Dial Options Outbound Route

I can set Dial Options in Extensions and Trunks, but not in the outbound routes level. I would like to remove the “tT” dial options to some destination patterns, so the dtmf will not be used to transfer.

I am reserving one of our trunks for this, removing the the dial option “tT” to make it work. But that is not the best solution, since the trunk will not transfer some situations it should.

What could i do? I really made a research but no results.

Thank you all!
