I have an existing Python/Asterisk outbound autodialer running on a Debian 12 VPS. The application and dashboard are already built. I need an experienced Asterisk/ARI/AMI/Python developer to finish integrating the existing components, NOT rebuild the project from scratch. The system currently places outbound calls through a VMGate SIP/mobile gateway. Calling is working. We have also confirmed working two-way media/audio capture, AMI MixMonitor recording, DTMF transmission, and speech-to-text/transcription. The main remaining task is to connect the existing IVR state-machine ([login to view URL]) to the working live audio/transcription and DTMF system so the dialer can react to IVR prompts in real time rather than relying on fixed delays or post-call transcription. Important technical details: Debian 12 VPS Asterisk 22 Python application ARI for call/channel control AMI for MixMonitor and DTMF PJSIP/VMGate outbound trunk Existing web dashboard and CSV workflow Existing IVR state-machine Deepgram/live STT code already exists VMGate requires continuous RTP/silence to maintain the media path MixMonitor has been verified to capture valid IVR audio DTMF transmission has been verified I need someone who can inspect the existing code, preserve the parts that already work, and finish the real-time IVR call-control integration. Please do not propose rebuilding the entire application. I can provide the existing source code, server access, current configuration, logs, and a detailed technical handoff explaining what has already been tested and what remains.

Hello There! I’m Md Toriqul Islam, and I’m excited to partner with you. I have strong experience in Python, Asterisk, ARI/AMI, PJSIP, real-time audio processing, STT integrations, and telephony automation. I am skilled in Python, Asterisk 22, ARI, AMI, MixMonitor, DTMF, PJSIP, RTP, Deepgram/STT, and real-time call-state management. I understand you need the existing Python/Asterisk autodialer completed—not rebuilt. I can inspect the current codebase and connect the existing IVR state machine with the working live transcription and DTMF systems so calls can react to IVR prompts in real time. I have a few questions: 1) Which CRM are you currently using, and do you already have the required API/integration credentials? 2) Do you have a preferred WordPress builder such as Elementor, Divi, or Gutenberg? 3) How many landing pages are you planning to build after the pilot page? I’m ready to review the existing source code, logs, and configuration and start immediately. Looking forward to hearing from you. Best regards, Md Toriqul Islam

VMGate, MixMonitor, DTMF and Deepgram STT already independently verified means the expensive part is done, what's left is wiring, not a rebuild. The IVR state machine needs to react to two live streams instead of sleeping through fixed delays, AMI DTMF events on one side and whatever Deepgram streams back on the other. Neither needs the call flow touched, the state machine just needs to hold open subscriptions and fire transitions on event arrival instead of polling or waiting out a timer. My approach keeps the VMGate trunk, MixMonitor recording and DTMF transmission exactly as they are, and adds an event listener layer between AMI/ARI and the state machine so each state's wait becomes a callback bound to a digit or a transcription result, with the existing delay logic kept as a fallback timeout rather than the primary trigger. That limits the blast radius to the decision points, not the paths already working. 700 USD over 6 days, split so the trickiest wiring gets tested first: M1: AMI DTMF events wired in, digit driven transitions replacing fixed delays, $230, 1 day. M2: Deepgram streaming output wired in for transcript driven transitions, $250, 3 days. M3: End to end pass on a live call, tuning fallback timeouts and edge cases, $220, 2 days. That split is my read off the brief, the number that would move it is how much of the state machine already exposes hooks to bind into versus how much needs adding, which I'd know within an hour in the code.

Dear Client, I’m an experienced Python/backend developer with 10+ years of experience, including real-time systems, API integration, Linux servers, and communication workflows. I understand you need to finish the existing Asterisk 22 autodialer by connecting the current IVR state machine with live Deepgram STT, DTMF, and ARI/AMI call control, without rebuilding working components. I can inspect the existing code, preserve verified functionality, implement real-time IVR reactions, troubleshoot RTP/media behavior, and thoroughly test the complete call flow on Debian 12. My skills include Python, Asterisk, ARI/AMI, PJSIP, Linux, real-time APIs, STT, and debugging. Questions: 1. Is the existing Deepgram live STT code already receiving continuous RTP audio? 2. Can you provide the technical handoff and current logs? Best regards, Md Ruhul
