Phone Firmware and Upgrades

Your phone comes pre-installed with firmware that is specific to the call control system.

not using your phone because the phone resets to use the new firmware.

When new firmware is available, the Ready to upgrade window is displayed on your phone and a timer
begins a 15-second countdown. If you do nothing, the upgrade proceeds.
You can postpone your firmware upgrade for 1 hour and up to 11 times. The upgrade is also postponed if you
make or receive a phone call.
