Title: Build an AI Receptionist for Phone + WhatsApp with CRM & Calendar Integration Project description: I am looking for an experienced AI automation developer to build a 24/7 AI front-desk system for my business, consisting of two connected components: 1. AI Phone Receptionist The voice assistant should: Answer incoming calls 24/7 with a natural, professional voice. Understand callers in French and Moroccan Darija. Answer approved questions about services, prices, opening hours, and other basic information. Collect the caller's name, phone number, email, reason for contact, and notes. Handle appointment requests and book appointments directly into Google Calendar or another agreed calendar system. If the caller needs something that requires a human, such as a formal quotation or a complex request, the AI should either: perform a warm transfer to a human representative, or collect the information and create a follow-up task for the team. Record calls and make transcripts available in the CRM. 2. WhatsApp AI Assistant I also need a WhatsApp-based AI assistant that shares the same knowledge base and CRM as the phone assistant. It should: Respond to WhatsApp messages 24/7. Understand French and Moroccan Darija. Answer approved questions about services, prices, opening hours, etc. Collect the same lead information as the phone assistant. Handle appointment requests. Allow prospects to choose an available appointment slot. Synchronize appointments with the same calendar used by the phone assistant. 3. Phone → WhatsApp Follow-up An important part of the system: When someone calls the business and provides a phone number, the system should be able to automatically send a WhatsApp follow-up message to that number after the call, where appropriate. For example: “Bonjour [Name], merci pour votre appel. Voici un récapitulatif de votre demande…” The exact workflow can be discussed during development. 4. Central CRM / Database Both channels must use the same central lead/contact database. For each lead, I want to automatically store: Name Phone number Email Reason for contact Appointment information Notes Call recording Call transcript WhatsApp conversation history Lead status Source/channel I should be able to see the complete history of a prospect in one contact record. 5. Admin / Knowledge Base I need a simple way for my team to update: Prices Services FAQs Opening hours Basic business information The team should not need to modify code for normal content updates. Deliverables Complete phone AI receptionist Complete WhatsApp AI assistant Shared knowledge base Shared CRM/database Google Calendar integration Phone → WhatsApp follow-up automation Call recording and transcription Lead/contact data extraction Human handoff/follow-up workflow Admin interface or simple method for updating FAQs/prices Deployment/configuration Testing of the complete end-to-end workflow Brief documentation explaining how to operate and update the system What I expect from you In your proposal, please include: Your recommended architecture Technologies/platforms you would use and why Examples of similar AI voice/WhatsApp automation projects you've built How you would handle French + Moroccan Darija How you would implement the shared CRM/database How you would handle phone-to-WhatsApp follow-up Estimated development timeline Estimated cost Any third-party services/accounts I will need to pay for separately Important: I want the system to be production-ready, reliable, and easy for a non-technical team to manage after deployment.

The part that decides whether this works isn't the voice AI, it's getting a phone call and a WhatsApp thread to land on the same lead record in your CRM without someone stitching them together afterward. That's what I'd build first. Worth being upfront about Darija: French speech recognition is solid out of the box, but Darija mixes Arabic, French and Berber, and most engines don't transcribe it cleanly. I'd run it as a hybrid, French handled natively, Darija routed through a model tuned closer to dialectal Arabic, and I'd rather say that now than promise clean recognition and have you find the gap on a live call. Calls and WhatsApp both write into one lead record with the recording and transcript attached, booking goes to Google Calendar, and anything the bot can't resolve hands off to a human mid-conversation. After the call, a WhatsApp follow-up fires on its own. Prompts, hours and templates sit in a simple panel your team can edit without touching code. M1: intake plumbing, CRM lead schema, Calendar booking, $250, 5 days. M2: bilingual voice flows, recording/transcript logging, human handoff, $275, 6 days. M3: automated WhatsApp follow-up, editing panel, testing and tuning, $225, 5 days. 750 covers what's in the brief. If call volume or the number of WhatsApp templates comes out bigger once scope is locked, I'll flag it before M2, not after. Is the CRM something you already use, or should that get built as part of this?

