What is Toll Fraud
Toll fraud describes a crime where an individual or organisation devises methods to breech PBX Security and gain unauthorised access to PBX resources, including the ability to dial long-distance calls through the PBX. Once access is gained, this can lead to very large telephone bills, accumulating in a period of days or even hours. This can go undetected until a business receives their next phone bill, the cost of which they are liable to pay. With criminals continually finding new and more complex ways of hacking, toll fraud results in UK Businesses losing in excess of £1 billion a year.
Toll Fraud – Ensure you’re aware of what your business is responsible for:
Freedom Communications/Gamma Line Customers with protection:
Automatically limit the spend on any call destination to £500
If any of your phone numbers spend more than £500 in any consecutive 24 hour period on traffic to a single call destination (eg Somalia, or NGCS SC005) which is not UK geographic or UK mobile we will cut it off immediately. Don’t worry; we can easily turn it on again.
Offer peace of mind
No matter how big a bill a fraudster can run up, we will not charge you more than £500 per call destination per 24 hour period.
Important: The above protection only applies if the calls are made over the Gamma network. Should calls be redirected from Gamma through to any other network, this protection does not apply.
All Freedom Communications (U.K.) Ltd customers for which the above does not apply are not covered by Fraud Protection, and Freedom Communications (UK) Ltd. does not accept liability for any fraudulent activity involving their telephone system. For further information on how you can secure your telephone system, or to discuss our Toll Fraud Protection scheme, please contact our Sales Support team on 01923 654220.
Protecting Your Business – Ten Tips
1. Change your PBX Admin Passwords from the default manufacturer ones.
2. If you do not need to make trunk to trunk calls (usually needed for conference calling facilities and for voicemail follow me features) disable this feature, or at least disable it for the extensions that do not need to make these types of call.
3. If you need to make trunk to trunk calls on the voicemail or on the extensions, set some destination restriction on your phone system so that only certain destinations can be dialled.
4. If you do not need to make international or premium rate calls ask your network operator to bar these types of call.
5. Make sure your voicemail administrator and user passwords are not left default. Also, change your user passwords to more complex, non-sequential ones every 90 days.
6. Delete all un-used voicemail boxes.
7. Make sure that if your phone system needs to be accessible via the internet, then you protect this access via a secure method such as a VPN or by locking the access to come from specified IP addresses only.
8. Make sure all IP extensions are protected with a strong password.
9. Delete all un-used IP Extensions.
10. Consider a voice firewall, that can block calls to certain known fraudulent destinations
