We have lab setup of CUCM 8.6.2 with upgraded firmware of 9.3.1SR2 as device default for ex: 7941 phones. Later we did a service upgrade to CUCM 8.6.2SU3 and the default firmware changed to 9.3.1SR1. After the switchover, the phone registered back successfully but with existing SR2 not with default load of SR1.
my point is, When a phone boots up, it will check its nvram firmware with default load, If a phone's preloaded firmware is higher than device default, then it won't manually downgrade to default load. Am I right here?
if not, please let me know why it is not automatically downgrading to default load?
