In Scam, Hacker from your main phone number or a toll-free number and ask the receptionist to transfer him your extension 900. In most business telephone systems, is a row to reach 9 codes and 00 is the number of international operators. If transferring phone receptionist, he connected with international operators and supports Caller soft and its relation to international numbers. your business to pay for fraudulent calls.
How this scam works.
Many hackers / can not understand that all closed systems because of the attacks. It's easy to call your number and ask to be great for the relocation of the extension 900. Many companies have the extension 900. Many companies started to ANY number 9. Figures 9 is almost always only used to get the line out. The caller was so successful as to be transferred 900 from the phone, he connected with international operators. Actual code is: 9 (outside line) + 00 (international operator).
A good receptionist will understand that there is no extension 900. They usually know most of their expansion into the heart. If the receptionist told the caller that they don t have the 900, the caller will say something about the plan said the company chairman to request an extension and was waiting for his call. If the receptionist confirmed that there is no extension of the caller 900 may well try to threaten and intimidate him to transfer the call.
How to Protect Your Business
The most important thing is to educate your end users, especially the receptionist or operator. Given the receptionist who doesn t have the answer to the call to make this work. For example, if you can dial the number directly to the office of each building, you can ask someone else to move you. It could be a store clerk or a janitor, it does not matter. So be sure to educate your users at least once a year.
Here are some things that you leave this kind of attack.
1) Block asked 9-00. If your company does not need to contact the international operator, it must be blocked. I also include all international calls (9-011) if it is not necessary to ask the operator to block it. If you need to make calls on those rare occasions, then use the Prepaid Calling Card. You can find some good deals with this card and you have an obligation to limit your losses.
2) Block any Naughty Naughty by calling. If a call comes into the PBX or Key System, and you transfer back out, which is the root to the trunk call is also called tandem calls. This can be blocked on many systems. Keep thinking how this may affect: whether you call them secretaries and officials and to transfer the number out? Do you have service hours after the caller needs to be transferred outside the service? If you don t need to do these things then you should block the trunk to trunk calls.
3) from prevention to be able to transfer callers to external numbers. You will need this feature for some people, but certainly not everyone needs it. Working for retailers for your phone system to assign service classes to block this capability.
4) find areas you can call call. Are any of your business phone, you need to call an international number, or even outside the region number of your business? If no phone calls because the area outside your business, then why provide access to power? If you can not dial long distance you can not transfer a fraudulent caller ID and remote.
5) Monitor your phone bill. It's easy to get away with toll fraud if you never Scam check your phone bill. You need to find a general call.
6) Finally, make sure your phone retailer who knows the number of victims of fraud. This may be surprising given that they must be experts, but I ve met a lot of craftsmen who really don t think about such things. Many who had never even the most basic training on the safety of toll fraud. I ran in one of the technicians that he had great respect for our customers though. I have a trunk to trunk transfer is enabled on the class of service and voice mail systems, he stressed that the abolition. Nilivyoeleza why when he asked why anyone would do that? Now you know to make sure your vendors are doing.
