GoIP Series

A VoIP GSM gateway (GoIP) is an IP-based device that enables inbound and outbound

VoIP and GSM cellular calls. It is a great alternative to a VoIP FXO gateway,

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’s 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. A

VoIP GSM gateway 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 FXO gateways

System Highlights � Extensive product compatibility with

industry leading vendor

� Easy to install – IP device with Web based management interface

� Can be managed and monitored remotely over Internet - a great service

to offer to customers by system integrators

� GoIPs can be grouped together to

establish GSM gateway cluster � Termination between GSM/VoIP

� Schedule or on-demand SMS Broadcast messages to users

GoIP-1

GoIP-4

GoIP supports both GSM850/1900 (for North and South American) and GSM900/1800 (for Europe and Asia, except Japan and Korea).

The GoIP Web management interface provides real-time signal strength and system status for

each GSM channel. This helps administrator to identify the best installation location and diagnose anomaly. Optional external antenna

is also available to boost reception quality and to eliminate interference.

Configuration Examples:

GoIP connectivity with IP-PBX in a

local network

� GoIP1 or GoIP4 is connected to IP-PBX

in a local network

� Incoming calls: A call initiated from a local cell phone or PSTN network to GoIP1 or GoIP4 is routed to IP-PBX

� Outgoing calls: A call initiated from IP-

PBX is routed to GoIP1 or GoIP4 and

then terminate to the local GSM or PSTN network

� Optional user authentication for

enhanced security and thief-of-service protection

GoIP connectivity with IP-PBX through Internet or IP network

� GoIP1 or GoIP4 at a remote location is

connected to IP-PBX through Internet or IP network

� Incoming calls: A call initiated from a

local cell phone or PSTN network to GoIP1 or GoIP4 is routed to IP-PBX

through Internet or IP network � Outgoing calls: A call initiated from IP-

PBX is routed to GoIP1 or GoIP4

through Internet or IP network, and then terminate to the local GSM or PSTN

network

� The GoIPs can be setup in GSM Group Mode to provide line hunt service � A Server unit (master) controls all Client mode units, and the server unit phone number becomes the main phone number

� The Client mode GoIPs periodically report status (busy or idle) to Server. � Administrator can easily add additional lines to expand capacity

Sending bulk SMS

� Standalone GoIP can be used to send bulk

SMS, i.e. no IP-PBX is required � Optional SMS Server software to manage

SMS broadcast

� SMS Server allows “Same Carrier Network” identification for each target number. SMS

Server chooses the proper GoIPs to send SMS within the same carrier network. This could be a significant cost saving depends

on service plans. � Administrator can access the SMS Server

remotely to manage phone number database, edit SMS content, send SMS, and monitor SMS status.
