I need some help with a Magix. I am trying to point a DID to a calling group so outside callers will connect directly to the group members. I was told that I could re-number an existing calling group to the DID that I plan on using and that should do it. I renumbered 771 to 5811 (DID) and added 3 members to 5811 but no phones ring when I call the DID. I selected "ring all" for the hunt type. Am I missing something?