I understand you're looking for an AI voice receptionist capable of handling French and Moroccan Darija calls, similar to how many advanced virtual assistants manage multilingual customer interactions. My experience in developing robust natural language understanding (NLU) models and integrating them with telephony APIs allows for precisely this kind of sophisticated conversational agent. My approach will involve leveraging a state-of-the-art NLU framework (e.g., Rasa or Dialogflow) fine-tuned for your specific business context and target languages. For voice recognition and synthesis, I'll integrate with services like Twilio's Programmable Voice for call handling and Google Cloud Text-to-Speech for natural voice output. The conversational flow will be designed to capture the required caller details efficiently, with robust error handling and fallback mechanisms. Data will be structured for seamless integration with your CRM and calendar. To ensure the best fit, could you clarify the preferred method for CRM data synchronization (API, webhook, or file export)? Also, what level of complexity is expected for the "approved questions" – simple FAQs or more dynamic information retrieval? I’m eager to discuss how we can build a highly effective AI receptionist for your business.

Hi, I would build this using Vapi for the AI phone receptionist, WhatsApp Cloud API, n8n for orchestration, and Supabase for the shared CRM and knowledge base, with Google Calendar for appointments. Both channels would use the same contact data, conversation history, FAQs, lead status, and appointment flow. French and Moroccan Darija can be supported through the voice and language models, with controlled business knowledge to keep responses accurate. Phone to WhatsApp follow up would be handled automatically after eligible calls, with human transfer or task creation for complex requests. I have 3+ years of experience building AI voice agents, CRM systems, API integrations, and automation workflows, including similar lead capture, appointment booking, and follow up systems. For a production ready version, I would estimate 2 to 3 weeks, depending on the final call and WhatsApp requirements. The main third party costs would be Vapi/voice usage, WhatsApp messaging, AI model usage, phone number/SIP, and hosting, which you would pay directly. I can provide deployment, testing, documentation, and a simple way for your team to update the knowledge base without changing code.

Hello!! A voice receptionist chatbot can be built to answer calls, understand customer requests, provide accurate responses, collect caller details, and route or escalate conversations when human assistance is needed. * Which phone/voice provider should the receptionist use? * What types of questions and tasks should it handle? * Should calls be transferred to staff or appointments be booked automatically? The solution will include voice AI integration, speech-to-text and text-to-speech, conversational workflows, business knowledge integration, caller identification, appointment or enquiry handling, call routing, fallback to human staff, conversation logging, API integrations, and monitoring. Relevant AI chatbot, voice AI, automation, API, and customer-support projects have been completed before, creating conversational systems that reduce repetitive work while keeping escalation available for more complex requests. Let us discuss your receptionist workflow and existing systems so we can design the conversation flow around your actual business needs. Best regards Farhin B

Hi, I’m a Senior Software Engineer with 20+ years in AI automation and backend systems. I have gone through your specific requirement for AI receptionist automation. I built something like this for business clients handling automated customer workflows, including Apex Rescue OS and WhatsApp booking automation. I would use a shared Python/Firebase data layer instead of separate CRM stores because phone and WhatsApp histories need one contact record. I will build the voice workflow around transcription, intent handling and calendar actions. WhatsApp Cloud API will use the same knowledge and lead records, while call transcripts and follow-ups stay linked to each contact. And I’d test French and Darija flows with real conversation cases, at least that is where I would start. Relevant AI automation samples and screenshots I can send. Which phone provider and WhatsApp Business account do you already have? Which CRM is used today, if any? Which Google Calendar setup should handle the appointments? Free for a quick call this week? Or just answer those three and I’ll map the first version. Dev Singh

Hi, I'd start small on purpose here: one phone flow, one WhatsApp flow, both talking to the same contact record and calendar. What I'd leave out of version one is the warm call transfer to a human and multi-language switching mid-conversation. Those add real complexity, and it's better to get the core booking and lead-capture loop solid first, then layer that in once you've seen it handle real calls. For the build, I'd use a voice AI platform for the phone side, a WhatsApp Business API connection for messaging, and a shared database behind both so every lead shows up as one contact with call recordings, transcripts, and chat history in one place. Google Calendar handles the booking sync. Darija and French both need to be tested against real caller accents, not just text, so that's where I'd spend extra time early. Your team updates prices and FAQs through a simple form, no code touching involved. I've built voice-to-CRM flows like this before and the follow-up message trigger is the fun part to get right. This runs about 2 days start to finish. What calendar system are you on right now, Google Calendar itself or something else feeding into it? Best, Emrah

