Hi Mahd, Hope you’re doing well. I’m looking to build an AI calling system and wanted to check if this is something you can help with. Requirement overview: The AI caller should call leads directly from an Excel sheet (uploaded list). It should use a flexible ChatGPT-based script (dynamic conversation, not a fixed IVR flow). The assistant should handle natural conversations (basic objections, FAQs, responses). Daily call volume requirement: **100–500 outbound calls per day. Call outcomes should be logged (Interested / Not Interested / Callback / No Answer). For this version, I do **not** require CRM or WhatsApp integration — only a robust AI calling system. Additionally, I’d like the system to include: 1. Proper error handling (hang-ups, silence detection, wrong numbers, retries). 2. Conversation state management during calls. 3. Basic reporting (call logs + summary of outcomes). 4. Deployment support and documentation for future scaling. I’m looking for a complete, deployment-ready setup — including telephony integration (Twilio/Exotel or similar), GPT integration, testing, and production deployment. Could you please share: 1. Have you built something similar before? 2. What tech stack would you recommend? 3. Estimated timeline? 4. Approximate budget range? Looking forward to your response. Best, Harshvardhan
