Call screening based on domain

In this example, user fred will not accept calls from anyone at annoying.com, or from any
unauthenticated users. All other users will allow any calls.

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.
<?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="destination">
<address regex="(.*)@example.com">
<proxy>
<failure>
<!-- Failed to contact using example.com, retry the request with
example.net -->
<taa:location clear="yes" regex="(.*)@example.com"
replace="\1@example.net">
<proxy/>
</taa:location>
</failure>
</proxy>
</address>
</address-switch>
</taa:routed>
</cpl>
