(One-Way Communication)
Simple pre-recorded message delivery
No interaction required from recipient
Use cases: Announcements, reminders, alerts, offers
Example:
'Your electricity bill is due on 15th Feb. Pay now to avoid penalty.'
VOICE OBD
(Interactive - Outbound Dialing)
Pre-recorded message + IVR keypress options
Collect customer responses/feedback
Use cases: Surveys, confirmations, lead qualification, appointment scheduling
Example:
'Press 1 to confirm appointment, Press 2 to reschedule, Press 9 to talk to agent.'
ConnexBetter Offers BOTH:
Simple voice broadcasting for announcements
Interactive Voice OBD service with IVR for surveys/confirmations
Mix both in same campaign (play message, then offer keypress options)

A bulk voice calling service provider is a platform that enables businesses to send pre-recorded voice messages or interactive calls to thousands of customers simultaneously. ConnexBetter provides cloud-based bulk voice calling solutions with advanced features like call scheduling, regional language support, and detailed analytics for campaigns. It's ideal for marketing, customer engagement, surveys, and emergency alerts.
Voice broadcasting is a one-way communication where a pre-recorded message is played to the recipient without any interaction. Voice OBD (Outbound Dialing) allows two-way interaction where customers can press keys (like press 1 to connect, press 2 for more info) and get connected to agents or trigger specific actions. ConnexBetter supports both voice broadcasting and interactive Voice OBD campaigns.
Bulk voice calling software works by uploading a contact list, recording or uploading a voice message, and scheduling the campaign. The system automatically dials all numbers, plays the message, and captures responses (if interactive). ConnexBetter's platform provides a web-based dashboard to manage campaigns, track delivery status, and download detailed reports with call durations and keypress data.
Bulk voice calling service typically costs between ?0.30 to ?0.40 per connected call in India. The price depends on the volume of calls, call duration, and routing preferences. ConnexBetter offers competitive pricing with no hidden charges. You only pay for successfully connected calls, not for busy, failed, or unreachable numbers. Volume discounts are available for high-volume campaigns.
