Ok, that kinda went over my head, so I will have to try to figure that out first.
Another thing I just found was "Intercept Handling" that might also work?
Originally the issue was internal local extensions calling our TF when they could just dial the switchboard extension so, if I can intercept all extensions calling the TF and re-route to a local extension that would also be a solution.
Anyways, have a LOT to learn about configuring this system, but for sure, your help is really appreciated!
