Dinstar 8 Port LTE 4G GSM Gateway - UC2000-VE-4T

The Dinstar UC2000-VE-8T is an advanced 8-port LTE/VoIP gateway that bridges mobile and VoIP networks with superior efficiency and flexibility. Each of its eight channels supports GSM, WCDMA, and LTE (VoLTE), enabling simultaneous mobile voice and SMS connectivity for enterprise communication systems, call centers, and service providers.

With SIP v2.0 compliance, hot-swappable SIMs, and remote SIM management capability, the UC2000-VE-8T integrates easily with IP-PBX, softswitch, or hosted VoIP platforms. It supports two Gigabit Ethernet ports for network redundancy and offers comprehensive APIs for SMS and USSD applications — making it perfect for both telephony and messaging services.

Engineered with future-proof technology, this gateway ensures long-term operability as mobile carriers transition to all-LTE and VoLTE infrastructures. Its robust hardware, flexible configuration, and carrier-grade voice quality make it ideal for high-volume deployments and critical communications.

Key Features

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

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

• Supports SMS, USSD, HTTP, and SMPP APIs for applications

• Dual Gigabit Ethernet ports for LAN and redundancy

• Hot-swappable SIM cards with remote SIM management (SIMBank/SIMCloud)

• Automatic fallback from LTE to 3G/2G for carrier flexibility

• Advanced call routing and least-cost routing (LCR) logic

• Web GUI, SSH/Telnet, and auto-provisioning support

• Voice enhancement with echo cancellation, VAD, CNG, jitter buffer

• Rugged 1U metal chassis for continuous 24/7 operation

Future-Proof Design
The UC2000-VE-8T supports VoLTE voice over 4G while maintaining backward compatibility with 3G/2G networks. It is built to adapt to future network upgrades and carrier migrations without hardware replacement. Remote SIM management and multi-band LTE capability ensure full scalability for regional or global deployments.
