I want to deploy an AI-driven voice calling agent that can run our outbound and inbound sales conversations without human intervention. Its main job is to place sales calls that actively generate fresh leads, nurture warm ones, and circle back for timely follow-ups. The agent will speak with both brand-new prospects and our existing customer base, adapting the tone and script dynamically to each segment so conversations feel personal, not robotic. Key capabilities I’m after include: • Natural-sounding speech recognition and synthesis • Real-time sentiment analysis to steer the dialogue • Automatic CRM logging and call outcome tagging • Calendar, email, or SMS hand-offs when a human rep is required The finished solution should be fully configured, tested on sample lists, and ready for plug-and-play use with our VoIP system or a cloud telephony API such as Twilio. I’ll provide access to our current CRM and sales scripts; you handle the integration, training, and fine-tuning so the agent hits clear success metrics: accurate lead qualification, scheduled call-backs, and properly documented follow-up tasks. If you have experience building conversational AI for sales environments, especially with tools like Dialogflow, Amazon Connect, or similar frameworks, let’s talk.

I'd love to help you deploy an AI-driven voice calling agent that can efficiently run your outbound and inbound sales conversations. To achieve this, I'll focus on designing a robust workflow that ensures reliable retrieval quality, memory/logging, and modular orchestration. The hard part here is defining these reliable workflow boundaries, memory, and fallback behavior so the system keeps producing useful outputs over time. With my experience in developing AI systems, I've successfully delivered closely related work through Jarvis AI - Personal Automation Assistant. This project showcases my ability to orchestrate complex workflows, and I believe it maps well to the delivery risk in this job. For instance, Jarvis AI built a system that orchestrated 30+ automated workflows across scraping, system actions, and API-driven automation. To tackle this job, I propose the following short execution plan: designing modular workflow code, defining config or prompt structure, handling logging and fallback behavior, and providing a README. I'll also ensure that the first working loop covers the core sales conversation functionality.

Hey, I've built AI voice agents for sales and appointment booking using Vapi and ElevenLabs, integrated with CRMs and Twilio for outbound and inbound calling workflows. You can review my work here: https://www.freelancer.pk/u/UmairBuildsAI My plan for your project: Deploy an AI voice agent using Vapi for natural-sounding speech with ElevenLabs voices, OpenAI for dynamic conversation handling adapting tone and script per prospect segment. Outbound calling for fresh lead generation and warm lead nurturing, inbound handling for follow-ups. Real-time sentiment-aware dialogue steering via the LLM layer. Automatic CRM logging after each call with outcome tagging. Calendar, email, or SMS handoff triggers when a human rep is needed. Integrated with Twilio or your existing VoIP system. Configured and tested on sample lists before go-live. Recent similar work: AI voice receptionist for a medical provider using Vapi and GoHighLevel handling inbound calls and appointment booking in production. What CRM are you using and do you have your sales scripts ready to share? Happy to jump on a quick call to map out the full agent workflow. Best Regards, Umair

We’ve worked on AI automation projects involving LLM integrations, conversational workflows, CRM automations, API integrations, lead qualification logic, and outbound communication systems, so handling something at this level is familiar territory for our team. For a setup like this, the biggest focus would be natural conversation flow, real-time decision making during calls, proper CRM logging after every interaction, and making sure human handoff, callback scheduling, and follow-up actions happen automatically without breaking the customer journey. Integration with Twilio, cloud telephony APIs, CRM systems, email/SMS workflows, and testing across inbound + outbound call scenarios can all be handled as part of the build. This looks more like building a complete sales automation system rather than deploying a simple AI assistant, which is exactly where proper architecture matters first.

You want an autonomous voice agent that places outbound and inbound sales calls — generating fresh leads, nurturing warm ones, and circling back for timely follow-ups with no human in the loop. I build exactly this. I shipped an AI phone agent for a tier-1 bank handling 3,500 calls/day on Twilio + Gemini — account queries, card activation, disputes, and live human handoff, all at sub-second response. Same core engine your sales caller needs: real-time ASR -> intent -> LLM dialog -> TTS, with barge-in. How I'd approach yours: Asterisk/Twilio telephony -> streaming STT -> an LLM sales-script engine (lead qualification, objection handling, follow-up scheduling) -> natural TTS, with CRM logging and a callback queue. Portfolio: https://www.freelancer.com/u/ZohaibSathio. Which dialer/PBX are you on — raw Asterisk, or a hosted provider? — Zohaib, AI Engineer (Voice AI · Autonomous Agents · RAG)

Drawing from my broad experience in AI, machine learning, and cloud data engineering, your project aligns perfectly with my strengths and capabilities. As an AI/ML Engineer, I'm well-versed in developing and deploying intelligent models for various purposes, including the design of predictive and conversational AI applications like the one you need. In terms of voice interactions, I'm extensively trained to design and implement Natural Language Processing (NLP) models that offer natural-sounding speech recognition and synthesis—essential for your AI Sales Call Agent's effectiveness in generating leads through personal conversations. Additionally, such interactions require real-time sentiment analysis to tailor the agent's tone appropriately. My skills here bring great value. Understanding that a sales conversation still merits human intervention at times, I excel in building intelligent workflows that facilitate hand-offs and automate processes where possible. From your project description, this would involve managing calendar updates, email notifications, or SMS follow-ups—a feat I've accomplished seamlessly for previous clients using Twilio or similar platforms. And as an end-to-end problem solver, everything from CRM integration to testing on sample lists will be handled with diligence to ensure successful deployment and easy plug-and-play compatibility for your VoIP system or other telephony API.

Hi Boss, I’ve worked on AI voice and telephony integrations using Twilio and conversational AI frameworks, so this project is well aligned with what I do. I understand you need a fully automated AI calling agent that can handle both inbound and outbound sales calls, qualify leads, manage follow-ups, and integrate smoothly with your CRM and VoIP system while keeping conversations natural and human-like. Here’s how I would approach it: Build a real-time voice pipeline (speech-to-text + LLM + text-to-speech) Integrate Twilio (or your preferred VoIP) for inbound/outbound calling Add sentiment detection to adjust tone and responses dynamically Connect directly with your CRM for automatic logging and lead tagging Implement escalation flows (SMS/email/calendar handoff when needed) Test with sample call lists and optimize for lead qualification accuracy and conversion Before starting, I would like to clarify: Which CRM are you currently using (HubSpot, GoHighLevel, custom, etc.)? Do you already have call scripts or should I help design conversational flows? Expected call volume per day (to design scaling properly)? Once confirmed, I can build a working prototype first, then scale into a production-ready system with full integration and testing. Looking forward to working with you, Boss.
