Outbound AI calling: an auto caller that holds the conversation
An auto dialer plays a recording or waits for a free human agent. An AI auto caller talks: it confirms the order, answers the question, takes the reply and logs the outcome, in Hindi, English and other Indian languages. Campaigns run in Sonex Flows at $0.055 per minute.

Dialer vs AI agent
Auto dialer, predictive dialer or AI calling agent?
All three dial from a list. They differ in who talks once the call connects.
| Auto dialer / voice broadcast | Predictive dialer | AI calling agent | |
|---|---|---|---|
| Who talks | A recorded message | A human agent, once one is free | The AI agent, on every call |
| Can it answer questions | No | Yes, if an agent is free | Yes, and it can look things up during the call |
| Captures the reply | Keypad input at most | The agent types notes | The outcome and a transcript, written to your CRM |
| Languages | One recording per language | The languages your team speaks | Hindi, English and other Indian and world languages, detected automatically |
| Cost driver | Per call or per minute | Agent salaries plus dialer seats | $0.055 per minute of call |
If you only need to play the same message to everyone, a voice broadcast (voice blast) is enough. Use an agent when the call needs a reply: a confirmation, a reschedule, a payment date.

Calls go out only in the hours you allow, in the time zone you choose. - 03
Set retry limits and back-off

Rupee, dirham and riyal figures use ₹95.04, AED 3.6725 and SAR 3.75 per US dollar (open.er-api.com, 24 October 2026). They are for planning only. Model your own volumes with the cost calculator.
Rules
Check the calling rules before you launch.
In India, commercial calls must come from the right number series and follow TRAI's rules for automated and A2P calls. Read TRAI's 140, 1600 and 1601 number series and TRAI's rules on robocalls and commercial calls, or use the number series picker to see which series applies to your calls.
Calling other countries? AI calling rules by country covers disclosure, consent and calling hours, and the UAE rules for AI sales calls set a 9 am to 6 pm window. Open each call with a line from the AI disclosure and recording-notice scripts.
Ready-made outbound scripts: COD confirmation, EMI reminder, collections, delivery and more. Replacing a telecalling team? See the AI telecaller cost comparison.
FAQ
Outbound AI calling, answered.
An auto dialer dials numbers from a list and either plays a recorded message or connects the answered call to a human agent. An AI calling agent dials and then holds the conversation itself: it answers questions, takes the reply and records the outcome, and transfers to a person only when needed.
No. A predictive dialer paces calls for a team of human agents. On Sonex the AI agent places and handles each call itself, and transfers live to your team when a person is needed.
Yes. Each campaign in Sonex Flows has a calling window and a time zone, so calls only go out in the hours you set.
You choose. Set a retry limit and a back-off between attempts for each campaign, so unanswered numbers are tried again later rather than straight away.

From the numbers in the telephony account you connect.
