If you have an Android phone (such as the T-Mobile G1 or the MyTouch), you can now automatically place calls through your RingCentral account. I got tired of having to punch the numbers in for the calling card, so I made this application.
Note: You must have a RingCentral account for this application to work.Since you are calling through your RingCentral number, your caller id will show up according to your settings in your RingCentral account. It integrates directly with your regular contacts & dialer. The only setup you need to do is to provide your RingCentral Number and PIN. Easy! Please note, I made this application myself -- it is not produced by RingCentral Inc.
