How many calls can an AI voice agent handle at once?
An AI voice agent can handle many calls at once, because each call runs as a separate instance of the same software, unlike a person who can take one call at a time. The practical limit is set by the platform's concurrency and phone lines. Outpero sells concurrency 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.
Why AI scales differently
A human telecaller handles one conversation at a time and works one shift. An AI agent is software: the same instructions, voice and tools can run in parallel on several calls, each with its own transcript and memory. Calls do not share attention, so one caller never affects another.
What actually limits concurrency
- —Telephony capacity: each live call needs a channel on the phone line or trunk.
- —Platform compute: recognition, reasoning and speech synthesis must run for every active call at once without slowing replies.
- —Your own systems: a calendar or CRM receiving many simultaneous writes must keep up.
- —Regulation and good practice: calling windows and DND rules limit when and whom you call, whatever the capacity.
Concurrency and latency
Running more calls at once is only useful if each call stays responsive. A platform that slows to three-second replies under load has, in practice, lower capacity. When testing, run a small campaign at your intended concurrency and listen to a few calls to check that timing holds up.
How to choose a level
Higher is not always better. If your sales team must call back hot leads within an hour, running 20 channels at once can produce more qualified leads than they can handle. Match concurrency to how fast your team can act on the results. For instant lead callback, concurrency mainly ensures new enquiries are not queued during busy spells, such as just after an ad campaign goes live.
Outpero's limits
| Setting | Limit |
|---|---|
| Calls at once | One per channel (a channel is one call at a time) |
| Included channels | 1, with the dedicated number at ₹649/month |
| Extra channels | ₹649/month each, added or removed any month |
| New lead callback | Within 30 seconds of the enquiry |
For comparison, a human telecaller in India costs roughly ₹15,000 to ₹25,000 a month, works one shift and handles one call at a time.

Follow-up questions
Does running more calls at once cost more?
+
Not per minute. Outpero charges for connected talk time from prepaid credits, so the same number of minutes costs the same whether calls happen on one channel or twenty. Concurrency changes how quickly a list is finished, not the price per minute. Each channel beyond the first is billed at ₹649 a month.
