Hello, I have over 7 years of experience in Python and have carefully reviewed the requirements for the AI-Powered Voice Calling Agent Development project. To achieve the desired outcomes, I propose using Python for backend development, integrating open-source LLM models for AI logic, and leveraging Asterisk/Freeswitch for telephony. The system will be designed to handle outbound calls with dynamic scripts and personalized details, while inbound calls will be managed using pre-trained knowledge and CRM data. Training materials will be uploaded for continuous learning, and a white-label admin panel will be created for client customization. The technology stack will include Python/Node.js for backend, open-source LLM models for AI, Asterisk/Freeswitch for telephony, React.js/Vue.js for the dashboard, and PostgreSQL/MySQL for the database. To optimize costs, low-cost SIP trunk providers will be integrated, and open-source AI models will be prioritized over paid APIs. I would like to discuss this project further in detail. Please connect with me for a chat to explore how we can proceed. Best regards.
