N8N Market Research Call Center

I’m building a call-center workflow in n8n so live agents can find appropriate candidate from our database, call, sms, email our contact list and gather insights for market research. Each call should capture feedback on job proposing and research automatization update database and pass information to physical agent

Here’s what I expect:

• Design an n8n workflow that pulls leads, assigns them to available agents, logs call results, and stores recordings.
- check available contact details, validate it existence (e-mail, whatsapp, phone, sms) decide the communication source
• Integrate a soft-phone or telephony API (Twilio, Plivo, Aircall, etc.) so agents place and receive calls inside the flow.
• Push every response, rating, and timestamp into our SQL CRM and surface them on a analytics board (Grafana or Metabase) or other
• Package everything in Docker, ready to deploy on an VPS, with a clear .env sample and install script.
• Provide concise documentation plus a short hand-off session so my in-house team can tweak the workflow later.

The goal is to collect data, database actualization and research the potential candidates and their readiness in new employment. Please rely on native n8n nodes wherever possible, commenting any custom JavaScript. If you’ve built similar setups, a quick screenshot or link will help me decide faster.
