This project falls under the telecommunications and IT services industry category, with a focus on modernising the existing voice systems. The primary aim is to design, build, migrate, and operate a hybrid solution combining on-premises calling capabilities with cloud-native call management. The procurement process is currently at the planning stage, with significant dates including a future notice date of 21st May 2027 and an anticipated contract start date of 12th October 2027, running potentially until 12th December 2034. This procurement, valued at approximately £55 million (net), is being executed through a competitive flexible procedure, and it spans multiple locations including the UK and overseas territories such as Gibraltar, Cyprus, and Brunei. Classification under the special regime of defence and security indicates its strategic importance.
