Phone Firmware and Upgrades

The Wallmount Kit for Cisco IP Phone 8800 Series and Wallmount Kit for Cisco IP Phone 8800 Series with

single KEM meet the 307.2 Protrusion Limits section of the Americans with Disabilities Act (ADA) ADAAG

requirement for mounting a phone on the wall.

The Wallmount Kit for Cisco IP Phone 8800 Video Series is slightly larger and does not meet the 307.2

Protrusion Limits section of the Americans with Disabilities Act (ADA) ADAAG requirement for mounting

a phone on the wall.

Phone Firmware and Upgrades

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

Occasionally, your administrator upgrades the phone firmware for you. This upgrade happens when you are

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

Postpone a Phone Upgrade

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.

Procedure

Select Delay to postpone a phone upgrade.
