How it works
Provisioning capacity, delivered straight to your agents
We provide pre-approved UK number capacity and fixed-cost voice connectivity directly into supported AI Voice Agent platforms, so you can deploy numbers for your customers without operating your own telephony infrastructure.
Capacity, not a bundle of numbers
Each account is approved for a defined number provisioning capacity, for example 100, 200, 500 or 1,000 numbers. You are buying the right to operate a number estate of up to that size, not a fixed list of numbers chosen on day one.
That means you never hold numbers you do not need, and you can pick the right number for each customer at the moment you onboard them.
Two ways to provision
Allocate up front
Provision numbers immediately when you already know your deployment requirements.
Draw down just in time
Select and provision numbers as your own customers are onboarded. Ideal when area codes matter, when different clients need different number types, or when you don't yet know where future customers will be based.
Example: onboarding a customer in Manchester
Where supported by the available number ranges, draw-down lets you give each customer a local number as they sign up.
You win a customer
Your AI Voice service signs a new customer based in Manchester.
Choose a local number
Request or select an appropriate Manchester number.
Provision from capacity
The number is provisioned from your existing account capacity.
Attach to the agent
The number is connected directly to your customer's AI Agent.
Go live
The agent starts answering calls on its new local number.
Direct-to-agent delivery
Numbers are delivered directly into supported AI Agent environments. You don't need to build or operate any telephony infrastructure of your own: you build the agent, we connect it to the UK telephone network.
What you no longer need to run
SIP infrastructure
A PBX
Session border controllers (SBCs)
Carrier interconnects
Telephony routing infrastructure
What you get to focus on
Agent design and prompts
Workflows and integrations
Application logic
Onboarding your customers
Growing your AI Voice service
Direct delivery also means fewer systems to maintain, faster customer deployment and a single supplier relationship for UK numbering and voice delivery, which makes scaling easier.
Shared concurrent channels
The number of telephone numbers you hold doesn't tell you how many calls you'll handle at once. A customer with 100 numbers can generate more simultaneous calls than another with 1,000.
So channels are treated separately from numbers. Every 100 numbers of provisioning capacity includes 50 concurrent channels, pooled across your whole account so capacity follows your real traffic. If you need more, additional channel packs are available for a fixed monthly charge.
| Provisioning capacity | Included shared channels |
|---|---|
| 100 numbers | 50 channels |
| 200 numbers | 100 channels |
| 300 numbers | 150 channels |
| 500 numbers | 250 channels |
| 1,000 numbers | 500 channels |
