How many concurrent calls should an AI campaign run?
Start a new campaign at low concurrency — around three to five calls at once, which means three to five channels — while you check transcripts, then add channels once results look right. The right number depends less on the AI than on your team: how many hot leads, callbacks and visits they can handle in an hour, and how many calendar slots are available.
Suggested settings by situation
| Situation | Suggested channels (calls at once) | Why |
|---|---|---|
| New script, first day | 3–5 | Catch problems before they repeat thousands of times |
| Proven script, small team for follow-up | 5–10 | Hot leads arrive at a pace the team can call back |
| Reminders or confirmations | 10–20 | Little follow-up needed; finish the list fast |
| Large list, short calling window | 15–20 | Cover the list inside the window |
| Booking into limited slots | Low to medium | Avoid offering slots that fill mid-campaign |
A simple ramp
- 01Day one: low concurrency, read the first 20–30 transcripts the same day.
- 02Fix what breaks and run again.
- 03Add channels in steps once two consecutive days look clean.
- 04Watch the downstream signals: callback backlog, unbooked hot leads, calendar fill.
Follow-up capacity is the real limit
Twenty channels, meaning twenty calls at once, can surface dozens of hot leads an hour. If two people handle callbacks, many of those leads will wait until tomorrow and cool down, which wastes the speed you paid for. Match concurrency to the slowest step in the chain.
Account-level limits
On Outpero, concurrency is sold as channels: a channel is one call at a time on your number, the ₹649/month number includes 1, and each extra channel is ₹649/month, added or removed any month, for instant, bulk and inbound calls alike. Running two campaigns at once — say, admission follow-ups and fee reminders — needs 2 channels, so 2 × ₹649 = ₹1,298 a month, before 18% GST.
You pay only for connected talk time, at ₹5 or ₹6.8 a minute depending on the voice tier. A thousand minutes costs the same on 3 channels or 20; channels only change how quickly the list is finished, and each one beyond the first is ₹649/month.
