Intercept

Lawful Interception

The CommuniGate Pro Server implements lawful interception - the functionality that plays a crucial role in helping law enforcement agencies to combat criminal activity.

The Server Administrator can specify the names of CommuniGate Pro Accounts that should be monitored. All login operations with those Accounts, as well as all message manipulation activity in those Accounts is reported via E-mail messages sent to the specified addresses.

The reports can be sent to external programs via the PIPE module. Those programs can convert the reports generated with the CommuniGate Pro Server into the format required by the local law enforcement agencies.

Configuring Interception Settings

To configure the Interception settings, open the Intercept page in the Master realm of the WebAdmin Interface:
Account Name Send Reports to Login Signals New Mail Sent Mail Mailbox Access Partial

To add an element to list, fill the Account Name field in the last empty row and specify the E-mail address to send the reports to, select the checkboxes for the reports your want to generate, and click the Update button.

To remove an element, enter an empty line into the Account Name field and click the Update button.

In a Dynamic Cluster environment, the links for Server-wide and Cluster-wide pages appear. Enter the account names on the Cluster-wide page if accounts belong to Shared Domains served by the entire Cluster.

Note: If an element with an Account name has been added, removed, or modified, and the specified Account is currently in use, the changes will take effect on that Account within 1 minute.
