I have heard that there is a technology of Google whose name is Google voice. It is providing us one number for all of our phone how it can happen is that there is one number for all of our phone. I am not able to understand the problem. There is another option by which we can call free of cost how it can be. If they are giving free call then nobody has to pay the huge bill to service provider. I am not able to understand the Google voice strategy please elaborate whole features of it with valid reason.
