 During the interception, two outgoing calls toward an interception [[NAP]] will be placed, each containing a copy of the audio of one direction of the intercepted call. The specified [[NAP]] must be configured to point to the Law Enforcement Agency, generally using ISDN trunks.
-In addition, information records (containing general call information like calling/called number, timestamps, and call duration, etc., this information is called [[Intercept Related Information]] ([[Intercept Related Information|IRI]]) records) will be sent to the Law Enforcement Agency.
