Thanks for the refresher 101 course. I understand the basics. Our LD provider is telling us that they are sending DNIS digits of 2xxx to our PBX, at that point we determine what trunk group it rides over; that's what I am trying to determine how the PBX is programmed to choose a specific trunk group for incoming calls. Or does the LD/LEC provider determine which T1 to send the DNIS digits to and that's how it gets to a specfic trunk group in our PBX.
