Description
The Yeastar NeoGate TG1600L is a high-capacity 16-channel LTE/4G VoIP gateway designed to connect mobile LTE/3G/GSM networks with SIP / VoIP telephony systems. It’s built for businesses, telecom providers, call centers, and large organizations that need mobile trunking, bulk voice routing, backup telephony, or cost reduction for mobile calls through SIM-based communication integrated with IP telephony.
The TG1600L supports 16 LTE channels / 16 SIM cards, enabling simultaneous two-way communication between VoIP and mobile networks: VoIP-to-LTE/GSM and LTE/GSM-to-VoIP. This makes it especially suitable for environments with high mobile traffic, such as service providers, contact centers, multi-branch enterprises, logistics operations, and remote business sites where mobile connectivity is either more economical or more practical than fixed-line infrastructure.
As part of Yeastar’s TG Series mobile gateways, the TG1600L supports SIP and IAX2 protocols and works with a wide range of IP PBX systems, hosted PBX platforms, SIP servers, and softswitches. It includes advanced telephony features such as incoming/outgoing call routing, Least Cost Routing (LCR), callback, hotline, blacklist, AutoCLIP, call duration limitation, call transfer, CDR, USSD, and SMS sending/receiving including bulk SMS. It also supports Open API for SMS and USSD, which makes it useful for business messaging, automation, and telecom integration scenarios.
For mobile connectivity, the TG1600L supports LTE / 4G voice services with backward compatibility for 3G and GSM, depending on the regional module version and supported frequency bands. It also supports VoLTE where available from the mobile operator. Voice quality and interoperability are supported through ITU-T G.168 echo cancellation, G.711 / G.726 / G.729A / GSM / ADPCM / Speex codecs, and DTMF via RFC2833, SIP INFO, and In-band.
On the networking side, the TG1600L includes 2 × 10/100 Mbps Ethernet interfaces, plus support for OpenVPN, VLAN, QoS, firewall, DDNS, static route, static NAT, STUN, backup/restore, packet capture, and web-based management. It also supports external antennas and optional antenna splitters to simplify larger multi-channel deployments.
Overall, the Yeastar TG1600L is a scalable 16-port LTE VoIP gateway for organizations that want to integrate mobile networks into SIP telephony, reduce mobile call costs, and add a resilient alternative voice route for business continuity and large-scale mobile communication.
