Why AI phone calls are never truly free
Every AI call uses real resources: a telecom carrier to connect the call, speech recognition to hear the caller, a language model to decide what to say, and a voice engine to say it. Each of those costs money per minute. A product that promises endless free AI calls is either capping you somewhere you have not noticed yet, or planning to charge you later.
That is not a reason to avoid free offers. It is a reason to read them as what they are: a trial. The useful question is whether the free part lets you test the thing you actually need — real calls, in your language, to real phones — before you spend anything.
What Outpero's 50 free credits buy
Every new account gets 50 free credits. One credit equals ₹1, and you are billed only for connected talk time. Here is roughly what that covers on each voice tier:
| Voice tier | Price per connected minute | Approximate talk time from 50 credits | Good for testing |
|---|---|---|---|
| Standard | ₹5 | About 10 minutes | Lead calling and qualification, the everyday use |
| Premium | ₹6.8 | About 7 minutes | Curated native-speaker voices with ultra-low latency |
Since test calls usually run one to two minutes, that is enough for several real conversations — enough to hear the voice in your language, try interrupting it, and see what lands in the dashboard. Free credits, like paid ones, never expire, so there is no pressure to use them in a week.
How to get the most out of a free test
- 01Write a short, real job description — the call you actually want made, not a generic demo.
- 02Pick the language your customers use and the Standard tier first; try Premium on one call to compare.
- 03Have the agent call your own mobile, and a colleague's, on ordinary mobile networks.
- 04Answer naturally: mix English in, interrupt, ask something off-script, give a vague budget.
- 05Read the transcript, summary and custom fields afterwards — that output is what your team will live with.
- 06Tighten the brief and run one more call to see the difference.
What it costs after the free credits
Once the 50 credits are used, you top up prepaid credits and keep paying only for connected talk time: ₹5 per minute on Standard and ₹6.8 on Premium. There is no setup fee, no monthly base fee, no contract and no lock-in. A dedicated phone number is billed separately at ₹649 a month, which includes compliance and carrier fees (prices exclude 18% GST).
Hear it on a real call before you read further?
For one-way messages, voice broadcast — a fixed recorded or synthesised message played to everyone on a list, with no conversation — is billed at a lower rate than AI minutes. It is the cheaper choice for announcements, but it cannot answer questions or capture a reply.
For perspective, the reference cost of one telecaller in India is about ₹18,000 a month for a single shift, handling one call at a time. At ₹5 a minute, ₹18,000 buys 3,600 connected minutes of AI calling, spread across as many channels as you add (₹649/month for each extra one).
What to test besides outbound calls
The free credits are not limited to one mode. If your business gets a lot of phone enquiries, test the inbound side too: the AI employee answers calls to your business number 24/7, handles the enquiry, qualifies the caller, books the appointment and logs it. Ring it yourself late in the evening and judge it the way a customer would. Note that it can transfer a call to your team when a person should take it; anything else it cannot resolve is flagged in the summary and webhook for your team to call back.
It is also worth checking the actions you plan to rely on. If the agent will book appointments, connect a test calendar and make sure the slot really appears. If it will send WhatsApp confirmations or write to a Google Sheet, watch those happen during the test call rather than assuming they will work later.
Other kinds of “free” you will see
- —Free plans with small monthly caps on minutes, which are useful for hobby projects but rarely enough for a business.
- —Free trials that need a card and convert to a monthly subscription unless cancelled.
- —Open-source voice-agent frameworks such as Pipecat or LiveKit Agents, which are free to download but still need paid telephony, speech, model and voice services, plus engineers to run them.
- —Browser demos that are free because they never touch a phone network — pleasant, but they tell you little about real call quality.
None of these are bad. Open-source frameworks in particular are a good fit for engineering teams who want full control. They are simply not the same as free calls to your customers.
Compliance applies to free test calls too
Test on your own phones and on colleagues who agree to it. Calling real customers counts as commercial communication under TRAI's TCCCP 2018 regulations whether or not you paid for the minutes, and their data falls under the DPDP Act 2023. Outpero calls from a DLT-registered line and screens DND numbers on bulk campaigns.
When a free trial will not tell you enough
A handful of test calls shows voice quality, latency and how well the agent follows your brief. It will not show pickup rates, how customers react at scale, or real conversion. For that, run a small paid pilot — a few hundred real leads over two weeks — and compare it with what your team achieved on similar leads. If most of your customers prefer Bengali, Gujarati, Punjabi or Odia, which are not live, the free credits will show you that quickly too.
