Voice AI Agent Development using Retell AI -

@kareemmaize

Hi there To build a reliable Retell AI voice agent, the most critical part is designing real-time intent handling and call state management so the agent responds naturally while triggering the correct workflows. I’d approach this by structuring the system around clear call states (incoming → active → classified → follow-up), with intent detection mapped to actions like CRM updates, task creation, or transfer triggers. Retell AI would handle real-time voice interaction, while backend logic ensures outcomes like “Busy,” “Complaint,” or “Completed” are consistently classified and stored. This ensures your team gets structured, actionable data from every call—not just conversations. My process is simple: define call scenarios and intents first, build the Retell agent with response flows, integrate CRM and automation triggers, then test and refine real call behavior. I’m ready to start with call flow design and Retell setup, then deliver a working voice agent with CRM integration and automated follow-ups..

@bisaneema

Hello, I understand you're looking to build a Retell AI voice agent that can handle real-time conversations, detect intent accurately, and trigger workflows based on call outcomes. I can surely help with this as I’ve built similar AI voice systems integrated with CRMs and automation layers. I bring 6+ years of experience in AI and automation, working with Retell/VAPI, Twilio, n8n/Make, and CRM integrations to build conversational agents with intent detection, call routing, and automated follow-ups. A few quick questions: 1. Which CRM are you planning to integrate with? 2. Do you already have defined call scripts, or should I design them? 3. Should call recordings be stored in CRM or external storage (S3, etc.)? Happy to jump on a quick call to map this out and get your voice agent running smoothly. Best, Sudesh A

@ffulb

Your Retell AI voice agent needs real-time intent detection, CRM integration, and smart call routing with automated follow-ups. I'd build this using Retell AI's conversation engine connected to your GoHighLevel CRM, with custom webhooks handling the call outcome classification and triggering appropriate workflows for busy/DND/complaint scenarios. I built something similar - an AI travel planner with natural language processing that handles complex multi-step conversations and triggers different actions based on user intent. Also developed several automation pipelines that integrate with CRMs and handle real-time data processing. You can check out my work at ffulb.com. Ready to start once I take a look at your Retell AI setup and CRM endpoints to confirm the integration approach. Can you share your API credentials so I can assess the current configuration and map out the workflow triggers?

I’ve built real-time voice agents with intent detection, CRM integration, and call automation—this aligns closely with your requirements. Approach: Use **Retell AI as the core voice layer**, with a backend orchestrator (Node.js) to handle intent routing, workflows, and CRM sync. Core Implementation: * Real-time call handling via Retell AI (low latency, natural responses) * Intent detection layer (prompt + structured classification) * Dynamic conversation flow (adapts based on caller intent) Call Handling: * Warm + cold transfers to human agents * Call recording + secure storage * Outcome classification: * Busy / DND / Wrong Number / Complaint / Completed Automation: * Trigger workflows based on outcomes (tasks, notifications) * Auto-create/update contacts in CRM * Log full call activity + transcripts Architecture: * Retell AI (voice) * Node.js backend (logic + orchestration) * CRM integration (API/webhooks) * Optional queue system for reliability Deliverables: * Fully functional voice agent * Intent detection + classification system * CRM integration (contacts, logs, recordings) * Call transfer + recording setup * Automated follow-up workflows I focus on making voice agents feel fast, natural, and reliable—not robotic or delayed.

@jimkyleb

Hello, there, I hear you want a robust voice AI agent that handles real-time calls with Retell AI while syncing with your CRM and automating follow-ups. The core goal is a reliable system that understands caller intent instantly and adapts responses to drive outcomes, not just chatter. I understand the constraint: real-time intent detection must trigger the right actions and route to humans when needed, with all calls recorded and stored securely for compliance and coaching. My approach is to build a streaming capture and ASR pipeline fed into Retell AI, with a lightweight intent classifier and action orchestrator coordinating CRM taps and workflows. I’ll base decisions on a state machine that handles call context, transfers, and graceful fallbacks, mirroring what I’ve implemented in similar voice automation work. One key detail that affects reliability is how we manage edge cases like misrecognition or latency spikes. I would implement confidence thresholds, explicit retry prompts, and a resilient queuing fallback to maintain natural dialogue and consistent data capture. In practice I’d set up CRM contact creation, call logging, and activity trails, plus automated tasks and notifications triggered by outcomes such as Busy, DND, Wrong Number, Complaint, or Completed. The design will support warm and cold transfers, with secure recording storage. If you want, I can tailor the integration map for your CRM (GoHighLevel) and outline a phased plan with milestones, tests, and

?Hi C! This project is a great match for the kind of production-grade Voice AI systems I’ve been building and supporting long-term. ⭕I’ve worked extensively with Retell AI, ElevenLabs, and Deepgram, specifically on real-world calling agents that need controlled pacing, accurate data capture, and reliable success evaluation — especially in insurance and IVR-heavy environments. ⭕Live Voice AI Agent (Call-in Demo): +1 845 448 4423 A production voice agent using Retell+ ElevenLabs, tuned for deliberate pacing, silence handling, and structured call outcomes. ⭕Relevant Experience Example In a previous Retell deployment for an insurance verification agent, I implemented custom Success Evaluation logic that marked calls as Fail if policy numbers weren’t captured digit-by-digit or if call disposition wasn’t confirmed verbally. I also solved number pacing by splitting numeric strings into spaced tokens with enforced pauses — eliminating misreads like “nineteen twenty-five. Happy to work via monthly retainer or flexible hourly, depending on what fits your roadmap best. If you’re looking for someone who understands how Voice AI actually behaves in production, not just how it looks in docs — I’d be glad to talk next steps ? Best regards Jesse G.
