Overview

 

The UTG7104-22(S/O) is a cost effective and highly reliable Voice over IP (VoIP) gateway that offers toll quality voice and real-time fax data over IP networks. With its embedded architecture, UTG7104-22(S/O) is ideal for VoIP applications associated with Small-Medium size Business (SMB), Remote Office and Branch Office (ROBO), and ISP/ITSP service markets.

 

The UTG7104-22(S/O) has user friendly interfaces and it may be installed easily and conveniently with VoIP management tools to yield immediate cost savings. Implemented with an efficient Real-Time Operating System (RTOS) and FLASH memory, UTG7104-22(S/O) provides field upgradeable capabilities, so, it may be programmed with updated protocols or algorithms locally or via the network at anytime. It comes equipped with remote management capabilities, configurable signaling to work with PBX or telephone. Utilizing advanced VoIP related technologies, it includes various voice coders and fax algorithms, echo cancellation, Voice Activity Detection (VAD), Comfort Noise Generation (CNG), and packet recovery algorithms.

 

EUSSO's Internet Telephony Gateway family supports Voice over IP (VoIP), as well as Fax over IP (FoIP), and it seamlessly bridges existing PBX or phones with IP networks. Its scalability satisfies user’s needs for system growth without additional software or complex integration.
