Automate phone answering — highlights from the r/n8n thread (April 27, 2026)

Major highlights

The top replies split into two camps: pragmatic integrations that treat n8n as the "workflow brain" and heavier, full-control stacks for realtime voice. Key recommendations and gotchas are below.

Top technical guidance (summary)

vapi.ai — recommended as the best n8n fit: webhook fires on call-start with {caller_id, transcript_so_far}. n8n responds with text and vapi speaks it back.

retellai — fine for voice-only, but gives less control; watch for a strict webhook JSON shape (you must echo tool_call_id or responses break).

Twilio + Deepgram + OpenAI Realtime — most control and complexity (more code), suited for teams that need full realtime pipelines.

Role for n8n — use it as the workflow brain only.…
