Dinstar 16 Port LTE 4G GSM Gateway - UC2000-VG-16T

The Dinstar UC2000-VG-16T is a carrier-class 16-port GSM/WCDMA/LTE VoIP gateway designed for organizations that require high-density mobile voice and messaging integration with their IP-PBX or softswitch systems. It supports up to 16 concurrent mobile channels and offers seamless voice bridging between mobile and VoIP networks with exceptional reliability and call quality.

Engineered for continuous 24/7 operation, the UC2000-VG-16T features dual Gigabit Ethernet ports, hot-swappable SIM cards, and remote SIM management via Dinstar SIMBank/SIMCloud solutions. Its comprehensive support for SIP v2.0, SMS/USSD APIs, and SMPP integration makes it ideal for telecom operators, call centers, and enterprise VoIP infrastructures.

With future-proof VoLTE capability and automatic fallback to 3G/2G, this gateway ensures compatibility across diverse carrier environments as networks migrate to full-LTE ecosystems. The system also provides flexible routing, number manipulation, traffic control, and detailed call statistics through an intuitive web interface.

Key Features

• 16-channel GSM/3G/4G LTE (VoLTE-ready) connectivity

• SIP v2.0 compliant for IP-PBX and VoIP platforms

• Supports SMS, USSD, HTTP, and SMPP APIs for bulk or app-based messaging

• Dual Gigabit Ethernet interfaces for redundancy and speed

• Hot-swappable SIMs and remote SIM management (SIMBank/SIMCloud)

• Intelligent least-cost routing (LCR) and prefix-based call rules

• Advanced voice optimization: echo cancellation, VAD, CNG, jitter buffer

• Compact rackmount 1U chassis suitable for carrier or enterprise use

• Secure signaling and media encryption with TLS/SRTP

• Web GUI, SSH/Telnet, SNMP, and HTTP/TFTP provisioning

Future-Proof Design
The UC2000-VG-16T combines LTE/VoLTE voice with full backward compatibility for 3G/2G networks. As carriers evolve to all-IP mobile voice, this model guarantees long-term viability with scalable configuration and multi-band compatibility. Remote SIM and VoIP provisioning allow easy expansion without physical access — perfect for distributed or data-center deployments.
