A Powerful GSM Gateway for Modern Business Communication

As businesses strive to balance cost efficiency, network stability, and mobility, the TG400 offers a perfect solution. It bridges VoIP and GSM networks to create a flexible telephony system that supports multiple call paths, smart routing, and high-quality communication. With four GSM ports, it significantly expands calling capacity, making it suitable for environments with high call loads or diverse routing needs.

1. Four GSM Ports for High Capacity and Redundancy

The Yeastar TG400 features four independent GSM channels, enabling simultaneous calls and support for multiple mobile carriers. This configuration provides excellent scalability for businesses that require higher call volume handling or carrier diversity.

2. Dramatically Reduce Mobile Calling Costs

By routing mobile calls through GSM rather than VoIP trunks, companies can cut communication expenses. The TG400 supports:

• Least Cost Routing (LCR)

• Time-based routing

• Caller ID routing

• Carrier-specific routing

These capabilities ensure each call follows the most economical path, maximizing cost efficiency.

3. Failover Support for Business Continuity

One of the TG400’s strongest advantages is automatic failover. If your SIP trunk or internet service goes down, the gateway reroutes calls through GSM, ensuring that your business never loses communication. This makes it ideal for mission-critical operations that cannot afford downtime.

4. SMS & USSD Support for Enhanced Functionality

The device is also a complete SMS solution that allows you to:

• Send SMS directly from the web interface

• Receive SMS into your VoIP system

• Automate SMS alerts and notifications

• Use USSD codes for balance checks and bundle management

This makes it an excellent tool for communication workflows that require SMS automation.
