Scalable AI Sales Voice Bot

I need a custom, human-sounding voice bot that can place and manage several thousand outbound calls at once, guiding each conversation toward our sales and marketing goals. The system has to converse naturally in both English and Spanish, detect intent accurately, and keep prospects engaged just as a trained agent would.

The call flow must plug straight into our CRM so every interaction is logged in real time and follow-up actions are triggered automatically. I am open to whichever cloud telephony stack—Twilio, SIP, WebRTC, or another—you feel delivers the concurrency we need, provided the final solution is stable, easily scalable, and cost-efficient.

For delivery, please include:
• A working, deployable application (source code + compiled build) capable of thousands of simultaneous calls
• Two language models (EN & ES) fine-tuned for sales conversations and objections
• CRM integration module with clear mapping of fields and webhooks
• Setup scripts and documentation so we can reproduce the deployment in our own cloud account
• A short demo showing the bot handling multiple live calls and updating the CRM in real time

If you already have experience combining speech-to-text, text-to-speech, and a dialog-management engine at this scale, let’s talk.
