5.2. Zone Transforms
It is possible to direct an incoming location request to a different alias by replacing either the prefix or
the suffix of the alias with a new string.
Zone transform rules are created either:
using the xconfiguration zones set of commands, or
using the web interface when adding or editing a zone via Gatekeeper Configuration > Zones.
You must first select from the Match 1, Match 2, etc. sections a Mode of PatternMatch in order
to access the options (see Figure 4).
Zone transforms support the use of Regular Expressions. See Appendix C for more information.
Example
Endpoints might be registered to a Gatekeeper with aliases of the form user@example.com. If someone
were to dial user@exampleusa.com we might want to try and find that user as user@example.com,
hence we need a rule that replaces the suffix exampleusa.com with example.com before searching off
the box. This can be achieved by configuring the zone transforms as shown in Figure 8:
