SECURITY ALERT:
Social Engineering — “Social Engineering” is a con game that hackers frequently use.
It is sometimes referred to as “Operator Deceit.” The success of this con requires
gullibility or laxity on the part of the operator or employee, of which the hacker takes
full advantage. For example, hackers call an employee, claim to have the wrong
extension number, and ask to be transferred back to the operator. To the operator, the
call appears to be an internal call. The hacker then asks for an outside line. Often,
because operators are not trained about toll fraud, they will connect the hacker to an
outside line. Another example of social engineering is when a hacker calls the operator
and pretends to be a telephone maintenance repair person. They make statements such
as: “This is Lucent Technologies testing your lines. Please transfer me to 900 or 9#,”
or “I need to verify your DID number range.” An untrained operator may provide the
requested transfer or information, giving the hacker more ammunition with which to
crack your system.
You can transfer calls to an extension or to an outside number. Some of the
reasons to transfer a call include the following:
■
A person on an incoming call (from outside the hotel) wants to be
connected to a user on the server.
■
A user calling the attendant wants to be connected to another user, but they
does not know the extension.
■ A user wants to be connected to an outside number.
■
A person on an incoming call wants to be connected to an outside number,
on another trunk.
To transfer a call, perform the following:
1. Answer the incoming call. Tell the calling person that you are going to
transfer their call.
2. Press the START button.
■
You hear a dial tone.
■
The Split lamp goes on.
3. Dial the number for the person to whom you want to transfer the call.
■
You hear a ringback tone.
■ The display shows the extension you are calling.
