I came across varying options of setting up a phantom extension, for example, using PKM, spare ONS port, *nnnn etc. On a 3300 Cx R4.0, do you have to create a fake DN number in the Users and Devices Config form to give it a Name and select "No Device" in order to add it to the TelDir or it is just a matter using the key appearances with the fake DN. Grateful if someone can help with the initial steps of creating a phantom extension before assigning it to any rerouting
