8851 SIP Upgrade Problem

[Ekin Gumus]

Hello All,

I am trying to upgrade 8851 SIP phone but getting md5 value error. I've tried to upgrade to cmterm-88xx-sip.10-3-1-20.k3.cop.sgn and cmterm-88xx-sip.11-0-1-11.k3.cop.sgn both gave me error about md5. I have checked md5 values and they matched. Restarted tftp services on both cucm nodes and also check bug search tool but could not find anything reliable. 

CUCM Ver:

System version: 8.6.2.20000-2

thanks.

Hi Ekin,

You will need to install ciscocm.version3-keys.cop.sgn on all cucm servers and then try the upgrade as per the Read me files for 88XX series

Note: To improve software integrity protection, new public keys are used to sign cop files for Cisco Unified Communications Manager Release 10.0.1 and later. These cop files have "k3" in their name. To install a k3 cop file on a pre-10.0.1 Cisco Unified Communications Manager, consult the README for the ciscocm.version3-keys.cop.sgn to determine if this additional cop file must first be installed on your specific Cisco Unified Communications Manager version. If these keys are not present and are required, you will see the error "The selected file is not valid" when you try to install the software package.
