This same scam could also easily apply to messages left on voice
mail. The person could state, “I’m John Doe calling from XYZ.
Please return my call at 212-540-xxxx.” When you return the call,
you are charged $50.00.
Another slant to this scam is carried out by messengers who deliver
parcels to your office. They will ask to use your company’s phone to
call their office. Then they call one of these 976-look-alike numbers
and stay on the line for a minute or two. Your company then gets the
bill for a $250 call that lasted only a couple of minutes.
— Internal Abuse
Unfortunately, not all toll fraud is generated from “outsiders.” Many
times it can be traced to internal employees who either sell the
information or abuse the system for their own gain.

Call Forwarding Off-Premises
Call forwarding can be programmed to forward calls internally
(within the PBX) or off-premises. If off-premises call forwarding is
allowed, unscrupulous employees can take advantage of it. They
forward the phone to a number (usually their home number). They
tell their friends and family to call the company’s 800 number and
insert the employee’s extension number. The call is forwarded to the
employee’s home phone, and the company foots the bill for the call.
