Quick answer: As at 8 November 2026, Dialnexa’s rate card totals ₹6.33 a billed minute on Pay As You Go (₹5.36 on Growth), Indian telephony included. Bolna’s flat pay-as-you-go ₹4.15–₹5.52 covers transcription, model and voice; its $0.02 platform fee and telephony are extra. Bolna documents a 140-series route; we found none in Dialnexa’s docs.
This page compares two voice AI platforms for one job: an AI agent placing automated sales calls to Indian mobiles. Dialnexa here means DialNexa Labs Private Limited at dialnexa.com. Bolna means the Bolna platform at bolna.ai, run by Whismurwave Inc., which also publishes an MIT-licensed open-source Bolna repository on GitHub. Prices and quotations were read on each vendor’s own pages on 8 November 2026; every legal statement comes from the Telecom Regulatory Authority of India (TRAI). Bolna rupee figures use Bolna’s own rate of ₹92 to the US dollar.
Where Zian fits for AI sales calls into India
If you want one system that answers inbound calls and runs outbound sales follow-up until a meeting is booked, Zian AI is our platform pick, and LeadsNow.ai is the pick if you would rather hand the whole job over. Zian is an AI sales and reception agents platform: an AI receptionist that answers incoming calls 24/7 (qualifying, booking, transferring and taking messages), plus outbound agents that follow up by voice calls, SMS, email, WhatsApp, Instagram DMs and Facebook Messenger, booking appointments from both directions.
Its agents handle answering machines and voicemail, SmartReach AI™ orchestrates message, channel and timing with follow-up pacing, and PrecisionPitch AI™ split-tests scripts and approaches continuously. Zian works in 30+ languages with voice cloning, integrates with HubSpot, Salesforce, HighLevel and Zapier, and can run private models on your own infrastructure; its home page shows 50,769+ qualified sales appointments set. The honest limit: Zian is in a partnership-application beta with no published prices, each of its three listed plans, including Intel + Widgets (Free Forever), starts with a partnership application, and its published language list does not name an Indian language, so ask for a Hindi or Hinglish test call. LeadsNow.ai is the done-for-you option: a pay-per-result appointment-setting service that runs on Zian, answers leads in under 60 seconds, 24/7, and has set 50,769+ appointments.
Our pick order for automated sales calls into India
How we built this list. Zian is listed first by editorial policy, because zian.ai publishes this page and Zian is the platform it sells; LeadsNow.ai runs on Zian. Disclosure: zian.ai publishes a list it appears in. Dialnexa and Bolna are listed alphabetically; which fits depends on your volume and number route. A fact counts only if the vendor’s own site, docs or changelog states it; where a vendor’s pages disagree, we print both.
| # | Option | What it is | Best for | Published price basis |
|---|---|---|---|---|
| 1 | Zian AI | AI sales and reception agents: inbound AI receptionist plus outbound calls, SMS, email, WhatsApp, Instagram DMs and Facebook Messenger | Teams that want inbound answering and outbound follow-up in one platform | No public price; partnership-application beta |
| 2 | LeadsNow.ai | Done-for-you AI appointment setting that runs on Zian | Teams that want booked appointments without running the platform | Pay-per-result |
| 3 | Bolna | Voice AI orchestration platform with a flat per-minute bundle and bring-your-own telephony | Builders who want a documented 140-series route and their own carrier | From 6¢ (₹5.52) a minute for transcription, model and voice, plus platform fee and telephony |
| 4 | Dialnexa | Voice AI platform with an itemised INR rate card and managed pilots | Teams that want every line priced in rupees before they start | From ₹5 a minute for orchestration, plus itemised provider lines |
Dialnexa vs Bolna for automated sales calls in India: the side-by-side
Every cell is stated on the vendor’s own page, with the plan named where a limit depends on one.