Hi, I’d build the phone and WhatsApp assistants around one shared backend, knowledge base, and contact record so conversations stay connected when someone switches channels. My proposed architecture is a managed voice platform connected to your phone provider, the official WhatsApp Business API, and a Python backend integrating your CRM and Google Calendar. Approved prices and FAQs would remain editable through an admin interface, with unsupported questions routed to your team. French and Moroccan Darija need testing with native speakers, including code-switching, local accents, names, and noisy calls. I’d validate voice recognition and pronunciation before selecting the final speech provider. Booking would include availability checks and duplicate-request protection. Human handoffs would pass the conversation context, while recordings, transcripts, and contact access would follow agreed consent and retention settings. Phone-to-WhatsApp follow-ups would require opt-in and approved templates where applicable, not simply a collected number. I’d test booking conflicts, failed transfers, API outages, and cross-channel contact matching, then document the separately billed telephony, WhatsApp, AI, CRM, and hosting services. Which CRM and business phone setup do you currently use, and is your WhatsApp number already connected to the Business API? Regards, Houssame

==== Hi - Truong here ==== "AI PHONE + WHATSAPP RECEPTIONIST" — you need both channels sharing the same leads, calendar, knowledge, and conversation history I’d use a shared backend/CRM as the single source of truth, with the phone and WhatsApp agents using the same business knowledge and appointment rules. For Darija, I’d test real call and message samples rather than relying only on generic language support, especially around mixed French/Darija speech and human handoffs. Should the CRM be built from scratch, or do you already use a CRM that I should integrate with?

Hi We are available to take this on and get your AI receptionist and WhatsApp automation working perfectly. The main issue with multi-channel setups is usually ensuring the voice and chat models share a unified knowledge base and state without syncing delays. Are you planning to use Vapi or Retell AI for the phone agent with Twilio, and do you want the CRM built on a custom Node.js/Python stack or a standard platform like GoHighLevel or Airtable? We recently fixed a similar multi-channel AI system for a logistics firm that needed voice and WhatsApp workflows tied to a central database. I used Python with OpenAI's APIs, Twilio for voice/WhatsApp handling, and Retell AI for natural bilingual conversation routing while building an admin dashboard for FAQ updates. I corrected their webhook architecture to prevent dropped call context during handoffs. Our fix stopped their lead data from being lost during busy hours and made the whole booking process way faster for their team. We are eager to discuss the project further. Reach out to initiate a conversation! Best regards, Quantum Code Solutions

The hard part of this build isn't the phone bot or the WhatsApp bot separately, it's making sure a lead that starts as a phone call and continues as a WhatsApp follow-up shows up as one contact record, not two, with one calendar slot that both channels respect. I'd architect this around a single backend service holding the knowledge base, CRM, and calendar logic, with the phone assistant and WhatsApp assistant as two thin clients calling into it, rather than building either as a standalone bot. That's what makes the phone-to-WhatsApp follow-up and shared lead history actually reliable instead of synced after the fact. For voice, I'd use a telephony/voice AI stack like Twilio plus a real-time speech pipeline, since French is well supported, but Darija needs care, it's mostly spoken and mixes Arabic and French, so I'd tune the speech recognition and response prompts specifically on your call recordings rather than trust a general multilingual model out of the box. WhatsApp would run on the official Business API so slot selection and message delivery stay reliable at scale. Appointments write to Google Calendar as the source of truth for both channels, and anything needing a human, quotes, complex requests, creates a follow-up task rather than blocking the caller. For updates, prices and FAQs would live in a simple admin panel your team edits directly, no code involved. What calendar and phone number setup are you currently using, so I can size the integration accurately?

Hello, I’d build this as a production-ready AI voice + WhatsApp system with a shared backend, so every call, chat, lead, transcript, and booking lives in one place. For the voice layer, I’d use AI Voice Agents with a reliable telephony provider, then connect it to an AI Chatbot layer for WhatsApp, all powered by a single knowledge base and CRM/database. For French and Moroccan Darija, I’d use multilingual speech recognition plus intent handling tuned with custom prompts, approved FAQs, and fallback rules for human handoff. I’d store lead data, call recordings, transcripts, WhatsApp history, status, and source/channel in one central CRM, with Google Calendar sync for booking and availability. For updates to prices, services, FAQs, and opening hours, I’d create a simple admin interface so your team can edit content without code. I’ve delivered AI Integration and automation flows where reliability, auditability, and clean handoffs were critical, and I’d structure this to be easy for a non-technical team to run. Estimated delivery: 4-6 weeks depending on platform choices and testing scope. Third-party costs may include telephony, WhatsApp API, speech-to-text, and hosting. Best, Panagiotis
