TRAI & DLT Compliant 4.8/5 Rated
Your message, spoken in your customer's language

Bulk Voice Call Service Provider in India

Broadcast pre-recorded voice messages to lakhs of phones in minutes — in Odia, Hindi, English or any regional language — with press-1 responses, retry logic and call reports that show exactly who listened.

  • TRAI-DLT compliant
  • 230+ operator routes
  • 24x7 support

A voice call reaches people a text never will — customers who do not read SMS, rural audiences more comfortable listening than reading, and feature-phone users beyond the smartphone world. Guru SMS broadcasts your recorded message to thousands of numbers simultaneously, with delivery muscle built on 230+ operator connections.

Outbound dialer campaigns work for far more than promotions. Schools announce holidays in the principal's own voice, hospitals confirm appointments, finance companies remind about EMI dates, and political and social campaigns reach entire constituencies in the local dialect. A familiar voice carries trust that text cannot.

Every campaign comes with professional tooling: multi-language recording support, scheduled and staggered dialing, automatic retries for unanswered calls, DTMF capture so listeners can press 1 to respond, and detailed reports showing answered calls, listen duration and keypresses — your proof of real engagement.

FAQs — Voice Call Service

How many voice calls can I send in one campaign?

From a few hundred to several lakh calls per campaign. Our infrastructure dials thousands of numbers in parallel and staggers throughput to your chosen window, so even constituency-scale broadcasts finish on schedule.

Can I record the message in Odia or other regional languages?

Yes — any Indian language works. Upload your own recording or use our assistance for scripting and clean studio narration. Many clients run the same campaign in two or three languages split by audience region.

What is press-1 response and how do I get the data?

During the call, listeners press a key on their phone to respond — confirm attendance, show interest or request a callback. Every keypress is logged against the number and appears in your downloadable report in real time.

What happens to numbers that do not answer?

The system retries unanswered and busy numbers automatically at intervals you choose, typically two or three attempts. The final report separates answered, retried and unreachable numbers so you know your true reach.

How long can the voice message be?

Up to two minutes, though 30 to 45 seconds performs best — long enough for a clear message, short enough that listeners stay till the end. We help trim scripts for maximum listen-through.

Is bulk voice calling legal and compliant in India?

Yes, when run to opted-in audiences and within TRAI guidelines, which we enforce on every campaign. We advise on consent, calling hours and content so your brand stays fully compliant.

Can voice calls be triggered from my software automatically?

Yes. Our voice API triggers calls from your application — voice OTPs, order confirmations, emergency alerts — with the same delivery reporting as campaign broadcasts. Sample code is provided for quick integration.

How is a voice campaign priced?

Per connected call, in pulse-based slabs that drop with volume. Share your expected campaign size and we will send transparent pricing the same day — no setup fee, no rental, no hidden charges.
