Avaya SA PREF CMS R21 Client Extension 3YAN

Keep your contact center environment aligned with how your teams actually work. SA PREF CMS R21 NEW/ADD CLNT EXT 3YAN extends client access for Avaya CMS R21, helping organizations scale user availability for operations, supervision, and reporting without reworking the underlying platform. This license is suited to enterprises that need additional client reach for day-to-day contact center management. Whether the goal is to support more supervisors, analysts, or operational users, the extension helps maintain access continuity across the CMS environment while preserving a structured licensing model. The 3-year term is a practical fit for organizations that plan capacity in multi-year cycles and want predictable coverage for their contact center tooling. It is especially useful when access requirements grow faster than the core platform footprint and the business needs a controlled way to add users. Choose this extension when CMS R21 is already in place and the priority is expanding client access with minimal disruption to established workflows.