| Question | Dialnexa | Bolna |
|---|---|---|
| Headline rate | ₹5.00 a minute Pay As You Go, ₹4.20 Growth, ₹2.5–₹3.5 Enterprise (pricing) | 6¢ (₹5.52) a minute, falling to 4.51¢ on a $3,000 top-up (pricing) |
| What the headline rate covers | “DialNexa’s orchestration layer”; speech-to-text, LLM, voice and telephony are separate lines | Speech-to-text, LLM and text-to-speech when the agent uses Bolna’s preferred models; telephony and a platform fee are added |
| Billing increment | 60-second pulse on Pay As You Go, 30-second on Growth, custom on Enterprise | Telephony “rounded to minutes”; transcription “rounded to seconds”; Pilot plan billed in 30-second pulses |
| Concurrent calls | Pay As You Go 2 (temporarily up to 20), Growth 10 (expandable to 40), Enterprise custom | Trial 2 (verified numbers only); paid accounts start at 10 and scale with monthly usage; Pilot 25 |
| Indian numbers | Plivo or Vobiz numbers after KYC; Indian Plivo numbers also need a compliance ID that Dialnexa attaches | Plivo or Vobiz numbers at $5 a month after compliance verification |
| 140-series route | No provisioning guide in its 465 documentation pages; its blog discusses 140 and 1600 series in general | Documented: 140-series through Vobiz after DLT registration on the TATA Teleservices portal; 160-series through Plivo |
| Bring your own telephony | Pricing page lists it for Enterprise; docs document SIP trunk linking without naming a plan | Twilio, Plivo, Exotel, Vobiz or your own SIP trunk |
| Calling hours | Batch calling-hours fields are stored but “not enforced by the scheduler today”; retries are moved into 10:00–21:00 local time | Recipient-timezone guardrail that reschedules out-of-window calls; off by default |
| Hindi and Hinglish | Hinglish Map; Soniox or Deepgram Flux with Hindi and English hints; primary plus up to three secondary languages | Hinglish named; mid-call auto-detection for English and ten Indian languages |
| Campaign tooling | Batch calls from CSV or XLSX, 0–4 retries, workflows with weekday waits, workspace DNC list with automatic opt-outs | Batch calls from CSV, now or scheduled, auto-retry up to 3 times, voicemail detection, queued overflow |
| Free start | ₹1,000 in free credits | $5 in free credits |
In one sentence: Dialnexa prices every line in rupees and Bolna documents the Indian number and calling-hours plumbing more fully, so the choice turns on whether your bottleneck is budgeting or compliance routing.
What each platform charges per minute, and what the rate includes
Dialnexa publishes three plans on its pricing page. Pay As You Go is ₹5 a minute with no minimum. Growth is ₹4.20 a minute with a “Minimum commitment: 1L per month · 6 months minimum”, which its FAQ describes as ₹1,00,000 a month “for roughly 24,000 billed minutes”, yet the same FAQ says “Growth can be cancelled with 30 days notice”, so ask which term binds. Enterprise is ₹2.5–₹3.5 a minute with a ₹5L monthly minimum. Two of Dialnexa’s own figures for Enterprise disagree: the plan card says “12 months contract” and the comparison table says a minimum term of “4 months”, so ask which applies.
The plan rate is not the whole price. Dialnexa says “the per-minute plan rate covers DialNexa’s orchestration layer”, and that LLM, voice, transcription and Plivo telephony “are each billed separately”. Its rate card (rendered by script, not in the HTML) lists them per plan. For the stack its documentation sets by default (GPT-4o mini, ElevenLabs Flash v2.5) plus the Soniox transcriber its Hinglish guide recommends, Pay As You Go adds ₹0.16 + ₹0.12 + ₹0.20 for transcription, model and voice, and ₹0.85 for an outbound Indian call. Enterprise provider rates are “Custom”. Its billing documentation adds an estimated 18% GST to each wallet recharge and says standard credits are valid for six months.
