AVAYA SA PREF C/D CMS R20 HA SUPERVISOR 3YMO

Keep CMS R20 high-availability supervisor services operational with a 36-month Avaya maintenance entitlement. This offering covers the CMS R20 HA Supervisor component, providing official vendor support for the supported term so your infrastructure team can prioritize uptime and predictable lifecycle management. The SKU maps directly to Avaya's support catalog and is intended for organizations that require vendor-backed maintenance on supervisor elements of Avaya CMS R20 high-availability configurations. Choosing this entitlement reduces procurement ambiguity: it confirms compatibility with R20 supervisor licensing and maintains your access to Avaya support channels for the covered period. This is a technical maintenance renewal SKU, not new product license activation — purchase when extending or aligning existing CMS R20 HA Supervisor support terms. Ideal for enterprise contact centers where supervisor availability directly affects SLAs and operational stability.
