1.Configure Billing

You as a VoIP Services provider, are already running a VoIP Billing Server. You will need to enter the service URL for initiating a callback request. This URL can be obtained from your Billing software provider.

2.Add Keywords

Two keywords MAKECALLBACK & GETBALANCE are provided with the application. You can click on “Enabled” checkbox on each keyword to provide that functionality.


Now your application is ready to provide SMS callback functionality to your VoIP customers. Just give them the android phone’s mobile number, and the callback format “MAKECALLBACK NUM1,NUM2”. Click on the start button to start accepting SMS requests.
