What is Voice OBD?
What is Voice OBD?
Send automated voice calls to thousands of customers using recorded audio or text-to-speech. Use Voice OBD for promotions, reminders, alerts, surveys, payment notifications and customer engagement.
OBD stands for Outbound Dialing. Voice OBD is an automated calling service that dials a list of phone numbers and plays a pre-recorded or text-to-speech message when the call connects.
Instead of an agent dialling each customer manually, the system initiates the calls automatically in the background. Recipients hear your message, and where you configure it, they can respond by pressing keys on their keypad or by being connected to an agent.
Unlike an inbound call centre or an IVR number customers dial themselves, Voice OBD is campaign-based and outbound — your business starts the conversation, at scale, on a schedule you control.
◈
Automated or agent-assisted
Calls are placed automatically by the system. You can keep campaigns fully automated, or hand off connected calls to your agents when a live conversation is needed.
◈
One-way or interactive
Messages can be one-way announcements, or interactive with keypad (DTMF) options so recipients can confirm, reschedule or respond to surveys.
◈
Bulk and scheduled
Upload a contact list, choose a date and time, set retry rules, and let the system work through the campaign without manual effort.
◈
Reported and trackable
Every call returns a status — answered, busy, failed, no answer — so you can measure results and refine future campaigns.
How Voice OBD compares to other calling services.
Voice OBD is often confused with IVR, voice broadcasting, auto dialers and call centres. They are related — but they are not the same thing.
Service
What it does
Direction
Key difference from Voice OBD
Voice OBD
Automated outbound voice campaigns to a contact list — reminders, alerts, promotions, surveys.
Outbound
—
Voice Broadcasting
Plays the same recorded message to a large audience at once.
Outbound
A subset of Voice OBD — broadcasting is typically one-way with no response options.
Auto Dialer
Automatically dials numbers, often connecting answered calls to agents.
Outbound
A dialer is a calling engine; Voice OBD is a complete campaign workflow around that engine.
IVR
Callers navigate a menu (press 1 for sales, press 2 for support) when they call you.
Mostly inbound
IVR waits for the customer to call you; Voice OBD calls the customer. They can be combined.
Call Center
Agents handle inbound or outbound conversations for support and sales.
Both
Agent-led and live; Voice OBD is automated with optional agent handoff.
Transactional Voice Call
Service-related calls such as OTPs, confirmations and status updates.
Outbound
A category of Voice OBD focused on service (not promotional) communication.
Voice OTP
Reads a one-time password aloud for authentication.
Outbound
A specific high-priority transactional use of Voice OBD.
Automated
Calls are placed by the system on a schedule — no agent on the line required.
One-wayor Interactive
Choose simple announcements, or enable keypad responses and agent handoff.
Features
Everything you need to run a complete voice campaign.
Upload contacts, craft your message, schedule the campaign and measure the results — all from one dashboard.
◈
Bulk Voice Calling
Send thousands of automated outbound calls from a single campaign without agents dialling manually.
◈
Recorded Audio or TTS
Upload a pre-recorded message or use text-to-speech to convert written text into a natural voice instantly.
◈
Multilingual Messages
Reach customers in the language they understand best — including Hindi and other supported Indian languages.
◈
Dynamic Personalization
Insert customer names, amounts and dates into each call so every message sounds individual, not broadcast.
◈
Caller ID (CLI)
Choose the number customers see as your caller ID to build trust and improve answer rates.
◈
Smart Scheduling
Schedule campaigns for specific dates and windows, so calls land at the right time — not after business hours.
◈
Retry & Failover Rules
Set retries for busy lines and missed calls, so a single dropped connection doesn't lose the customer.
◈
DND Scrubbing
Screen numbers against Do-Not-Disturb lists before dialling, keeping campaigns compliant and reputation safe.
◈
Call Status Reports
See answered, no-answer, busy, failed and DND counts per campaign, with full call records to export.
◈
DTMF & IVR Responses
Add keypad options — press 1 to confirm, 2 to reschedule — and capture every response automatically.
◈
API & Webhooks
Trigger calls from your own software and receive call results in real time via API or webhook.
◈
CSV Upload & Segmentation
Import contact lists as CSV and split audiences by group or response so you can target precisely.
Voice OBD pairs naturally with an IVR flow — for example, the automated call delivers the message, then hands the recipient to your IVR menu or a live agent for a follow-up.
Voice OBD vs IVR
Voice OBD vs IVR — what's the difference?
Voice OBD and IVR are often used together, but they solve different problems. Here is how they compare.
Voice OBD
IVR
Direction
Outbound — the system calls your customers.
Inbound — customers call you and navigate a menu.
Primary use
Bulk announcements, reminders, alerts, surveys and follow-ups.
Self-service: support, order status, appointments, routing to the right team.
Initiation
Your business starts the call on a schedule.
Customer initiates by dialling your number.
Interaction
Optional — keypad responses, agent handoff, or one-way.
Always interactive — a menu of keypad options.
Typical campaign size
Hundreds to thousands of calls at once.
One call at a time, as customers call in.

