VOICE, MEASURED
IVR bulk voice calling that tells you who actually listened
Play a pre-recorded clip to thousands of numbers, see how long each person listened, and connect anyone who presses 1 to your team.
QUICK ANSWER
IVR bulk voice calling sends a pre-recorded voice message to a large list of phone numbers at once. Smart Growth AI adds listen-duration tracking, so you know who hung up at 3 seconds and who heard the whole clip, plus press-1 transfer to a live agent. Each listener's duration and key press becomes a lead score you can act on.
01
Listen time = interest
See exactly how many seconds each person listened. It is a far better signal than 'call answered'.
02
Press 1, talk to us
Interested listeners press 1 and are connected to a live agent straight away, while the interest is fresh.
03
Test two clips, keep the winner
Run two voice clips and the AI report shows which one held attention and produced more leads.
Why voice still works in India
A phone call cuts through in a way a message rarely does. It rings. People pick up. And for a lot of your audience, whether parents in tier-2 towns, older patients or busy professionals, hearing a clear, friendly voice explain an offer in 30 seconds is easier than reading a long message.
The problem with old-style voice blasting was that you never knew what happened after "answered". Did they listen? Did they cut the call in two seconds? Smart Growth AI fixes that.
Listen-duration tracking, explained
For every answered call, we record how many seconds the person stayed on the line. That one number tells you a lot:
- Under 10 seconds: they heard who was calling and dropped off. Probably not interested right now.
- 10 to 25 seconds: they listened to part of the pitch. Curious, but not convinced.
- 25 seconds and above: they stayed for most or all of a 30-second clip. That is real attention.
Combine that with whether they pressed a key, and you have a simple, honest lead score without anyone filling a form.
How a voice campaign runs
1. Write and record the clip
Keep it around 30 seconds. Say who you are in the first few seconds, give one clear reason to listen, and end with the action: "Press 1 to speak to a counsellor now." We help with scripts and can suggest how to record two versions for testing.
2. Upload your list and set the pace
You choose how fast calls go out based on how many agents you have. A common setting is 1,000 calls every 10 minutes connected to 5 live agents, so the team is busy but not swamped.
3. Press 1 goes live
Anyone who presses 1 is put through to an available agent. The live agent transfer page explains how that handoff works.
4. Automatic follow-ups
Everyone who answers gets an SMS with your callback number. Depending on listen time, people can also get an RCS carousel or a WhatsApp template with videos.
5. Read the report
You see answered calls, listen-duration bands, key presses, and leads in a Google Sheet, along with which clip did better and your cost per lead.
The opening move of the Smart Growth AI Campaign
IVR is step one of the Smart Growth AI Campaign for a reason. A voice call is one of the cheapest ways to touch every person on a large list, and listen duration tells the AI exactly where to spend on richer follow-ups. Short listeners get nothing extra. Medium listeners get RCS. Long listeners get WhatsApp videos. People who press 1 get a human.
Where it fits
Admission campaigns for coaching centres and colleges. Health camp and check-up announcements for hospitals. Renewal or pre-approved offer calls for insurance and lending teams. Event and open-day invites. Anywhere a short spoken message can do the first round of sorting for you.
Being a good caller
Call at reasonable hours, keep the clip short, and make opting out easy. Every voice campaign supports opt-out so people who do not want calls are excluded next time. It is better for them and better for your answer rates.

FAQ
Questions people ask
What is IVR bulk voice calling?
It is an automated way to play a pre-recorded voice message to many phone numbers at once. Listeners can press keys to respond, for example pressing 1 to speak to someone. It is commonly used for admissions, offers, reminders and announcements.
What is listen-duration tracking?
For every answered call, the system records how many seconds the person listened. Someone who heard 25 seconds or more of a 30-second clip is far more likely to be interested than someone who hung up after 3 seconds, so this becomes a simple lead score.
How many calls can go out at once?
It depends on your agents and goals. A common setting we use is 1,000 calls every 10 minutes connected to 5 live agents. If you have more agents, the pace can go up; if fewer, we slow it down so press-1 callers are not left waiting.
How long should the voice clip be?
Around 30 seconds works well. Say who you are early, give one clear reason to listen, and end with a simple action like pressing 1. We help with the script and suggest recording two versions so the report can show which performs better.
Can people opt out of voice calls?
Yes. Opt-out is supported on voice just like on SMS, WhatsApp and RCS. People who opt out are excluded from future campaigns, which keeps your lists cleaner and your answer rates healthier.
