Retell AI deploys voice agents that dial your lists, deliver the pitch, qualify prospects, and book meetings around the clock. The agents place thousands of calls at once, connect to your existing phone system and CRM, and need no engineering team to launch. When a prospect is ready to talk to a person, the call hands off to a human rep with full context.
Trusted by over 3,000 businesses powering 30+ million calls per month.
How It Works

Launch an outbound campaign in four steps, from building the agent to dialing your list.

Build your campaign agent
Design the agent in a no-code flow. Set the opening, the offer, and the objection handling the way a sales playbook would, point it at a knowledge base for product and pricing questions, then connect your contact list and CRM and pick the voice and LLM that fit the audience.
Test against real scenarios
Run the agent against simulated calls before it dials a live number. Simulation covers gatekeepers, voicemail, objections, and wrong numbers, and you validate your do-not-call and calling-window rules and adjust the flow until the transcripts read the way you want.
Upload your list and launch
Upload the list and launch. Batch dialing places calls with no concurrency ceiling, so a 50,000-row list does not wait on a 12-rep floor, and the agent calls from a branded call ID, paces retries, skips dead numbers, and hands warm prospects to a rep the moment intent shows.
Monitor and optimize
Every call is transcribed, scored, and dispositioned automatically. Track connect rate, conversion, sentiment, and the exact point where calls drop through post call analysis, then feed that back into the script and scale only the lines that work.
Use Cases

Fill the pipeline without manual dialing

The agent dials each contact, opens with your pitch, and handles objections during the call instead of reading a flat script. It scores and routes prospects with lead qualification and writes the result to your CRM as the call ends, so reps inherit a clean, ranked queue and hot leads warm-transfer to a person on the spot.

Book and confirm meetings without phone tag

The agent calls leads to set appointments, offering open slots in natural conversation rather than a callback loop, and syncs each slot during the call to confirm or reschedule. Meetings land on rep calendars without the back-and-forth.

Win back no-shows and lapsed customers

Reminder and no-show win-back calls run automatically, recovering revenue that usually leaks from the calendar. Renewal outreach runs on the same schedule, so lapsed accounts get a call without a rep remembering to make it.

Recover revenue with compliant follow-up

The agent places payment-arrangement and renewal calls using compliance-safe scripting you define up front, and logs promises-to-pay, callbacks, and follow-ups straight to your system. Medical Data Systems runs high-volume debt collection this way, collecting roughly $280,000 a month with only a 30% transfer rate. Results vary.

Get past gatekeepers and hand off clean

The agent dials through phone trees and gatekeepers without manual input on each call, using navigate IVR to reach the right department or decision-maker. When the prospect is ready, the call transfers to a live rep with the full transcript attached.

Run outbound and inbound from one agent

The same agent that runs your campaign can flip to inbound as an AI answering service for callbacks and overflow, sharing one knowledge base and one CRM context across both directions.

Compliance

Outbound calling carries real regulatory risk, so the platform is built for it.

SOC 2 Type II

Call data runs on SOC 2 Type II certified infrastructure, so it clears enterprise security review.

HIPAA

Regulated outreach deploys under HIPAA with a self-service BAA portal available from the dashboard.

GDPR

Caller data is processed under GDPR, covering consent and access rights for prospects in the EU.

PII Redaction

Personal identifiers are redacted from transcripts automatically, with retention controls so you decide how much call data is kept.

FAQ

Frequently asked questions.

What is an outbound call center?

An outbound call center places calls to customers and prospects rather than waiting for them to call in, covering sales outreach, lead generation, appointment setting, surveys, renewals, and collections. Outbound call center solutions now run much of that work on AI voice agents that dial, talk, and act on each call without a person on every line. That removes the old cap on outbound, how many reps you can hire and train, by placing many calls at once while a smaller human team handles the conversations that need judgment.

Is AI outbound calling TCPA and DNC compliant?

Yes, when configured correctly. The agent honors do-not-call lists, calling-window rules, and opt-out requests inside the campaign setup, and records consent and disposition on every call. You stay responsible for your contact list and consent basis, the same as with human agents, while the platform enforces the guardrails you define.

Does it work with our existing phone system and dialer?

Yes. SIP trunking connects the agent to any carrier or telephony provider, so you keep your current numbers and infrastructure. You can route part of your outbound traffic to AI while your existing dialer and reps keep running, which makes a parallel pilot low-risk.

Will the AI sound robotic to the people it calls?

No. Voice agents respond in about 600ms with proprietary turn-taking, so they handle interruptions, pauses, and objections like a trained rep. Lifelike voices and natural backchannels keep prospects on the line instead of hanging up on an obvious bot in the first five seconds.

What happens when a prospect asks something the agent can't handle?

The agent escalates. It warm-transfers to a live rep with the transcript attached, or captures the question and schedules a callback. The same logic powers inbound support, so a prospect who calls back later reaches an agent with the earlier context already loaded.

How much does it cost compared to staffing agents?

You pay per minute of talk time, not per seat, so cost scales with conversations instead of headcount. There are no platform fees and no contracts, and idle list time costs nothing. A single agent can cover the call volume of multiple reps, which is where most of the savings come from.