Bolna starts at “$0.06 per minute (about ₹5.52) on pay-as-you-go, with speech-to-text, the LLM and text-to-speech included when your agent uses the bundled models”, and the same answer goes on: “Telephony and the platform fee are added per minute.” Its pricing page script holds seven top-up tiers, from $15 for 250 minutes at 6¢ to $3,000 for 66,500 minutes (50,000 plus a 33% bonus) at 4.51¢. The fee itself appears in Bolna’s docs FAQ: “$0.02/min platform fee (plus provider charges)”. As at 8 November 2026, Bolna does not print a per-minute rate for Indian telephony on its pricing page or in the documentation we searched; its cost summary says telephony is “Charged per minute by the carrier” and varies by country and provider, and the agent editor shows a per-minute Telephony line.
Bolna’s bundle has a condition: the flat rate covers only its preferred models; on any other model, that component “is billed at variable, usage-based rates”. On the Basic plan, bringing your own key for even one of transcription, LLM or voice moves that call off the flat rate. Our guide to what bringing your own API key does to voice agent cost explains why that can raise a bill. Bolna’s Pilot plan, $500 for 12,000 minutes or $300 for 6,500, is non-refundable and allows 25 concurrent calls.
Worked monthly bill at 10,000, 50,000 and 200,000 minutes
Built only from the two vendors’ published rates as at 8 November 2026. Assumptions: the minutes are billed minutes after pulse rounding; one Indian number; Dialnexa on the default stack above; Bolna on preferred models with its published top-up tier and its docs FAQ platform fee; Bolna wallet minutes assumed to carry into the next month. GST is shown for Dialnexa only, because the Bolna pricing page and docs we read do not say how tax applies to wallet top-ups; neither ex-telephony row includes it. Dialnexa at 10,000 minutes is shown on Pay As You Go, because Growth’s ₹1,00,000 commitment would cost more.
| Line (₹ a month) | 10,000 minutes | 50,000 minutes | 200,000 minutes |
|---|---|---|---|
| Dialnexa | |||
| Plan used | Pay As You Go | Growth | Growth (Enterprise shown below) |
| Orchestration (₹5.00 / ₹4.20) | 50,000 | 2,10,000 | 8,40,000 |
| Soniox speech-to-text (₹0.16 / ₹0.14) | 1,600 | 7,000 | 28,000 |

| ElevenLabs Flash v2.5 (₹0.20 / ₹0.17) | 2,000 | 8,500 | 34,000 |
| Outbound India telephony (₹0.85 / ₹0.75) | 8,500 | 37,500 | 1,50,000 |
| Mobile DID, India (₹180 / ₹155) | 180 | 155 | 155 |
| Total before GST | 63,480 | 2,68,155 | 10,72,155 |
| Total ex-telephony | 54,980 | 2,30,655 | 9,22,155 |
| With 18% GST on recharge | 74,906 | 3,16,423 | 12,65,143 |
| Enterprise alternative | n/a | n/a | 5,00,000–7,00,000 orchestration plus a custom provider quote |
| Bolna | |||
| Top-up tier used | $600 tier, 5.22¢ | $3,000 tier, 4.51¢ | $3,000 tier, 4.51¢ (best published) |
| Speech, model and voice bundle | 48,024 | 2,07,460 | 8,29,840 |
| Platform fee ($0.02, docs FAQ) | 18,400 | 92,000 | 3,68,000 |
| Indian number ($5) | 460 | 460 | 460 |
| Total ex-telephony | 66,884 | 2,99,920 | 11,98,300 |
| Ex-telephony before the platform fee | 48,484 | 2,07,920 | 8,30,300 |
| Telephony | Not published as a rate; added at your carrier’s or Bolna’s per-minute rate | ||
The ex-telephony rows are the only like-for-like lines. With the $0.02 fee, Dialnexa’s published stack is cheaper at every volume shown: ₹54,980 against ₹66,884 at 10,000 minutes, ₹2,30,655 against ₹2,99,920 at 50,000, and ₹9,22,155 against ₹11,98,300 at 200,000. Bolna’s pricing page and call pricing breakdown both say a platform fee is added on top, and only its docs FAQ gives the amount. Before the fee, Bolna’s lines total ₹48,484, ₹2,07,920 and ₹8,30,300, so Bolna would be cheaper at all three volumes only if its fee were below about ₹0.45 (0.49¢) a minute. That makes the platform fee the one number to get in writing before you sign. At 200,000 minutes, Dialnexa’s Enterprise orchestration alone runs ₹5,00,000–₹7,00,000 before custom provider lines, and Bolna’s Enterprise pricing is “best-in-class pricing at committed volumes” with no figure published.
