Block Calls to Specific Number on MRA

[RAMEEZ RAHIM]

Hi 

I have a MRA deployed with a pair of Expressway Core and Edge.

I want to enforce a policy that would not allow the user to dial any number starting with "9" when the user is out on internet (via MRA)

The same user when on the internal network will be able to dial that number.

I am looking, if there is an option to use the CPL in the Expressway.

It looks the below CPL doesn't take effect. I assume MRA calls bypass the user-define CPL's and Search Rules.

Any Ideas to get this done in the Expressway would be highly appreciated.

<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>
<!--Deny calls to Alias starting with 9 -->
<taa:rule originating-zone="DefaultZone" destination="(9).*">
<reject status="403" reason="Denied by policy"/>
</taa:rule>
</taa:rule-switch>
</taa:routed>
</cpl>

Because it's not expressway who is handling the call routing, they simply proxy all that back to CUCM, and CUCM, just as with any other device, will handle call routing via CSS and partitions.

One alternative, would be to use device mobility, as those devices will always register using the EXP-C IP
