The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Cisco Expressway (Expressway) software supports flexible deployment options and is available as a virtualized application for various Hypervisors. This lets enterprises run Expressway on a choice of Virtual Machine (VM) hardware platforms for ease of management and deployment in an existing data center. With a suitably specified VM platform, Expressway running on a Hypervisor performs identically to Expressway running on its appliance hardware.

New Hypervisor Support for On-premises Calling Solutions
Cisco Expressway X15.4 release introduces support for additional virtualization options. In addition to VMware vSphere ESXi, X15.4 supports Cisco NFVIS-for-UC and Cisco Compute Hyperconverged with Nutanix (CCHN) for on-premises calling deployments. These additions allow on-premises customers to choose between traditional VMware support, a Cisco-native virtualization layer for appliances, or a robust hyperconverged infrastructure (HCI) solution.
If you use PAK-based licensing, option keys for licenses can be obtained after the Expressway VM is installed, using the Expressway VM serial number (available from the Option key page and in the footer of the Expressway web interface).
