Does anyone in the group have multiple OTRS systems that interact with each other? If so give an example of how it is set up. Currently I have two systems in my enterprise and I was having hell making the two systems share tickets. Originally I had the tickets set up identically except for the system ID example (Ticket# 20071005102127 system ID is 10) and (Ticket 200710051226 system ID is 12). I would create a ticket in one system and send an email to the other system through composing an email from the ticket itself. This would create a new ticket on the other system. (All is well). When I tried to respond to the originating system from the newly generated ticket, instead of appending the original ticket it would create a new ticket. I found that system ID served no purpose. I had to completely change the ticket hook from Ticket# to something like NYTicket# 20071005102127 and LATicket# 200710051226. Only after this change could I append tickets back and forth between both systems. If any one knows of a better more efficient way to have multiple systems interact with each other, please feel free to lay it out
