Outbound at scale

Batch campaigns - with India compliance when you need it

Upload contacts, set concurrency, and track every dial in real time. For India deployments: NCPR/DND scrubbing, TRAI calling-window enforcement, consent tags, and audit-ready logs - so promotional outreach doesn't fly blind.

  • NCPR/DND scrub before dial. Blocked numbers never enter the queue.
  • Calling-window enforcement (9 AM–9 PM IST). Timezone-aware scheduling for promotional outreach.
  • Audit-ready logs. Scrub results, dispositions, and agent actions timestamped.

TRAI rules vary by use case. Map workflows with your legal and compliance advisors.

Works with Twilio globally and Exotel / FreJun in India - or any SIP trunk you already run.

Live monitoring

Watch every call. Take over in one click.

Your team gets a real-time command center - follow live transcripts, jump in when a human is needed. Works for inbound, outbound, and batch campaigns.

  • Real-time call queue. See every active conversation across agents, numbers, and campaigns.
  • Live transcript stream. Follow the dialogue word-by-word - latency, language, and sentiment update as the call progresses.
  • Instant human takeover. One click pauses Varta and connects your agent with full conversation history in view.
  • Seamless handback. Return control to Varta when done - the agent picks up right where the human left off.
