Avaya SA PREF C/D AES R10 ADV TSAPI SML 1YMO

Sustain mission-critical TSAPI telephony integrations with one year of Avaya Preferred Software Assurance for AES R10. This support offering preserves runtime stability for Advanced TSAPI (SML) deployments by providing access to software updates, security fixes, and Avaya support channels tailored to AES R10. Small-scale environments get entitlement to prioritized case handling and software correction paths without re-architecting integrations. Use this contract to manage change windows, apply critical patches, and maintain API compatibility when upgrading endpoints or SIP/telephony components. Procurement teams will find a clear value proposition versus reactive break/fix purchases: planned assurance lowers operational risk, shortens mean time to repair, and preserves custom TSAPI behaviors that higher-volume support tiers may not address the same way. Specified for deployments that require focused TSAPI continuity rather than broad platform services, this one-year plan is ideal when managing controlled budgets while keeping core telephony integrations resilient.
