I am not yet a user of osTicket, but everything seems to be perfect. Just one question though, our service department handles about 1000 contacts every day. These tickets which are created are subject to multiple contacts and contact persons. For instance:Customers emails a though questionI forward the question to an external expertCustomer calls for a status updateI receive an answer from external expertI send the answer to the customerSo, 3 different email addresses, 2 different e-mail subjects all beat with ticket ID in subject, 2 different channels.Is osTicket able to make every contact which are mentioned above to be merged into 1 ticket?Is osTicket able to use only e-mail on the customer side? I don't want our customer to have to log in somewhere.We have an IT department which are used working with PHP and SQL, so no problems there, little tweaks are no problem.
