Yeastar TG1600 16-Port VoIP GSM Gateway
The Yeastar TG1600 is a 16-channel VoIP GSM gateway designed to connect mobile networks with VoIP communication systems. It provides 16 4G channels and two 10/100 Mbps Ethernet interfaces, allowing organizations to integrate cellular voice and messaging services with SIP-based communication infrastructure.
The TG1600 supports SIP and IAX2 voice processing protocols along with UDP, TCP, TLS, and SRTP transport. It supports multiple voice codecs including G.711, G.726, G.729A, GSM, ADPCM, and Speex, while ITU-T G.168 LEC echo cancellation helps support voice communication. The gateway also provides SIP server functionality for IP phones and supports 1-stage and 2-stage dialing.
Designed for flexible mobile communication management, the gateway supports 4G LTE bands depending on the installed module type. Where supported by the carrier, VoLTE is available, along with SMS sending and receiving, bulk SMS, USSD, carrier selection, caller ID/CLIR, and an Open API for SMS and USSD. These capabilities make it suitable for VoIP-to-mobile connectivity, business communications, SMS applications, and cellular voice integration.
The TG1600 includes incoming and outgoing routing rules, mobile port groups, VoIP trunk groups, blacklisting, hotline, AutoCLIP, call transfer, callback, call duration limitation, CDR, call status display, and system logging. Network and security functions include firewall, VLAN, QoS/ToS, OpenVPN, static NAT, STUN, DDNS, IP blacklist, and network attack alerts.
With web-based configuration, firmware upgrades through HTTP/TFTP, configuration backup and restore, packet capture, and multiple network management protocols, the TG1600 provides centralized management for business VoIP and mobile communication deployments. Its 440 × 280 × 44 mm chassis and AC 100–240V power supply support installation in suitable communication and networking environments.
