In order to use IDIH, a remote server connection must be configured. The Communication Agent -> Configuration -> Remote Servers screen on the NOAM is used to configure connections to remote servers.
Once a remote server with IDIH is configured on the NOAM, the IP address for the server will appear in the IDIH IP Address field on the Diameter -> Configuration -> Options screen on the SOAM.
For detailed information about configuring remote servers in DSR, refer to the Communication Agent User's Guide.
