How can I view the call duration after a call or during a call on my Nokia device?

To view the call duration for the last call, or total duration of received calls, dialled calls and all calls, select Menu > Tools > Log > Call duration (or in some devices Menu > Applications > Log > Call duration).To view the call duration during the call, select Menu > Tools > Settings > Phone > CallShow call duration > Yes before the call (or in some devices Menu > Settings > Calling > Call > Show call duration > Yes). When there is an active call, you can see the call duration in idle mode or in the telephone view.
