Chat departments are used to control access to chats in conjunction with usergroups and agent permission groups.
Chat departments are a separate system from ticket departments - creating a ticket department will not create the corresponding chat department. Manage them under Chat > Chat Departments.
Chat department permissions control which chats agents can accept.
Manage permissions for each department by going to Admin > Chat > Departments, and selecting the Permissions tab.
Unlike the two permission levels of assign/full access for ticket departments, chat department access is either on or off.
Like all Usergroup permissions, user chat department permissions are set through usergroups.
Usergroups control which departments users can select when they initiate a chat.
