Avaya SA PREF AES R10 HA (A12) Support

Sustain AES R10 availability for contact-center integrations and telephony middleware with a three-year high-availability maintenance contract (MPN 352139). This subscription focuses on continuity: it provides maintenance entitlements and software updates scoped to Avaya Application Enablement Services Release 10, targeting environments configured for High Availability. The offering reduces operational risk by preserving supportability during OS or platform changes, enabling timely application of security and stability updates, and ensuring entitlement for vendor fixes. Procurement value comes from a single, predictable term that aligns vendor responsibilities with your AES R10 HA topology. This SKU is appropriate when AES R10 supports session management, CTI integrations, or PSTN/UC gateways that must remain available. Implementation and escalations follow Avaya support processes; customers should reference existing deployment topology and HA pair details when opening cases to minimize triage time.
