Frequently Asked Questions
Common questions about voice broadcasting, IVR systems, and cloud voice API.
-
What is voice broadcasting and how does it work?
Voice broadcasting is a mass communication method that delivers pre-recorded or text-to-speech audio messages to thousands of phone numbers simultaneously through automated outbound calls. Businesses use it for appointment reminders, payment collection alerts, emergency notifications, surveys, and marketing campaigns. With SpringEdge's Voice Broadcasting API, you upload a contact list, configure your audio message, and launch the campaign — the platform handles dialling, retries, and reporting automatically.
-
Can I use text-to-speech for voice calls?
Yes, SpringEdge supports text-to-speech (TTS) in multiple languages including English, Hindi, and other Indian regional languages. Instead of pre-recording audio files, you simply pass your message text through the Voice API and the platform converts it to natural-sounding speech in real time. TTS is especially useful for dynamic messages like OTP read-outs, personalised account balance alerts, or order status updates where the content changes for every call.
-
What is IVR and how can I set it up with SpringEdge?
IVR (Interactive Voice Response) is a telephony system that interacts with callers through voice prompts and keypress (DTMF) inputs — for example, "Press 1 for sales, Press 2 for support." SpringEdge's Voice API lets you build multi-level IVR menus programmatically. You define the call flow through API parameters: set welcome messages, configure keypress options, route calls to different departments or phone numbers, and collect caller input.
-
Can I get virtual phone numbers from SpringEdge?
Yes, SpringEdge provides virtual phone numbers (also known as long codes) that can receive incoming calls and SMS. These numbers work without any physical SIM card or hardware. You can configure a callback URL on your virtual number to automatically forward incoming calls or messages to your application or server. Virtual numbers are ideal for two-way communication, customer support lines, lead generation campaigns, and missed call services. Contact our team to check availability for your preferred region.
-
How is voice broadcasting billed?
Voice broadcasting is billed on a per-pulse basis — you only pay for the actual call duration consumed. There are no monthly subscriptions or minimum commitment fees. Billing starts only when the call is answered, so unanswered and busy calls are not charged. Volume discounts are available as your usage scales up.
