You dont need any thing special on the router to receive RDNIS. For RDNIS to be passed from the gateway to other entities in Callmanager, you have to check the option "Redirect Number IE Delivery-Inbound" under the H323 gateway configuration page in Callmanager. To send RDNIS outbound, you have to check the option "Redirect Number IE Delivery - Outbound" option under the gateway.
Here is a sample Debug isdn q931 output that shows rdnis being delivered on a PRI
