Type display trunk-group x, where x is the number of the trunk group.
The system displays the Trunk Group screen.
Scroll down till you see the Send EMU Visitor CPN field.
This field controls calling party identification, that is, the extension of the primary telephone or the extension of the visited telephone that is used when a call is made from a visited telephone.
If you want the system to display calling party information of the primary telephone, the Send EMU Visitor CPN field must be set to y. There are areas where public network trunks disallow a call if the calling party information is invalid. In this case, there can be instances where the extension of the primary telephone is considered invalid and the extension of the visited telephone must be used. To use the extension of the visited telephone, set the Send EMU Visitor CPN field to n.
Note:
If you set the Send EMU Visitor CPN field to y, you must set the Format field on the same page to either public or unk-pvt.
