Hi
I am planning to update the firmware across all our IP phones (7921,7941 & 7961).
A number of my users have added numbers to the phone book of the device, if I apply the firmware update will this wipe the phone book clean?
Regards
Paul

Hi Paul,
Firmware update should not affect address book entries of the phone but it's better to check Cisco release notes for any bugs associated with planned firmware version just like below URL.
