Example Searches and Transforms
You can use pre-search transforms and search rules separately or together. You can also define multiple search rules
that use a combination of Any alias and Alias pattern match modes, and apply the same or different priorities to each
rule. This will give you a great deal of flexibility in determining if and when a target zone is queried and whether any
transforms are applied.

This section gives the following examples that demonstrate how you might use pre-search transforms and search
rules to solve specific use cases in your deployment:

Filter Queries to a Zone Without Transforming
You can filter the search requests sent to a zone so that it is only queried for aliases that match certain criteria. For
example, assume all endpoints in your regional sales office are registered to their local Cisco VCS with a suffix of
example, assume all endpoints in your regional sales office are registered to their local Cisco VCS with a suffix of
@sales.example.com
. In this situation, it makes sense for your Head Office VCS to query the Sales Office VCS only
when it receives a search request for an alias with a suffix of
@sales.example.com
. Sending any other search requests
to this particular VCS would take up resources unnecessarily. It would also be wasteful of resources to send search
requests for aliases that match this pattern to any other zone (there may be other lower priority search rules defined
that would also apply to these aliases). In which case setting On successful match to Stop means that the VCS will
not apply any further (lower priority) search rules.

To achieve the example described above, on your Head Office VCS create a zone to represent the Sales Office VCS,
and from the Create search rule page (Configuration > Dial plan > Search rules > New) set up an associated search
rule as follows:
