We have a few issue types that we only want to direct people somewhere else. For example, we have a separate portal for corporate cell phones. If someone wants to open a ticket requesting a new phone or whatever, I don't want them to open a ticket with us. I want them to get a link to the other portal with instructions on how to use it or whatever,
I can link a knowledge base article, but the user can still ignore the KB article and open a ticket with us.
What's the best way to redirect requests like these?
