How can a route pattern be used to prevent toll fraud?

By limiting the number of concurrent calls

By encrypting the call signaling

By defining a route pattern that matches only authorized destinations

By authenticating the caller with a PIN

A global law firm has Cisco UCM deployed with a centralized PSTN gateway in the main office. Remote offices connect to the main office via a site-to-site VPN. The firm's security team is concerned about toll fraud via the PSTN gateway, especially from compromised devices in remote offices. They want to ensure that only authorized devices can use the gateway and that signaling traffic is protected. Which two measures together provide the most effective defense?

Implement a translation pattern on the gateway that blocks all calls from the remote office area codes.

Configure the gateway to use a shared static password for all remote devices and disable the VPN for remote offices.

Disable the PSTN gateway during off-hours and require all international calls to be placed through a separate toll-free number.

Enable SIP authentication and encryption (TLS) on the gateway trunks and configure the gateway to only accept calls from the IP addresses of the remote office subnets.

A manufacturing company has experienced a toll fraud incident where an attacker used a compromised admin account to modify route patterns and place international calls. The incident response team has restored the system from a backup, but the CFO wants to ensure this does not happen again. The company has a small IT team and limited budget. Which combination of best practices should be implemented to prevent a recurrence?

Upgrade the PSTN gateway firmware and enable SIP TLS.

Implement role-based access control (RBAC) to limit admin privileges, enable audit logs, and schedule regular reviews of route patterns and CDRs.

Change all admin passwords and disable the built-in admin account.

Implement a translation pattern that blocks all international calls and require a ticket for any international call.

A company has experienced a toll fraud incident and wants to implement best practices to prevent future occurrences. The IT manager has a limited budget and wants to prioritize actions. Which action should be implemented FIRST?

Change all user passwords and require a password change every 30 days.

Disable all international calling and require a written request for any international call.

Enable CDR logging and schedule regular reviews of the CDR reports.

Purchase and deploy a new firewall with intrusion prevention capabilities.

What is the purpose of a translation pattern in Cisco UCM?

To authenticate users before they can make calls

To block all calls to a specific gateway

To manipulate the dialed digits before further routing

To define the codec used for a call
