IVR API for Automated Voice Call Workflows
An IVR API lets you build Interactive Voice Response call flows - menus, keypad input, routing logic - programmatically, so an inbound or outbound call can present options, collect a response and act on it automatically. Teleopedia supports Interactive Voice Response (IVR) flows as part of its Voice & OBD Calling capability.
This page focuses specifically on IVR: menu design, DTMF input, call routing, common workflows, and how it integrates alongside SMS and WhatsApp. For the broader voice calling picture, see Voice API.

What Is An IVR API?
An IVR (Interactive Voice Response) API is a programmable interface for building call flows that present a caller with options - typically by voice prompt - collect their response, and take an action based on it, all without a person handling the call manually at each step.

Programmable IVR vs Traditional IVR Systems
A traditional IVR is usually configured once through a phone system's own console, with limited flexibility to connect it to other business systems. A programmable IVR API lets you define, version and change flow logic through a dashboard or code, and connect each step to your own backend - checking an order status from your database mid-call, for example, rather than only playing static pre-recorded options.
IVR Menu Design & DTMF Input
A menu presents a small number of clear options, and the caller responds using DTMF (keypad) input - pressing a number key to make a choice. This is the core interaction model Interactive Voice Response flows are built on:
Menu Structure
Keep menus short and options clear - each level should offer only a handful of choices before routing further.
DTMF Input
Keypad presses are captured and passed to your business logic to determine the next step in the flow.
Call Routing, Department Routing & Agent Transfer
Routing a call to the right flow or destination is core to how IVR works - a caller's menu selection determines what happens next. Department-specific routing and transferring a call to a live agent are common capabilities in IVR platforms generally; confirm current support for your specific routing and transfer requirements with your account team rather than assuming a particular setup is available by default.
IVR Use Cases
Automated Notifications
One-way announcement calls for time-critical updates - a confirmed Teleopedia voice capability.
Customer Support
A menu that routes a caller toward the right support flow before any human involvement.
Payment-Related Workflows
Payment reminder or confirmation flows delivered by automated call.
Appointment Systems
Confirming or reminding about an appointment through an automated voice flow.
Lead Qualification
IVR is commonly used industry-wide for basic lead-qualification flows; confirm current support for this specific workflow with your account team.
Surveys
Simple keypad-response surveys are a common IVR use case industry-wide; confirm availability for your account.
Logistics
Delivery-window and delay notifications delivered as an automated voice announcement.

