For most Indian businesses, reaching a customer has meant one thing for two decades: send a message and hope it lands. An order confirmation, a festive offer, a payment reminder - all one-way blasts, with little visibility into whether anyone read them, let alone replied. That model is now being replaced, and the evidence was on full display at India Mobile Congress (IMC) 2026 in New Delhi, where platforms built around two-way, AI-assisted customer conversations took centre stage.

Business Standard reported from the event on how companies such as Authkey.io and Airtel Business are combining SMS, WhatsApp, Rich Communication Services (RCS), voice and artificial intelligence into single platforms. These systems are designed not just to send messages, but to receive replies, qualify leads and automate routine conversations. For small and medium businesses, the shift matters because it changes what a messaging budget can do: from broadcasting offers into handling actual demand.

Why SMS Blasts Are Giving Way to Conversations

The old playbook was built around notifications. A business pushed out OTPs, delivery updates and promotional texts through application programming interfaces (APIs), and success was measured in delivery reports. The problem is that customers increasingly do not interact that way. They reply, ask follow-up questions and expect answers on the channel they already use.

Business Standard notes that the market has moved beyond sending messages: businesses now want to receive responses, manage conversations across channels and automate parts of customer interactions. That is exactly where AI is entering the communications stack. Instead of treating each channel as a separate pipe, platforms are being built as a single layer that carries the same customer conversation across SMS, WhatsApp and RCS.

India is not alone in this. Globally, communications platform companies such as Twilio and Sinch have expanded from basic messaging APIs into broader customer engagement platforms, with conversational AI and multi-channel support becoming part of their core offerings. The difference in India is the channel mix: WhatsApp's enormous user base, fast-growing RCS adoption and heavy use of digital advertising are pushing businesses toward platforms that can bring these channels together.

What CPaaS Actually Means for a Small Business

Communications Platform as a Service (CPaaS) allows a business to plug communication services - SMS, WhatsApp, voice, email and RCS - into its own applications and workflows through APIs. Instead of building and maintaining separate infrastructure for every channel, the business manages all of them through one provider and one dashboard.

For a small business, the practical effect is simple: one system to send, receive and track customer conversations, no matter which app the customer prefers. A shop can trigger a WhatsApp order update, receive a reply about delivery timing, route it to a support ticket and log the outcome, without switching between five tools.

Authkey.io: AI as the First Responder

One of the companies showcasing this approach at IMC 2026 was Authkey.io, an India-based communications platform that puts messaging, customer conversations and AI-led automation on a single system. Its founder, Ashish Jha, described the design as two-way from the ground up: "We have built an ecosystem where businesses can send and receive messages. So this is a two-way communication with AI handling your responses."

The platform is built to work with the way Indian businesses already advertise. For companies running Facebook and Instagram ad campaigns, the AI bot qualifies the leads those campaigns generate. Businesses load their frequently asked questions and answers, and the bot responds to enquiries based on intent. This directly attacks a familiar problem for small teams: a flood of enquiries where only a fraction are genuine buyers.

Jha's example is telling. A business might receive 100 leads, of which only 20 are relevant. "So now the business has to focus only on the productive part, not on filtering leads like contacting a junk lead, spam lead, leads which are not relevant to their business," he said. The platform can also raise support tickets and schedule appointments, and multiple teams and human agents can work inside what Jha calls an "entire team inbox."

Authkey is also building a custom AI layer that learns from a business's own data. Queries the bot cannot answer are flagged as "missed queries," shown to the business, and the answers added by the business feed back into the system. On the security side, the company says its platform is VAPT-certified, allows customers to hide their data from download or viewing, and masks mobile numbers so only the first five digits remain visible.

There is also a practical onboarding point that Jha raised: businesses testing an OTP or API service often wait two or three days to get started. He sees that delay as a real barrier, and speed of onboarding as part of the product battle.

