This document provides a step-by-step guide for setting up SIP trunking between two KX-NS PBX systems to allow calls between them while displaying correct caller ID information. It outlines 26 programming steps to configure the PBXs, including assigning IP addresses and ports, enabling SIP registration, setting DDI, CLIP, dialing plans and more. Upon completion of the setup, calls can be made between extensions on either PBX and the correct caller ID will be displayed for the calling party. Revisions were made to the document on three dates to update pictures and explanations.
