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 departments & agents
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.
Chat departments & users
Like all Usergroup permissions, user chat department permissions are set through usergroups.
Usergroups control which departments users can select when they initiate a chat.
