    No, it’s not necessary to have both services from Gamma to enable Direct Routing for Teams. However, Gamma’s Converged Access is specifically designed to connect business customers to our network in order to carry voice and video calls at a high quality. We also provide Quality of Service, our ‘end-to-end’ approach to designing, testing and providing services across both UCaaS and Access gives us the necessary visibility and control needed to deliver a consistent and robust voice and video quality to our business customers.