IVR API Integration & Architecture
IVR flows run on the same voice calling endpoint used for any outbound call - the flow ID you reference determines whether the call plays a simple one-way announcement or a full interactive menu:
POST /voice/calls
Authorization: Bearer YOUR_API_KEY
Content-Type: application/json
{
"to": "+919876543210",
"flow_id": "ivr_flow_support_menu",
"language": "en-IN"
}Call and flow-step status is reported back through the same webhook shape used across channels:
{
"message_id": "voice_5c81ab",
"channel": "voice",
"status": "delivered",
"timestamp": "2026-09-21T10:42:00Z"
}Security & Scalability
Security
Treat DTMF input tied to sensitive actions (like payment confirmation) and any call recordings as sensitive data, with access restricted accordingly, and keep your API key secure.
Scalability
IVR runs on the same voice infrastructure built for OBD campaigns at scale - confirm your account's concurrency limits with your account team before a large rollout.
IVR + AI Voice
Teleopedia supports multi-language voice bots that can read dynamic content back to a caller. Fuller conversational AI voice - natural-language understanding in place of menu/DTMF navigation - is a broader integration concept worth discussing with your account team for your specific use case, rather than something this page confirms as a standard feature.
For a fully conversational voice experience, check current availability directly with your account team - what's confirmed on this page is multi-language voice flows and DTMF-based IVR, not open-ended voice AI.
IVR + SMS Fallback
An unanswered or failed IVR call can be part of a broader routing plan where a business configures SMS as a subsequent channel for a given use case - business-defined, not automatic for every call. See SMS API and Omnichannel Messaging Fallback for how this routing works.
IVR + WhatsApp
IVR/Voice runs on the same account as WhatsApp Business API, so a business can design a journey where WhatsApp handles the ongoing conversation and voice/IVR is reserved for the most time-critical or verification-related steps. See Omnichannel Messaging Platform for the full picture.
IVR Pricing Considerations
IVR calls are priced within the same voice/telephony cost structure as other voice calls, plus platform charges - we don't publish a flat rate here since it depends on call volume, flow complexity and your plan. Talk to our team for a quote based on your actual usage.
IVR API FAQs
What is an IVR API?
An IVR API is a programmable interface for building Interactive Voice Response call flows - menus, keypad input handling and routing logic - that a caller experiences on an inbound or outbound call, controlled through code rather than a fixed phone-tree configuration.
How does IVR work?
An incoming or outgoing call connects to an IVR flow, which presents a menu, collects input (typically DTMF keypad presses), applies your business logic to that input, and then takes an action - playing information, routing to an agent, or calling another API.
Is Teleopedia's IVR different from a traditional IVR system?
Traditional IVR is usually configured once through a phone system's own console. A programmable IVR API lets you define and change flow logic through your dashboard or code, and connect it to your own backend systems and events.
Does Teleopedia support DTMF input?
Yes, DTMF (keypad) input handling is core to how Interactive Voice Response flows work - it's how a caller navigates a menu or provides a response during a call.
Can IVR route calls to different departments or agents?
Call routing to a specific flow or destination is core to IVR. Department-specific routing and live-agent transfer are common IVR capabilities industry-wide - confirm current support for your specific setup with your account team.
What are common IVR use cases?
Automated notifications, customer support menus, payment reminders, appointment confirmations, and industry-specific alerts in healthcare, banking and logistics - see the use cases on this page.
How do I integrate an IVR API?
IVR flows are triggered and managed through the same Voice API used for calling - your application calls the API with a recipient and a flow ID, and the configured IVR logic runs on that call, with status reported back via webhook.
Is there a separate IVR endpoint from the Voice API?
No - on Teleopedia, IVR flows run on the same voice calling infrastructure and endpoint used for outbound calls; the flow ID you reference determines whether the call plays a simple announcement or a full interactive menu.
How do I track IVR call status?
Call status is reported through the same webhook mechanism used across every channel on your account, so your application can track whether a call was placed, connected or completed a given flow step.
Can IVR calls fall back to SMS?
Yes, an unanswered or failed IVR call can be part of a broader fallback strategy where a business configures SMS as a subsequent channel for a given use case, rather than this happening automatically for every call.
Can IVR work alongside WhatsApp?
Yes, IVR/Voice runs on the same account as WhatsApp, RCS and SMS, so a business can design a communication flow where voice is one step - often the final, most urgent one - alongside messaging channels.
Does IVR support multiple languages?
Yes, multi-language voice bots are a supported Teleopedia capability, so an IVR flow can be delivered in the caller's preferred language.
Is AI voice available for IVR?
Multi-language voice bots that read dynamic content are supported. Broader conversational AI voice - natural language understanding instead of menu/DTMF navigation - should be treated as a general integration concept to discuss with your account team, not assumed as a documented feature on this page.
Is DLT registration required for IVR calls in India?
Yes, DLT-registered voice templates are required for compliant outbound calling to Indian numbers, the same framework that applies to Teleopedia's broader Voice & OBD capability.
How secure is an IVR integration?
Standard practices apply - store your API key securely, validate webhook payloads before trusting them, and treat any call recordings or collected input (like payment-related DTMF entries) as sensitive customer data.
Can IVR scale to handle high call volumes?
IVR runs on the same voice infrastructure built for OBD campaigns at scale - concurrency and throughput limits depend on your plan, so confirm current limits with your account team before a large rollout.
How is IVR pricing structured?
IVR calls are priced within the same voice/telephony cost structure as other voice calls, plus platform charges - we don't publish a flat rate here since it depends on call volume, flow complexity and your plan. Talk to our team for a quote based on your actual usage.
