Ask anything about your campaigns, agents, and calls
create an agent for the Northwind campaign using this URL: https://www.northwindfinance.com/en/ — the agent in UK English
Got it — we'll set this up cleanly.
First step: which campaign should this agent belong to?
If this is a new one, I suggest a compliant name like: "Northwind UK Sales" (max 3 words, clean, no symbols)
Do you want me to:
- Use an existing campaign (tell me which one), or
- Create a new one with that name?
ok
Great — I'll prepare the campaign creation.
Here's what I'm about to create:
- Name: Northwind UK Sales
- Type: LEAD_GEN (default — we can adjust if this is more of a full sales or digital journey flow)
- Timezone: Europe/London (default)
- Start date: 2026-08-25
Before I proceed, quick check:
✅ Do you confirm creating this campaign with these details?
Also — is this agent meant to qualify leads or actually sell/convert users? That second part matters because it defines how I build the agent (Lead Qualification vs Autonomous Sales).
yes i confirm
✅ Campaign Northwind UK Sales created.
Now reading https://www.northwindfinance.com/en/ to build the agent: extracting products, tone of voice, and FAQs. I'll draft the agent prompt in UK English and show it to you for review before going live.

Testimonial
"For complex journeys in Telco, Utilities, and Insurance, VoiceB's autonomous agents guide users end-to-end — completing forms through live conversation, increasing digital sales, and reducing operational costs. It's the backbone of how we deliver smarter, faster, and more profitable inbound sales."
Victor M. Sanchez
Managing Director at GAIN, a t2ó ONE company
Case Study
"Our objective with VoiceB is clear: no customer should wait in a queue, and our agents should only speak with people who are reachable and genuinely ready to buy. VoiceB's autonomous agents attend every inbound call instantly, qualify the demand in seconds, and transfer only sales-ready customers to our team. For ready to buy customers, they close the sale fully autonomously, without needing a human agent at all. The result is a better experience for the customer and a much more efficient use of our sales capacity."
Oriol Pou
Head of Direct Sales at Holaluz
Case Study
"VoiceB delivered real, measurable results — increasing our sales by 153%, leads by 251%, and reducing CPA by 37%. Their team combined a decade of lead conversion know-how with a powerful autonomous agent platform. We now answer and qualify every inbound lead within 4 seconds. Game-changer."
Jordi Alonso

All of it inside a single conversation, without a human handoff.

Qualify and structure inbound demand, with every conversation resolved into clean, typed data.
→ Demand resolved into data

L2 — Decide
Route, prioritise and determine the next-best action against your own commercial rules.

→ Work done inside your stack
04
L4 — Close
Run the complete transaction autonomously, end to end.
→ Revenue without agents

Beyond AI voice
The conversation is the easy part. What happens during and after it is where revenue is won or lost.

The platform behind the agents
Voice quality is a commodity.
Proof is not.
The hard problem is knowing — deterministically and auditably — what every call was worth, and feeding that signal back into the systems that generate your demand.
The Outcome Engine — refined on hundreds of thousands of labeled production calls across telecom, energy, insurance and logistics.
Close the Loop With Your Ad Platforms
Every call becomes an auditable outcome — and every confirmed sale becomes a conversion signal. VoiceB sends Outcome Engine data back to Meta (Conversions API), Google Ads (offline conversion uploads), LinkedIn, TikTok and Microsoft Ads, so your campaigns optimize toward closed revenue instead of form fills.
Result: −37% cost per acquisition over 12 months at Primagas.
VoiceB never touches your budgets or keywords — it supplies the sale-level signal your campaigns are missing.

Frequently Asked Questions
Voice is one of the channels VoiceB agents use, alongside web and chat. But the product is the execution layer behind the conversation: the agent qualifies inbound demand, operates your CRM and internal systems, configures offers and can complete the sale autonomously. Inbound call automation is the surface; revenue execution is the product.
Query your systems in real time, check eligibility or coverage, retrieve pricing and product data, configure an offer, write to your CRM, generate and send a contract, and confirm completion.
Qualification is the first level of four. VoiceB agents also decide, execute against enterprise systems, and close.
Inbound and outbound voice over PSTN or a dedicated SIP trunk, WebRTC click-to-call, and a web widget.
It transfers to a human with the full conversation context, and the outcome is recorded either way.
Yes. You can create custom outcomes, reason codes, and routing rules so ASVA matches your sales operation and CRM taxonomy.
Typically 2–4 weeks depending on integrations and script complexity. We define baseline KPIs, run a controlled pilot, and only scale when outcomes are proven.
An ASVA is AI infrastructure that qualifies, routes, and closes inbound sales calls end-to-end — without a human agent. It is not a chatbot, IVR, or appointment setter. VoiceB's ASVA achieves a 30.4% autonomous close rate in live enterprise deployments.
VoiceB deploys autonomous inbound sales for telecom, energy, insurance, banking, and automotive enterprises. Current clients include Vodafone Spain, Holaluz, and SHV Energy.
Outcome-based. You pay for qualified demand, transferred calls, or closed sales — never seats or minutes. Invalid and non-sales calls cost €0 — you never pay for demand that can't buy. Full pricing: voiceb.ai/pricing.
Yes. VoiceB sends confirmed-sale conversion signals from the Outcome Engine back to Meta (Conversions API), Google Ads (offline conversion uploads), LinkedIn, TikTok and Microsoft Ads. VoiceB does not manage budgets or keywords — it supplies the sale-level signal so campaigns optimize toward revenue, not form fills.
