Introducing Malicious Call Identification
Malicious Call Identification (MCID), an internetwork service, allows users to initiate a sequence of events when they receive calls with a malicious intent. The user who receives a disturbing call can invoke the MCID feature by using a softkey or feature code while connected to the call. The MCID service immediately flags the call as a malicious call with an alarm notification to the Cisco Unified CallManager administrator. The MCID service flags the call detail record (CDR) with the MCID notice and sends a notification to the off-net PSTN that a malicious call is in progress.
The system supports the MCID service, which is an ISDN PRI service, when using PRI connections to the PSTN. The MCID service includes two components:
•
MCID-O—An originating component that invokes the feature upon the user's request and sends the invocation request to the connected network.
•
MCID-T—A terminating component that receives the invocation request from the connected network and responds with a success or failure message that indicates whether the service can be performed.
Note
Cisco Unified CallManager supports only the originating component at this time.
Using the Malicious Call ID Feature with Cisco Unified CallManager
The MCID feature provides a useful method for tracking troublesome or threatening calls. When a user receives this type of call, the Cisco Unified CallManager system administrator can assign a new softkey template that adds the Malicious Call softkey to the user's phone. For POTS phones that are connected to a SCCP gateway, users can use a hookflash and enter a feature code of *39 to invoke the MCID feature.
When the MCID feature is used, the following actions take place:
1.
The user receives a threatening call and presses the Malicious Call softkey (or enters the feature code *39).
2.
Cisco Unified CallManager sends the user a confirmation tone if the device can play a tone—and a text message on a phone that has a display—to acknowledge receiving the MCID notification.
3.
Cisco Unified CallManager updates the CDR for the call with an indication that the call is registered as a malicious call.
4.
Cisco Unified CallManager generates the alarm and local syslogs entry that has the event information.
5.
Cisco Unified CallManager sends a MCID invocation through the facility message to the connected network. The facility information element (IE) encodes the MCID invocation.
6.
After receiving this notification, the PSTN or other connected network can take actions, such as providing legal authorities with the call information.
System Requirements for Malicious Call ID
Malicious Call ID service requires Cisco Unified CallManager 5.0 to operate.
The following gateways and connections support MCID service:
•
PRI gateways that use the MGCP PRI backhaul interface for T1 (NI2) and E1 (ETSI) connections
•
H.323 trunks and gateways
The Cisco SIP and SCCP IP Phones support MCID by using the Malicious Call Trace softkey in the Standard User softkey template.
The Cisco ATA 186 analog phone ports support MCID by using the feature code (*39).

Conference Calls
When a user is connected to a conference, the user can use the MCID feature to flag the call as a malicious call. Cisco Unified CallManager sends the MCID indication to the user, generates the alarm, and updates the CDR. However, Cisco Unified CallManager does not send an MCID invoke message to the connected network that might be involved in the conference.
Extension Mobility
Extension mobility users can have the MCID softkey as part of their user device profile and can use this feature when they are logged on to a phone.
Call Detail Records
To track malicious calls by using CDR, you must set the CDR Enabled Flag to True in the Cisco CallManager service parameter. When the MCID feature is used during a call, the CDR for the call contains "CallFlag=MALICIOUS" in the Comment field.
Alarms
To record alarms for the MCID feature in the Local Syslogs, you must configure alarms in Cisco Unified CallManager Serviceability. Under Local Syslogs, enable alarms for the "Informational" alarm event level.
When the MCID featured is used during a call, the system logs an SDL trace and a Cisco Unified CallManager trace in alarms. You can view the Alarm Event Log by using Cisco Unified CallManager Serviceability. The traces provide the following information:
•
Date and time
•
Type of event: Information
•
Information: Malicious Call Identification feature gets invoked in Cisco Unified CallManager
•
Called Party Number
•
Called Device Name
•
Called Display Name
•
Calling Party Number
•
Calling Device Name
•
Calling Display Name
•
Application ID
•
Cluster ID
•
Node ID
Refer to the Cisco Unified CallManager Serviceability Administration Guide for more information about alarms and traces.
Restrictions
The following restrictions apply to Malicious Call Identification:
•
Cisco Unified CallManager supports only the malicious call identification originating function (MCID-O). Cisco Unified CallManager does not support the malicious call identification terminating function (MCID-T). If Cisco Unified CallManager receives a notification from the network of a malicious call identification, Cisco Unified CallManager ignores the notification.
•
MCID does not work across intercluster trunks because Cisco Unified CallManager does not support the MCID-T function.
•
Cisco MGCP FXS gateways do not support MCID. No mechanism exists for accepting the hookflash and collecting the feature code in MGCP.
•
MCID does not work over QSIG trunks because MCID is not a QSIG standard.
•
The Cisco VG248 Analog Phone Gateway does not support MCID.
•
Skinny Client Control Protocol (SCCP) IP phones use a softkey to invoke the MCID feature.
See the"Configuring Malicious Call ID" section for configuration details.
Installing Malicious Call ID
Malicious Call Identification, which is a system feature, comes standard with Cisco Unified CallManager software. MCID does not require special installation or activation.

Malicious Call ID Configuration Checklist
Table 12-1 provides a checklist for configuring Malicious Call Identification. You must configure the softkey template and assign the template to an IP phone to make the feature available to IP phones.
Setting the Service Parameter for Malicious Call ID
To enable Cisco Unified CallManager to flag a CDR with the MCID indicator, you must enable the CDR flag. Use the following procedure in Cisco Unified CallManager Administration to enable CDR.
Procedure
