Your Telnyx number can now receive and place WhatsApp voice calls on the same connection you already use for SMS, WhatsApp messaging, and programmable voice. No separate integration, no new provider, no new stack.
WhatsApp has 2B+ users and is the default communication channel in much of Latin America, South Asia, and Africa. With WhatsApp Calling on Telnyx, your existing Voice API, SIP, TeXML, and AI agent connections now reach those users too. If you have an AI agent answering calls on your Telnyx number, that agent now reaches WhatsApp users. If you route calls through a SIP trunk or TeXML app, WhatsApp calls follow the same path.
Outbound calling to WhatsApp numbers is also supported. Outbound calls use a dedicated SIP subdomain, so Telnyx can route them through Meta's network automatically.
Pay-as-you-go on business-initiated call minutes. No monthly subscription, no per-seat commitment. Inbound calls from WhatsApp users are standard call routing.
