mylinehub/omnichannel-crm — reverse-engineered prompt

Build me a self hosted omnichannel CRM called MyLineHub. I want one agent desktop where a sales or support person can manage customer records, see activity history, and handle voice calls, SMS, WhatsApp, email, and web chat from one place.

Use the existing Java backend, Angular frontend, AI email service, and voice bridge parts in this repo. Include a web phone or autodialer area for calling, a simple shared inbox for email and chat, contact and lead management, agent login, automation hooks, basic analytics, and an admin area for settings and integrations.

Please make it something I can deploy on an Ubuntu server with PostgreSQL, Nginx, SSL, and clear start up steps. Don’t hardcode real secrets. Use placeholders and environment variables where needed. If any setup details are outdated, look up current docs online and adjust them.
