Displaying and Assigning Call Charges

For the current call:

The display usually shows call charges at the end of a call (default setting).
If you wish to display charges continuously during a call in progress, service personnel must request this feature from your carrier.
Some carriers also let you display toll-free external calls. The message "Free of Charge" appears on the screen either before or during the call. 

If a call is transferred, the charges are assigned to the telephone to which the call was transferred.

For all calls and the last one conducted:

The connection charges for the last chargeable call conducted are displayed first. Five seconds later, the total accumulated connection charges appear.
