Lawful Intercept on the Cisco 12000 series router conforms to the following standards and MIBs.

Service Independent Intercept (SII) architecture 

Simple Network Management Protocol Version 3 (SNMP V3)

CISCO-TAP-MIB, Version 1

Voice over IP (VoIP) Lawful Intercept provisioning is based on the local media gateway IP address and 
the UDP port. The mediation device uses the CISCO-TAP-MIB to provision Voice over IP (VoIP) 
intercepts. In Voice over IP (VoIP) Lawful Intercept provisioning, an intercept can be enabled or disabled 
during a voice call.

Dial-up Lawful Intercept provisioning does not have fixed IP addresses. The IP addresses are assigned 
dynamically. The mediation device uses the CISCO-TAP-MIB to provision dial-up intercepts.

Before you can provision Lawful Intercept on a Cisco 12000 series router, you must have the following 
components already set up:

SNMP server with VACM views

Mediation device
