I tried with the master -slave function, but it seems i need to create a master ticket from a slave one. Am i right?
It think the normal behavior would be that i could create or choose a already open ticket as master.
For example, a user calls asking the whole office doesnt have internet, and another, and another and another. After that we create a ticket regarding the whole office hasnt internet and linked the tickets of the users as slaves, when we close the master, the slave are closed and the clients get his notifications.
