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, or by using regular expressions to specify the way in which the
alias is to be transformed.
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
Border Controller 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 [email protected]. If someone
were to dial [email protected] we might want to try and find that user as [email protected],
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:
