Number substitution on the calling router
As shown Figure 26, the calling router performs number substitution for a number as follows:
1. The router matches the number against number substitution rules on the voice interface. If a match
is found, the router replaces the number based on the matching rule.
2. If the match fails, 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.
3. If no match is found, the router selects a matching voice entity, and replaces the number based on
the matching rule on the voice entity.
4. The router initiates a call to the called side.
