[cisco-voip] Cisco 7970 phone firmware upgrade path

[Matthew Loraditch]

For all SCCP firmware upgrades from firmware release versions earlier than 8.3(3) to version 8.5(3) 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(3) or later.

Subject: [cisco-voip] Cisco 7970 phone firmware upgrade path

Afternoon all,

I have a few Cisco 7971G-GE phones in my ver 11 cucm cluster, running firmware version 'SCCP70.8-0-4SR3AS'

When I am attempting to upgrade these devices to the default phone load on our cluster (SCCP70.9-4-2ES27S) the phones are not taking the new firmware.

Can anyone advise of an interim firmware I can upload to our cluster to use in the upgrade process?

Many thanks

James
