Avaya SSU AES R4.X BSC TSAPI 501-1000 AN

Keep Avaya AES R4.x TSAPI environments under active support coverage with this SSU entitlement for 501-1,000 users. Designed for organizations that depend on telephony application integration, it helps preserve access to vendor-backed support resources and the continuity required for production call-control workflows. For infrastructure teams, support coverage matters as much as the platform itself. This entitlement is intended for environments where application event services and TSAPI connectivity are part of daily operations, and where downtime or delayed assistance can affect contact center performance, workflow automation, and user productivity. It provides a clear path to maintain support status for the specified user band without overbuying coverage you do not need. Choose this option when you need to keep an existing Avaya AES deployment aligned with support requirements and operational expectations. It is a practical fit for enterprises that value predictable maintenance planning, vendor accountability, and a cleaner procurement path for renewing critical software support.
