Avaya SA PREF AES R10 GR HA SM (A5)

Keep mission-critical Avaya Application Enablement Services (AES) R10 instances operational and recoverable during planned upgrades and unplanned incidents with 36 months of A5-tier maintenance (MPN 352086). This service preserves HA configurations and delivers software fixes, security updates and access to Avaya technical resources so infrastructure teams can minimize downtime and preserve integrations with contact-center middleware. The agreement is tailored for deployments that require vendor escalation and a higher-touch maintenance posture, justifying the investment compared with basic entitlements. Use this package when AES R10 underpins telephony APIs, CTI integrations and high-availability clusters — it ensures predictable lifecycle support, faster resolution paths, and continued compatibility with Avaya releases. Pricing reflects the reduced operational risk, direct vendor access, and continuity assurance you need for $5K–$500K infrastructure decisions.
