## Summary

Dacorum Borough Council bought 100 enhanced Session Initiation Protocol (SIP) channels and rental of direct dial-in (DDI) telephone numbers for its communications services. SIP channels carry voice calls over an internet connection; DDI numbers allow callers to reach individual extensions directly. The requirement is for a three-year supply and rental arrangement, rather than installation works or a general telecommunications service. The buyer is Dacorum Borough Council, based in Hemel Hempstead, and delivery is in the Dacorum area of Hertfordshire. The procurement falls within digital transmission equipment and communications infrastructure, specifically enhanced SIP capacity and telephone numbering.

The procurement is complete and the contract has been awarded to 4SIGHT COMMUNICATIONS LIMITED. Dacorum Borough Council used a direct award below the applicable threshold, without competition. The award covers one lot: 100 enhanced SIP channels and rental of DDI numbers. The contract was signed on 30 September 2026 and runs from 1 October 2026 to 30 September 2029. Its value is £51,695.80 excluding VAT, or £62,034.96 including VAT. The published procurement information does not state a separate award date or explain any evaluation criteria; the route was a non-competitive direct award rather than a scored competition.

This award shows demand from Dacorum Borough Council for a defined telephony package: 100 enhanced SIP channels together with DDI number rental, supplied as an ongoing service rather than a one-off equipment purchase. A credible competitor for a similar requirement would need to provide SIP capacity at this scale, arrange and maintain DDI numbers, and support reliable business voice communications across the council’s operations. The selected supplier is an SME, indicating that this requirement was deliverable by a smaller specialist rather than requiring a large national contractor. The council used a direct award without competition, so the award does not demonstrate which technical, service or price factors would prevail in a future competitive exercise. Relevant telecommunications providers should be able to evidence the capacity and service continuity needed for this specific combination of channel supply and number rental.
