Avaya SA ESS AES R6 ADV TSAPI LG 3YAN

Keep your Avaya communications environment under active support with a 3-year entitlement for AES R6 advanced TSAPI coverage. This product is aimed at organizations that depend on telephony integration, call control, and application connectivity across business-critical workflows. Rather than forcing a platform change, it extends the support relationship around the deployed environment so operations can continue with fewer interruptions. For infrastructure and procurement teams, the longer term matters. A 3-year coverage window reduces renewal churn and gives more room to align support planning with broader infrastructure strategy. That is especially useful when the environment still performs well and the business value comes from stability, not replacement. Advanced TSAPI support helps keep application-to-telephony interactions under vendor-backed coverage, which is important in contact center, workflow automation, and communications integration scenarios. This entitlement is a practical fit for enterprises that need predictable support for established Avaya assets. It helps protect continuity, maintain service confidence, and avoid gaps that can affect dependent applications. When the installed base is still doing real work, long-term support coverage is often the most efficient way to preserve value.
