Verifying the Toll Fraud Prevention Configuration
After the configuration is complete, check whether an inter-office user can log in to the enterprise PBX through the Internet, whether a user makes an outgoing call by calling the IVR or through a trunk, whether an unauthorized user can be registered with the PBX, and whether call forwarding can be implemented when call forwarding conditions are not met.
- An inter-office user cannot log in to the enterprise PBX through the Internet.
- An inter-office user calls the IVR, but outgoing calls cannot be made. For example, when an inter-office user calls the IVR, performs second-stage dialing, and dials a number, the call fails.
- When an inter-office user dials the intra-office call prefix + inter-office call prefix + toll call number, the toll call fails. For example, user C cannot make a call by dialing 0 + 00 + 001123456789.
- A user cannot be registered with the PBX through no-authentication or an IP address not whitelisted, or cannot log in to the self-help service through the default password.
- Call forwarding cannot be implemented when call forwarding conditions are not met. For example, call forwarding is performed at work hours. Call forwarding cannot be implemented at off-work hours.
