Avaya SA ESS C3000 R3 FMP ADDL LINES 1YPP

Protect call capacity and operational continuity by adding one-year support for additional lines on Avaya C3000 R3 (MPN 288371). This entitlement extends the software-assurance relationship for extra user or device lines, preserving access to vendor fixes, firmware updates, and remedial actions tied to those line licenses. For infrastructure teams managing phased rollouts or seasonal growth, this SKU avoids gaps between provisioning and full-term renewals. Choosing manufacturer-supported coverage for added lines reduces escalation friction when troubleshooting interoperability, avoids unsupported configuration drift, and keeps licensing aligned to active load. Compared with unmanaged or third-party workarounds, this renewal delivers predictable costs and vendor acceptance of root-cause diagnosis on the covered lines. Procure this add-on to match capacity increases without reissuing base licences or risking unsupported line behavior — a practical decision when uptime, traceability, and vendor accountability matter to enterprise telephony operations.
