Program Overview

As communications network operations and broadband networks continue to evolve, NGN / IMS networks are gradually replacing the existing PSTN network. Business enterprises can now gain access through the IP network with almost no delay, intermittent or communication latency, or poor quality voice calls. The existing business telephone system (PBX) can make use of existing resources to access to the NGN / IMS to reduce communication, operation and maintenance costs.

The OfficeTen has the perfect combination solution to transform the VoIP business from PBX to "NGN / IMS + OfficeTen VoIP Digital Trunk Gateway (GTW)." OfficeTen VoIP Digital Trunk Gateways can be based on the user's need to achieve a variety of routes, such as retain the existing PBX business phone number and all outbound telephone numbers will go through the OfficeTen VoIP Trunk Gateway sent to the NGN / IMS network. The OfficeTen VoIP Trunk Gateway digital E1/T1 port received the original enterprise PBX and uplinked the WAN port to connect to the operator's IP online. So the corporate PBX without changing any settings added the outside board. This configuration is very simple and convenient.
