No, you do not needs to install the software over your phone. I think you do not need the software to get the connectivity. You just connect with your PC with broadband to get the connection. Apart from the flexible connectivity, V-phone provides the emergency 911 services. It routed through the emergency centre to get the better connection so that VoIP user can access it very fast. It is most authentic services you ever look for in new brand of V-phone. I read the positive review of the users to get better outcome.
Once you subcribe to V-phone services than the customer care departmnt and technical team support you to get the proper result. You needs to contact the Vonage customer care centre in your local area and get the details. V-phone is easy to install but new users may have some problems so you must get the technical support from the local Vonage centre to gives the benefits. You must have to see the V-phone installation details to solve the problems.
