Update background image on Cisco Phones.

[Sergey Lubenkov]

Hi guys,

Is it possible to force Cisco Phones to re-download background image file from CUCM 11.5???

I need to update company logo, so I've made a new file with the same name as old one and replaced it in TFTP. However, phones don't want to re-downloaded it and keep using the old one even if I do phone reset from CUCM. If I am re-setting background manually from the phone preferences everything works.

Thank you

Try below link and suggestions, Hope that should fix your issue.

NOTE: When dealing with image difficulties, try restarting the TFTP after each file upload

Create new image is not a big deal, more interesting how to replace existing image with a new one on hundreds of phones.

"Common Phone Profile -> Background Image file name with no path, and uncheck Enable End User Access to Phone Background Image."
