Avaya SA PREF CMS R18 TCS H-SES 3YAN

Protect Avaya CMS R18 with a 3-year preferred support entitlement built for TCS H-SES environments. This service is designed for organizations that depend on contact center availability, where even short interruptions can affect service levels, staffing efficiency, and customer experience. By extending coverage across the support term, this entitlement helps keep the platform under active vendor support while simplifying lifecycle planning for enterprise teams. It is a practical fit for operations that need predictable coverage, clear ownership, and a direct path to assistance when issues arise. For procurement and infrastructure leaders, the value is in continuity. Instead of managing unsupported software risk or piecing together ad hoc assistance, this entitlement keeps the CMS R18 environment aligned to a defined support window. That makes it easier to plan budgets, maintain operational confidence, and protect the systems that route and report on customer interactions. Choose this support option when the cost of downtime is higher than the cost of staying covered.
