Configuring Lawful Interception

Applies to: Tmedia 3.0, 3.2, 3.3; SBC 3.1, 3.3

Note: This procedure assumes that a Law Enforcement Agencies NAP has been created. Each Law Enforcement Agency requires that a NAP be configured to send the intercepted call legs. NAPs can be dedicated for lawful interceptions, or not.

To configure a Law Enforcement Agency:

1- Select Lawful Interception from the navigation panel

ConfigureLawfulInterception 0

2- Enter an Indentifier for the Network Operator.

• Click Save

3- Create a Lawful Agency

• Click Create New Lawful Agency

ConfigureLawfulInterception 1

4- Configure the Lawful Agency parameters:

• Click Save.

ConfigureLawfulInterception 2
