[otrs] Moving to the "mother" queue when no response

Hi! My name is Ronaldo. I'm new to OTRS and I'm planning to put it to work to handle the tickets generated by the site of my company (contact form). We here a structur of sales team and the queues in our otrs that reflects this is the following: Raw Junk Postmaster Sales - Unit 1 - Unit 2 Unit 1 and Unit 2 are sub queues of "Sales" queue. The system delivery the new tickets (via Postmaster Filters) to Unit 1 and 2. My question is: Is there a way move the tickets from the Unit1 queue to the sale queue automatically if a new ticket that is on Unit1 do not get answered or locked in 2 hours? Thanks and sorry my bad english :-) Ronaldo Richieri