Reaching a large list fast with the same message.
Deflecting routine queries away from your team.

Talk to our team — we'll map your use case to the right setup.
SMS is great for short, silent notifications. Voice OBD earns its place when a message needs to be heard, explained, or answered.
◈
Customers don't read SMS
Promotional messages often go unread or get filtered. A voice call that actually rings is harder to ignore.
◈
Important information needs explaining
Appointment details, payment instructions and service changes are communicated far more clearly in a spoken message.
◈
Regional-language communication matters
Customers who struggle with written English understand a voice call in their own language far better than a text they can't read.
◈
You need keypad responses
Only voice lets customers answer on the spot — press 1 to confirm, press 2 to reschedule — and feeds those responses straight back to you.
◈
You want a more direct channel
For urgent alerts like payment failures or security notices, a call delivers the message with the urgency it deserves.
◈
Voice fits the senior audience
Older customers — common in healthcare and finance — respond far more readily to a human voice than a text message.
SMS and Voice OBD work best together — for example, send an SMS confirmation, then follow up with a voice reminder a day before the appointment. We offer both channels, so you can build the right mix.
Channel Comparison
Voice OBD vs WhatsApp vs SMS.
Each channel has its strengths. Here's a quick guide to choosing the right one — we offer all of them, so you can pick the best fit per message.
Channel
Best for
SMS
Short alerts and notifications — OTPs, one-line updates and confirmations that need no explanation.
WhatsApp
Rich conversations and media — images, documents, buttons and two-way chat with the customer.
Voice OBD
Automated voice communication — reminders, payment alerts and announcements that need to be heard or answered.
IVR
Interactive customer support — self-service menus for queries, order status and routing to the right team.
RCS
Rich SMS-style messaging with buttons and media, where supported by the recipient's device and operator.
Ask the recipient to respond using keypad options or agent handoff, turning the call into a mini-conversation.
Examples: "Press 1 to confirm your appointment, press 2 to reschedule."
04 — Survey
Survey & Feedback Calls
Collect ratings and answers at scale with a structured question flow and automatic response capture.
Examples: customer satisfaction (CSAT), feedback after service or delivery.
05 — Reminder
Reminder & Follow-up Calls
Keep appointments and dues on customers' radar without occupying your team's time.
Examples: appointment reminders, fee reminders, EMI due reminders, medicine refills.
06 — Alert
Emergency & Alert Calls
Reach people immediately with time-sensitive updates where a missed message has real consequences.
Examples: payment failure alerts, security alerts, service outage, urgent notices.
Each type carries different compliance requirements — for example, promotional calls and service (transactional) calls are treated differently under TRAI's rules. See the DLT & compliance section below.
Campaign Types
Promotional vs Transactional voice calls.
These two categories of outbound voice call are treated differently under Indian telecom rules — here's the difference.
Promotional
Promotional Voice Calls
Messages that promote or advertise a product, service or business. Because the recipient didn't request them, promotional calls face stricter rules — consent requirements, DND scrubbing, and DLT-approved headers and templates.
Service-related messages sent in connection with a transaction or a service the customer already uses — the recipient expects them. Transactional calls typically have lighter consent requirements, though the communication must genuinely be service-related.
Important: The classification of a call as promotional or transactional affects what consent you need and how the call must be routed. Mixing promotional content into a transactional message, or treating an unsolicited promotional call as transactional, can lead to complaints and regulatory action. Confirm the right classification for each campaign with your telecom provider before launch.

Englishहिंदी (Hindi)Other Indian languages*
*Available subject to provider TTS support and route capabilities. Confirm supported languages for your campaign before finalising the message. For a pre-recorded message, any language can be uploaded as audio.
Example — Appointment Reminder
"Hello Rahul, this is a reminder about your appointment tomorrow at 11 AM. Press 1 to confirm, press 2 to reschedule."English — Text-to-speech"नमस्ते राहुल, आपके कल सुबह 11 बजे अपॉइंटमेंट के बारे में यह एक रिमाइंडर है। पुष्टि करने के लिए 1 दबाएं, पुनर्निर्धारित करने के लिए 2 दबाएं।"हिंदी — Text-to-speech
The same campaign can even use language detection or per-contact language tags so each customer hears the message in their preferred language.
Customer Call Flow
What a Voice OBD call sounds like.
Here's an interactive reminder call, step by step, from dialling to the result landing back in your CRM.
1
01Call connects
The system dials Rahul on 98xxxxxx10. He answers on the third ring. Caller ID shows your registered number.

