Avaya SA PREF+UA PRT 8X5 SYS C170 5YPP 355457

Protect Avaya System C170 deployments across the long term with a five-year preferred support package (MPN 355457) that targets availability within business hours. The plan pairs preferred technical assistance with coordinated parts replacement and vendor case escalation to reduce Mean Time To Repair and administrative burden on internal teams. Designed for organizations that require predictable, long-duration service coverage during core business periods, this SKU delivers a consistent support experience across years — simplifying budgeting and vendor accountability. Compared with short-term offerings, a 5-year commitment reduces contract churn, preserves negotiated service terms, and often lowers total cost of ownership by avoiding repeated procurement cycles. Use this plan for campus telephony, contact center edge systems, or distributed branch installations where 8x5 support hours align with operational needs.
