RingPad

RingPad is the modern day international calling card. Make internet calls and your recipients receive them as regular phone calls with valid caller IDs.
No more worrying about data availability on the other end of the call. No more entering of pins and jumping through hoops to setup pin-less access and speed dial numbers.
Want to redial your friends later? Go to your phone's recent calls and tap a "RingPad Audio" entry. The call will be initiated over RingPad without opening the app!
