On-Premises Call Control

A recent audit identified incidents of toll fraud. Restrictions must use Cisco UCM class-of-service and supplementary-services features. Which two Cisco UCM actions prevent additional toll fraud?

Choose two
  • A Implement a class of restrictions on the gateway.
  • B Implement transformation pattern for all off-net calls.
  • C Set the service parameter to block off-net to off-net transfers.
  • D Restrict international patterns on SIP trunk CSS to the gateway.
  • E Set the call forward all CSS to restrict international patterns.
Explanation

Setting the Block OffNet to OffNet Transfer service parameter to True blocks transfers from one external (OffNet) device to another, preventing a common toll-fraud path. A Call Forward All calling search space that excludes international route patterns restricts forwarded calls from reaching international destinations; Unified CM uses that CSS to validate and route the Forward All destination.
