I had this set up a long time ago, but that server died and I need to recreate it.
I have an old avaya pbx that is hooked up via a T1 line to my freepbx.
All the extensions on the avaya box start with 3XXX.
So in order to all calls from the freepbx to the avaya, I would make an outbound route to that trunk.
How would I though allow calls from the avaya device to go through the freepbx to be able to make outbound calls?
