AI Voice Calling Assistant

A fully autonomous outbound-calling pipeline: it reads your contacts, places real AI voice calls, analyses every conversation, logs it, and updates the CRM — with no human in the loop.

1. 1

   The workflow

   1 / 3

   

   A finished call → AI analysis of the transcript → logging and a follow-up notification.

2. 2

   The call analysis

   2 / 3

   

   The AI extracts the outcome, sentiment, a summary and the recommended next action.

3. 3

   The follow-up notification

   3 / 3

   

   The business is notified whenever a call-back is needed — nothing slips through.

How it works

The problem

Outbound calling — lead qualification, follow-ups, reminders — eats hours of repetitive dialing. Many calls go unanswered, reps forget to log outcomes, and CRM updates slip, so follow-ups are missed and the pipeline leaks.

The approach

1. 1

   A scheduled n8n workflow reads the contact list (Google Sheets) and loops through every contact, automatically skipping anyone already called — idempotent, so re-runs never double-dial.

2. 2

   For each contact it places a real outbound phone call through a voice-AI agent (Vapi) that holds a natural conversation toward a defined goal.

3. 3

   A wait step holds execution until the call ends, then the full transcript and metadata are pulled back via API.

4. 4

   An LLM analyses each transcript and extracts a structured result — outcome (interested / no-answer / voicemail / callback), sentiment, a summary, and the recommended next action.

5. 5

   Every call is logged to a database (Supabase) with transcript and analysis, the contact's status is auto-updated to 'Called', and the loop advances to the next contact — fully unattended.

Highlights

• Fully autonomous: reads contacts, calls, analyses, logs, updates the CRM, repeats — no human, no missed follow-ups.
• Idempotent by design: already-called contacts are skipped, so it's safe to re-run anytime.
• Structured, queryable outcomes (outcome + sentiment + next action) instead of unwritten call notes.
