Introduction to cucm_im_p_12.5_vmv13_v1.0.ova

This OVA template provides a preconfigured virtual machine for Cisco Unified Communications Manager IM&P (Instant Messaging & Presence) version 12.5(1)VMV13 deployments. Designed for VMware environments, it streamlines implementation of secure enterprise collaboration services while maintaining compliance with Cisco’s virtualization best practices.

Certified for use with Cisco Unified Communications Manager 12.5(1)SU3 and later, this template was officially released on December 4, 2020, as part of Cisco’s collaboration virtualization optimization initiative. The package reduces deployment time by 65% compared to manual configurations while ensuring standardized security baselines.
