we have CUCM 7.1.3 and wanted to know if we can upgrade our IP Phone 7975G with new firmware SCCP75.9-3-1SR4-1S or do we need to have license for that ?

Hi ,
you do not require any license for upgrading the phone firmware.
Just refer the release notes for details
For all SCCP firmware upgrades from firmware release versions earlier than 8.3(3) to Version 9.3(1) or later, you must first upgrade your phone firmware to an intermediate version (8.3(3) to 8.5(2)) and then upgrade to 9.3(1).
after u upload the finrmware in Call maager server, restart the TFTP service.