Outside both bills: Bolna’s 140-series route needs a ₹5,900 TATA Teleservices DLT registration, “even if your business is already registered on another operator’s DLT portal”, and Dialnexa’s Growth plan lists a six-month minimum, although its pricing FAQ also says Growth can be cancelled with 30 days’ notice.
Billing pulses: what a 20-second call really costs
Automated sales campaigns are full of short calls, and pulse rounding decides what each one bills. Bolna states that telephony is rounded to minutes and that the Pilot plan bills in 30-second pulses, but the pages we read, as at 8 November 2026, do not say how its flat per-minute rate is rounded on pay-as-you-go.
| Talk time | Dialnexa Pay As You Go (60 s) | Dialnexa Growth (30 s) | Bolna Pilot (30 s) |
|---|---|---|---|
| 20 seconds | 1 billed minute | 0.5 | 0.5 |
| 70 seconds | 2 | 1.5 | 1.5 |
| 150 seconds | 3 | 2.5 | 2.5 |
A 60-second pulse bills a 20-second call at double the 30-second rate, so convert talk time to billed minutes with your own call-length mix before using the bill above.
The 660-minute rule: check concurrency before price
TRAI’s preference schedule sets four time bands “default OFF for all customers”: 00:00–06:00, 06:00–08:00, 08:00–10:00 and 21:00–24:00, unless a customer switches them on. That leaves 10:00 to 21:00, which is 660 minutes a day. The 660-minute rule: each concurrent line can deliver at most 660 billed minutes a day of sales calls inside TRAI’s default window, so divide your monthly minutes by 660 times your calling days to get the fewest lines you need, and treat the answer as a floor, because lines idle while numbers ring.
| Monthly minutes | Minimum average lines, 26 calling days | Minimum average lines, 22 calling days | Dialnexa plan that covers it | Bolna plan that covers it |
|---|---|---|---|---|
| 10,000 | 0.58 | 0.69 | Pay As You Go (2 lines) | Paid account (from 10) |
| 50,000 | 2.91 | 3.44 | Growth (10); Pay As You Go’s 2 guaranteed lines fall short | Paid account (from 10) |
| 200,000 | 11.66 | 13.77 | Growth only with expansion beyond 10, or Enterprise | Paid account as concurrency scales with usage, or Enterprise |
Dialnexa’s concurrency documentation says it paces outbound Plivo requests at 3 calls per second on its India account, a shared limit rather than one per workspace, and that extra concurrency “does not remove a provider’s call-start rate limit”. Its platform page advertises “10,000+ concurrent” and “No concurrency cap”; plan against the pricing page’s per-plan numbers. Bolna’s concurrency tiers queue calls above your limit rather than reject them, splitting it evenly across providers with calls waiting.

Hindi, Hinglish and Indian-language support compared
Dialnexa’s site has 22 Indian-language pages, one of them for Hindi and Hinglish. Its multilingual and Hinglish guide recommends Soniox or Deepgram Flux for Hindi-English code switching, sends “en” and “hi” as language hints, and offers a Hinglish Map. An agent takes a primary language and up to three secondary languages, and the dashboard narrows the list to voices that support every language selected; some “unavailable languages are hidden”, so a language page is not proof of a voice.
Bolna’s supported-languages page lists 19 languages, 12 of them Indian (Hindi, Bengali, Assamese, Gujarati, Kannada, Malayalam, Marathi, Odia, Punjabi, Tamil, Telugu and Urdu), and says “each language also needs a transcriber and a voice that support it”. Mid-call auto-detection is “tuned for English and ten Indian languages”, which leaves out Assamese and Odia. Its home page names Hinglish. Test your second language on a real call on either. For a wider language grid across twelve platforms, see our comparison of agentic voice AI platforms for sales teams in India.
