Allows users to route calls to any of their numbers (cell, office or home). A favorite feature of many Google Voice users is the transcription service. Google Voice can transcribe voicemails and send you an e-mail or SMS with the transcription (only available in the US). Admittedly the accuracy of the transcriptions does need some work, but it is usually enough to give the user a fair idea of what the sender meant to say.
Google Voice can also be used to make very cheap international calls to far away places – calls to Afghanistan costs just $.029 and those to Argentina costs as little as $0.03 per minute. On the other hand, you can also screen and block calls if you need to do so.
You can access and use Google Voice through a web browser, but the Android app version of the service makes the solution a better mobile VoIP solution for Android phones. Once you set up a Google Voice account and install the app you will then need to tell the app how to handle your calls. For example, you can have Google Voice handle all your calls or just the international ones.
If you choose to have Google Voice answer all your calls, the person you are calling will not see your phone number, but the Google Voice number that is being used. This is great if you want to keep your real number private, but it can cause some confusion to those who expect to see your old telephone number when getting a call from you. The app is free, even for sending text messages, but you will need to spend some money to access Google’s low international calling rates.
