Build a cleaner desk deployment with an IP phone intended for organizations standardizing on PoE infrastructure. The Avaya J179 700513569 is a no-power-supply model, which makes it a natural fit for network teams that prefer to power endpoints through the switch rather than manage separate adapters at every workstation. That matters in real deployments. Fewer power bricks mean less clutter, fewer failure points, and simpler rollout planning across reception areas, shared desks, and office floors. For procurement teams, the no-power-supply configuration can also align better with existing PoE standards, helping avoid paying for hardware you do not need. The J179 is a strong choice when the goal is dependable business telephony without unnecessary extras. It suits organizations that value consistency, serviceability, and a familiar desk-phone footprint. If your environment already supports PoE, this model keeps the endpoint focused on the job: clear voice communications, efficient installation, and a lower-friction path to large-scale deployment.
