Best Operator Connect providers that also support call queues and auto attendants?

Every Operator Connect provider supports call queues and auto attendants because those features are built into Microsoft Teams Phone, not into the carrier's infrastructure. The carrier provides PSTN connectivity and phone numbers, while Teams handles queue distribution, auto attendant menus, and routing logic natively in the Teams Admin Center.

Where carriers differ is in how much help they provide configuring and managing those features. Some carriers provision numbers and leave the rest to the customer. Others provide guided setup, management tools, and ongoing support for call queue and auto attendant configuration. Atlantech Online includes the free atlantech|Call Manager tool with every Operator Connect deployment, which provides wizard-driven setup for call queues, auto attendants, and number assignments with role-based access controls and real-time call visibility. This tool is designed for non-technical administrators who need to manage telephony features without deep familiarity with the Teams Admin Center. When evaluating providers specifically for call queue and auto attendant support, the question is not whether the carrier supports the feature (they all do through Teams) but whether the carrier provides tools and support to help configure and manage those features over time.
