Voice Tenders
See open voice tenders and awarded contracts for the UK public sector.
Voice here means the technology layer: VoIP and IP telephony, interactive voice response (IVR), voice gateways, and PSTN-to-digital-voice migration off ageing ISDN lines. It sits next to the wider call centre category, which covers contact centre staffing and operations, not the voice technology underneath.
There are 708 matching notices on record, 333 already awarded and 58 at pre-tender stage. Councils, NHS trusts and police forces run most of it, replacing legacy phone systems with cloud voice platforms.

Frequently asked questions
Frequently asked questions about interactive voice response, voice over ip, voice over internet protocol, voip, voice gateway, digital voice in the UK public sector.
How do I get voice technology contracts in the UK public sector?
Search live VoIP, IVR and telephony tenders on public and private portals, or move earlier. On Stotles, you can read a buyer's IT or digital strategy for signs of a phone-system or contact-centre technology refresh before the tender opens, see what is open now, and build your bid from there. For more, explore the platform.
How is this different from call centre tenders?
This page covers the voice technology itself: VoIP and IP telephony, IVR platforms, voice gateways and PSTN-to-digital migration. Call centre tenders cover the wider contact centre category, including staffing, outsourced call handling and customer service operations that may run on top of this technology.
What CPV codes cover voice and VoIP tenders?
The corpus most often carries 64215000 (IP telephone services) and 64227000 (Integrated telecommunications services), with 72212512 (Interactive voice response software development services) appearing on IVR-specific builds.
Why do ISDN and PSTN replacement projects show up here?
UK telecoms providers are switching off the old PSTN and ISDN networks, so buyers are re-tendering their phone systems for VoIP and other digital voice technology as part of the switchover. Those migration contracts are voice technology procurement even where the notice does not use the word "voice".