4
04Response captured
Rahul presses 1. The system records his response instantly and plays a confirmation: "Thank you. Your appointment is confirmed."
5
05Result synced
The call result — answered, confirmed, duration — is pushed to your CRM or dashboard in real time for follow-up and reporting.
Calls that are unanswered, busy or unreachable follow your retry rules — for example, up to 2 retries at a fixed interval, before being marked accordingly in the report.

A short guide to Distributed Ledger Technology (DLT) registration and why it matters for voice calling in India.
DLT is the system India's telecom operators use to manage business communications. Under the Telecom Commercial Communications Customer Preference Regulations (TCCCPR), businesses sending promotional communications — including voice calls — are required to register on the DLT platform and route their traffic through registered headers and templates. The system is designed to trace the sender and reduce spam and fraud.
◈Registration
Your business registers as an entity on the DLT platform of the relevant telecom operator, and each brand gets a verified identity.
◈Headers
Approved sender IDs (for messages) and caller IDs (for voice) that identify your brand on outgoing communications.
◈Consent & templates
Promotional content must use approved templates, and recipients must have consented to receive your communications.
◈DND / NCPR
National Do-Not-Call Registry (DND) numbers must be screened out of promotional campaigns unless consent applies.

OBD stands for Outbound Dialing. It refers to an automated system that dials a list of phone numbers and plays a pre-recorded or text-to-speech message when the call connects.
What is Voice OBD?
Voice OBD is an automated calling service. You upload a contact list and record a message, and the system calls customers for you to play that message. It is commonly used for appointment reminders, payment alerts, surveys, and announcements.
What is the difference between Voice OBD and IVR?
Voice OBD is outbound — your business calls the customer with a message. IVR is mostly inbound — customers call you and navigate a menu (press 1 for sales, press 2 for support). The two work well together: a Voice OBD call can deliver a message, then hand the customer into your IVR menu.
Can I upload my own voice recording?
Yes. You can upload your own recorded message in any language, or use our text-to-speech option to convert written text into a voice message.
Does Voice OBD support text-to-speech?
Yes. Type your message and it is converted into a spoken message automatically — useful when you need to change campaign content frequently without re-recording.
Which languages are supported?
English and Hindi are supported for text-to-speech, with additional Indian languages subject to provider TTS support and route capabilities. For pre-recorded audio, any language can be uploaded. Confirm supported languages for your campaign before finalising the message.
Can I personalize calls?
Yes. Use variables like {{name}}, {{amount}} or {{appointment_date}} in your message so each call sounds individual — "Hello Rahul, your payment of ₹4,500 is due tomorrow."
Can customers respond by pressing 1/2/3?
Yes. You can add keypad (DTMF) options — press 1 to confirm, press 2 to reschedule — and every response is captured automatically. Calls can also be handed to a live agent where required.
Can I schedule campaigns and set retries?
Yes. Choose the date, time and calling window for your campaign, and set retry rules so busy lines and missed calls get another attempt at a suitable time.
Can I integrate Voice OBD with my CRM?
Yes. Call outcomes can be pushed back to your CRM or internal systems through API and webhooks, so confirmations, opt-outs and responses stay in sync with your records.
Is API integration available?
Yes. Use our API to upload contacts, trigger calls and receive delivery status updates, or configure webhooks to receive campaign events automatically. See the API documentation for details.
How does OBD pricing work? Are unanswered calls or retries charged?
You pay per connected call, with rates starting at ₹0.25 (25 paise) per call and decreasing at higher volumes. No-answer, busy, unreachable and DND-screened numbers are reported and typically not charged as connected calls — retries are billed as separate attempts. Confirm your rate card for exact treatment.
Is DLT registration required? Can Voice OBD call DND numbers?
For most promotional voice campaigns, your business must be registered on the DLT platform with approved headers and templates. DND-registered numbers are screened out of promotional campaigns unless valid consent exists. We guide you through registration and setup — see the DLT section above for details.
What are the applicable calling hours?
Promotional calls are restricted to permitted hours under TRAI rules. Our platform enforces these windows so campaigns only run during allowed times, and you can set narrower windows per campaign if you prefer.
How long does campaign setup take?
For a straightforward campaign with a ready contact list and message, setup is usually done within a day. Campaigns requiring DLT registration, new headers or custom IVR flows take longer — we'll give you a clear timeline at onboarding.
What reports will I receive?
You get call status reports per campaign — answered, busy, failed, no answer and DND-screened counts — plus individual call records you can export. Keypad responses and agent-handoff events are included where your campaign uses them.
Is it TRAI/DLT compliant?
Voice OBD campaigns must follow the applicable TRAI / TCCCPR requirements — including DLT registration, sender identification, consent, content templates, DND scrubbing, and permitted calling time windows. We filter DND numbers, restrict calls to permitted hours, and guide you through registration and setup. Compliance is a shared responsibility: we provide the controls and guidance, while the final rules depend on your campaign type and current regulations.
How do I get started?
