Avaya UPG ADV AES R6 BSC TSAPI HA 3YPP

Keep telephony applications connected to Avaya infrastructure with Advanced AES R6, TSAPI support, and high-availability coverage. This package is built for organizations that depend on event-driven call control, third-party application integration, and service continuity across critical communications workflows. By extending support for three years, it helps reduce operational risk while preserving the integration layer that contact center, reporting, and workflow systems rely on. High-availability coverage is especially valuable where downtime can interrupt agent productivity, call routing visibility, or downstream business processes tied to telephony events. For enterprises standardizing on Avaya communications, this package supports a more controlled lifecycle for AES-based deployments. It is a practical choice when the goal is to keep existing integrations stable rather than replatform under pressure. The result is predictable support coverage for a core communications dependency that often sits between voice infrastructure and business applications.
