Top 5 auto dialer software for call centres

Top 5 auto dialer software for call centres in 2026

Call centre is one word for two very different operations. A floor of five to fifty agents dialing their own lists wants software that installs today and adds no per-minute bill. A floor of a hundred agents with inbound queues and predictive dialing wants telecom infrastructure. This ranking is ordered for the first kind and says plainly where the second kind takes over.

Which auto dialer software is best for a call centre?

RMDialer is the best auto dialer software for Indian outbound floors of roughly 5 to 50 seats, at ₹1,908 per user per year with real mobile caller ID, a telecalling CRM and no per-minute telephony. Exotel and Ozonetel take over above that, where predictive dialing and inbound queues matter.

    The right software for an Indian outbound floor up to about fifty seats: real mobile caller ID, the lead record on the call screen, per-agent reporting for the supervisor and no telephony bill underneath it.

    Best for
    Outbound floors of roughly 5 to 50 agents dialing their own lists.
    Price
    ₹1,908 per agent per year (₹159 a month); 3-month plan ₹747 per agent; $29 a year or $12 per 3 months outside India
    • Agents dial from their own SIM, so customers see a normal mobile they can call back
    • Per-agent call reports, talk time and outcomes live in the app and in the supervisor’s browser
    • Guided sessions point the whole floor at one list with no duplicate dials
    • Call recording supported, set up with the team during onboarding
    • Official Meta WhatsApp Business API follow-up fires when the call ends, varying by outcome
    • Runs in 40 languages on Android and iPhone, which suits floors staffed across states

    The catch: Outbound only: no inbound IVR menus, no ACD queues and no predictive dialing across dozens of concurrent seats. Above roughly fifty seats, or for any inbound routing, a cloud contact-centre platform is the correct purchase.

  1. 2

    Exotel

    India’s cloud telephony incumbent, and the right answer once a floor needs genuine contact-centre infrastructure.

    Best for
    Mid-market and enterprise floors running inbound and outbound together.
    Price
    Platform pricing quoted on request, plus per-minute telephony billed separately
    • Full CCaaS: IVR, queues, routing and central recording
    • Handles very high concurrent call volumes
    • Mature APIs and enterprise integrations

    The catch: Virtual-number caller ID, per-minute telephony on top of the platform fee, and a real implementation project before the first campaign.

  2. 3

    Ozonetel

    The predictive dialing specialist here, aimed at large outbound floors that measure agents on connected minutes.

    Best for
    Floors running predictive campaigns across dozens of concurrent seats.
    Price
    Quoted on request; telephony billed separately
    • True predictive dialing at scale
    • Deep workforce reporting and supervisor tooling
    • Established Indian enterprise presence

    The catch: Overbuilt for a floor of ten, and predictive pacing creates the connect pause customers notice, which costs answer rates on cold lists.

  3. 4

    Knowlarity

    A long-established cloud communications provider, strong on reliability and enterprise support.

    Best for
    Enterprises standardising voice across several locations.
    Price
    Enterprise quotes; telephony billed separately
    • Long operating history in India
    • Enterprise-grade SLAs and support
    • Broad voice product range beyond dialing

    The catch: Enterprise sales cycle and pricing, and the same virtual-number trade-off as every cloud platform here.

  4. 5

    JustCall

    Cloud calling built around CRM integrations, with AI transcription and call scoring shipped in 2026.

    Best for
    Floors whose system of record is HubSpot or Salesforce and must stay that way.
    Price
    Per-user plans published on their site, plus per-minute telephony
    • Deep native integrations with major cloud CRMs
    • AI transcription and call scoring
    • Local numbers across several countries

    The catch: Per-minute telephony compounds with volume, and Indian recipients see an unfamiliar number, which shows up in pick-up rates before it shows up in the software.

Method

How this ranking was decided

These criteria are specific to this list. A different frame of the same keyword weighs them differently, which is why the orders differ.

