1. What is a VoIP Gateway (GOIP Gateway)?

A VoIP Gateway (also called GOIP Gateway) is a device that connects mobile networks (2G/4G) to IP networks. It lets you make voice calls and send SMS through both mobile networks and the internet. YX VoIP Gateway works with 2G GSM and 4G LTE networks, making it flexible for different regions and needs.

  • Making mass voice calls for notifications, reminders, or marketing
  • Managing multiple calls and messages at the same time
  • Integrating with IP-based systems (like SIP) for unified communication


3. How Does It Help Your Business?
