TG800L Yeastar 8 port LTE 4G GSM gateway

The Yeastar TG800L is an enterprise-grade 8-port LTE/4G VoIP gateway, enabling efficient integration between mobile networks and IP-PBX/softswitch platforms. Designed to support up to eight simultaneous mobile channels across LTE/4G (with fallback to 3G/2G where required), the TG800L allows voice, SMS and USSD traffic to traverse mobile and VoIP domains seamlessly.

Built with reliability, scalability and future-proof connectivity in mind, the TG800L features dual Ethernet interfaces, broad codec support, advanced routing and traffic control, and a web-based management console for quick deployment. Whether used for mobile trunking, disaster recovery voice links, or bulk messaging services, the TG800L offers a highly flexible solution for businesses and service providers.

Key Features

• 8-channel LTE/4G mobile voice trunking (VoLTE-capable)

• SIP v2.0 / IAX2 support for integration with modern IP-PBX systems

• Supports SMS and USSD via HTTP API, suitable for applications and alerts

• Dual 10/100 Mbps LAN ports (for LAN/WAN separation or redundancy)

• Advanced call control: routing, prefix rules, least-cost routing (LCR)

• Web GUI, SSH/Telnet and remote provisioning for ease of operation

• Secure signaling (TLS) and media (SRTP), echo cancellation, VAD, jitter-buffer

• Compact, rack-friendly chassis for continuous 24/7 operation

Future-Proof Advantage
With LTE/4G voice support (VoLTE) and backwards compatibility with 3G/2G networks, the TG800L ensures your mobile trunking infrastructure remains ready for evolving carrier landscapes. Its modular design, combined SMS/USSD support and SIP interoperability make it a strong investment as mobile and fixed communications converge.
