I currently am using a Nec 2400 and we require account code authorization for long distance calls, problem is that when this 6 digit code is entered it appears on the display of phone and then can be recalled by an unauthorized person.
Is there any way to masy these codes or we are going to be forced to remove the display phones from service??
