Note

To create CDC, refer to the section Configuring SBC For Lawful Interception.

Code Block
languagenone
% set addressContext default intercept callDataChannel CDC ipInterfaceGroupName LIG1
commit
Note

Mediation server’s ipInterfaceGroup must be different from other signaling ipInterface groups. This ensures that LI doesn't use signaling ipAddress to send intercepted traffic (media/signaling) towards Mediation Server.

Configuring CDC for "Li Pol Dip For Regd Ood Msg"

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

Code Block
languagenone
% set addressContext default intercept callDataChannel CDC liPolDipForRegdOodMsg enabled
commit
Note

The liPolDipForRegdOodMsg  parameter is visible, when interceptStandard and vendorId is configured as IMS LI.
