Thanks for the information. For clarification, my issue is with calls from PSTN to IP; I want to be able to show display names for incoming calls from PSTN to IP. If there is no set defined way in Q.931 for Calling Party Name Delivery, how do we get it then? Are there any PRI gateways that can decode various delivery methods? Are there any CNAM databases that we can use?
