Hi, I’m Abhishek Rathore, a senior full-stack engineer. You need a production-ready AI voice receptionist that answers Vodafone SIM calls, speaks naturally, and logs structured call data into Google Sheets—I can build this end-to-end. ? Approach I’ll use a GSM gateway (GoIP/Hybertone) connected to an Asterisk server for SIM-based call handling. Real-time STT/TTS via Deepgram + ElevenLabs, and OpenAI for conversation logic with prompt-controlled flows. Backend (Node.js) will process calls and push structured data to Google Sheets via API. ✅ Core Features • Auto-answer incoming SIM calls via GSM gateway • Natural bilingual conversation (English + Arabic) • Dynamic question handling + intent capture • AI-generated summaries + lead classification • Google Sheets logging (structured, per-call row) • Call transfer to human via SIP routing ☁️ Reliability / Performance Stateless call handlers with webhook events ensure resilience. Fallback prompts if STT fails. Rate-limited API calls and retry logic for Sheets. Call recordings stored for audit/debug. ? Deliverables Fully deployed AI receptionist, GSM integration, conversation flows, Sheets automation, and documentation. ? Why Me Built similar voice + AI systems integrating telephony and real-time NLP pipelines. Do you already have a GSM gateway device in mind, or should I recommend one compatible with Qatar networks?

100% doable. Ai voice callers expert here. Have made and deployed 100+ AI voice callers and deployed across US, UK and India. What we can do in this is use Vodafone Qatar to give us a Sip connection after connecting number and we can use Vapi to serve as the host for logic and changings etc. (the prompt, languages) Feel free to message for any sort of demo. Would charge a bit high but the results would be second to none.

Hi there, This is a strong and very practical use case, but it needs to be built carefully—especially because SIM-based calling (GSM gateway) and real-time AI voice interaction must work reliably together. I have experience building AI voice workflows and integrating telephony with automation systems, and I can deliver a production-ready AI receptionist, not just a demo. AI Voice Layer - Speech-to-Text: Real-time transcription (Google STT or Whisper) AI Engine: OpenAI API for conversation handling Text-to-Speech: Natural voice (Google TTS or ElevenLabs for better quality) Data Capture & Automation - After each call, the system will automatically extract: Caller number, name, requirement, AI-generated summary, lead type, next action, timestamp Google Sheets Integration - Using API/webhooks, each call will create a structured entry in Google Sheets in real time. Data will be clean, readable, and ready for follow-up workflows. Let's connect to discuss and start work! Thanks Saurabh

Hi, This is Elias from Jagrati. This project is essentially a real-time AI voice agent connected to a local SIM (Vodafone Qatar) with full lead tracking and CRM automation, not just a chatbot prototype. My approach: 1. Telephony Layer (SIM-based calls) • GSM gateway integration (SIM routing for Vodafone Qatar) • Incoming call detection + auto-answer system • Call forwarding to human agent (fallback option) 2. AI Conversation Engine • OpenAI / GPT API for natural dialogue • Dynamic conversation flow (greeting → intent → follow-up questions) • Context memory during the call session • Structured response handling for data extraction 3. Voice System • Speech-to-Text (Whisper / Google STT / Vosk) • Text-to-Speech with natural voice (Azure / ElevenLabs / Google TTS) • Low-latency real-time conversation pipeline 4. Data Capture & Lead Logic After each call, system automatically logs: • Caller number • Name (collected during conversation) • Inquiry type • AI-generated call summary • Lead classification (Hot / Warm / Cold) • Next action suggestion • Timestamp 5. Google Sheets Integration • API-based real-time sync • One call = one structured row • Webhook triggers after call end • Clean CRM-style formatting for tracking Questions: Q1: Do you already have the GSM gateway hardware or should it be recommended? Q2: Expected daily call volume? Q3: Do you need Arabic + English support from day one? Ready to build a production-grade system. Best Regards, JP

Hi, As per my understanding: You want a production-ready AI voice receptionist that works with a Qatar Vodafone SIM via GSM gateway, answers calls naturally, understands queries, captures structured lead data, and logs everything into Google Sheets with options for human handoff. Implementation approach: I will build the system using a GSM gateway integrated with a telephony server (Asterisk/FreeSWITCH) to handle incoming SIM-based calls. Audio streams will be processed through STT (Whisper or similar) and TTS (natural voice engine) while an AI layer (OpenAI) manages conversation flow, intent detection, and response generation. A middleware service (Node.js/Python) will orchestrate call states, extract structured data (name, inquiry, lead type, next action), and push records to Google Sheets via API/webhooks. Fail-safes like timeout handling, fallback prompts, and human call transfer will be implemented. The system will be modular, secure, and optimized for real-time response. A few quick questions: 1. Do you already have a GSM gateway device, or should I recommend one? 2. Preferred language(s) for conversation (English, Arabic, bilingual)? 3. Do you want call recordings stored for review? 4. Should human transfer route to a specific number or a queue system?

Hello Sir, I am interested in your project. I have 7+ years of experience in telecom systems, VoIP, AI integrations, and automation, including building call handling systems with Asterisk/FreeSWITCH, GSM gateways, and API-based workflows. I can build a fully working AI voice receptionist system that connects with your Vodafone SIM via GSM Gateway, ensuring reliable incoming call handling. The system will automatically answer calls, interact with customers using natural conversation (via OpenAI or similar), and manage the full call flow professionally. I will integrate speech-to-text (STT) and natural text-to-speech (TTS) so the conversation feels smooth and human-like. The AI will greet callers, understand their needs, ask follow-up questions, and generate structured responses in real time. For your data capture requirement, I will ensure every call automatically logs key details such as caller number, name, inquiry, AI-generated summary, lead type, next action, and timestamp. This data will be sent directly to Google Sheets via API/webhooks, creating a clean and structured record for each call. I can also implement call transfer to a human agent when needed, ensuring no important lead is missed. The system will be stable, scalable, and production-ready—not just a demo—with proper documentation and handover. Please send me a message so we can discuss your setup and get started. Best regards, SoftNexus Technologies

I see you're looking for a real AI voice receptionist that works with a local SIM, not just a demo. I've built similar integrations before—like my full stack openings site that handles data capture and automation daily. Here's how I'd approach this: I'll set up a GSM gateway with your Vodafone SIM, integrate OpenAI for natural conversation, and use speech-to-text/text-to-speech for the voice part. The key is making sure every call logs into Google Sheets automatically with all those fields you mentioned. I can also add a transfer-to-human feature using Twilio or a simple call forwarding setup. I've worked with Node.js, APIs, and automation tools extensively—this is right in my wheelhouse. No fluff, just a working system. Are you free for a quick call to discuss the setup and timeline?

Hi there, I noticed you need an AI voice receptionist system that works with a Qatar local SIM card (Vodafone) to handle incoming business calls – automatically answering, speaking naturally, capturing customer requests, and storing call data (caller number, name, requirement, AI summary, lead type, next action, date/time) into Google Sheets via API/webhook, with optional human transfer. I have built similar telephony AI systems using GSM gateways, Twilio, or Asterisk, integrated with OpenAI for conversation, deepgram or Google STT, and ElevenLabs for natural TTS. I recently deployed an AI receptionist for a Dubai real estate client using a local SIM and GSM gateway, capturing lead data into Google Sheets and logging 50+ calls daily. For Qatar, I can use a compatible GSM gateway (e.g., GoIP or Dinstar) connected to your Vodafone SIM, route incoming calls to a Python/Node.js server, run STT->GPT->TTS, and push structured data to Google Sheets. Please share your GSM gateway model and expected call volume. Best regards, Mobasher Reza