Airtel IQ Gateway: One Control Plane for Every Channel

The telecom side is converging on the same idea. Airtel Business launched Airtel IQ Gateway on October 5, positioning it as India's first telco-grade business communications platform. It consolidates SMS, WhatsApp, RCS, business voice and number verification onto a single control plane, and it is designed to be compliant with India's Digital Personal Data Protection (DPDP) rules.

The platform attacks a costly problem: businesses juggle multiple vendors with limited visibility into whether their messages actually reach customers, while automated bots inflate bills through fraudulent international OTP traffic, a practice known as SMS pumping. Against that, Airtel IQ Gateway adds automated vendor failover, native DLT template integration and intelligent multi-channel routing, with real-time analytics and delivery reporting on one dashboard.

Two embedded security features stand out. Airtel IQ Verify scores fraud risk by evaluating network, device and usage signals to block fraudulent account creation, account takeovers and artificial traffic spikes. Silent Authentication confirms that the mobile number a user enters matches the active SIM in the device, reducing dependence on OTP-based logins and cutting exposure to SIM-swap attacks and social engineering.

Sharat Sinha, CEO of Airtel Business, framed the launch around trust: "With IQ Gateway, we are extending this proven expertise to enterprises, enabling them to build brand trust while ensuring every customer conversation is safe, authenticated and resilient." The platform can run on an enterprise's premises or as a cloud-hosted service, and it was trialled with select banks and financial institutions before its nationwide rollout. Airtel is showcasing it at IMC 2026, targeting sectors from banking and government to e-commerce and logistics.

The Numbers Behind the Shift

The data backs the direction of travel. Infobip's 2026 messaging report found that RCS interactions in India grew 70 per cent, while WhatsApp interactions grew 20 per cent. Infobip's own platform data paints an even sharper picture: RCS interactions in India rose 108 per cent between the first half of 2025 and the first half of 2026. Juniper Research forecasts that global RCS business messages will exceed 485 billion by 2030, up from 125 billion in 2026.

Infobip launched its RCS BusinessOS for mobile operators on October 7, timed to a stretch of the year when Indian messaging volumes peak. Harsha Solanki, VP and GM Asia at Infobip, put the moment plainly: "Enterprise communication in the region has reached an inflection point where reach alone is no longer enough. Brands in banking, ecommerce and consumer services want trusted, interactive interactions, and the approaching festive season will push messaging traffic to record levels."

Across BFSI, retail and quick commerce, the company says brands are moving beyond basic OTP notifications and transactional alerts toward verified, branded conversational threads - the same pivot that smaller businesses are beginning to face with their own customers.

What This Means for Your Business

  • Treat messages as conversations, not broadcasts. If your messages end at the delivery report, you are leaving replies - and sales - on the table. Accept that the value is in what happens after the customer responds.
  • Let AI handle the first pass. The 100-leads-to-20-relevant example is the everyday reality of digital advertising. Filtering junk enquiries is repetitive, learns well and is where a small team loses the most hours.
  • Follow your customer's channel. WhatsApp, RCS and SMS are not competing standards; they are routes to the same customer relationship. Track engagement and switch channels when one is not working.
  • Check security and compliance before you sign up. DPDP-compliant platforms, masked customer data and fraud protection against OTP pumping are now table stakes, not premium features.
  • Ask about onboarding time. If setting up an OTP or API service takes days, that delay is a cost. Quick-start APIs are part of the pitch for a reason.
  • Start small this festive season. Pick one channel done well, load your FAQs, watch which replies convert - and measure responses, not just messages sent.

The Road Ahead

The through-line at IMC 2026 was consistent: from sending a message to managing a conversation. For Indian businesses, that transition is taking place alongside rapid WhatsApp and RCS adoption and rising digital ad spends, giving communications platforms a much larger role in how customers are won and kept. The tools once available only to large enterprises - unified messaging, AI lead qualification, network-grade fraud protection - are now packaged for businesses of every size. The businesses that move first will not just send better messages; they will answer faster, filter smarter and sell more.
