A) N8N — Free, flexible, best automation

Architecture

n8n (self-host or cloud) orchestrates: lead fetch → dial trigger → call status handling → CRM

update → follow-ups

Telephony: Twilio / Exotel webhook

AI: OpenAI (for summary / dynamic questions) or Voiceflow webhook for richer convo

Ready-to-import flow (nodes)

1. Cron — runs every 2 minutes
2. Google Sheets (Read Range) — fetch leads where Status = Pending and AssignedTo =

unassigned

1. Set — pick next lead and mark DialAttempts (local variable)
2. HTTP Request (Twilio / Exotel API) — initiate outbound call (provide to , from ,

webhook_url )

1. Twilio: POST https://api.twilio.com/2010-04-01/Accounts/{AccountSid}/
2. Calls.json with Url pointing to your call handler endpoint
3. Wait for Webhook — capture call events (answered, completed, recording URL)
4. Function / OpenAI Node — generate call summary or suggested next-step
5. Google Sheets (Update Row) — write Status , LastContacted , CallRecordingURL ,

Notes

1. Decision (IF) — if Status = No Answer → set follow-up; if Interested → set
2. AssignedTo = SalesRep and notify via Email/Slack
3. HTTP Request (WhatsApp / SMS) — send follow-up message
