Frequently asked questions
What is IVR call blasting?
IVR call blasting (voice broadcasting) automatically calls many phone numbers at once and plays a pre-recorded message. With IVR, the person who answers can press a key — for example to speak to an agent, confirm, or opt out.
What is call blasting used for?
Common uses are announcements, payment and appointment reminders, event invitations, alerts, surveys and promotional campaigns.
Do I need my own servers or phone lines?
No. The 3G Callnet call blasting service needs no infrastructure setup on your side and is pay-as-you-use.
Is call blasting legal in India?
Yes, when it follows TRAI's commercial communication rules. Promotional calls must respect the customer's DND (National Customer Preference Register) preferences and be sent through registered telecom channels. The service includes DNC list checking; confirm your campaign type with us before launch.
Can I run several campaigns at the same time?
Yes. You can program and run multiple campaigns simultaneously, each with its own message, list and schedule.
