This module is deprecated and will not get any update - unless further development is sponsored. Instead a feature addon to buy is available from Feature-Addons.de: http://feature-addons.de/otrs/Ticket/TicketTemplates.
This free add on adds a new item to the ticket menu. When you click on that menu item, you can choose what information of the existing ticket should be added to the template.
This can be for example the queue, the priority and so on. Then a dropdown is added to the "new ticket" forms (AgentTicketPhone and AgentTicketEmail) where the agent can choose what template should be used. As soon a template is chosen, the values stored in the template are set in the form.
This module is deprecated as most OTRS users don't want to create templates based on existing templates, but define new templates in the admin area.
Unfortunately I have to pay some bills (like everyone else) ;-) So I have to sell some of my modules, hence TicketTemplates is not available on OPAR. But I plan to put it on OPAR sometime in 2015.
The code and a bugtracker is available at http://github.com/reneeb/otrs-TicketTemplate.git.
