Executive Summary

The Calling Line Identification (CLID) feature allows a CS1000 or Meridian 1 telephone to send a caller's telephone number to the called party. The presentation of CLID information is of particular importance when the caller dials an emergency number. This white paper describes a two-part process used to define CLID information for both emergency and non-emergency calls. The first part of the process involves defining the number(s) that will be sent to the called party. This is commonly referred to as defining a CLID entry. The second part of the process involves assigning the CLID entry to an analog telephone or to a key on a digital or IP telephone.
