16 Ports GSM-LTE VoIP Gateway

GSM/LTE VoIP Gateway is a device that acts as a bridge between a GSM/LTE mobile network and VoIP (Voice over IP) networks. It enables communication between 4G/3G/2G networks (using cellular SIM cards) and IP-based networks (using VoIP protocols). Moreover,it allows users to build their own application software to send SMS/USSD messages or bulk SMS messages, or push their text messages from email, HTTP etc.

Key features of GSM/LTE VoIP gateway:

  • Channel Capacity: support up to 16 channels, allowing for simultaneous GSM or LTE connections for voice calls or SMS.
  • Network Compatibility: The gateway is compatible with various network technologies, including LTE-FDD (Frequency Division Duplex), LTE-TDD (Time Division Duplex), WCDMA (Wideband Code Division Multiple Access), and GSM networks.
  • VoIP Platform Compatibility: The gateway is designed to work seamlessly with mainstream VoIP platforms, ensuring compatibility and interoperability.
  • Hot Swappable SIM Cards: The gateway supports hot-swappable SIM cards, allowing for easy replacement or addition of SIM cards without interrupting the operation of the gateway.
  • Voice over LTE (VoLTE): It supports voice calls over LTE networks, providing high-quality voice communication using the LTE network infrastructure.
  • SMS Application Integration: The gateway offers an HTTP API that allows SMS applications to integrate and communicate with the gateway, enabling interactive SMS services and applications.
  • SMS and Email Integration: It allows for bidirectional communication between SMS and email platforms, enabling the conversion of incoming SMS messages to emails or vice versa.
  • Flexible Dial Rules and Manipulation Rules: The gateway provides flexible dialing and manipulation rules, allowing administrators to configure and customize call routing and number manipulation based on specific requirements.
