The parameter liPolDipForRegdOodMsg when enabled is used to indicate SBC to send policy request to PSX for registered Out-Of-Dialog requests(messages) to be intercepted. When this parameter is disabled, policy request is not sent to PSX for registered Out-Of-Dialog requests (messages).
Enable the support for Policy dip, for registered users out-of-dialog messages, to decide on interception, by executing the command
