Support mobility where fixed desk phones fall short. Avaya D200 IP DECT Dual Cell NA MTC is designed for enterprise environments that need wireless voice access across offices, service areas, and operational floors. It gives users the freedom to move while staying connected to the call flow that matters. This type of deployment is especially useful in environments where staff are not tied to a single workstation. Reception teams, warehouse coordinators, clinical support staff, and office personnel can maintain voice availability while moving through their day. For IT, DECT-based telephony can reduce dependence on Wi-Fi voice coverage and keep the user experience focused on reliable calling. The dual-cell design is a strong fit for organizations that need broader wireless coverage than a single-cell setup can provide. It supports a more deliberate telephony architecture for sites where call continuity, coverage planning, and operational flexibility all matter. For buyers comparing options, this model stands out when the requirement is controlled wireless voice access rather than a basic cordless handset.
