Introduction to UCCX_8.5.1.part05.rar Software

Cisco Unified Contact Center Express (UCCX) 8.5(1) represents a critical maintenance release for mid-market contact center solutions, with the UCCX_8.5.1.part05.rar file serving as the fifth segment of the multi-part installation package. This archived component contains essential system binaries, localization files, and security certificates required for full deployment.

Compatible with Cisco Unified Computing System (UCS) C-Series servers and virtualized environments using VMware ESXi 6.0+, this version primarily addresses stability issues reported in earlier 8.5.x releases. While Cisco officially transitioned to Finesse as the exclusive agent desktop in later versions, this archive preserves backward compatibility with legacy CAD clients during phased migrations.
