## Summary

Orbit Group Limited bought a telecommunications service providing voice calling through Microsoft Teams Direct Routing using SIP. The service supports back-office staff across all of Orbit’s office locations in the United Kingdom. The requirement covers the delivery of business voice connectivity rather than general IT support or equipment supply. Orbit Group Limited is the buying organisation and the procurement was for services. The contract is centred on integrating voice calling with Microsoft Teams across a geographically distributed office estate, so relevant suppliers are those able to provide and manage SIP-based voice services alongside Teams connectivity for office-based users. The requirement was treated as a single service package covering the UK-wide office network.

The procurement is complete and the contract is active. Orbit used a below-threshold limited competition and obtained three quotes. BT Group PLC was awarded the contract for the single lot. The contract was signed on 31 July 2026, runs from 8 August 2026 to 7 August 2029, and includes a two-year break clause. Its value is £61,253.50 excluding VAT, or £73,504.20 including VAT. The evaluation basis is reflected in the limited-competition route rather than a published open tender procedure. This outcome confirms that Orbit selected BT for the Microsoft Teams Direct Routing SIP service across its United Kingdom office locations. The procurement was below the applicable threshold.

This award is relevant to telecommunications providers, managed communications businesses and systems integrators with practical capability in SIP voice services, Microsoft Teams Direct Routing and business telephony. A credible competitor would need to support voice calling for back-office users across multiple office locations, manage a UK-wide service footprint and integrate reliably with an organisation’s Microsoft Teams environment. Service management, resilience, fault handling and the ability to operate a business voice service at multi-site scale would be important commercial strengths. Orbit used a limited competition and sought three quotes, showing that comparable suppliers may need a clear route to the buyer and a concise, competitive service proposal. The requirement provides a specific benchmark for the type of Teams-integrated telecommunications service Orbit purchases.
