Avaya SA PREF C/D AES R10 ADV TSAPI LG 3YMO

Preserve telephony integration availability and reduce risk for mission-critical contact center services with Avaya Preferred Advanced support for AES Release 10 TSAPI (MPN 352019J). This 36-month agreement targets environments that depend on CTI and application-level telephony features — providing vendor-backed troubleshooting, prioritized case handling, and release-specific guidance for AES R10 and TSAPI interfaces. By keeping vendor expertise on call for protocol-level issues and interoperability faults, you limit downtime on integrations that connect CRM, workforce management, and custom call-handling logic. Choose this plan when internal staff require direct Avaya escalation for TSAPI behavior, certified bug fixes, and a predictable support budget. The SKU matches enterprise procurement needs: term-limited coverage, documented service boundaries, and a clear upgrade path to broader Avaya maintenance offerings.
