Accenture | Professional Services | 791000 | $64.9B | Ireland | Microsoft | Microsoft Teams Phones | PBX, VoiP and Phone Systems | 2020 | n/a | In 2020, Accenture deployed Microsoft Teams Phones as part of a global rollout of Microsoft Teams to more than 500,000 employees, positioning the implementation within the PBX, VoiP and Phone Systems category. The deployment of Microsoft Teams Phones was executed at scale across Accenture’s global workforce, with Islands mode staging, a transition to Teams Only mode, and centralized operational oversight tied to enterprise collaboration and calling needs. The implementation included Teams Phone with Direct Routing and the installation of session border controllers in offices with local internet egress, while offices without egress were routed to datacenters hosting SBCs. Accenture migrated more than 3,000 Polycom meeting room and desktop phones and moved hundreds of call queues into Teams, and it provisioned Microsoft Teams Rooms and more than 700 Microsoft Surface Hubs to deliver a consistent meeting experience. The company also developed bots and more than 60 Teams-based apps to support HR, technical support, client account insights, and project workflows, extending the functional footprint of Microsoft Teams Phones into productivity and business process contexts. Operational telemetry and service quality were centralized, the IT team monitored call performance using the Call Quality Dashboard and extended analytics by building a custom Power BI dashboard to filter metrics by office, connection type, and internal call categories. Network and configuration work focused on internet bandwidth planning, quality of service, and firewall tuning, including adjustments to User Datagram Protocol flood settings to prevent Teams traffic from being blocked as call volumes rose. Microsoft Endpoint Manager was used to push Islands mode and subsequent configurations, and custom deployment tools orchestrated staged migrations and configuration variants for specific projects and compliance settings. Governance and change management were structured and iterative, Accenture used a phased rollout with waves of 2,000 to 5,000 users per region per day and larger weekend moves, migrating non enterprise voice users before enterprise voice users and migrating all enterprise voice users within an office together to simplify routing. The company enforced staged removal of the Skype for Business meeting plugin from Outlook, established a global Teams champion network for local support, and published detailed training guides to reduce user confusion between platforms and accelerate adoption. Deployment windows were often scheduled outside business hours to manage cutover risk and validate call quality before wider propagation. The implementation produced measurable adoption and usage signals that were tracked post rollout, within six months more than 100,000 users were active early in the rollout and 350,000 users were active within weeks of broader availability, and the full Teams Only migration covered roughly 500,000 employees in about two and a half months. Accenture reported improved internal IT satisfaction scores of four to five percent for Teams versus Skype for Business, a five percent reduction in poor Rate My Call scores, and a substantial increase in collaboration minutes during the COVID 19 period, with audio minutes rising from roughly 300 million to one billion per month and video minutes increasing from 20 million to over 90 million. | |

Governance and program management were led by the department’s IT Program Delivery coordinator, who established IT governance, risk and compliance processes for the rollout, measured and reported compliance, and coordinated staged deployment across sites. The project emphasized centralized configuration controls, structured user onboarding, and change management processes to align telephony operations with departmental compliance requirements. | |
