AI Voice Agent for Lead Qualification — DeepAgent
In 3 months, VEGA transformed 49.8% of conversations into qualified leads: don't let the first contact wait. Want to see how it integrates into your funnel?
If you lead a sales team, you know where opportunities are lost: not during negotiation, but in the time between an information request and the first phone call. From May to July, we placed VEGA, our AI voice agent for lead qualification, exactly at that point — the entry of DeepAgent's funnel. In 3 months: **7,290** call attempts, **3,030** completed conversations, **1,510** initiated sales processes. On actual conversations, the success rate is **49.8%**; in July, it rises to **56.6%**. ## TL;DR - VEGA calls inbound leads back and pre-qualifies them: **49.8%** success rate on conversations. - **7,290** attempts, **3,030** conversations, **1,510** useful outcomes in 3 months. - **88 hours** of dialogue: one useful outcome every **3.5** minutes spoken. - Growing monthly conversion: July at **56.6%**. - Clean handoff to sales: context, contact details, and priority already gathered. ## Context and Goals: We Are Our Own Client (DeepAgent) DeepAgent builds AI agents for repetitive sales tasks: first contact, qualification, follow-ups, routing. Every day we receive inquiries from companies wanting to understand if a voice agent works in their process. The most rigorous test is to use it on ourselves: from May 1st to July 31st, VEGA was positioned at the entry of our funnel to reduce time to first contact and deliver pre-qualified requests to sales. Result: **7,290** attempts and **88 hours** of real conversation.  ## The Challenge: The First Contact Bottleneck ### Short Attention Window A request has a narrow window: if the callback comes the next day, the contact has already looked elsewhere. Automatic callback of inbound leads is the difference between speaking with a person and reaching an answering machine. ### Repetitive Questions, Limited Time Process to improve, volumes, channel, urgency, decision-makers: these are always the same questions. Asking them manually consumes sales time on low-value activities. ### Not All Requests Are Projects Exploratory contacts, non-decision-makers, forgotten forms: without a filter, they end up with the sales team, slowing them down. ## The Flow of an AI Voice Agent for Lead Qualification: From Request to Handoff - **01 · Contact.** The lead submits a request on DeepAgent. VEGA calls back, verifies the interlocutor and timing. - **02 · Listening.** Explores context, target process, and current operational workload. - **03 · Pre-qualification.** Gathers use case, volumes/typology, channel, urgency, maturity, stakeholders. This is automated sales pre-qualification: natural conversation that produces structured data. - **04 · Handoff.** Confirmed contact details and organized context for the salesperson; if it's not the right time, preferred callback time is collected. ## Results and Metrics (May 1st – July 31st) | Metric | Value | |---|---| | Call attempts on inbound leads | **7,290** | | Completed conversations | **3,030** · 41.6% of attempts | | Positive outcomes passed to sales | **1,510** | | Success on real conversations | **49.8%** · 1 outcome every 2.0 calls | | Success on total attempts | **20.7%** | | Conversation time | **5,309 min** · 88 hours | | Useful outcome every | **3.5** minutes spoken | The key number is the **41.6%** of attempts that become real conversations: with recent inbound leads, you genuinely speak with people. And when you do speak, almost half the time, progress is made. ### Monthly Trend | Month | Positive outcomes / conversations | Success rate | |---|---|---| | May | 360 / 750 | **48.0%** | | June | 550 / 1,220 | **45.1%** | | July | 600 / 1,060 | **56.6%** | The improvement doesn't come from volume — July has fewer conversations than June — but from refining qualification questions and managing unavailability.  ## How VEGA Speaks: Follow-up, Not Telemarketing - Starts from the request, not an offer: professional tone, zero pressure. - If the contact is not ready, it collects a preferred callback time and does not force. - Clarifies the scope of use for voice agents without replacing consultation. Recurring themes: first contact automation, lead qualification, use cases, volumes and operational workload, demo requests, integration with existing processes, project timing. Out of scope: those who don't answer, don't remember the request, or are not the right contact — work that an AI voice SDR for first contact takes off the table.  ## Impact for Team, Costs, and Leads - **Team.** The salesperson starts with context, not just a name: use case, volumes, channel, urgency, and maturity are already collected. No hours spent dialing numbers or filtering. - **Costs.** Capacity scales: **7,290** attempts in three months without hiring or overtime. - **Leads.** The callback arrives when interest is high; those not ready are re-engaged at the right time. ### Related Insights - Trading case study: [AI Voice Agent for Trading](https://deepagent.app/caso-studio/agente-vocale-ai-trading/) - General overview: [AI Voice Agent: What It Is and How It Transforms B2B Sales](https://deepagent.app/blog/agente-vocale-ai-cose-e-come-trasforma-vendite-b2b/) ## Methodological Note By "positive outcome," we mean an advancement in pre-qualification or an initiated sales handoff; not a closed sale or attributed revenue. 24/7 continuity, CRM integration, and agenda management are platform functions but are not presented here as measured results. ## Conclusion From May to July, VEGA generated **1,510** useful outcomes from **3,030** completed conversations (49.8%), with July reaching **56.6%**. This is the real scope of an AI voice agent for lead qualification: accelerating the first contact and gathering context, leaving negotiations to the salesperson. Want to see it in your process?

Costs depend on volumes, languages, integrations, and the complexity of automated sales pre-qualification. Generally, a platform fee is combined with a per-conversation/minute cost. ROI is measured against callback SLAs, time saved for sales, and inbound lead conversion rates. We offer a demo with real data. ### What integrations are needed with CRM and calendars? CRM integration is recommended to align contacts, notes, and pipelines after the sales handoff. We support webhooks, REST APIs, and standard connectors to major CRMs; optional agenda synchronization for booking meetings. Field mapping includes use case, volumes, channel, and urgency, collected during the call. ### How is the success of an AI voice SDR measured? Typical KPIs: conversation rate on attempts, success rate on conversations, time to first call, minutes spoken per useful outcome, meeting show rate after handoff. We compare these KPIs with human baseline and automated inbound lead callback SLA to measure real impact. ### How customizable are the voice and qualification flow? Voice, tone, language, and questions are customizable for market and buyer persona. The qualification flow adapts to use cases, volumes, channels, and priority criteria; it includes unavailability management and scheduled callbacks. We train the agent on client data and comply with internal policies and compliance. ### In which sectors does it work best? And when is it not suitable? It performs best in B2B tech, software services, consulting, and sectors with qualified inbound leads. It is not suitable when the average value is very low or the preferred channel is not voice. In these cases, it can be used for light triage or transferred to other channels while maintaining the AI voice SDR as the first point of contact. ### How do you handle GDPR and privacy in calls? We apply privacy by design principles: information at the outset, data minimization, limited retention, and encryption in transit and at rest. We provide controls for consent, opt-out, and audit trails. CRM integration synchronizes only the necessary fields for qualification and sales handoff, in compliance with GDPR.
