Place or join a call
Place a call from the call list by tapping the large plus button at the bottom of the screen to manually enter a number or to access your address book. If you have a conference call scheduled today, and you’ve enabled the Google Calendar integration, it will appear at the top of the call list under “Today’s Events”.
To cancel a call you've already initiated...
Press "accept" when Rambl calls you, then hang up. Declining the call will treat your voicemail as if you had answered and continue to connect the other party. We are working to address this in a future release.
To redial a call...
Tap the phone button to the right right of a recent call entry.
