Malicious Call Trace Control

Last Updated : Sep 03, 2022 |

When a user activates the mct-act button, the system notifies the potential MCT controllers. A potential MCT controller is a station or an attendant that has an mct-contr button.

Note:

The mct-contr button can only be administered on H.323 or DCP stations or attendants. This functionality is not SIP compatible. If no mct-controller is administered, then the SNMP trap is generated to record the MCT activation.

To notify the potential MCT controllers, the system:

  • Generates an alert tone.

  • Flashes the indicator of the mct-contr button.

The user who presses the mct-contr button first becomes the MCT controller of the call. The system stops alerting other potential MCT controllers.

  • The called number

  • The activating number

  • The status of the call

  • The details of the other parties on the call

The user of the MCT controller must continue to press the mct-contr button to see the entire MCT information.

Depending on the origin of the call, the system displays:

  • The calling number if the call originates inside the system or on the same node within a Distributed Communications System (DCS) network.

  • The calling number if the call originates outside the system and an Integrated Services Digital Network (ISDN) or SIP calling number identification is available on the incoming trunk.

  • The location of the incoming trunk for all other calls. In this case, the user must call the connecting server to get more information about the malicious call.