  1. 1

    Floor size is the first question, not the feature list

    Under about fifty outbound seats, caller ID and cost per seat decide the outcome. Above it, concurrency, predictive pacing and queue routing decide it. Entries are ranked for the first case and described honestly for the second.

  2. 2

    What the customer sees when the phone rings

    Indian pick-up rates fall sharply on unfamiliar numbers and telecom spam labelling makes it worse. SIM-based software dials from a real mobile; every cloud platform here shows a virtual number, which is the trade for scale.

  3. 3

    The real monthly bill, telephony included

    Cloud platform pricing is quoted on request and then telephony is billed per minute on top. A floor making 20,000 calls a month should price the minutes before comparing software fees at all.

  4. 4

    Time to the first campaign

    SIM-based software dials the same morning. Cloud platforms need a virtual number, KYC, an IVR flow and an onboarding call first, which is worth it at scale and wasted on a floor of eight.

Why it leads

Why RMDialer wins the small and mid-size floor

Most Indian "call centres" searching for auto dialer software are outbound floors of eight, fifteen or thirty agents working lists they already own. For that operation the decisive facts are not concurrency or pacing algorithms. They are that the customer sees a real mobile number and answers it, that the agent has the lead record on screen before hello, that the supervisor gets per-agent outcomes without collecting a register at seven in the evening, and that nobody is billed per minute on top of the software.

RMDialer is the auto dialer software that delivers all four at ₹1,908 per agent per year, with call recording set up during onboarding, official-API WhatsApp follow-up when the call ends, and a browser view for the supervisor included in the same plan. A thirty-seat floor pays about ₹57,000 a year in software, with no telephony line underneath it, and dials the morning it installs.

Where this stops being true, said plainly: above roughly fifty seats, or the moment inbound queues, IVR menus, an ACD or predictive pacing enter the requirement, RMDialer is the wrong purchase and Exotel or Ozonetel is the right one. Buying a SIM-based app for an inbound contact-centre problem fails regardless of price, and no discount fixes it.

Reviews

What users say about the RMDialer auto dialer software

  • “Twenty-two agents, and the number on the customer’s screen is a real mobile. That single thing moved our connect rate more than any feature in the auto dialer software we ran before RMDialer.”

    Sudhir Rane

    Floor manager, outbound call centre, Pune

  • “We kept our cloud platform for the inbound line and moved the outbound floor to RMDialer. Honest split: the auto dialer software does the calling and the follow-ups, and we stopped paying per minute for the half of the work that never needed a queue.”

    Anjali Fernandes

    Operations head, insurance renewals BPO, Vasco

  • “I used to build the agent report myself every evening. With RMDialer the per-agent calls, talk time and outcomes are already there at six, which is the part of the auto dialer software I actually use daily.”

    Naveen Chintala

    Team lead, admissions calling floor, Hyderabad

  • “Thirty seats across three client campaigns. The RMDialer auto dialer software costs us about fifty-seven thousand for the year with no telephony line under it, which is less than one quarter cost us on the platform we left.”

    Shabana Ansari

    Owner, telecalling agency, Lucknow

  • “Our broadband drops most afternoons. The agents keep dialing because RMDialer places calls over the SIM, and the notes sync when the line comes back. Every cloud auto dialer software we tested simply stopped.”

    Gurpreet Sandhu

    Centre head, loan recovery floor, Jalandhar

Straight answer

When RMDialer is not the right pick

  • You run inbound queues, IVR menus or an ACD. Exotel and Knowlarity are built for that; RMDialer is outbound software.
  • You need predictive dialing across dozens of concurrent seats. Ozonetel is the specialist and RMDialer does not compete.
  • Your floor is above roughly fifty agents. At that size the concurrency and workforce tooling of a cloud platform earn their cost.
  • Every call must be recorded centrally to cloud storage under a compliance regime. The cloud platforms are built around that.

Frequently asked questions

Straight answers about choosing auto dialer software software.

Which auto dialer software is best for a call centre?

