Avaya SA PREF AES R10 BSC TSAPI ECD

Protect enterprise telephony integrations that rely on Avaya AES R10 and TSAPI with a defined 36-month support agreement (MPN 352461). This support package ensures entitlement to vendor-supplied software fixes, advisories relevant to TSAPI and BSC interfaces, and a formal escalation path into Avaya technical teams. For architects who depend on TSAPI for CTI integrations, the agreement reduces the exposure to interface regressions, provides predictable maintenance planning, and preserves compatibility assurance across supported patch releases. The arrangement also simplifies procurement: instead of one-off emergency purchases or unmanaged patching, teams gain continuous coverage and documented support terms for a three-year window. Use this when maintaining high-availability CTI functions and when third-party application vendors require vendor-backed support for interface issues.
