Voice, answered
Is voice calling available in India?
Yes. Telinfy runs outbound voice and inbound IVR across Indian networks (Jio, Airtel, Vi) on DLT-aligned, compliant routes with HD audio. You get Indian virtual numbers, caller-ID presentation and per-campaign analytics from one account.
What can I use automated voice calls for?
Common use cases: OTP and verification calls, payment and EMI reminders, appointment confirmations, delivery and COD confirmation, alerts, and automated voice surveys with keypress responses. Each can be personalised per recipient with text-to-speech and routed through an IVR menu.
Is there a voice call API?
Yes. Telinfy’s REST voice API and webhooks let your CRM, app or backend place calls, launch IVR flows and pull delivery, duration and keypress data programmatically — so voice drops straight into the systems you already run.
Can I run both outbound voice and inbound IVR?
Yes, side by side from one account. Broadcast a pre-recorded or text-to-speech message to many numbers at once, and run multi-level IVR menus where callers press a key or speak to self-serve, leave responses or reach the right agent.
Do you offer a white-label or reseller voice program?
Yes. Agencies, SaaS platforms and resellers can offer voice and IVR (alongside WhatsApp, RCS and SMS) to their own clients under their own brand on Telinfy’s white-label program — your branding and pricing, our infrastructure and support.
Do I need to record the audio myself?
Not at all. Upload your own recordings, or generate polished audio instantly with our text-to-speech engine, which covers many Indian and international languages and natural-sounding voices.
How is voice calling priced in India?
Voice is billed per call/minute and varies by route and call type. Telinfy gives you transparent INR pricing and one dashboard to track spend — talk to us for a plan matched to your volume; we don’t publish placeholder numbers.
Can callers respond during a call?
Yes. With keypress (DTMF) capture, listeners can press a digit to confirm, opt in, rate a service or transfer to a live agent, and every response is logged for you to act on.
