Karthik,

Uploading phone firmware to CUCM will not result in phone reboot ( no impact on phones at all ). Whenever phone reboots next time, it will find new firmware in TFTP & upgrade the firmware.

Hi Gajanan,

One more question please.

When we are restarting the TFTP server in call manager end will phones will reset?

Sorry to ask again first time i was involving the task and to get double confirm.

Thanks and regards,

Karthik

No, restarting TFTP Service will not result in phone reboot.

Usually, TFTP service is restarted when the phones doesnt upgrade the firmware ( post phone reboot ) themselves even after the new firmware is installed on CUCM.

Hi,

Uploaded new firmware in TFTP server, tried to test few phones by resetting, it went to upgradation and shows error and loaded with old firmware.

Please assist.

Thanks

Karthik,

This is a typical case where phone needs intermediate upgrade before reaching to destination version. Do let us know your present & desired phone firmware version and we should be able to help you with intermediate firmware version to which you will need to upgrade the phone first.
