Meta Tech ProviderVoice Campaigns
Outbound AI voice campaigns for the US, UK, UAE and India
Let your AI agent call your list for reminders, lead qualification and customer updates — with pacing, smart retry, voicemail detection, callbacks and calling hours you set on each person's local time.
In short
What is an outbound AI voice campaign?
It is a list of people your AI agent phones for you, one natural conversation each, with the outcome of every call recorded. You upload the list, pick the agent and the hours, and the campaign dials at the pace you set.
It works for businesses in the US, UK, UAE and India, with the same agent that answers your inbound calls, WhatsApp and website chat.
What calling hours does a campaign follow?
The hours you set. You choose calling hours per campaign (or per API call), on the called person's local time — set them to what the law requires where you call, for example 08:00–21:00 under the US TCPA or 09:00–21:00 under India's TRAI rules.
A callback someone asks for ("call me after five") is booked within the same calling hours, and you can cancel it from the console.
Who is responsible for consent and Do Not Call screening?
You are. You are responsible for having consent to call each person and for screening your list against the Do Not Call registries that apply to you — such as the US National Do Not Call Registry, the UK's TPS, or India's NCPR. ThinnestAI does not screen lists against any registry.
The product gives you tools such as a do-not-contact list you keep, which every campaign respects, and it never re-dials someone who declined a call.
Which phone numbers can a campaign call from?
Outside India, you can rent a US number from us, which calls US and Canada numbers only, or import a number you already own from your Twilio, Telnyx or Plivo account; UK and UAE numbers are import only. In India, you can buy an Indian number from us or import your own.
Spread calls across several numbers so no single one is flagged, and the same person always hears from the same number. Voicemail detection works on our Indian numbers and on imported Plivo and Telnyx numbers. See pricing for campaign minutes.
Use cases
High-Volume Outbound Campaigns
Replace manual dialling with voice campaigns that speak your customers' language — English in American, British, Australian and other accents, Arabic, Spanish, Hindi and more — and capture structured outcomes.
Payment Reminders & Collections
Call customers about an overdue invoice or instalment in their own language. The agent explains what is due, notes the date they promise to pay as a field, and books a callback if they ask for one.
Lead Qualification
Call new form fills and enquiries while they are still warm. The agent asks your qualifying questions, records the answers as typed fields, and sends the result to your CRM by webhook.
Appointment & Service Reminders
Remind patients, clients and car owners about a booking. Collect a confirmation or a request to move it, in natural speech.
Order Confirmation
Confirm high-value or cash-on-delivery orders before dispatch, so the customer is home and still wants it.
Event & Webinar Reminders
Call registrants before a session starts with a personal reminder, the opening line filled from your spreadsheet for each person.
Customer Feedback Calls
Ask a few short questions after a delivery or a resolved ticket and keep every answer next to the call's transcript.
Infrastructure
Intelligent Auto-Dialling Infrastructure
Built to protect your numbers and your customers' evenings: paced dialling, retries that know when to stop, and a do-not-contact list every campaign respects.
01
Smart Retry & Pacing
A busy line is retried in minutes and an unanswered one after an hour or more; someone who declined, or a dead number, is never re-dialled. Cap calls per rolling hour and choose the weekdays, on each person's own clock.
02
Call Outcomes, Not Call Counts
See connect rate, average talk time and why calls failed — busy, declined, unreachable or voicemail. Results reach your CRM through signed webhooks.
Turn-by-turn transcript
03
Recording & Transcripts in the Call Log
Every campaign call lands in the call log with its transcript and, when recording is switched on for the agent, playback. Export the log as CSV.
04
Audience Upload & the Calls API
Upload contacts from a spreadsheet; any column (name, amount due, due date) can fill the opening line and the agent's instructions per person. Or queue calls from your own systems through the REST API.
Related: call recording, transcripts and call logs, cross-channel memory and the AI receptionist for inbound calls.
FAQ
Voice Campaigns FAQs
How many calls can a campaign place at once?
+
Calls go out as your lines free up, within the hourly cap you set for the campaign. We do not publish a throughput figure: how many run together depends on your plan and your numbers. A person is never rung twice at the same time.
What happens if someone doesn't answer?
+
Smart retry tries a busy line again in minutes and an unanswered one after an hour or more. If voicemail picks up, the agent can leave a campaign-specific message instead of talking to a machine. If the person rings back, the agent recognises the number and has the earlier call in its memory.
How are campaign calls billed?
+
Campaign calls are billed at the voice rate for your plan. Rates and plans for India and for international workspaces are on the pricing page.
Can I test two opening lines?
+
Yes. An A/B test sends two opening lines to complementary halves of one audience, so you can see which one keeps people on the call.
What does the product do about telemarketing rules?
+
It gives you the controls: calling hours on each person's local time, weekday limits, an hourly cap, and a do-not-contact list. Setting them to match the law — calling hours, consent, registry screening, caller identification and any telemarketer registration — is your responsibility under the rules where you and your customers are.
