In early 2021, the UK Health Security Agency (UKHSA) required a large-scale Single Service Centre (SSC) to manage citizen communications related to pandemic and health incident management. The call centre needed to handle 2.7 million calls per month, with a maximum of 3,750 remote agents working from home. Cloud Fundamental, in partnership with MMS and HGS, was awarded the contract to design, build, and deliver this mission-critical service.
Key Challenges and Requirements:
- Handling a potential 2.7 million calls monthly with 3,750 agents.
- Quick scalability to accommodate a high but unpredictable volume of calls.
- Supporting agents working from home with bring your own device (BYOD) setups.
- Detailed management information reporting and billing breakdowns for calls.
Solution:
Cloud Fundamental developed a highly scalable solution using Amazon Connect as the core telephony platform, ensuring secure agent access via SAML federation through Microsoft Azure. The solution used AWS Lambda and DynamoDB to dynamically route calls and provide real-time queue and utilisation data. A custom Call Manager interface was developed for agents to manage calls efficiently, while real-time analytics and reporting were powered by Amazon Glue, EventBridge, and Athena.
Results:
The system went live in September 2021, handling 700,000 call minutes per month without any outages, with an average of 360 agents logged on concurrently. The infrastructure supports dynamic scaling to meet unpredictable call volumes. The detailed reporting solutions provide UKHSA with comprehensive call data, which is vital for resource planning and operational decisions. Additional services, including new queues and options, are already planned for implementation.
