A few of the basic features are caller id, voicemail, call waiting, 3 way calling. Just about the same as the regular phone line.
The advance features are the best such as PC to Phone. This allows you to use your computer in making calls instead of your phone. You need special software for the feature.
Another one is that you can travel with it globally. You have the convenience of bringing it anywhere. You can bring the VoIP set up and have the high speed internet. You’ll be able to use the service. Have the convenience of calling your friends and family at home without the roaming charges and they can call you back as a local call. It does beat the service of the regular phone.
