## Summary

The York and North Yorkshire Combined Authority, acting as the Fire and Rescue Authority, has completed a procurement process themed "Services for replacing ISDN lines with a SIP solution". This procurement, awarded under the industry category "Software package and information systems", was conducted through a direct procurement method via a single tender action (below threshold) to ensure continuity and compatibility with existing systems. The contract, valued at £36,168.54, was aimed at upgrading the communications infrastructure to support mission-critical platforms such as the 999 call handling system. The tender process concluded with the award given on 19th February 2026, and the contract is set to run from 10th March 2026 to 9th March 2027 in Northallerton, England, specifically at the North Yorkshire Police HQ, Alverton Court. The procurement has transitioned to the award stage, with NEC Software Solutions UK Limited as the sole supplier.

This tender offers significant opportunities for businesses specialising in telecommunications and information systems, particularly those able to provide SIP-based communication solutions. While this specific tender was directed at NEC Software Solutions UK Limited due to system compatibility requirements, similar procurement opportunities could benefit companies that are large-scale and capable of delivering resilient and secure communications systems tailored to emergency services. Organisations with a focus on mission-critical systems for public safety or those looking to expand into SIP solutions would find this sector ripe for growth as public entities look for technological upgrades, ensuring compliance and enhanced service delivery.

## Notice

NEC is delivering SIP-based communications including voice gateway, enterprise-grade switching platform and resilient support components. The new SIP infrastructure will replace the legacy NEC ISDN components with the SIP infrastructure. The SIP hardware underpins the Integrated Communications Control System (ICCS), mission-critical platform used by NYFRS. This NEC setup is tailored to support 999 call handling, ensuring resilience, security, and compliance STA has been recommended based on the justification that this is the sole supplier due to continuity and compatibility with the existing system.
