JIRA Service Desk integration?

As I just discussed the same in a different forum I thought I give you some further insight about my idea:

I am looking for a solution that also allows to directly create a support ticket out of a forum discussion. The community should try to help themselves, however if necessary they should be able to directly trigger a support case out of the discussion.

A ticket should be created and the support staff be notified about that (which is already business of the ticketing software). However, he/she should be able to quickly jump to the link of the discussion as well.

I assume this is a bi-directional integration and I am interested specifically if something like that exists for JIRA Service Desk or Zendesk Support?