For Indian outbound floors of roughly 5 to 50 agents, RMDialer: real mobile caller ID, the lead record on the call screen, per-agent reporting and no per-minute telephony, at ₹1,908 per agent per year. Above that size, or with inbound queues, Exotel and Ozonetel are the right purchase.

Link to this answer
What is the difference between an auto dialer and a predictive dialer?

An auto dialer places the next call when the current one ends: one agent, one call, full context. A predictive dialer rings several numbers at once and connects whoever answers, which needs telephony infrastructure and creates the silent pause before hello that customers dislike.

Link to this answer
How does a dialer work in a call centre?

The software holds the list, decides who is called next and routes the connected call to a free agent with the customer record attached. SIM-based software does this through the phone in the agent’s hand; cloud platforms do it through rented numbers and a browser softphone.

Link to this answer
How many agents can RMDialer handle?

It is built for floors from a single caller up to roughly fifty agents, each dialing from their own handset with per-agent reporting rolled up for the supervisor. Beyond that, the concurrency and workforce tooling of a cloud contact-centre platform start to earn their cost.

Link to this answer
Does a small call centre need cloud telephony?

Usually not for outbound. Cloud telephony buys concurrency, IVR and queue routing, none of which a floor of fifteen dialing its own list uses. What it costs is a virtual number your customers do not recognise and a per-minute bill that scales with your activity.

Link to this answer
What does auto dialer software cost for a 30-seat floor?

On RMDialer, ₹1,908 per agent per year, so about ₹57,000 a year with nothing billed per minute. Cloud platforms quote their platform fee on request and add telephony per minute, so price the minutes for your real call volume before comparing the software fees.

Link to this answer
Can supervisors monitor agents live?

RMDialer gives supervisors per-agent calls, talk time, outcomes and follow-ups completed, live during the day in the app and on a full screen in the browser. It does not offer live call barge-in or whisper coaching, which are cloud contact-centre features.

Link to this answer
Do agents need company phones?

No. RMDialer installs on any Android 8+ phone, or on an iPhone with the build supplied on request, and dials from whichever SIM you choose, a company SIM or the agent’s own. Records stay in the company account either way, so an agent leaving does not take the pipeline with them.

Link to this answer
Is call recording included?

Call recording is supported and the RMDialer team sets it up with you during onboarding. Cloud platforms record centrally as part of the platform. On either, recording carries its own consent obligations in India, so tell customers when calls are recorded.

Link to this answer
What about DND and TRAI rules for outbound calling?

The software does not change your obligations. Respect DND registration for promotional calls, follow TRAI’s telemarketing rules if you are registered as a telemarketer, and keep records of consent. That applies identically to SIM-based and cloud dialing.

Link to this answer
Can we run campaigns across several teams?

Yes. Lists are assigned per agent or per team, guided sessions point a whole team at one list with no duplicate dials, and reporting separates the results by agent and by campaign, which is what an agency running several clients needs.

Link to this answer
Does it work when the internet drops?

SIM-based software keeps dialing, because the call goes over the mobile voice network rather than a data connection. In RMDialer notes and outcomes queue on the phone and sync when the connection returns. A cloud dialer stops entirely without data.

Link to this answer
How long does it take to get a floor running?

Most teams dial the same morning: install, import the list, name the outcomes, start the session. There is no virtual number to provision, no KYC to clear and no IVR to design, which is the part of a cloud rollout that takes weeks rather than hours.

Link to this answer
What is the honest case for a cloud platform over RMDialer?

Inbound routing, IVR menus, an ACD, predictive pacing, central recording at scale, or a floor above roughly fifty agents. If any of those are in your requirement, buy the cloud platform; a SIM-based app will not grow into them and the price difference will not matter.

Where do I get RMDialer?

Search RMDialer on Google Play for Android, or ask for the iPhone build at rmdialer.com, where it is supplied on request. There is a free 3-day trial with every feature on and no card, and onboarding is done with you on a live call rather than left to documentation.
