## Summary

The procurement process involves OFCOM, the UK communications regulator, which is seeking expert consultancy for the implementation of Calling Line Identity (CLI) authentication using the IETF STIR standard protocols. This contract, valued at £26,500, falls under the miscellaneous business and business-related services category and is located in London (postal code SE1 9HA). The procurement method used is an open procedure, with the contract period starting from 1st February 2021 and concluding on 31st March 2021. Although the tender period ended on 21st December 2020, the award was officially published on 26th February 2021.

This contract represents an excellent opportunity for businesses specialising in telecommunications consultancy and technology services, particularly those with experience in standards compliance and authentication processes. Small and medium-sized enterprises (SMEs) and voluntary, community, and social enterprises (VCSEs) will find themselves well-suited to compete due to the nature of the requirements. Engaging in this sector could position them advantageously for future tenders that focus on similar expertise in communications technologies.

## Notice

Ofcom has a requirement for expert review of the use of the IETF STIR standard protocols in the UK for the purposes of Calling Line Identity authentication. We require an expert review of the developments in North America including: - Details of what will be implemented by the specified dates with regards to technical capabilities and governance processes; - An assessment of the likely impact, taking into account the expected proportion of IP to non-IP lines at the specified dates; - How CLI authentication will be dealt with for non-IP networks; - How verification and authenticity will be communicated to the called party; - The expected trajectory of CLI authentication after July 2021.
