that you say me returns the next: There are currently no files for this type and the link to the 7940 and 7960 I can't visit it because I can't see it with my single account. I can do nothing.
Try this link:
I can use that link without logging into cisco.
Vey good this link but I can't follow this instructions because I must to dwonload SDK from Developer Support Central and this download is for registered customers only.
