Hello, I can set up an AI Agent that researches leads, places scripted calls through the Atlas Call System, and runs end to end on GumLoop or n8n with clear logs and KPIs. Approach • Lead research: scrape or API enrich from approved sources, dedupe, validate contact numbers, and score fit. • AI Agent: LLM driven planner with a fixed call script and guardrails. Uses STT for live speech, TTS for responses, and strict slot filling to capture intent, interest, and next step. • Calling: integrate with Atlas Call System for dialing, call events, recordings, and dispositions. Retries and time windows respected. • Automation: GumLoop or n8n orchestrates research → call queue → call outcome → follow up email or task. Webhooks update a small status DB and your CRM if desired. • Compliance: consent checks, do not call lists, regional time rules, and masked PII in logs. • Monitoring: dashboard with attempts, connects, talk time, outcomes, bookings, and per step errors. Tech stack Node.js or Python FastAPI, Postgres, n8n or GumLoop, Atlas Call System APIs, OpenAI or comparable LLM, Whisper or cloud STT, cloud TTS. Deliverables • Running workflows with environment templates • Atlas integration, scripted call flows, and fallback paths • Admin dashboard and daily summary email • README, prompts, and test scenarios • Short handoff and support window Relevant work Automation and real time systems for Findnsecure, Esimfox, Shivaid, King Movers, and MayuriSharma.nl.
