Description

Overview

Dinstar MTG200 Trunk Gateway allows for direct routing of calls between fixed line ISDN and IP networks, providing businesses with the opportunity to take advantage of low-cost VoIP telephony. By seamlessly integrating Dinstar Trunk Gateway with existing PBX/PABX telephone systems, companies of all sizes can benefit from cost-effective Voice over IP calls and make considerable savings without the high upfront costs typically associated with upgrading their communications infrastructure to VoIP.

MTG200 offers PBX/IP-PBX users a powerful telephony cost-saving device and advanced flexible routing capabilities between ISDN PRI to SIP and also can be situated between the PBX and the PSTN, saving the cost of an additional PBX E1/T1 port. It is ideally fit for various access networks of SMEs, call centers, telecom operators, and large-scale enterprises.
