B and C

Users can exploit the Call Forward All feature (which they can configure through a web interface) and transfer from voice-mail features to make toll calls using the corporate voice network.

A

To restrict external call transfers (which block OffNet-to-OffNet transfers), route patterns and gateways should be classified as OnNet or OffNet. Route patterns are typically used to restrict outbound calls, whereas gateways are used to restrict incoming calls.

A and D

By default, the ad hoc conference restrictions are set to Never, which opens the possibility of toll fraud. You can choose to set the restrictions to When Conference Creator Drops Out or When No OnNet Parties Remain in the Conference to restrict this toll fraud method.

C

Forced Authorization Codes (FACs) allow you to restrict call routing to destinations based on user codes. This is not only useful to prevent toll fraud, but also to determine which users or departments are making toll calls for billing purposes.

B

Commonly exploited countries have special area codes that look like area codes of the United States. Not all international numbers begin with the 011 identifier (in North America). Because of this, you should be especially careful to restrict international area codes using route patterns.

A

The most automated process for installing security updates and hot fixes to the CallManager server is e-mail subscription to the Cisco CallManager Notification Tool. The updates must then be manually downloaded and installed.

B

The correct configuration of time-of-day routing is as follows: create time periods, add the time periods to a time schedule, assign the time schedule to a partition, and assign the partition to a calling search space.

D

Client Matter Codes (CMCs) are typically used to track calls to a specific department or user. However, they do not give you the varying authorization levels of the FAC feature.

A, D, and E

By classifying the route patterns, trunks, and gateways as OnNet or OffNet, you can effectively curb OffNet-to-OffNet transfer toll fraud.
