On-Premises Call Control

A customer reports that Cisco UCM toll-fraud prevention is not functioning correctly, resulting in charges for unauthorized international calls. Which two configuration changes resolve the issue?

Choose two
  • A Use Cisco Unified Border Element to debug the calls.
  • B Disable call forwarding on the phone.
  • C Make the calls route through a firewall.
  • D Mark patterns as off-net or on-net.
  • E Modify the Block OffNet to OffNet Transfer service parameter.
Explanation

Cisco Unified CM prevents a transferred external call from being sent to another external destination when call routing is classified as OnNet or OffNet and the Block OffNet to OffNet Transfer service parameter is enabled. Route-pattern classification identifies the relevant external call paths, while the service parameter blocks transfers between two OffNet gateways or trunks, mitigating toll fraud.
