how to enable whatsapp calling in live kit project

Thanks for reaching out, Gaurav. I'm an AI assistant and I'm here to help. Give me a moment while I research this topic.

Thanks — I’m happy to help you explore this. You asked how to enable WhatsApp calling in a LiveKit project; I don’t have any built-in instructions for a direct “WhatsApp calling” feature in LiveKit, so I’ll need a bit more context to guide you to the best solution or an alternative. Could you tell me: • Which WhatsApp calling capability do you mean — voice calls, video calls, or PSTN-style calls to WhatsApp users? • Do you already have a WhatsApp Business API or a third‑party WhatsApp voice/video provider in mind? • Are you building a web, mobile (iOS/Android), or server-side integration? • Do you want LiveKit to handle media (signaling + media streams) while WhatsApp handles the user endpoint, or do you want to bridge LiveKit sessions to WhatsApp users? • Any code/SDKs you’re currently using, and whether you control the server that runs LiveKit rooms? With those details I can: • Suggest architectures that can bridge LiveKit to WhatsApp (if a bridge is possible), • Describe which parts LiveKit would handle versus what an external WhatsApp gateway would need to do, • Ask targeted follow-ups or provide example integration steps based on your platform. If you prefer, tell me your exact use case (example: “I want a web user in a LiveKit room to call a WhatsApp user’s phone and have audio connect”) and I’ll outline possible approaches and next steps.

i have whatsapp business account and verified phone no. i just want livekit for whatsapp calling only

Thanks — that’s helpful context. I’m sorry to say: LiveKit cannot enable WhatsApp calling. WhatsApp calling uses a proprietary protocol (not SIP or standard WebRTC) and is not accessible through LiveKit’s telephony features. LiveKit’s calling/telephony is built around SIP and PSTN providers (for example Twilio or Telynx) and cannot connect to WhatsApp voice calls even if you have a verified WhatsApp Business account. What you can do instead • Use a SIP/PSTN provider to call regular phone numbers from LiveKit. If your goal is to call phone numbers, LiveKit supports SIP trunks and phone-number integrations for inbound/outbound PSTN calling. • Use WhatsApp’s messaging features via the WhatsApp Business API for chat/notifications (but not voice calling). • If you specifically need to reach WhatsApp users by voice, consider third-party gateway services that claim to bridge WhatsApp voice to SIP or other networks. Be aware these are not standard, may violate WhatsApp terms, and are not supported by LiveKit. If you’d like, I can: • Outline how to set up SIP/PSTN calling in LiveKit (steps and required info). • Help evaluate architectures if you want a hybrid solution (e.g., LiveKit for web/mobile users + a SIP provider for phone calls). • Review any third‑party gateway you’re considering and point out what would be required to bridge it to LiveKit. Which of these would you like to do next?

i want to use livekit connector help me with it

Thanks — I’ll help you get set up with the LiveKit Connector. To be clear first: LiveKit does not provide a connector that enables native WhatsApp calling. LiveKit’s connectors are designed for SIP/PSTN integrations (telephony providers like Twilio, Telynx, etc.), which let LiveKit make and receive regular phone calls. If your goal is to reach WhatsApp voice calls specifically, that isn’t possible through LiveKit. If you want to proceed with a connector that LiveKit supports (so you can make/receive PSTN calls from LiveKit clients), I can walk you through the setup. To give the most accurate guidance, please tell me: • Which connector/provider do you want to use? (examples: Twilio, Telynx, your own SIP trunk) • Are you running your own LiveKit server or using a hosted LiveKit service? • Which platform(s) are your clients on? (web, iOS, Android) • Do you need inbound calling, outbound calling, or both? • Do you already have SIP credentials (SIP URI, username/password, trunk details) from your telco/provider? If you’re not sure which provider to pick, I can: • Recommend a typical architecture for using a SIP provider with LiveKit, • Outline the required steps and configuration options, • Provide example signaling flow and where to run the connector/service that bridges SIP to LiveKit rooms. Next steps I can immediately provide once you tell me the provider and environment: 1. Step-by-step configuration for connecting a SIP trunk to LiveKit. 2. Example server flow for creating a LiveKit room and bridging a SIP call into that room. 3. Client-side snippets to publish/subscribe audio for a web or mobile client. Which provider and platform should I prepare instructions for?
