The transition to newer hardware and virtualized environments (ESXi) created a "catch-22" for older UCOS versions. Many original 8.6(2) installers lacked the necessary drivers or scripts to recognize newer virtual hardware or to bypass specific certificate expiration issues that occurred after the software was originally released. The version of this ISO generally includes: Ensures the ISO is correctly seen as a

Version 8.6(2) is significantly past its End-of-Software-Maintenance (EoSM) date. While the patched ISO makes installation possible on newer hardware, it does not address the modern security vulnerabilities present in such an old kernel. This version should ideally be used only for lab environments or as a stepping stone in a multi-stage upgrade path to a supported version like CUCM 12.5 or 14/15.

Prevents the "Installation Failed" errors caused by expired security tokens within the ISO itself.
