WhatsApp Gateway
Connect WhatsApp's 2 billion users into your existing VoIP Infrastructure.
Our WhatsApp Gateway is an add-on product that brings browser- and app-based voice calling from WhatsApp to your VoIP infrastructure, without replacing it.
It registers directly to your existing SIP server as a standard SIP endpoint, bridging WhatsApp clients to your telephony landscape transparently.
Calls made from WhatsApp-Web or WhatsApp mobile app reach your existing users, extensions, and PSTN connections just like any other SIP call.
