Avaya CMS R18 HA/Surv Dual Role Upgrade License

Keep contact center operations available when infrastructure conditions change with an Avaya CMS R18 dual-role upgrade license for high availability and survivability. This entitlement is designed for existing CMS environments that need stronger continuity planning without introducing a new platform or reworking the entire communications stack. For organizations where uptime directly affects customer experience, the value is in preserving service paths and supporting recovery-oriented architecture. The dual-role structure is intended for deployments that must remain operational through planned maintenance, localized failures, or site-level disruption, giving infrastructure teams a cleaner way to align licensing with resilience goals. Because it is a software license, it integrates into procurement and lifecycle management without adding hardware complexity. That makes it a practical fit for enterprise contact centers that already run Avaya CMS R18 and need to formalize HA and survivability capabilities as part of a broader continuity strategy.
