4000 Router Series Voice Configuration Guide

Number substitution on the called router

As shown Figure 26, the called router performs number substitution for a number as follows:

1. The router matches the number against global number substitution rules. If a match is found, the

router replaces the number based on the matching rule.

2. If no match is found, the router selects a matching voice entity, and matches the number against

rules on the voice entity. If a match is found, the router replaces the number based on the matching

rule.

3. If no match is found, the router calls the called number if the callee is a local subscribe line, or

initiates a call to the PSTN if the callee is in the PSTN.
