1. Introduction to cucm_im_p_11.0_vmv8_v1.1.ova Software

The ​​cucm_im_p_11.0_vmv8_v1.1.ova​​ serves as Cisco’s preconfigured virtual machine template for deploying Unified Communications Manager (CUCM) 11.0 in VMware vSphere environments. Designed for enterprise VoIP infrastructure, this Open Virtualization Format Archive (OVA) package streamlines the implementation of call processing, session management, and collaboration services.

Cisco officially released this build to address growing demand for cloud-ready UC solutions, aligning with modern virtualization trends observed in Cisco UCS deployments. Compatible with VMware ESXi 6.0-6.7 hypervisors, it supports integration with Cisco Unity Connection, IM&P servers, and third-party SIP devices.
