What is the most common cause of misrouted calls when configuring queue-based routing, and how do platforms mitigate it?
Misrouting often comes from mismatched routing criteria in the data model, such as queue keys or routing-policy references that do not align with agent skills or customer attributes. Amazon Connect mitigates this by centering routing on a customer attribute schema used by contact flows, while RingCentral Contact Center mitigates it through queue, agent, routing, and interaction configuration tied to RingCentral identity-based access control.
