Using Skype and Google Voice together
One important factor to take into account is that these two VoIP products have the potential to work together, and a combination of the two may be beneficial to certain businesses and individuals. To use both products together, you first need to buy a Skype phone number. Once you have a personal Skype number, you can then set up Google Voice to forward any calls from your free Google Voice phone number to your Skype number, as well as to any other mobile or landline phone.
