I believe that status or category is deemed "isanswered". If I am mistaken then please correct me but I am fairly certain that is the purpose of that status.
That is not the purpose of that status.
I'd like to have an "On Hold" and "Waiting on Customer" status as well. They will need to stop the timer. However, I don't think oSTicket has a timer. It just specifies the created date and closed date in order to calculate total ticket time.
The "On Hold" and "Waiting on Customer" fields would be great though. I am going to work on this as a project. Should just be a few additions in the MySQL tabels and a few of the php files to create this.
EDIT:
Found the addition here - http://www.osticket.com/forums/showthread.php?t=2800(http://www.osticket.com/forums/showthread.php?t=2800)
Does not affect time though.
