Write a brief in plain English. Drop in your knowledge base. The agent inherits a personality, a language, and the knowledge to answer real questions. ## Take 02 — Build a flow (0:45 — 1:30) The visual editor maps the conversation. Branch on intent, route to specialists, transfer to humans when needed. No code, no YAML — just a canvas. ## Take 03 — Launch a campaign (1:30 — 2:30) Upload a list. Set a schedule. Go. The system dials, respects DNC, retries intelligently, and reports live as the campaign runs. ## Take 04 — Read the results (2:30 — 3:45) Recordings, transcripts, summaries, sentiment, outcomes — all searchable. Export to your CRM or replay any call from the dashboard. *** # Book a Demo — 30 Minutes Live with the Team Source: https://halovoice.in/book-demo Schedule a 30-minute live demo via Cal.com.

The hard part is the dashboards, the lead manager, the compliance, and the audit trail. That's what we ship. **III. No code. No moats. No gatekeeping.** A non-technical operator should be able to deploy a production voice agent in under an hour. Self-serve from $349/month with the full feature set. **IV. Multi-provider, BYOK, no markup.** Powered by OpenAI, Cartesia, and Sarvam AI. Bring your own keys to any provider on any plan. Pay supplier rates plus the platform fee — no markup on minutes. *** # Security — Encryption, Compliance, Audit Source: https://halovoice.in/security ## In transit TLS 1.2+ on every connection. ## At rest AES-256 encryption. ## Authentication & authorization JWT-based authentication (access + refresh tokens).
