Tender description
Stockton and Darlington councils currently have a contract with Cisilion to provide a resilient SIP service to Xentrall Landing zone in Azure cloud of use by both. This SIP service carries all incoming and outgoing external calls for the councils and terminates on resilient Ribbon Session Border Controllers that route calls to Teams Voice in Azure or the on-premises Netcall CRM's used by both council's Customer services departments. These Ribbons servers are provided and supported by Cisilion in a separate contract. This contract also includes the provision of the current DDI extension number ranges e.g. 01642 52xxxx for Stockton. This DDI number provision also includes the Stockton "Gold Number" ranges which the council have had since the 80's. Cisilion were essential with the migration to Gamma SIP as part of the previous contract and we have been happy with that support and the help they have provided since then.

About the buyer
Stockton Borough Council is a local authority that advertises its tenders through the North East Procurement Organisation, or NEPO. Suppliers register free on NEPO's Open system, where the council advertises contracts and invites tenders. A contract register lists every contract the council has awarded or joined, including framework agreements. The register updates continuously as new contracts are agreed, rather than being published as a static list. Contracts above certain value thresholds require suppliers to register on the Central Digital Platform, introduced under new procurement legislation from February 2025.
UK local government drives £140bn in annual procurement, led by social protection (£66.6bn) and education (£57.1bn).
Over the past 5 years, most of Stockton Borough Council's contract awards have been in construction work, health and social work and software and information systems.
