What is the benefit of deploying IP Office Server Edition over IP500 V2?

The primary benefit of IP Office Server Edition over the IP500 V2 is higher scalability (Option A). Server Edition supports up to 2500 users across multiple servers (Primary, Secondary, and Expansion Systems), whereas the IP500 V2 is limited to 384 users. This makes Server Edition ideal for larger or distributed organizations. Option B (lower cost) is incorrect as Server Edition typically involves higher costs due to its advanced features and hardware requirements. Option C (simpler installation) is false, as Server Edition’s multi-server setup is more complex than the standaloneIP500 V2. Option D (support for analog phones) applies to both systems, not a distinguishing benefit.References: Avaya IP Office Server Edition Deployment Guide, IP500 V2 Capacity Guidelines.
