Unlike traditional calling where one agent speaks to one customer, bulk voice calling delivers the same message to thousands or millions of customers simultaneously. Common examples include payment reminders, appointment notifications, and emergency alerts. The call connects, the message plays, and the call ends\u2014typically in 20-40 seconds.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1774347968954\"><strong class=\"schema-faq-question\">What is Voice Broadcasting?<\/strong> <p class=\"schema-faq-answer\">Voice broadcasting is the same as bulk voice calling. The terms are used interchangeably in the industry. Both refer to sending a pre-recorded or synthesized voice message to a large list of phone numbers quickly and at scale. Some providers prefer &#8220;voice broadcasting&#8221; for marketing purposes, while others use &#8220;bulk voice calling.&#8221; Functionally, they are identical.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1774350903248\"><strong class=\"schema-faq-question\">Is Bulk Voice Calling Legal in India?<\/strong> <p class=\"schema-faq-answer\">Yes, bulk voice calling is legal in India for transactional messages (payment reminders, appointment confirmations, OTP) and is regulated by TRAI. However, promotional bulk voice calls to customers who haven&#8217;t opted in are illegal and violate DND (Do Not Disturb) regulations. TRAI-compliant providers automatically filter numbers on the DND list before sending promotional campaigns. Non-compliance can result in penalties of \u20b950,000 to \u20b91,00,000 per violation.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1774351287488\"><strong class=\"schema-faq-question\">What is the Difference Between SMS and Voice Broadcasting?<\/strong> <p class=\"schema-faq-answer\">SMS (text messages) are limited to 160 characters and must be read. Voice broadcasting delivers a spoken message that plays when the call connects. Voice messages achieve 95%+ listen rates vs. 20-30% SMS open rates, making them more effective for time-sensitive information. However, voice calls cost more (\u20b90.25-0.50 per call vs. \u20b90.50-1.00 per SMS). Best practice: use voice for critical alerts and reminders, SMS for supplementary information.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1774351299439\"><strong class=\"schema-faq-question\">How Many Calls Can I Send Per Day?<\/strong> <p class=\"schema-faq-answer\">There is no daily limit on EnableX. You can send millions of calls per day depending on your account plan. However, carriers may rate-limit delivery if you send too many calls to the same area code simultaneously (to prevent spam). EnableX intelligently distributes calls across multiple carriers and time windows to optimize delivery while respecting carrier limits. For campaigns larger than 1M calls, contact our sales team to optimize delivery strategy.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1774351320943\"><strong class=\"schema-faq-question\">What is the Pricing?<\/strong> <p class=\"schema-faq-answer\">Pricing is volume-based, starting at \u20b90.50 per call for small volumes (1-10K calls\/month) and decreasing to \u20b90.25 per call for large volumes (500K+ calls\/month). Text-to-speech generation costs \u20b90.05 per minute of audio. No setup fees, no monthly minimums. You pay only for calls delivered. For 1 million calls per month, the cost is approximately \u20b9250,000-300,000 depending on volume tier.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1774515907304\"><strong class=\"schema-faq-question\">Can I Schedule Campaigns in Advance?<\/strong> <p class=\"schema-faq-answer\">Yes. You can upload your recipient list and message now, and schedule the campaign to deploy at a specific date and time. This is useful for time-sensitive campaigns (e.g., &#8220;remind customers at 6 PM the day before their appointment&#8221; or &#8220;send payment reminders at 8 AM on the 1st of each month&#8221;). You can also pause, resume, or cancel campaigns before they launch.<\/p> <\/div> <div class=\"schema-faq-section\" id=\"faq-question-1774515921775\"><strong class=\"schema-faq-question\">How Do I Track Results?<\/strong> <p class=\"schema-faq-answer\">EnableX provides a real-time dashboard showing calls delivered, answered, failed, no-answer, and cost. Export detailed call logs with timestamp, recipient number, duration, outcome, and cost per call. Webhook callbacks notify your system of each call&#8217;s status (answered, failed, etc.) in real-time. This data integrates with your CRM or analytics platform for deeper insights.<\/p> <\/div> <\/div>\n\n\n\n<h2 class=\"wp-block-heading\">Testimonials<\/h2>\n\n\n\n<div style=\"height:32px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<div class=\"row\" style=\"width:auto;\">\n  <div class=\"col-md-4 mb-4\">\n    <div class=\"p-3 bg-light h-100\" style=\"border-top: 4px solid #b4256a;border-radius: 8px;\">\n      <h5>RemitOnline<\/h5>\n      <p>&#8220;Using EnableX bulk voice calls, we reduced payment collection time by 40%.

However, voice calls cost more (\u20b90.25-0.50 per call vs. \u20b90.50-1.00 per SMS).
