Your phone comes with firmware already installed, which is specific to the call control system that your
phone uses.
Occasionally, your administrator upgrades the phone firmware for you. This upgrade happens in the
background even if you are using your phone.
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.
