When Dial Through toggle is off, outgoing calls will not be routed through the telephone system unless the number being called is included on the whitelist or it is an internal extension; these always go through Dial Through.
Dial Through toggle affects calls made via your device's keypad, log and contacts except when the number being called is on the whitelist or blacklist.
Note: This feature requires a Wi-Fi/3G data connection or better.
