I. Overview
1.1 Introduction
The GoIP series gateway is a broadband relay gateway newly developed by DBL 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, GoIP-4 and GoIP-8.
