CPL Examples

Restricting Access to a Local Gateway

In these examples, a gateway is registered to the VCS with a prefix of 9 and the administrator wants to stop calls from outside the organization being routed through it.

We can do this in two ways: using the address-switchnode or the rule-switchnode. Examples of each are shown below.

Using the address-switch node

<?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="9(.*)">

<address-switch field="originating-zone">

<!-- Calls coming from the traversal zone are not allowed to use this gateway -->

<address is="TraversalZone">

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

</address> </address-switch>

</address> </address-switch>

</taa:routed>

</cpl>

Using the rule-switch node

<?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> <taa:rule-switch>

<taa:rule originating-zone="TraversalZone" destination="9(.*)"> <!-- Calls coming from the traversal zone are not allowed to use

this gateway -->

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

</taa:rule>

<taa:rule origin="(.*)" destination="(.*)"> <!-- All other calls allowed --> <proxy/>

</taa:rule> </taa:rule-switch>

</taa:routed>

</cpl>
