  • I have an Atlas 550 that I have configured three BRI slots to hunt, using the same number for In#Accept with incremented SPIDS.  Two questions:  First, is it possbile to have the last BRI in the hunt group hunt next to an FXS port in the box.

    Second, is it possible to have that FXS port call out when it receives a routed call from the hunt group?
