Avaya SA ESS C/D Core R6 to Mainstream 3-Year Support

Extend vendor support coverage for Avaya core communications infrastructure with a 3-year mainstream service entitlement. Built for organizations that depend on stable service lifecycles, this offering helps keep essential systems within supported status while reducing uncertainty around maintenance planning and escalation paths. For infrastructure teams, the value is straightforward: preserve access to Avaya-backed support for a defined period, maintain continuity across production environments, and avoid the operational risk that comes with unsupported software. This type of coverage is especially important when communications platforms sit at the center of contact center, voice, or enterprise collaboration workflows. The 3-year term also supports procurement planning. Instead of managing short renewal cycles, teams can align support coverage with budget windows, refresh schedules, and internal change control timelines. That makes it easier to protect service availability while keeping lifecycle decisions deliberate and controlled. If your environment depends on Avaya core systems, this support entitlement helps keep those platforms covered, accountable, and easier to manage over time.
