Least Cost Routing/Destination Restriction
The programs that follow control Strata CTX's Least Cost Routing (LCR) and Destination Restriction
(DR) capabilities.

LCR/DR Overview

Programming LCR/DR features in Strata CTX requires an advanced knowledge of telephone
programming. Make sure you have a thorough understanding of the discussion that follows before
attempting to program these features. For details on DR, see
LCR Analysis Process
The flowchart below represents the process by which Strata CTX analyzes dialed digits and makes LCR
decisions. The graphic is divided into four areas each described below. DR and call connection are
described elsewhere in this document and are shown here only for their roles in the LCR process.