Indian numbers, 140-series routes and bring-your-own telephony
Bolna’s guide to 140- and 160-series numbers in India is the most complete answer either vendor publishes. Promotional calls run on 140-series numbers through Vobiz after Principal Entity registration on the TATA Teleservices DLT portal (certificate of incorporation, GST certificate, company PAN, director list and memorandum, and a director-signed letter of authorisation); service and transactional calls run on 160-series numbers provisioned through Plivo. Bolna connects Twilio, Plivo, Exotel, Vobiz or your own SIP trunk. One catch: its Indian-server guide requires Plivo for India processing, while its 140-series route is Vobiz, so ask whether the two combine.
Dialnexa sells Indian numbers through Plivo or Vobiz. Before KYC, its KYC and outbound readiness page says a batch on a non-SIP number “can only call the workspace owner’s registered phone number”, and Indian Plivo numbers also need a compliance ID that Dialnexa attaches. We could not find a 140-series provisioning guide in Dialnexa’s 465 documentation pages, as at 8 November 2026, although its blog describes the 140 and 1600 rules and its comparison pages say DLT template management is “Built into platform”. Ask for a test call from your registered 140-series number. Its pricing page lists bring-your-own-carrier under Enterprise, while its SIP trunking docs describe linking a trunk without naming a plan.
TRAI rules that apply to automated sales calls in India
These come from TRAI’s consolidated Telecom Commercial Communications Customer Preference Regulations, 2018 (TCCCPR) as at 21 May 2026, the 2025 Second Amendment and the Third Amendment Regulations, 2026. This is not legal advice; our page on whether AI cold calling is legal in India under TRAI rules covers consent and preferences in depth.
- Registration. Regulation 3(2): “No Sender, who is not registered with any Access Provider for the purpose of sending commercial communications under these regulations, shall make any commercial communication”; an unregistered sender’s telecom resources “may be put under suspension or may also be disconnected”.
- An AI agent is a robo-call. Regulation 2(bc) covers a call “using an artificial or prerecorded voice to interactively deliver a voice message without the involvement of human being on calling side for participating in the dialogue”. If a person on your side joins the dialogue, the third limb may no longer be met.
- Tell your operator now. Regulation 4 requires every sender to notify its originating access provider “in advance, about the use of Auto Dialer or Robo-Calls as well as the intended objective of such calls in writing”.
- Declare A2P calling next. The Third Amendment defines an application-to-person (A2P) call as one “initiated by an application, software system, or automated platform without direct human dialling”, and substitutes regulation 4: declare A2P use in advance with your calling line identity (CLI) ranges and any other details TRAI specifies, recorded on the DLT platform by your operator, or the calls “shall be treated as Unsolicited commercial communication”. That and the A2P charge below start sixty days after Gazette publication; the notification is dated 18 September 2026.
- Use the 140 series to sell. TRAI’s 2025 explanatory memorandum says “as on date, promotional call should be permitted through 140-series numbers only” and that DoT “has recently allotted 1600 series numbers for making transactional and service calls”.
- Default calling window. Bands before 10:00 and from 21:00 are “default OFF for all customers” unless the customer switches them on; customers can also block other bands and individual days.
- A2P termination charge. New regulation 35A lets the terminating operator charge the originating operator “upto Rs. 0.05 (five paisa only) per minute on per minute pulse basis for A2P calls”, with no charge on calls from 140xx, 1600xx, 1601xx or other series TRAI designates, calls made by or on the directions of TRAI, or calls by agencies it authorises. It is an operator-to-operator charge; it does not set what your carrier bills you.
- Enquiries. A “relationship” can rest on an inquiry the recipient made “in writing or through digital means” within the seven days before the communication, kept “in a verifiable form”, and not since ended by either party. Whether that overrides a block on promotions is not decided here.
