Bridged Call Appearance

The system records the primary extension as the Malicious Call Trace recipient when the feature is activated at a bridged call appearance, or for a bridged call appearance.

Conference

A user can use conferencing to place a malicious caller on hold. The user can start a conference, dial the Feature Access Code (FAC) that activates Malicious Call Trace, and then stop conferencing and return to the call appearance of the malicious caller.

The feature can also be activated for a member of a conference. The Malicious Call Trace activation is unaffected by the number of parties on the conference.

Centralized Attendant Service

The activation, control, and deactivation of Malicious Call Trace for a call must occur on the same server.

Distributed Communications System

If a telephone in a Distributed Communications System network is involved in a malicious call, the system records and displays the extension with the Malicious Call Trace information. Malicious Call Trace notification passes over ISDN-PRI DCS trunks, but the activation, control, and deactivation of Malicious Call Trace must be performed by telephones that are on the same Distributed Communications System node.

Emergency Access to the Attendant

Usually, during MCT-Control, no other feature can access the display of the controlling telephone. However, Malicious Call Trace gives up control of the display until an Emergency Access call is completed.

Make-Busy/Position-Busy/Send All Calls

The software attempts to activate Make-Busy or Position-Busy for telephones or consoles that activate MCT-Control. If a user has a Send All Calls (SAC) button administered but inactive for the primary extension on the phone, SAC is activated when the user activates MCT-Control. When the user deactivates Malicious Call Trace, SAC remains active until the user deactivates SAC.

Music-On-Hold

If an agent places a malicious call that is being recorded on hold, and the call goes to music-on-hold, the music-on-hold port and the MCT voice recorder port can get locked too long In this case, the Malicious Call Trace voice recorder continues to record the music-on-hold and is unavailable to record subsequent malicious calls. You must busy out or release the Malicious Call Trace voice recorder port to drop the connection.

Priority Calling

The system denies a priority call to an Malicious Call Trace recipient.

QSIG Global Networking

Malicious Call Trace notification passes over tandem, tie, access, and DMI-BOS ISDN QSIG trunk groups. The name and number ID of the QSIG supplementary services provide the name and telephone number of a malicious caller.

SIP Trunks

Malicious Call Trace notification passes over SIP trunk groups through Session Manager to a Session Border Controller. The Session Border Controller can adapt the Malicious Call Trace notification to the format required by the SIP service provider.

Transfer

If a user transfers a malicious call, the Malicious Call Trace information that the system displays on the telephone of the Malicious Call Trace controller identifies the party that is transferred as the Malicious Call Trace recipient.

Trunk Access Code (TAC)

To activate Malicious Call Trace for a TAC, a user must have an mct-contr feature button administered. The user hears a dial tone and enters the trunk-member number for the trunk group that the TAC identified. The user then becomes the Malicious Call Trace controller for a call that involves the identified trunk member. This TAC operation is useful when users must trace a call that tandemed through their server or toggle to terminate on another server or switch.

Trunk groups

If a personal central office line is involved in a malicious call trace, the software might hold up the trunk until the Malicious Call Trace is deactivated.
