CPL Examples

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.

<?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 is="fred">

<address-switch field="origin" subfield="host"> <address subdomain-of="annoying.com">

<!-- Don't accept calls from this source -->

<!-- Reject call with a status code of 403 (Forbidden) --> <reject status="403" reason="Denied by policy"/>

</address> <not-present>

<!-- Don't accept calls from unauthenticated sources --> <!-- Reject call with a status code of 403 (Forbidden) --> <reject status="403" reason="Denied by policy"/>

</not-present> <otherwise>

<!-- All other calls allowed --> <proxy/>

</otherwise> </address-switch>

</address> </address-switch>

</taa:routed>

</cpl>

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>
