- Integration with Cisco Webex Calling cloud services
- Compliance with E.164 numbering standards for global deployments
Compatibility
- Virtualization Platform: VMware vSphere 8.0 (ESXi 8.0 Update 2+)
- Minimum Hardware: 16 vCPUs, 64GB RAM, 500GB storage (thin-provisioned)
- Supported UCS Models: C240 M6/M7 servers with VIC 1500 adapters
2. Key Features and Improvements
A. Enterprise Scalability
Version 11.0 introduces:
- Multi-cluster geographical redundancy with automatic failover
