CPL example: change of domain name
In this example, Example Inc has changed its domain from example.net to example.com. For a period
of time some users are still registered at example.net. The following script would attempt to connect calls
to user@example.com first and if that fails then fallback to example.net.

CPL example: allow calls from locally registered endpoints only
In this example, the administrator only wants to allow calls that originate from locally registered endpoints.
<?xml version="1.0" encoding="UTF-8" ?>
<cpl xmlns="urn:ietf:params:xml:ns:cpl"
xmlns:taa="http://www.tandberg.net/cpl-extensions"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="urn:ietf:params:xml:ns:cpl cpl.xsd">
<taa:routed>
<address-switch field="registered-origin">
<not-present>
<reject status="403" reason="Only local endpoints can use this VCS"/>
</not-present>
</address-switch>
</taa:routed>
</cpl>
CPL example: block calls from Default Zone and Default Subzone
The script to allow calls from locally registered endpoints only can be extended to also allow calls from
configured zones but not from the Default Zone or Default Subzone.
<?xml version="1.0" encoding="UTF-8" ?>
