Bring a dedicated desk-phone experience to Microsoft Teams calling with a business media phone designed for enterprise environments. The Poly CCX 505 helps organizations standardize voice access at the desk while keeping deployment simple through PoE support. This model is a strong fit for teams that want a purpose-built calling endpoint rather than relying only on softphone workflows. The compact design works well in offices, reception areas, and shared workstations where space is limited and consistency matters. PoE support also reduces installation friction by allowing power and network connectivity through a single cable in many deployments. For procurement teams, the TAA designation adds value in environments with public-sector or compliance-driven purchasing requirements. That makes this model especially relevant where sourcing rules matter as much as user experience. It is a practical choice for organizations that need a professional desk phone aligned to Microsoft Teams and a controlled buying process. Choose it when you want a polished endpoint that supports standardized rollout, cleaner desks, and a more consistent calling experience across the organization.
