This guide covers the essential technical aspects, requirements, and best practices for virtualizing CUCM 15.
It was a typical Monday morning for the IT team at XYZ Corporation. The phone system, which was critical to their daily operations, was due for an upgrade. The current system, running on physical hardware, was nearing end-of-life and needed to be replaced. The team had decided to migrate to Cisco Unified Communications Manager (CUCM) 15, the latest version of the popular IP telephony platform.
Cisco Unified Communications Manager (CUCM) 15 represents a significant shift in Cisco's collaboration portfolio, moving to a modern 64-bit architecture. Virtualization is no longer just an option but the mandatory foundation for this release, requiring careful planning regarding hypervisor support, resource allocation, and upgrade paths.
