New and Changed Information
There is no new or changed information for firmware release 8.5(4).
Installation Notes
This section contains these topics:
•Installing Firmware Release 8.5(4) for SCCP
•Installing Firmware Release 8.5(4) for SIP
•Installing Firmware for the Cisco Unified IP Phone Expansion Module
Installing Firmware Release 8.5(4) for SCCP
This section describes how to install firmware release 8.5(4) for SCCP, and includes these topics:
•Firmware Upgrade Issues for SCCP
•Firmware Installation Procedure for SCCP
Firmware Upgrade Issues for SCCP
Note For all SCCP firmware upgrades from firmware release versions earlier than 8.3(3) to version 8.5(4) or greater, you must first upgrade your firmware to version 8.5(2). Once you have upgraded to version 8.5(2), you can upgrade your IP Phone to version 8.5(4) or later.
Note This section applies to the Cisco Unified IP Phone 7971G-GE, 7970G, 7961G-GE, 7961G, 7941G-GE, 7941G, 7931G, 7911G, and 7906G.
The following upgrade issues apply:
•If you are currently running firmware earlier than 6.0(2) on a Cisco Unified IP Phone and want to upgrade to 8.x(x), you must first install an intervening 7.0(x) load to prevent upgrade failure. Cisco recommends using the most recent 7.0(3) load as the intervening load to avoid lengthy upgrade times.
•If you are currently running firmware 6.0(2) to 7.0(2) on a Cisco Unified IP Phone and want to upgrade to 8.x(x), you can do so directly. However, expect the upgrade to take twice as long as usual.
•Device packs are required to enable IP Phones in the Cisco Unified Communications Manager database. For Cisco Unified CallManager 4.2 and earlier, these device packs are required. For Cisco Unified CallManager 4.3 and Cisco Unified Communications Manager 6.0 and later, you must run the device pack and reboot the Cisco Unified Communications Manager server.
To access the device packs, follow these steps:
