[cisco-voip] COP files signed with k3 - you might need another COP file first...

[Lelio Fulgenzi]

Looks like that beginning with CUCM v10, COP files are signed differently. And you depending on your version, you might need another COP file first to recognize these new files named "k3". 

Not a big deal, but it was new to me.

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.
