The MPTA reported this scam about a year ago, but it seems that it's back!
Beware of any phone call where the caller asks you to touch nine (9), zero (0) and then the pound sign (#) - HANG UP IMMEDIATELY!
This scam, if you do as asked, gives the requesting individual full access to your telephone line which enables them to place long distance calls that are billed to your phone number.
Most of these calls are originating from prisoners in jail.
This information has been verified with UCB Telecom, Pacific Bell, MCI< Bell Atlantic and GTE Security Department.
Remember DO NOT PRESS 90# FOR ANYONE!
