New to voice? If you are launching your first voice campaign, start with an Audio campaign. Audio campaigns are the simplest to configure — upload a pre-recorded message, select your contacts, and launch. Once you are comfortable with the workflow, explore TTS campaigns for dynamic content and IVR flows for interactive experiences.
Voice Feature Details
Voice Campaigns
Launch automated voice calling campaigns for notifications, alerts, reminders, and bulk outreach. Configure calling schedules, manage contact lists, and monitor results in real-time.
Use cases: Payment reminders, appointment confirmations, promotional announcements, emergency alerts, event invitations.
IVR Flow Builder
Design interactive voice response flows visually. Create menu trees, route calls, gather input, and connect to AI agents — all through a drag-and-drop interface without writing code.
Use cases: Customer support menus, lead qualification workflows, order status hotlines, multi-department routing, automated surveys.
Audio Library
Upload, organize, and manage audio files used in your voice campaigns and IVR flows. Includes a built-in TTS generator for creating voice content on the fly.
Use cases: Storing welcome greetings, holding promotional jingles, managing multi-language prompts, archiving call recordings for reference.
TTS Generator
Convert text to natural-sounding speech using AI-powered text-to-speech synthesis. Choose from multiple Indian languages and speaker voices.
Use cases: Dynamic content personalization (e.g., inserting a customer’s name), rapid prototyping of voice prompts, multi-language campaign variants, generating IVR menu prompts without recording studio time.
XML Template Builder
Create and manage VoxiXML scripts for advanced voice call logic. XML templates give you programmatic control over call flow for outbound campaigns across all providers.
Use cases: Complex call branching logic, integrating with external APIs mid-call, custom DTMF workflows that go beyond the IVR builder’s capabilities.

Call Logs
View detailed records of all voice calls made through the platform. Filter by date, status, campaign, or phone number. Export data for external analysis and billing reconciliation.
Use cases: Auditing call outcomes, analyzing campaign ROI, identifying bad numbers in contact lists, reconciling voice minute consumption against invoices.
Before You Begin
Before launching your first voice campaign, ensure you have the following prerequisites configured:
- Provider Configuration: At least one telephony provider (SignalWire, Plivo, or Indian Route) must be set up with valid SIP credentials in your Organization Settings.
- Caller ID: Configure at least one verified phone number to display as your caller ID. This is the number recipients see when you call.
- Voice Minutes Balance: Your plan includes a monthly allocation of voice minutes. Check your current balance under Billing and purchase additional minutes if needed.
- Audio Content: Prepare your audio files (greetings, IVR prompts, messages) or be ready to use the TTS Generator. Upload files to the Audio Library before creating campaigns.
- Contact List: Have your target phone numbers ready, either as a contact group already in the system or as a CSV file for upload (format: phone number, name, optional fields).
How Voice Calling Works
Voxvaani connects to telecom providers (SignalWire, Plivo, or Indian Route) to place calls. The system uses your configured SIP credentials or phone numbers to route calls through the selected provider network.
Voice Minute Consumption: Voice minutes are deducted upfront at campaign launch based on the count of contacts. Each contact consumes one voice minute regardless of whether the call connects, is answered, or fails. Calls that do not connect still consume the deducted voice minute. There is no refund for failed calls.