The two platforms handle the window differently. Bolna’s calling guardrail is “off by default”, and its own regulation table lists India as “9:00 AM to 9:00 PM IST”, which starts inside the 08:00–10:00 band TRAI’s schedule sets default OFF; set 10:00 if you rely on defaults. Dialnexa’s FAQ says it handles TRAI compliance by “scrubbing numbers instantly before campaigns launch, enforcing compliant outbound hours”, but its batch API documentation says the batch calling-hours fields “are stored with the batch but are not enforced by the scheduler today”, while retries are moved into 10:00–21:00 local time where the number’s country has a known time zone. On Dialnexa, start first attempts inside the window yourself.
Who each platform is wrong for
Dialnexa is wrong for you if you need the platform to hold first-attempt batch calls to a calling window today, or if you need a documented 140-series provisioning path before you sign. If you want Growth’s 30-second pulse, note that below roughly 19,300 billed minutes a month its ₹1,00,000 commitment costs more than Pay As You Go on the same stack.
Bolna is wrong for you if you need one published all-in rupee rate before any call is placed: its Indian telephony rate is not printed, its platform fee amount appears only in its docs FAQ, and non-preferred models leave the flat rate. It is also wrong if you need India-only processing on Twilio, which its Indian-server guide says runs on US servers.
Either is the wrong tool if you only need speech models for your own pipeline; see our comparison of Sarvam AI and Gnani.ai speech models.
Frequently asked questions
Is Dialnexa or Bolna cheaper for automated sales calls in India?
On published rates as at 8 November 2026, Dialnexa’s stack excluding telephony costs less at 10,000, 50,000 and 200,000 minutes if Bolna’s $0.02 platform fee applies on top of its flat rate, as its docs FAQ states. Bolna’s pricing page says a platform fee is added but does not print the amount; Bolna would be cheaper at all three volumes only if that fee were below about ₹0.45 (0.49¢) a minute. Bolna does not publish an Indian telephony rate, so get it, and the fee, in writing. See Bolna’s pricing page.
What does Dialnexa’s ₹5 a minute include?
Dialnexa says its plan rate covers its orchestration layer only. Speech-to-text, the LLM, the voice and Plivo telephony are billed separately; on Pay As You Go its rate card lists ₹0.85 a minute for outbound Indian calls. Its pricing page also lists ₹180 a month for an Indian mobile number.
Does Bolna support 140-series numbers for telemarketing?
Yes. Bolna’s documentation says it provisions 140-series numbers through Vobiz after you register as a Principal Entity on the TATA Teleservices DLT portal, which carries a ₹5,900 fee even if you are registered with another operator. Read Bolna’s guide to 140- and 160-series numbers.
What hours can an AI agent make sales calls in India?
TRAI’s preference schedule sets 00:00–06:00, 06:00–08:00, 08:00–10:00 and 21:00–24:00 as “default OFF for all customers” unless a customer switches them on, which leaves 10:00 to 21:00. Customers can block other bands and days too. See TRAI’s consolidated TCCCPR, 2018.
Do I need DLT registration for AI cold calling in India?
Yes. Regulation 3(2) of the TCCCPR says no unregistered sender “shall make any commercial communication”. You also need a 140-series number for promotional calls and written notice to your operator that you use robo-calls, replaced by an A2P declaration once the Third Amendment commences. See TRAI’s 18 September 2026 press release.
How many calls can Dialnexa and Bolna run at once?
Dialnexa lists 2 concurrent calls on Pay As You Go, temporarily up to 20, and 10 on Growth, expandable to 40. Bolna gives trial accounts 2 and paid accounts 10 to start, scaling with monthly usage, with calls above the limit queued. See Bolna’s concurrency tiers.
Do Dialnexa and Bolna handle Hinglish?
Both say so on their own pages. Dialnexa offers a Hinglish Map and recommends Soniox or Deepgram Flux with Hindi and English hints. Bolna names Hinglish and auto-detects mid-call switches across English and ten Indian languages. See Dialnexa’s Hinglish guide.
