I have a Cisco 2911 router with the UC license running IOS c2900-universalk9-mz.SPA.157-3.M.bin and a SM-ES2-24-P switch installed into it with 5 IP phones connected to the switch. Please note that this is a Service Module switch and not an external switch.
I have everything working correctly including several background images to select from on the phones.
I can TFTP a file to the root directory with no problems and the the images are still available on the phones.
But as soon as I TFTP any file to a sub-directory on the router, the phones can no longer get the background images to select from.
To get the the background image selections to return on the phones by restarting the router.
The results below are after I TFTP'd a file to the PhoneFile directory on the router. | Background images NOT working
