What is a bulk voice call service?
A bulk voice call service, also called voice broadcasting or OBD (outbound dialling), plays a recorded message to thousands of phone numbers at once. It is ideal when you need to reach people who do not read SMS, speak a regional language or need an urgent reminder.
Bulk SMS India also offers IVR services, where callers press keys to reach the right team or get information, missed call services for lead capture and polls, and OTP voice calls that read a code aloud. Every call is tracked with live reports showing answered calls, duration and key presses.

Frequently asked questions
Most common questions regarding our product
Are these live or automated calls?
Both. Bulk SMS India supports outbound automated calls as well as live transfers to agents, based on your campaign type.
Can I create custom call flows?
Yes. We help you design IVR flows, decision trees, and custom triggers — no coding required.
Can the system read customer-specific info (like names or OTPs)?
Absolutely. Using text-to-speech, we can dynamically include user names, order numbers, or OTPs in real-time calls.
What languages are supported?
Multiple. Hindi, English, Tamil, Telugu, Marathi, Bengali, and more — we support both regional and global language needs.
What is voice broadcasting?
Voice broadcasting sends a pre-recorded voice message to many phone numbers at the same time. It is also called a bulk voice call or OBD service.
Can I get an IVR number for my business?
Yes. We set up an IVR with your menu, recorded prompts and call routing, so callers reach the right team.
Are voice calls delivered to DND numbers?
Promotional voice calls follow the same TRAI preferences as promotional SMS. Transactional and service calls, such as reminders and OTPs, can reach customers who have a relationship with you.
