Introduction to cucm_im_p_11.5_vmv8_v1.2.ova Software
This SHA-512 signed OVA template (12.8GB) enables rapid deployment of Cisco Unified Communications Manager IM and Presence (IM&P) 11.5 services on VMware vSphere 8 environments. Released through Cisco’s Collaboration Solutions portal in Q1 2025, it resolves critical TLS 1.2 cipher suite vulnerabilities while maintaining PCI-DSS 4.0 compliance for enterprise messaging systems.
The package pre-configures Jabber XMPP services with optimized resource allocation for UCS C220 M5 servers, supporting up to 50,000 concurrent chat sessions per cluster node. It integrates with Cisco Unity Connection 15.0+ for unified voicemail solutions and supports hybrid deployments with Webex Messaging v4.2.
