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
GoIP is designed to work in conjunction with key phone systems and
IP-PBX to provide GSM communications. The extensive compatibility
of the GoIP makes it an ideal choice to be deployed in multi-vendor
open architecture VoIP networks. GoIP is a great way to provide
fast phone service deployment where regular PSTN line may not be
readily available. GSM gateway also provides significant savings in
usage, infrastructure and maintenance cost compared to conventional
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.
1) Call Forward
1.Call Origination refers to a call initiated from the PSTN or cell
phone network is terminated using VoIP.
2.Call Termination refers to a call initiated as a VoIP call is
terminated using PSTN or cell phone network.
3.As shown in the network topology diagram, a VoIP Service Provider
is using GoIPs as call origination and termination devices.
4.A call dialed to a GoIP (right hand side) via GSM is first routed
via VoIP and then terminated via a VoIP end point or VoIP Service
5 .A VoIP call originated from the left hand side is routed to a
GoIP on the right hand side and then is dialed out as a GSM call.
2) Call Back
1,Call Back is referring to the telecommunications event that
occurs when the originator of a call is immediately called back in
a second call as a response.
2,GoIP could be used to achieve this function alone or as an
terminal that is integrated in an existing call back server /
3,For standalone operation, GoIP receives a call with caller ID
information and then rejects the call immediately without answering
the call. GoIP then calls back the caller so that he can dial a
phone number to make a call. In this case, GoIP must register to a
VoIP Service Provider who can offer terminate the call.
4,In a call back system, GoIP acts as a device to initiate the call
back function. Typically, this is done in two ways. The first
method is to send an SMS with the callee’s phone number to the
GoIP. The GoIP then sends both the caller’s and callee’s phone
numbers to the call back server to complete the call back function.
The second method is to call the GoIP and the hang up (with the
call being answered). GoIP sends the caller’s phone number to the
call back server and the call back server calls the caller directly
so that the caller can then dial a phone number to make a call.
