How It Works
Go from build to a live call in a day, on your existing number.
Build the agent
Point the agent at your offers, pricing, and qualification criteria through a knowledge base that syncs as that content changes. Define the call flow with a drag-and-drop builder — greeting, intent detection, qualification questions, routing rules, and transfer conditions — then connect your calendar and CRM. No engineering team is required for a standard agent.
Test against qualification scenarios
Run the agent through simulation against common scenarios before it touches a real prospect: a strong-fit lead, a poor-fit lead, a caller who won’t share budget, and an ambiguous inquiry. Each run scores accuracy and shows where the agent guesses instead of looking up, so you fix the flow, rerun, and validate at volume.
Connect your line and go live
Connect your line through SIP trunking and forward calls to the agent — all of them, only the ones you miss, or only after hours — and set the routing and human-escalation rules. Go live, confirm your qualification and transfer rates, then expand. Your existing carrier and phone number stay in place.
Monitor and retrain
Every call is transcribed, summarized, and tagged by outcome, and every qualified lead lands in your CRM. Watch qualification rate, transfer rate, and speed-to-lead in a dashboard, catch the questions the agent fumbles, and retrain the flow, with quality review across 100% of calls rather than a small sample.
Use Cases
How AI lead qualification works across your call flow
Qualify inbound leads on every call
The agent picks up the moment a lead calls, identifies why they’re phoning, and qualifies them in natural conversation against your criteria, so no inbound lead sits in a queue or rolls to voicemail — even at nights, weekends, and peak volume.
Route hot leads with a warm transfer
The agent gathers the details you need and routes hot leads to the right person with a warm call transfer that attaches the full transcript, so sales reps pick up a qualified, context-rich conversation instead of starting cold.
Sync qualified leads to your CRM
Retell AI integrates with popular CRM platforms and sales tools, transferring qualified leads directly into your existing workflows and keeping all lead information organized in one place.
Qualify across phone, text, and email
Retell AI interacts with leads across multiple channels, including phone, text messages, and email, so you can capture and qualify leads wherever they reach out and expand your reach.
Follow up and re-engage by phone
The agent runs follow-up, nurture, and re-engagement calls through batch call campaigns, reaching aged or unworked leads at scale and logging every outcome to your CRM with the transcript attached.
Capture leads after-hours and on overflow
When your team is busy or offline, the agent fields overflow and after-hours inquiries so a lead that arrives at 9 PM on a Saturday is qualified and routed instead of lost to a competitor who answered first.

Feature
Why businesses choose Retell AI for lead qualification
Qualifies on your criteria
Retell AI uses your specified criteria — budget, project scope, and timeline — to evaluate each lead’s responses, tailoring its questions to gather the details that matter and qualifying only the leads that match your ideal profile.
Personalized, natural conversations
Retell AI adapts to each lead’s responses, making every interaction feel personal and relevant. This customized approach improves the prospect’s experience, making them more likely to view your business as attentive and trustworthy.
Responds the moment a lead comes in
With end-to-end latency of about 600ms and answering around the clock, Retell AI engages a lead the instant they reach out — and speed-to-lead is the strongest predictor of whether a lead converts. Results vary.
Automates outreach and screening
Retell AI automates repetitive tasks like initial outreach and information gathering, freeing up sales reps to focus on high-value activities. This automation reduces burnout, optimizes productivity, and keeps your team constantly moving forward.
Scores 100% of calls and lifts conversion
Every call is transcribed, summarized, and tagged by outcome through post-call analysis, and qualified leads sync straight to your CRM. By focusing your team only on qualified leads, Retell AI improves conversion rates — your reps spend less time screening and more time closing deals.

FAQ
Frequently asked questions.
What is AI lead qualification?
AI lead qualification uses a voice agent to call or answer leads, run a real qualification conversation, and decide whether each one fits your criteria — then capture the details and route the qualified ones to a rep. Unlike a static web form or a touch-tone menu, it understands intent, asks follow-up questions, and takes action during the call, applying the same discovery framework to every lead, 24/7.
How does Retell AI know if a lead is qualified?
Retell AI uses your specified criteria to evaluate each lead’s responses, such as budget, project scope, and timeline. It tailors its questions to gather relevant information and only qualifies leads that match your ideal profile.
Will Retell AI work with our CRM or sales tools?
Yes, Retell AI can integrate with popular CRM platforms and sales tools, making it easy to transfer qualified leads directly into your existing workflows. This seamless integration saves your team time and keeps all lead information organized in one place.
Can Retell AI support multi-channel lead qualification?
Yes, Retell AI is designed to interact with leads across multiple channels, including phone, text messages, and email. This flexibility means you can capture and qualify leads wherever they reach out, improving the customer experience and expanding your reach.
How much time does Retell AI save for sales teams?
Retell AI reduces the need for manual lead screening, often saving sales teams hours per week. By handling repetitive tasks and providing qualified leads, it allows your sales team to focus more on closing and nurturing relationships with serious prospects.
How much does it cost?
Retell is pay-as-you-go at $0.07 per minute with no platform fee or contract, plus free credit to start. You pay for minutes worked, not seats, which is why a busy line still costs less than a part-time SDR. For companies with large volumes, or data, deployment, or support requirements, an Enterprise plan adds white-glove service, a dedicated solution engineer team, and custom pricing and concurrency.
Does it sound like a real person?
Most callers do not realise they are speaking to software, and the fastest way to judge it is to hear a call rather than read a claim. The agent responds in under a second, handles interruptions, and does not talk over the caller. You choose the voice, and you can disclose that it is an AI agent at the start of the call if you prefer.
Do I build it myself, or do you build it for me?
Both are real options and this is the question prospects ask most often after the voice itself. Engineering teams build directly on the Retell API and SDK and connect their own telephony. Teams without engineers work with our implementation team and go live without writing code.
What happens when the agent does not know the answer?
It transfers to a person and passes the full context, so the caller does not have to repeat themselves. You set the escalation rules, including which questions always go to a human and which lines they route to. The agent escalates rather than guessing when a request falls outside what it has been given.
Can I use my existing phone number?
Yes. You can port your existing number to Retell or forward it, and callers keep dialling the number they already have. Buying a new number is also available, which is the option most people notice first in the interface. You can run the agent on one line or one location before extending it to the rest.
Can I monitor calls live?
Yes. You can listen to a call while it is in progress, and take it over if you want to. Every call is transcribed, scored, and dispositioned automatically after it ends. You can review the calls the agent handled badly and retrain it from those recordings.
