The Call Content Channel object defines information about the CCCs, including how you want the CCCs to be activated and deactivated. It is a child of the Warrant object.
![]() |
CCCs are allocated separately. If there is not an available CCC at the time when it is requested, the request will simply be dropped. If you choose Separated delivery as your Call Content delivery method in the Warrant object, you will need at least two CCCs (one for each channel) and probably more (for example, in the case of three-way calls). |
![]() |
The EMS will prevent CCC(s) from being deleted in two cases.

Parameter |
Access |
Description |
CCC ID | Create | The CCC ID is a unique ID for the Call Content Channel. It is agreed between the Telecom Service Provider (TSP) and the Law Enforcement Agency (LEA), and is specified on the warrant. |
Deactivation mode | Change | The deactivation type required.
|
LEA directory number | Change inactive | Specify the directory number of the destination of this CCC. This is the number, which the Law Enforcement Agency (LEA) has provided to receive the call content on, and is used to establish the CCC. It is also used to identify the CCC on CDC messages. This number must be a 10 digit national number . |
Carrier ID | Change inactive | Specify the carrier ID (PIC2/PIC1) used for the connection to the CCC DN. This may be the intraLATA carrier code or the long distance carrier code, depending on the DN configured for the CCC. This field may be empty if a carrier ID is not required. Otherwise the length of this field must be 4 digits. |
Connection type | Change inactive | This indicates whether the call content channel will be permanently established, ready to deliver call content, or whether it will only be established when an intercept subject begins a call for which call content should be delivered. Values:
|
Max answer time | Change inactive | This field applies only if Connection type is On demand. Specify the length of time, in milliseconds, that the Law Enforcement Agency has to answer a call on this CCC before a tap is abandoned. This time starts from when an attempt is made to set up the CCC, and continues until the CCC is answered. Default: 10000 ms (10 seconds). |
Bearer capability | Change inactive | Bearer capability (type of ISDN calls) for which this channel is to be used. Each channel can carry call content of only one type. This field is valid only if the subscriber's Call Agent signaling type is set to ISDN PRI.
If Call Content delivery method in the Warrant object is set to Combined delivery, this field must be set to Speech or 3.1kHz audio, because data cannot be carried on a combined channel. Otherwise, you can set up separate channels for each type of call content that you want to collect. To collect data of either type (64kbps or 56kbps), you must set up at least two Call Content Channels with the same bearer capability, one for each direction of data flow.
