GSM VoIP Gateway

GSM VoIP Gateway

General Information:

The GoIP GSM enables direct routing between IP and GSM network without the use of a FXO port or the PSTN network.It is the GSM network and the VoIP network connecting seamlessly new products. Mobile phone SIM cards will be installed in the device, and GoIP users can be achieved through the GSM network on the car aligh.It bulit-in SIP and H.323, configuration flexibility. SIP can be thoroughly used when electricity came display numbers. With this GoIP, the usage of VoIP is greatly enhanced with significant savings on long distance and roaming charges.

Application case:

A1: Sending Bulk SMS Service

  1. Sending bulk sms text messages is a common technique for telemarketing to reach the target customers.
    A bulk SMS system can
  2. be implemented quickly and easily using GoIPs and our proprietary SMS server. Telemarketers are no have full control on how and when they want to send text messages.
  3. In addition, SMS text messages are now used widely in many companies, organizations, schools, clubs as a mean for broadcasting information. They can now build their own SMS system without paying expensive charges to their GSM server provider.
  4. This system can also take the advantage of using the same GSM service provider to send sms to the phone subscribers in the same service provider.

A2: 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 / platform
  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.
