Brand New 4 port GOIP GSM gateway

GoIP VOIP Gateway GSM Converter

SIP IP Phone Adapter

Quad Band 4xGSM SIM Gateway:

Trunk to Asterisk iP PBX

 

Description:

The GoIP series gateway is a broadband relay gateway 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. 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

 

Summary:

GoIP GSM Gateway bridges the GSM services and the IP networks. It is ideal for VoIP to wireless services where a fixed telephone line (PSTN) is not available or for cell phone roaming via the VoIP network.

Free roaming:

In order to promote our product ,Now we have added some new funcitions in GoIP.By adding the new funcitions,you can build the call without using the softwhich or platform,just depending on the internet.it makes our calls more convenient and easier.what’s more, it can save a lot of call fee.Here is the following example:

Example:

peer to peer:it is a new function that you can use our voip without platform,what is more,it is free roaming for international call.you just pay the local call

MODEL 2

MODEL 3

MODEL 4

 

Applications:

1. Call Forward

a. Call Origination refers to a call initiated from the PSTN or cell phone network is terminated using VoIP.
b. Call Termination refers to a call initiated as a VoIP call is terminated using PSTN or cell phone network.
c. 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.
- 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. IP PBX Call Origination and Termination

a. Instead of FXO gateways, GoIP are as a call termination and origination device for the IP PBX as shown in the diagram above.
b. VoIP endpoints connected to the IP PBX can make calls to cellular/traditional telephone network via the GoIP GSM ports.
c. Outside callers can then call in via the GoIP GSM ports to reach any of the VoIP endpoints that are registered to the IP PBX.
d. GoIP can be configured in a group mode such that all GSM ports can be used by just dialing only one GSM number. Please refer to the Call Center Application for more information.
