If the network has IP trunks or XNET trunks, complete the required trunk programming at each element (see IP Networking Programming).
When programming the ICP/PBX Networking form and XNET ICP/PBX Networking form at each element:
assign the local element a PBX Number. This PBX Number must match the CEID index that you assigned to the element in the Cluster Elements form.
assign a PBX Number to each remote element. The PBX Number that you enter for a remote element must match the CEID index that you assigned to it in its Cluster Elements form.
Proceed to Configure the Telephone Directory Forms.
