Is there as implementing a totalizer of minutes for the calls? In the list of calls he/she would appear the duration of each call and his/her total regarding the month!
But if the software he might have this option facilitate the screening!. And the confrontation with the account from operator without the need to remain resetting the counters all month into the phone. understood?
Better you reset the call-meter every month. Its not enought to count the minutes called with MyPhoneExplorer and i have no access to the callmeter inside the phone.
