CPL Reference
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 rst 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 eld="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>
