A linear hunt group always targets the first member in that group. A distributed hunt group distributes a call evenly among the group members. On the Toshiba DK, program 33 specifies a linear hunt group. Program *40 creates a disributed hunt group.
If you created a DHG in *40, the default pilot number is 850 for that group. Use program *04 to change the DHG pilot extension. To ring a group of extensions at the same time, you will need to use a phantom extension and place it on each member's phone. When the phantom extension is called it rings on those phones that have it on a button. Use programs *33, 39, and *71-*73 for phantom extensions.
