Business Case: Vodafone Spain × VoiceB.ai
By Alex Bisbe. November 27th 2025.
Overview
Vodafone Spain partnered with VoiceB.ai, an AI voice platform designed specifically for inbound sales, to automate lead qualification, routing, and conversion in its consumer acquisition funnel. The goal: replace manual screening with an intelligent voice layer capable of engaging, qualifying, and transferring calls in real time — without human intervention and without sacrificing sales performance.
Challenge
Vodafone’s inbound traffic exceeds 40,000 monthly calls, a mix of high-intent prospects and existing customers. Traditional IVR and call-center screening created friction:
Long wait times and repetitive menus led to drop-offs.
Low-value or invalid leads consumed significant agent time.
Operational costs scaled linearly with call volume.
Vodafone needed to reduce human workload and preserve conversion, ensuring high service quality and seamless user experience.
Solution: VoiceB.ai
VoiceB deployed “Rosa,” an AI voice agent trained on Vodafone’s real scripts, tone, and qualification logic. The system handles the full inbound flow:
Detects and filters invalid or existing-customer calls automatically.
Transfers only qualified leads to live agents in real time.
Operates 24/7, managing off-hour leads and re-engaging dropped calls.
VoiceB replaces the traditional IVR, creating a direct, conversational path from inquiry to sale.

What VoiceB Delivers Today
Forms → Frictionless Conversations Consumers don’t want to fill out forms or wait for callbacks. VoiceB replaces manual flows with natural, real-time conversations that qualify and route instantly.
Voice as the Interface The shift from Click & Type to Speak & Solve is here. VoiceB enables instant product explanations, plan recommendations, and live transfers.
Zero-Wait Standard (24/7) Calls are answered in under 4 seconds, day and night. Low-intent, invalid, and duplicate calls are filtered automatically.
Frictionless Journeys Voice-guided onboarding and structured data collection reduce drop-off and accelerate time-to-sale.
Humans Elevated AI handles volume and repetition. Human agents focus only on high-value conversations where persuasion and complexity matter.
What’s Next — Hyper-Individualized Sales
This is our next leap: AI that remembers.
Hyper-Individualized Sales means:
VoiceB stores and recalls previous interactions, intent, objections, and context.
Messaging and tone become fully adaptive, personalized to the caller’s history.
Offers, scripts, and follow-ups are context-aware across sessions and channels.
Sales journeys become continuous, not isolated — “Rosa” knows the user before the conversation even starts.
This transforms the AI agent from a reactive qualifier into a persistent sales companion capable of higher trust, higher relevance, and higher conversion.
Team & Vision
VoiceB is founded by industry veterans in conversational sales technology. CEO Álex Bisbe previously led Whisbi, the pioneer in real-time video sales for enterprises like Vodafone, AT&T, Verizon, Telefónica, Toyota and Hyundai. The team combines deep expertise in telecom sales, AI orchestration, and voice infrastructure, with a vision to transform inbound contact channels into fully automated, revenue-generating systems.
VoiceB’s mission is clear:
“To make every inbound conversation instantly solvable — by voice.”
Next Steps
With a proven pilot, Vodafone is now evaluating full deployment of Rosa across 100% of inbound traffic, replacing the IVR layer. Expected impact:
€13K+ monthly operational savings
Consistent conversion performance
Scalable 24/7 customer acquisition channel
