The toll-fraud prevention mechanism in Cisco Unified Communications Manager (CUCM) is designed to prevent unauthorized use of the organization's telephony resources. Toll fraud can occur when unauthorized parties gain access to an organization's telephony system and use it to make expensive long-distance calls. The toll-fraud prevention mechanism in CUCM involves several configuration elements, including:
SIP trunk security profile: A SIP trunk security profile is a collection of security settings that are applied to a SIP trunk. These settings include options such as encryption, authentication, and network access control. In the context of toll-fraud prevention, the SIP trunk security profile can be used to restrict access to the SIP trunk to authorized devices and users, and to prevent unauthorized parties from using the SIP trunk to make long-distance calls.
Calling Search Space (CSS): A CSS is a logical grouping of partitions that determine which dial plan elements a device or user can access. In the context of toll-fraud prevention, a CSS can be used to restrict the types of calls that a device or user can make based on their location, job function, or other criteria. For example, a CSS can be configured to prevent users in a particular department from making long-distance calls.
SUBSCRIBE Calling Search Space: A SUBSCRIBE CSS is a CSS that is used to control access to the presence information of other devices and users in the system. In the context of toll-fraud prevention, a SUBSCRIBE CSS can be used to restrict access to presence information based on the location or job function of the user.
Feature control policy: A feature control policy is a set of rules that control the availability of specific telephony features for devices and users. In the context of toll-fraud prevention, a feature control policy can be used to restrict access to specific features, such as the ability to make long-distance calls.
Partition: A partition is a logical grouping of dial plan elements, such as phone numbers, that determine which elements a device or user can access. In the context of toll-fraud prevention, partitions can be used to restrict access to specific types of calls based on the location or job function of the user.
In summary, the two configuration elements that are part of the Cisco Unified Communications Manager toll-fraud prevention are the SIP trunk security profile and the Calling Search Space.
