4-Remote SIM Gateway GoIP4 is an IP-based device that enables inbound and outbound VoIP and GSM cellular calls. It is a great alternative to PSTN, especially in area where GSM service is available for VoIP call termination. A typical set up is shown as follow:

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 PSTN.

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.

Key Features

Basic Function

Applications:

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.

   - 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 Provider.
