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. This tender presents substantial opportunities for businesses, especially those specialising in telecommunications infrastructure and IT services, to secure long-term contracts. Companies adept in designing, building, and managing hybrid communication solutions would particularly benefit. Furthermore, the procurement emphasises the support and modernisation of legacy systems, potentially appealing to businesses that offer SIP-enabled solutions. Small and medium enterprises (SMEs) are also encouraged to participate, highlighting inclusivity within the competitive landscape. The expansive project scope and duration promise robust avenues for sustained business growth and the development of new capabilities in advanced telecommunications and IT services. ## Notice The Authority Enterprise OFFICIAL voice system is ageing and requires modernisation.
