1 Overview
1.1 Introduction
The GoIP series gateway is a broadband relay gateway newly developed by VOPTEL
Technology. It is a new product for seamless connection between the GSM network and VoIP
network. When the mobile phone SIM card is installed in the GoIP, users can register the
GSM phone to the VoIP softswitch system. Through the GoIP, users can realize the uplink and
downlink calls between the GSM network and the VoIP network. In addition, the GoIP
supports the transparent transmission of the caller number from the PSTN to the VoIP. The
GoIP features embedded SIP and H.323 protocols with flexible setting. The bi-directional
password authentication (call authorization) and trust list authentication greatly minimize the
risk of charge losses and the flexible routing function can meet special requirements of
various call forwarding. In particular, the GoIP gateway supports multi device groups, with
flexible setting of large GSM gateway groups with different channel numbers. With its low
price, excellent voice quality, and powerful features, the GoIP series gateway is the first
choice for system integrators, traffic operators, and softswitch manufacturers.
The GoIP series gateway includes GoIP-GSM, GoIP_4 and GoIP_8.
