Strip incoming CLID from PSTN to specific IP phones

[Robert Rhodes]

Is it possible to strip incoming CLID received from the PSTN on only a selected subset of CUCM controlled DNs? Here's the use case:

The customer has phones inside a restricted facility (detention center). They do not want CLID displayed on certain phones within that facility as that may provide inappropriate access to personal information. They are concerned only about name/number coming from the PSTN, they have no concern about on-net display of other CUCM controlled DNs. CLID from the PSTN must be available to all other CUCM controlled devices so this cannot be a global change. 

Inbound calls are received across multiple PRIs in PRI groups split between multiple h.323 gateways. Attempting to restrict or strip CLID at the dial-peer level would be cumbersome. The DNs to which this should be applied are also not contiguous, complicating the use of wildcards in configuration. The version of CUCM is 10.5.2.

Any thoughts or suggestions?

You could look into a TCL script to do this, host it in a separate server so it can be managed in just one place, and then you would need to configure it for all the DNs you don't want to get calling info.

Thanks. I was hoping to be able to do this within CUCM but it looks as if that would only apply outbound.
